DC FILTERS
General Purpose
FD Series Filters
The FD Series of DC filters are designed as a general
purpose line of filters for DC applications. They are
designed to comply with UL/EN 60950 and UL 1459,
CISPER 22 and Telecordia (Bellcore) GR-1089 at
25Amps and above. These filters are available with and
without circuit breakers for additional protection.
The FD Series is a compact size that can filter up to
300MHz ideally suited for the telecom-datacom market.
The FD0 Series is available from 6Amps to 100Amps in
the smallest, economical package. The FD02 is a high
frequency filter up to 3GHz (3,000MHz) in a compact
package.
These filters are ideally used in communications and
central office equipment.
