Inductors

Group of inductors

Quality Engineered for Performance and Reliability

  • Common Mode Chokes
    Attenuation of common mode line noise in switching power supplies. High attenuation over a wide frequency range, available in a wide range of inductances and current ratings. Windings balanced within one percent. Dielectric strength to requirements.

  • Input / Output Chokes
    Wide range of core styles (toroidal, EE, EI, UI, UU, EP, EFD, RM, PQ, ETD, ER, etc). Inductance range, current range & energy storage range to suit. SMT and THT mounts and DC bias current capability.

  • Air Core Inductors
    Able to handle high currents, no saturation. Wide range of inductance values. Inside Diameter from 0.060" to 6". High Linearity, Very High Q
    THT & SMT mounting.

  • Custom & Equivalents
    Effective designs for a wide range of inductors to suit your specific applications. Providing you with the performance, workmanship and reliability that you need.
  • Encapsulated Inductors

    Epoxy or Silicone Encapsulation provides protection from harmful environments such as shock, vibration, moisture and corrosive agents; improved thermal transfer; and vacuum processing of high dielectric strength materials for high voltage applications.

    Other inductors we supply include Power Factor Correction Inductors, DC Inductors, Filter Chokes, High Current Inductors and SMPS Inductors.
