Solder-In Style High Temp EMI Filters
YS/YR Series – .165 Dia. – Circuits Available – C & L
APPLICATIONS
The YS series provides increased filtering
in the MICROWAVE frequency spectrum
from 1 MHz through 10 GHz. Previously
unavailable in the industry as a solder-in
device, this unique design offers higher
values of capacitance than were previ-
ously available. Designed to be soldered
into a package, bracket or bulkhead (and
maintain hermeticity), it is ideal for high
impedance circuits where large capaci-
tance values are not practical. 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 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-28861/15. 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.
