10-32 Thread

Bolt Style EMI Filters
SH Series – 10-32 Thread - Epoxy Sealed –
Circuits Available – C, L, π
APPLICATIONS
The SH series provides intermediate
filtering in the RF through MICROWAVE
frequency spectrums from 100 KHz
through 10 GHz. The larger hex size
means that much higher values of capacitance are available in the feedthru style
circuits and that a 125 VAC/400 Hz rating
is available in certain values. Also
designed for mounting in a tapped bulkhead or with the standard nut and lockwasher provided, it is optimum in medium
to low impedance circuits where significant
amounts of capacitance to ground can
be tolerated. In the “L” and “π” section
versions an internal ferrite bead element
provides both inductance and series
resistance (lossy characteristic) which
improves the insertion loss rolloff to 40 dB
and 60 dB per decade respectively.
Alternate lead diameters or lengths are
available, both with and without a nailhead.
CHARACTERISTICS
• Equivalent to SB series π circuits and to
SP series feedthru or “L” circuits.
• Conservatively rated for 125 VAC/400
Hz in certain values.
•
π
design offers steeper insertion loss
rolloff.
• Features rugged monolithic discoidal
capacitor construction.
• Epoxy seal on both ends.

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

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