RTMSS Cores (Super-MSS)

RTMSS type cores used in DTMSS cores

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

Applications:
  • power transformers (5kHz - 200kHz)
  • interference suppression chokes (DC - 300kHz)
  • energy storage chokes (DC - 300kHz)
  • AC and DC filters
  • flyback transformers
  • automotive ignition systems
  • EMI filters (DC - 1 MHz)

Feryster company is official distributor of Micrometals Alloy Powder Cores. Besides of a MPP and HF core we offer for our customers Super-MSS core samples (see table below). Super-MSS is an improved Sendust material, originally developed by Micrometals Alloy Engineering. It is designed to replace iron powder by offering much lower losses, with energy storage capability higher than MPP. Super-MSS cores are an excellent choice for energy storage and filter inductor applications in Switch Mode Power Supplies. The low loss properties of Super-MSS cores minimizes the temperature rise at power frequencies to well below that of a similar sized iron powder core. The DC Bias characteristics of Super-MSS are also excellent compared to iron powder of similar permeabilities and size.

The table below shows the Super-MSS sample list which Feryster Company has on its stock, in enough quantities for building prototype applications. They are available for all our customers. For all interested in Micrometals Alloy Powder Cores cores, we offer the newest free catalogs. Designers can download Micrometals Alloy Powder Coresoftware dedicated to design inductors based on Micrometals Alloy iron powder cores. See also MPP and HF Micrometals Alloy Powder Cores.
