Automotive Ferrites


Vehicle Components Calibrated for Success

Automotive electronics become increasingly advanced and computerized year after year, with multiple systems communicating and operating in close proximity to each another.  As consumer standards rise, multiple wireless devices within the vehicle operate at higher frequencies, leading to EMI and high temperatures.  Our wide range of ferrite chokes, rods, and plates are built to withstand these high temperatures and surpass the rigorous standards set by the automotive industry.  We are a leader in providing solutions to major automotive companies for RFID coils for keyless entry, EMI suppression for spark ignition coils, Can-bus systems, AC to DC power conversion, airbag connectors and more. 

Benefits of Our Automotive Ferrites

Constructed from ultra-thin mixtures of iron, nickel and zinc oxides, our automotive ferrites are characterized by their size, light weight, low cost, and high reliability.  They provide superb EMI reduction while remaining open to normal circuit operation.  Other benefits include:

  • Multiple sizes, materials, and customization available
  • Slotted or notched ends possible
  • Accurate current matching capability over a broad range of inductance values
  • Low distortion
  • Sector wound coils at 25 & 51Hz to filter differential mode noise from the data signal
  • Surface mount
  • Open bottom case construction available
