MF10D075P vs MF20D075P: 10A/20A MIL-STD-461 EMI Filters
The CINCON MF10D075P and MF20D075P are PCB-mounted DC input filter modules designed for vehicle, airborne and other harsh-environment power systems.
Both models support continuous operating voltages up to 75VDC and help reduce common-mode and differential-mode noise produced by DC-DC converters. The main selection difference is current capacity: MF10D075P supports up to 10A, while MF20D075P supports up to 20A.

Which EMI Filter Should You Choose?
Choose MF10D075P when:
Maximum continuous input current is below 10A.
An eighth-brick footprint is preferred.
The filter is paired with lower-power DC-DC converters.
Lower weight and a narrower package are important.
Choose MF20D075P when:
Input current can exceed 10A but remains within 20A.
The system uses a high-power quarter-brick or half-brick converter.
Additional current margin is required at low input voltage.
The PCB and cooling design can accommodate the larger module.
Typical Applications
Military ground vehicles
Airborne electronic systems
COTS defense power supplies
Rugged communication equipment
Battery-powered systems
Distributed power architectures
Industrial DC-DC converter systems
Frequently Asked Questions
1. What is the main difference between MF10D075P and MF20D075P?
MF10D075P is rated for 10A and uses an eighth-brick package. MF20D075P is rated for 20A and uses a quarter-brick package.
2. Does the filter guarantee MIL-STD-461 compliance?
No. It is designed to help the complete power system meet MIL-STD-461F/G requirements. Final compliance depends on the external components, PCB layout, converter, wiring, enclosure and system-level testing.
3. What is the maximum operating voltage?
Both modules support up to 75VDC continuously and a 100VDC transient for up to one second.
4. Can MF10D075P be replaced directly by MF20D075P?
Not without redesign verification. The modules have different dimensions, footprints, current ratings, weights and isolation capacitances.
5. How should the rated current be selected?
Calculate the maximum converter input current at the lowest operating voltage, then include margin for efficiency, startup conditions, transients and temperature derating. Select MF20D075P if the required current may exceed 10A.
