Luso Electronics stocking SynQor Mil-COTS transient filters

Luso Electronics Distribution, the UK and Ireland representative for the SynQor range of power supplies and related components, is now stocking a new line of Mil-COTS (Military – Commercial-Off-The-Shelf) of half-brick transient EMI filters.

Designed and manufactured to comply with a wide range of military standards, the filters also meet the requirements of DEF STAN 61-5 Part 6 Issue 6, which deals with 12V vehicle systems as well as the 24/28V systems commonly used in military vehicles and enables engineers to develop standard products that meet the requirements of both architectures.

In addition, SynQor’s innovative packaging ensures survivability in hostile environments. Compatible with the industry-standard format, the filters have high differential-mode and common-mode attenuation, low DC resistance, and a stabilizing bulk capacitor resistor. The filters, when combined with Mil-COTS DC-DC converters, are designed to comply with MIL-STD-704, MIL-STD-1275, RTCA/DO-160, DEF-STAN 61-5 and MIL-STD-461 for a 28V system.

Rated to handle 30A output current, electrical characteristics of the family include –40 to +40V input voltage; very low DC resistance; and greater than 80dB differential-mode attenuation and 36dB common-mode attenuation at 250kHz.

Other features of the device include transient-suppression circuitry to block voltage surges and spikes; soft-start circuitry to limit in-rush charging currents; reverse polarity protection with a low-loss synchronous rectifier; output power limit for short-circuit protection; on/off pass-through circuitry; and standby circuitry to minimize quiescent power draw.

The transient EMI filter units are now available for purchase from Luso for evaluation and qualification.
