8-32 Thread

Bolt Style EMI Filters
SB Series – 8-32 Thread - Epoxy Sealed –
Circuits Available – C, L, π
APPLICATIONS
The SB series provides improved filtering
in the HF through MICROWAVE frequency
spectrums from 1 MHz through 10 GHz.
Also designed for mounting in a tapped
bulkhead or with the standard nut and
lockwasher provided, it is ideal for medium
to high impedance circuits where large
capacitance values are not practical.
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.
CHARACTERISTICS
• Designed to meet or exceed the applicable portions of MIL-F-28861/7. See QPL
listings.
• π design offers steeper insertion loss
rolloff.
SPECIFICATIONS
1. Plating: Silver standard – Electro-tin or
gold available
2. Material:
Case: Cold rolled steel
Leads: Half/hard copper
3. Operating Temperature Range:
-55°C to +125°C
4. Insulation Resistance:
At 25°C: 1,000 megohm-microfarad
min., or 100,000 megohms
min., whichever is less
At 125°C: 100 megohm-microfarad
min., or 10,000 megohms
min., whichever is less
5. Dielectric Withstanding Voltage (DWV):
R-level designs:
2.0 times rated DC voltage
Class B, Class S designs:
2.5 times rated DC voltage
6. DC Resistance (DCR): .01 ohm,
maximum
7. Dissipation Factor (DF): 3% maximum
8. Rated DC Current: 10 Amps, maximum
9. Recommended Mounting Torque:
64 oz-in. ± 4 oz-in.
10. Supplied with mounting nut and lockwasher - See Filter Design Guide Screw
and Locking Washer Table
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.
• Features rugged monolithic discoidal
capacitor construction.
• Epoxy seal on both ends.

Decimal point values indicate capacitance in microfarads.
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.
