    Power or High-Frequency Inductors

    Power inductors typically need to support a ripple current AND support a high peak current without saturating. With switch mode power supply frequencies moving upward every year, the demands on inductors are starting to outpace conventional wire-wound technologies. That’s why we maintain an active R and D effort focused on switch mode power supply magnetics. With three patents and 1000’s of power inductors currently in use, we are recognized as an industry leader for best-in-class engineering solutions for this important component.

    750 uH 8 amp Toroidal

    Toroidal: This 1 mH, 8 amp powdered core toroidal inductor is ideal for buck boost applications at power levels up to 10 kW, and frequencies up to 250 kHz. With a soft roll off of L vs. Ipk, very low EMI and low distributed capacitance, this inductor is suitable for applications with up to 10% peak to peak ripple. Different core options and winding options are available depending on the specific design objectives.

    70 uH 220 amp Chassis Mount

    Chassis Mount 75 uH, 220 Amp. Used in a wireless charging system for a zero emission all electric bus, this boost inductor manages 100 kW of high ripple current at 10 kHz. Incorporating WCM’s patented foil technology, this design has low AC loss and low DC resistance and the core has a high Bsat to handle over 200 amps of peak current.

    High Current Inductors (323 Series)

    West Coast Magnetics' 323 series toroidal inductors are designed for switching power applications at frequencies up to 500 kHz This inductor has an outstanding current rating for its size, high reliability, long service life and ability to handle very high peak currents without saturating. The continuous service temperature rating is 200 degrees C.

    Shaped Foil SMD Inductor (308 Series)

    Available with patented Foil Technology for high ripple, high frequency applications.

    West Coast Magnetics' 308 series power inductors deliver very high performance in a small, light, low cost package. They have been designed to handle very high DC currents and high AC ripple currents from 60Hz up to 500kHz.These inductors offer exceptional reliability with an operating temperature rating of 200C and they can be ordered using West Coast Magnetics' SHAPED FOIL TECHNOLOGYTM.

    Shaped Foil Chassis Inductor (307 Series)

    Available with patented Foil Technology for high ripple, high frequency applications.

    West Coast Magnetics' 307 series power inductors offer exceptional performance in a compact package. These inductors can handle very high DC currents and high AC ripple currents from 60 Hz up to 500 kHz. They offer exceptional reliability with an operating temperature rating of 200C and can be ordered using West Coast Magnetics' Shaped Foil TechnologyTM. Our exclusive shaped foil technologyTM combines the low DCR of a foil winding, with the low AC winding resistance of litz wire. For many high ripple, high frequency applications it has significantly lower winding losses than any litz or solid wire winding. Check with WCM's engineering department to see if it is right for your application.

    Custom Resonant Circuit Inductors

    Tuned Air Coil

    Tuned Air Coil:  Used in an RF power delivery system for a medical device, this style of inductor is ideal for RF power applications at frequencies over 5 Mhz.  We can provide this style of inductor pre-tuned at tolerances as tight as 2%, and the inductance is completely stable with power and environmental variances.

    Tunable High Q

    Tunable High Q: This fully tunable 11.5 uH inductor is used in a tuned resonant power delivery circuit at 1.5 Mhz. Featuring very high Q, very low EMI, and stable properties of a wide range of ambient and circuit conditions.

    RF Inductors

    Most of the standard product RF inductors on the market today simply don’t deliver outstanding performance. We know exactly how to nail your Q requirement, and we have extensive experience delivering tuned inductors, at tolerances as tight as 1%. In fact, we recently won an innovative product design award for our 203 series product. Whether your application is delivering power, or used in a signal application we have a proven solution for you.
