SA - High Efficiency Chokes

SA Series storage chokes have been designed with Fe-based amorphous alloy which provides high flux density and low core loss which is ideaal for optimizing choke design. Providing exceptional efficiency and field modulation when used as loading coils for interim energy storage with SMPS, the use of amorphous cores gives a highly stable inductance over a wide DC bias current range and high "Q" with operating frequencies to 500kHz.

Features

  • Fe-based amorphous alloy cores
  • Operating frequencies to 500 kHz
  • Small size and high "Q"
  • Highly stable inductance with changing DC bias current
  • Low temperature rise
  • Fully encapsulated styles available meeting class GFK (-40°C to +125°C, humidity class F) per DIN 40040
  • Manufactured in ISO-9001 approved factory

Notes:

  1. The µJoule rating (1/2LI²) is the ability of the inductor to store energy
  2. Inductance measured at 0.10Vrms @ 10kHz without DC Current and 0.25Vrms @ 10kHz with DC Current
  3. On larger units and units wound with finer wire additional mechanical mounting is recommended. See below for Mounting Styles
