Bourns SRP1024HMCT Inductor Delivers High Current in Compact, Shielded Design

Bourns has just added a new part to its growing family of high-current inductors: the SRP1024HMCT. It’s a shielded, surface-mount inductor built with one goal in mind, power delivery in compact, high-density designs. Think point-of-load converters, data centre blades, and industrial compute platforms, where space is limited and performance needs to be dialled in.

This isn’t a traditional wound-wire component. The SRP1024HMCT uses a hot-pressed carbonyl powder core, which helps push the current ratings up and keeps EMI under control. The result is an inductor that handles serious current, stays quiet, and doesn’t throw off the magnetic noise that complicates compliance testing.

A Quick Look Under the Hood

On paper, the SRP1024HMCT looks straightforward. But a few design decisions give it an edge:

• Saturation currents up to 48 A, depending on the inductance variant
• Low-profile package for boards with tight Z-height restrictions
• Magnetically shielded construction, reducing field radiation
• Buzz-suppressed core to keep acoustic noise in check
• Wide temperature range: –40 °C to +125 °C
• Fully RoHS-compliant and halogen-free

In short, it’s the kind of part suited to high-efficiency, thermally constrained designs.

Application Uses

You’ll typically find these inductors behind DC-DC converter ICs, smoothing current on the power rail or buffering transients from fast-switching loads. They’re also a good fit for networking switches, AI accelerators, and embedded compute modules, systems where every millimetre of board space matters.

The moulded construction also improves mechanical durability, which is a benefit in automotive and industrial designs that see shock or vibration.

Conclusion

The SRP1024HMCT offers a strong combination of current handling, low EMI, and mechanical stability in a compact footprint. Its design is well-suited to modern power delivery challenges, particularly in space-constrained environments like server boards, industrial control systems, and high-performance embedded platforms. For engineers focused on reliability and layout efficiency, it presents a practical, performance-focused solution.
