Combining circuit protection and EMI/RFI attenuation functions in a single, high-reliability device available in two compact sizes, the new high temperature TransGuard Automotive Series varistors provide bidirectional transient voltage protection in the on-state and EMI/RFI attenuation in the off-state, effectively reducing component count and saving critical board space.
According to the vendor, the series features the smallest varistors available on the market in addition to the highest temperature ratings in the industry. Exhibiting excellent current and energy handling capabilities, the new high temperature varistors are available in four working voltages (14, 18, 26, and 48V), four clamping voltages (60, 67, 100, and 150V), and three energy ratings (0.1, 0.4, and 2.0J), and are also rated for 25kV ESD. Conformally coated with epoxy resin for enhanced durability in harsh environments, the lead-free and RoHS-compliant series is available in two sizes and with Ni underplate/100% Sn plated wire leads. Nickel-free leads are available upon request.
