Meet the Engineer's Cost Champion.
The cheapest core is often the most expensive magnetic design.

Real cost savings don't come from core price alone. They come from optimizing the entire magnetic solution: core, copper, winding, assembly, footprint, thermal performance, and efficiency.

Recently, we worked with a customer that was using a large ferrite assembly. Rather than simply matching the existing design, our team evaluated a single-piece alternative that could simplify manufacturing while also helping address thermal performance concerns. The opportunity wasn't about finding a cheaper core. It was about reducing complexity and optimizing the total magnetic solution.

That's the difference between buying a core and engineering a solution.

The best question isn't:
"What's the cheapest core?"
It's:
"What's the lowest total-cost magnetic solution?"

Because the best designs don't optimize component cost. They optimize system cost.

EMI problems rarely start with a single component, and ferrites are not a universal fix.

Used correctly, Magnetics' MnZn ferrite cores can dramatically improve noise suppression and system performance. Used incorrectly, they can waste board space while leaving the real issue untouched.

Here are 3 EMI problems ferrites can help solve:

✔ Common-mode noise in power conversion systems
✔ High-frequency conducted emissions on cables and power lines
✔ Noise generated by fast-switching power electronics

And 3 they typically can’t solve on their own:

✘ Poor PCB layout and grounding: ferrite's can't replace correct return paths or geometry
✘ Crosstalk caused by routing issues: ferrites can't fix coupling created by geometry
✘ Low-frequency noise outside the ferrite’s effective range: Ferrite’s usefulness is dependent on frequency, while nanocrystalline materials, with their much higher permeability, can provide effective noise suppression at lower frequencies.
That’s why core material selection matters.

MnZn ferrite cores from Magnetics are engineered for high permeability and effective suppression in high-frequency EMI applications (kHz-tens of MHz) including:

• Common-mode chokes
• Power supplies
• EV and HEV systems
• DC-DC converters
• Industrial power electronics

The best EMI strategy starts by identifying the actual noise mechanism, then selecting the right magnetic material for the job.

The Magnetics Advantage: Looking Beyond Core Cost

A customer developing an EV application needed to reduce space without increasing costs. Their existing design left little room for optimization, and changing suppliers or redesigning the system could have introduced unnecessary expense and requalification risks.

Our Solution: Magnetics proposed a three-stack core configuration that reduced overall height by 1 mm while maintaining the same core cost. Rather than focusing solely on the price of the magnetic component, our team evaluated the complete design and manufacturing impact.

By optimizing the magnetic solution, the customer was able to reduce copper usage and winding requirements without increasing material costs.

The Impact: Lower overall bill-of-material (BOM) costs, reduced manufacturing complexity, and valuable space savings, all while avoiding the costs and risks associated with major design changes or supplier transitions.

Because true cost reduction isn't just about finding a cheaper component, it's about engineering a solution that lowers the total cost of ownership.

Still prototyping inductors the “long way”?

If you're manually iterating designs or digging through datasheets to validate core options, you’re likely adding unnecessary time to your design cycle. A more efficient approach would be the Magnetics’ Inductor Design Tool. Here’s how to use it to accelerate early-stage prototyping:

1. Start with real design inputs
Enter inductance, current, frequency, and your selected powder core material. This anchors your design in actual application requirements from the beginning.

2. Identify optimal size and permeability
The tool quickly determines the smallest core size and most efficient permeability based on your inputs. This helps guide more efficient designs early in the process.

3. Compare designs and analyze performance
Evaluate key tradeoffs such as core size vs. performance, loss characteristics, and temperature behavior. You can also plot a DC bias curve for your selected part number, providing deeper insight into projected performance.

4. Iterate quickly
Adjust parameters and immediately see the impact on performance. This is especially valuable during early prototyping when requirements are still evolving.

5. Move to build, and collaborate, with confidence
Export your finalized design with supporting data, reducing reliance on trial-and-error during validation. You can also use the “Share with Magnetics” feature to connect with our team for technical guidance, quotations, or sample requests.

Why it matters
• Reduces initial design time
• Minimizes iteration cycles
• Improves confidence in core selection

If you're working on switch-mode power supplies (SMPS), output filters, or other power circuits, this tool can significantly streamline your process.

Is your design larger than it needs to be?

It’s a common tradeoff in magnetics design.

To stay within flux density and thermal limits, cores often get oversized. It works, but at a cost.
🔴 Larger inductors
🔴 Increased weight and footprint
🔴 Higher material and system costs

In today’s applications, that tradeoff is getting harder to justify.

From EV power systems to telecom infrastructure and aerospace electronics, the push toward higher power density and miniaturization is only accelerating. Oversized components don’t just take up space, they can limit overall system performance.

So what’s the alternative?

Instead of scaling size, more engineers are rethinking material selection earlier in the design process.

Advanced core materials, like low-loss Kool Mµ Ultra or high-efficiency Edge powder cores enable higher energy handling and improved efficiency in a smaller volume. That means you can meet electrical and thermal requirements without overbuilding the core.

The result:
🔴 More compact designs
🔴 Better thermal performance margins
🔴 Reduced system-level cost

Material choice isn’t just a detail; it’s a design lever.

Shrink your design without compromise.

In a recent 100kW inductor project, a customer evaluated Magnetics' High Flux blocks against a competitive solution. The objective was to achieve demanding inductance and DC bias requirements while maintaining an optimized core design.

The results were clear:
🔹 The competitive solution required a larger core geometry
🔹 Even with the larger core, it failed to meet the application's inductance and DC bias targets
🔹 Magnetics' High Flux delivered the required performance in a more optimized design

This is where material performance makes a difference. By enabling engineers to achieve electrical targets without resorting to oversized magnetic components, High Flux helps optimize both performance and efficiency in demanding power applications.

By focusing on performance-driven design, we help customers:
🔹 Reduce magnetic component size and avoid oversizing
🔹 Improve overall system efficiency
🔹 Achieve demanding electrical performance targets

No matter what next-gen power design you are developing, Magnetics works alongside engineers to deliver magnetic solutions that perform under real-world conditions.

Frequency Matters: How Core Material Selection Changes Above 100 kHz

Once you cross 100 kHz, magnetic design rules start to shift.

Core losses rise quickly, and not all losses scale the same way. While hysteresis loss increases with frequency, eddy current losses rise even faster, making material resistivity a critical factor in high-frequency designs.

That’s where smart material selection makes the difference:

🔹 MnZn ferrites offer offer high resistivity and low core loss at up to 1-3 MHz
🔹 High frequency powder materials such as such as Magnetics' Kool Mµ® family and Edge® are designed specifically to reduce losses in the hundreds of kHz range while handling DC bias
🔹 High-permeability nanocrystalline is preferred in this range when high inductance, compact size, and stability matter most

The takeaway?
Higher frequency doesn’t just shrink designs, it demands better material choices.

At Magnetics, we help engineers match core material to real operating conditions, so performance keeps up as frequency climbs.
