Common Mode Choke Coils

Part Number Information
Part #: Price/Availability:

Murata Americas' PLT5BPH Series of common mode choke coils, developed for automotive noise suppression applications, is capable of handling large currents (up to 5.6A) and wide operating temperature range (-55°C to 150°C). Automotive design engineers are placing a great deal of importance on improving efficiency and the ability to withstand severe environments. To achieve more precise control, many engineers are positioning electronic components closer to the engine or transmission in denser circuits. 


  • The PLT5BPH Series is available in a small case size, measuring just 5.0 × 5.0mm (.20 x .20 in) 
  • Usable temperature range of -55°C to +150°C 
  • Common mode impedance up to 500Ω (at 10MHz), substantial common mode (as well as normal mode) noise suppression 
  • Generates maximum 500Ω common mode impedance (at 10MHz), for substantial noise suppression 
  • Differential mode impedance is high in addition to common mode impedance, enabling substantial suppression of normal mode noise 
  • The PLT5BPH Series is AEC-Q200 compliant.
