Hammond 195P5 30mH 5A Single-Coil Heavy Current Filter Choke

The 195P5 is a single-coil heavy current chassis mount choke rated 30 mH at 5 A DC. It suits designers building DC power supplies that need meaningful inductance at a moderate current in a compact footprint.

Built as an open core and coil assembly with 4-slot bracket mounting, the 195P5 has a listed winding resistance of 0.23 ohms and Class A insulation. The series ordering table gives dimensions A 3.75 in (95 mm), B 4.20 in (107 mm), C 3.13 in (80 mm), D 3.13 in (80 mm) and E 2.75 in (70 mm), with 0.20 x 0.38 in (5 x 10 mm) mounting slots.

The series table weight is 6.5 lbs, while the part page shipping weight is 5.9 lbs (2.68 kg). Within the 30 mH group, this is the lowest-current model, sitting below the 195P8, 195P10 and 195P20.

Across the 195-196 Series, inductance and resistance are held to a 15% tolerance, inductance is measured at rated D.C. current, and connections are made to a screw terminal or heavy copper tabs with holes. The series is rated for operation from -40C to 85C and storage from -40C to 105C, with a recommended maximum operating voltage of 600 VAC winding to core. Chokes in the series are hipot tested at 2,500 VAC. The chokes are UL approved under Type 3AH, E207860, 30V7, and this part is listed as RoHS and REACH compliant.
