AVX extends its compact, radial leaded, high temperature Transguard Automotive Series

AVX Corporation has added several new high temperature varistors to its radial leaded TransGuard Automotive Series. Based on the company’s patented multilayer varistor (MLV) technology, the new components are rated for -55°C to +150°C, qualified to AEC-Q200, and feature a robust construction that enables sustained peak performance in an expanded range of harsh environment and high temperature applications, such as under hood and down hole drilling.

By 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 are able to 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.

“AVX’s radial leaded, high temperature TransGuard Automotive Series features the smallest varistors available on the market in addition to the highest temperature ratings in the industry. Extremely compact with regard to height, width, and thickness despite their dual circuit protection and EMI/RFI attenuation functionality, the series provides designer engineers with a highly reliable, single component solution that’s more conducive to creating space-saving designs than leaded disc varistors,” said Jiri Machanicek, Technical Marketing Manager at AVX.

Exhibiting improved current and energy handling capabilities, the new high temperature TransGuard Automotive Series 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.
