Module Defends Against EMI And Transients

Wearing two hats, the VPTc10-28 combines an EMI filter and voltage transient protection in one module with built-in reverse polarity protection. Teaming with the company’s DV and VPT series isolated dc/dc converters, the module provides compliance for both ISO 7637-2 and DEF STAN 61-5 Part 6 Issue 6 input power requirements for vehicle systems and other apps. Additionally, it reduces reflected noise from the converters to meet DEF STAN 59-411 Part 3 Issue 1 requirements for conducted emissions. Other features include a wide input voltage range, transient operation up to 202V, 45-dB minimum attenuation at 500 kHz, inrush current limiting, true reverse polarity protection, operating temperature range of -55°C to +100°C, and a rugged, six-sided metal enclosure.
