The 159ZL is an economical, open-bracket DC filter choke designed for power supply filtering. It provides a nominal inductance of 2.5mH at a rated DC current of 10A and features a low DC resistance of 47mOhm. Key electrical characteristics include a dielectric strength of 2500V RMS, a self-resonant frequency of 768 KHz, and a maximum operating temperature of 105°C. Impregnated with polyurethane varnish for quiet operation and long life, its channel-mount design is ideal for high-voltage power supply filtering circuits.
