Radial leaded power line chokes

Download Datasheet



The RL-1256 Series of Power Line Chokes is available in 367 standard values covering a wide range of inductance and current. High saturation flux density material is ideal for use in switching regulated power supply applications. Ideal wherever high current choke values in a small physical size are needed.

Typical Applications

  • Speaker Crossover Networks
  • Power Amplifiers
  • Power Supplies
  • Filters
  • SCR and Triac Controls
