Cylindrical Style EMI Filters
BK Series – .375/.410 Dia. – Button Hermetically Sealed
Circuits Available – C & L
APPLICATIONS
The BK series offers effective filtering
from 500 KHz to 10 GHz. Glass sealed
for hermeticity, this low profile series is
impervious to high moisture, solvents, or
other severe environmental conditions
commonly encountered in military appli-
cations. 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 pro-
vides superior transient performance.
Alternate lead configurations or special
capacitance values may be ordered.
Custom packages or filter arrays utilizing
the BK series can be furnished.
CHARACTERISTICS
• .410 Dia. version (AK) meets or exceeds
the applicable requirements of MIL-F-
28861/1. See QPL listings.
• Internal ferrite bead provides inductance
for the L-section version.
• High DC current rating: 15 Amps
• Glass hermetic seal on both ends.

Non-decimal point values indicate capacitance in picofarads.
2 Insertion loss limits are based on theoretical values.
Actual measurements may vary due to internal capacitor
resonances and other design constraints.
