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.

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.
