Defence EMI filter modules for MIL-STD-461 compliance

These new modules are designed specifically to help designers meet MIL-STD-461 (F & G) requirements, critical for any equipment deployed in harsh military or aerospace environments.

Why MIL-STD-461 matters

If you’re in the defence space, you’ll know that electromagnetic compatibility (EMC) is essential. MIL-STD-461 defines the standards for:

• CE (conducted emissions) – what your equipment puts out on the power lines
• CS (conducted susceptibility) – what it can take in from noisy power without failure
• RE (radiated emissions) – the electromagnetic field it emits into the air
• RS (radiated susceptibility) – the device’s sensitivity to external radiated electromagnetic interference

In short: it’s about ensuring everything works together, in any conditions or location, without frying each other’s circuits.

The new MF modules: plug, play, pass

Cincon’s MF10D075P and MF20D075P are designed to pair with their eighth-brick and quarter-brick DC/DC converters respectively, including models such as:

• CQB50W8, CEB100W, CQB150W
• ECLB60W, ECLB75W

This plug-and-play approach reduces the need for bulky discrete filtering components (inductors, capacitors, beads), saving development time on EMC compliance while keeping your project compact, cost-effective, and compliant.

Test case: MIL-STD-461, conquered

To demonstrate this, Cincon tested the MF series with all of the above bricks to CE102 of the MIL-STD-461 specification, achieving a pass for all models using their reference circuit and PCB design.

Built for defence

These modules are ready for the extremes, with:

• Operating temperatures from -55°C to +110°C
• Industry standard heatsink and mounting options
• Shock and vibration compliance to MIL-STD 810F

Perfect for avionics, ground vehicles, and any application where electromagnetic chaos is the norm.
