VPT’s SVCL2800S Series of space qualified inrush current limiters is now DLA qualified after being added to the DLA SMD list, SVCL285R5S and SVCL2811S released on DLA SMD #5962-16216.

The SVCL2800S Series is operable over the full military temperature range (-55 °C to 125 °C) with no power derating. It is designed to control the inrush current drawn by VPT’s EMI filters and DC-DC converters during turn on. The device functions by limiting the rate of rise of its output voltage and controlling the inrush current of discrete input capacitors.

The series is radiation hardened and suited for use in low-Earth orbit (LEO), geostationary orbit (GEO), deep space, and launch vehicle programmes. It has a guaranteed TID performance to 100 krad (Si) including ELDERS and SEE performance to 85 MeV-cm2/mg and is qualified to MIL-PRF-38534 Class H and Class K.
