MHF Series
Toroid Chokes

High Flux Cores used.
Capable of handling very high DC bias current with minimal inductance roll off.
Bobbin 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.
Inductance range from: 10 uH to 100 uH
Current range to 1.7 Amps to 15 Amps

Also available in MPP, Sendust/KoolMu cores. See below
Custom designs available

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
3
) Custom designs are available to meet any of your requirements. Please contact us
4
) The data shown below can be sorted by clicking each column header.Click once again to sort in reverse order.
6) "Inductance at 1 Khz" ( 2nd column from left in table below ) is the inductance measured at zero or very low DC bias current.
7) "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.
8) "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.
9) 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.
