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.
G6E No Derating for -55°C to +125°C Operation
G6E No Tantalum Capacitors for High Reliability
