Used on its own to suppress noise in radios, and other electronic equipment on vehicles. When used inline with a Translectric DC-DC converter, it provides voltage spike protection for the converter. ROHS (reduction of hazardous substances) is becoming a big issue. Already in Europe, many electronic devices are required to be manufactured with lead-free components and solder. In an effort to stay on the cutting edge, Translectric has already made this move. Each converter produced by Translectric uses lead-free components, and lead-free solder. As added insurance, all electronic components are completely encapsulated in epoxy. This provides waterproofing, shock resistance, and ROHS compliance. Features: Metal oxide varister clamp for max voltage surge High efficiency Low dc circuit impedance 20 A continuous output current LCR low pass tuned circuit Shielded against noise and RF interference
