The AFC461 EMI filter will reduce the input line reflected

ripple current of the AHV, ATO, ATW, ATR, and AHF line

of DC/DC converters to levels below the CEO3 limits of

MIL-STD-461.

These EMI filters are manufactured in a facility certified

to MIL-PRF-38534. All purposes used to manufacture

these filters have been qualified to enable Advanced

Analog to deliver compliant devices. Three standards

temperature grades are offered with screening options.

Refer to Part Number section. The CH grade filters are

fully compliant to MIL-PRF-38534 for class H. The HB

grade converters are processed to MIL-PRF-38534

screening but do not have class H element evaluation

as required by MIL-PRF-38534. Two grades are fully

tested and operate over the full military temperature

range without derating of output power. A commercial

grade is also available.

n No Derating for -55°C to +125°C Operation

n No Tantalum Capacitors for High Reliability
