VPT’s SVCL2800S Series of space-qualified inrush current limiters have been awarded a DLA certificate, with 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. It functions by limiting the rising rate of its output voltage and also controls 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.
