  • HF Series
    (1.4 Amps to 25 Amps)

    High Flux Cores used.
    Capable of handling very high DC bias current with minimal inductance roll off.
    Through hole mount with pre-tinned leads that can be directly soldered to PCB
    Normally our customer specify the specs ( size, inductance, current)and we built to meet the specs.
    Also available in MPP, Sendust/KoolMu cores.

    HF Series High Flux Toroidal Power Inductors.
    Through Hole Mounting Construction



    FEATURES:
    • Designed using high saturation and high temperature stability "High Flux Cores" with distributed air-gap
    • Excellent electromagnetic shielding due to toroidal design
    • Designed for commercial, industrial and military application
    • Low cost designs with pre-tinned leads for PCB through hole mounting
    • Inductance values from 1.5 uH to 330 uH
    • Current rating from 1.4 Amps to 25 Amps
    • Temperature Rating: -55 deg C to +125 Deg C
    • Potted version available for military application
    • Custom designs are available to meet your specific requirements

    Notes:
    1
    ) The prices shown below are for low volume quantity. Please call 800-377-3244 or
    email sales@coilws.com for larger volume OEM pricing.
    2
    ) Our large OEM pricing is extremely competitive. We will meet or beat any competitors prices with better deliveries

    4
    ) The data shown below can be sorted by clicking each column header.Click once again to sort in reverse order.
    5) "Inductance at 1 Khz" ( 2nd column from left in table below ) is the inductance measured at zero or very low DC bias current.
    6) "Current Rating" ( 3rd column from left in table below ) is based on a 40 deg C temperature rise at an ambient temperature of 90 deg C. This is the DC bias current through the inductor that will cause the inductor will reach a max. temp. rise of 40 deg C. above ambient with NO AIR FLOW.
    7) "Incremental Current for 20% inductance drop" ( 4th column from left in table below ) is the DC bias current that will cause the inductance to drop by 20% from the value shown in Inductance at 1 Khz. At this current, the temperature rise may be above the 40 deg C stated above, so forced air flow may be required.
    8) The saturation current is at least 5 times the max current listed in 5) or 6) above, so instantaneous high current spikes can be tolerated by these inductors.
    9) "Dimensions:"

    • A = Outer Dimension
    • B = Height
    • C = Vertical Mounting Hole Distance
    • D = Lead length
    • E = Lead Width
