The 159V is a surface-mount low to medium current DC reactor or filter choke. It features a 15% tolerance on both inductance and resistance and is designed to exhibit slightly varying inductance depending on the current load—less at higher currents and more at lower currents. The unit is vacuum impregnated with polyurethane varnish, ensuring quiet operation and long service life. It is suitable for high-voltage power supply filtering applications and is commonly used in industrial, automation, and process control systems. The leads are at least 5 inches long for easy installation.
