DTMSS type choke on RTMSS type core

Energy storage and interference suppressing chokes in SMPS power supplies, wound on RTMSS type toroidal cores

Chokes designed with the intention to replace DTP chokes in applications used within the frequency range of 25kHz - 500kHz with high stability of operating parameters maintained. The main advantages of DTMSS chokes include up to tenfold reduction of losses in the core and up to five times higher limit frequency with respect to metal-powder core chokes. These chokes offer lower losses and lower operating temperature. Therefore, it is possible to achieve more power using the same size choke or reduce the size of the converter (now operating at a higher frequency.)

Applications:

  • interference suppressing chokes (DC - 300kHz)
  • energy storage chokes (DC - 300kHz)
  • DC/DC conventers
  • SMPS
  • EMI filters (DC - 1 MHz)
  • acoustic filters

The available casings or bases are in V and H versions.
