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.
