Solder-In Style High Temp EMI Filters
ZS/ZR Series – .128 Dia. – Circuits Available – C & L
APPLICATIONS
The ZS series provides effective filtering
in the MICROWAVE frequency spectrum
from 10 MHz through 26 GHz. Designed
to be soldered into a package, bracket or
bulkhead (and maintain hermeticity), it is
ideal for high impedance circuits where
large capacitance values are not practical.
In the “L” section version an internal fer-
rite bead element provides both induc-
tance and series resistance (lossy charac-
teristic) which improves insertion loss and
provides superior transient performance.
Alternate lead lengths or special capaci-
tance values may be ordered.
Custom packages or bracket assemblies
utilizing this feedthru can be furnished to
your specifications.
CHARACTERISTICS
• Meets or exceeds the applicable portions
of MIL-F-28861/12. See QPL listings.
• Glass hermetic seal on one end with
epoxy seal on the opposite end.
• High temperature construction with-
stands 300°C installation temperatures.
• High purity gold plating provides excel-
lent solderability or compatibility with
thermal and ultrasonic wire bonding.
• Features rugged monolithic discoidal
capacitor construction.

11. Insertion Loss for the “C” and “L” circuits
are equivalent due to the saturation
characteristic of the ferrite bead element
at full rated current. At lower currents the
“L” becomes much more effective.
