EMI FILTER
AFV461 SERIES
Description
The AFV461 EMI filter will reduce the input line reflected
ripple current of all DC/DC converter families to levels
below the CEO3 limits of MIL- STD-461. This filter is
intended for applications requiring compatibility to MIL-
STD-704A.
These EMI filters are manufactured in a facility certified
to MIL-PRF-38534 and are available with military
screening. Four grades are offered with different
screening options. Refer to Part Number section.
