Cylindrical Style EMI Filters
GK Series – .375/.410 Dia.
Hermetically Sealed – Circuits Available – C, L, π, T
APPLICATIONS
The GK series offers effective filtering from
30 KHz to 10 GHz. Glass sealed for
hermeticity, this series is impervious to
high moisture, solvents, or other severe
environmental conditions commonly
encountered in military applications. It
is designed for bulkhead mounting in
a slotted hole with nut and lockwasher
supplied.
inductor elements offer increased filter
performance and protection against circuit
transients. Data showing the actual
inductance versus various levels of DC or
AC bias current are available as well as the
attenuation in any combination of source
and load impedances.
Alternate lead configurations or special
capacitance/inductance values may be
ordered.
The “L” and “T” configurations are designed
to provide effective attenuation over a wide
range of circuit impedances. For current
ratings under 10 Amps toroidal wound
Custom packages or filter arrays utilizing
the GK series can be furnished.
