USA: AVX Corp. has expanded both its TransGuard and Automotive TransGuard series multilayer varistors to include glass-encapsulated, acid-resistant parts for use in high energy and harsh environment commercial, industrial, and automotive applications.
Exhibiting non-linear, bi-directional, V-I characteristics, both zinc-oxide-based ceramic semiconductor device series provide bi-directional over-voltage protection and EMI/RFI attenuation in a single SMT package. The series also feature multi-strike capability, sub 1nS response to ESD strikes, and excellent solderability.
Ideal for use in harsh environments -- such as those utilizing acid, salt, or chlorite flux -- AVX's glass-encapsulated TransGuard and Automotive TransGuard series varistors are available in three case sizes (1210, 1812, and 2220), four energy ratings (spanning 2-12J) and feature a peak current rating of up to 2000A.
Both series have Ni/Sn-plated terminations, are RoHS compliant, are rated for use in temperatures spanning -55 degrees C to +125 degrees C, and are packaged on 7" or 13" reels.
