HF 270 Series

Distributed Air Gap. High Flux Cores used.
Capable of handling very high DC bias current with minimal inductance roll off.
Best suited for high Power, high AC & DC Bias at high Switching Frequency.
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.


FEATURES:
  • Designed using high saturation (15,000 gauss) 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 3.2 uH to 1000 uH
  • Current rating from 2.1 Amps to 50 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
  • Application: Inductor for switching regulators, In-line noise filters; Flyback Transformers, PFC, Pulse transformer, Output Inductor, energy storage inductor

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.
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
