Cincon, supplied by Relec Electronics, has just bolstered its power portfolio with the release of its MF10 and MF20 defence-grade EMI filter modules, offering engineers an elegant solution to a not-so-elegant problem: electromagnetic compatibility.
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 defence EMI filters, MF10D075P and MF20D075P, are designed to pair with their eighth-brick and quarter-brick DC-DC converters respectively, including models such as:
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 & mounting options
- Shock & Vibration compliance to MIL-STD 810F
Perfect for avionics, ground vehicles, and any application where electromagnetic chaos is the norm.
