Cylindrical Style EMI Filters

Cylindrical Style EMI Filters
CK Series – .375 Dia. – Button Hermetically Sealed –
Circuits Available – C & L
APPLICATIONS
The CK series offers effective filtering
from 100 KHz to 10 GHz. Glass sealed
for hermeticity, this medium profile 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. This series is ideal
for low to medium impedance circuits
where large amounts of capacitance to
ground can be tolerated. In the “L”
section version an internal ferrite bead
element provides both inductance and
series resistance (lossy characteristic)
which improves insertion loss and provides superior transient performance.
Alternate lead configurations or special
capacitance values may be ordered.
Custom packages or filter arrays utilizing
the CK series can be furnished.
