Hammond's 195G20 is a heavy-current choke specifically engineered for demanding power supply filtering applications. Its open core and coil design, combined with a 15% tolerance on both inductance and resistance, ensures reliable performance in high-current environments. The choke's robust construction and screw terminal or heavy copper tab connections make it suitable for industrial and commercial use. Recommended for use with a maximum operating voltage of 600 VAC (winding to core), and tested at 2,500 VAC for insulation integrity.
