KYOCERA AVX Debuts Advanced Multilayer Varistors Tailored for Automotive Electronic Uses
KYOCERA AVX Expands TransGuard Automotive Series with Advanced High-Current Load Dump Varistors
KYOCERA AVX, has expanded its TransGuard Automotive Series with the introduction of a new class of high-current load dump varistors, continuing its more than twenty-year legacy of delivering dependable bidirectional overvoltage protection along with EMI/RFI attenuation. This latest innovation represents a notable leap forward in the realm of automotive circuit safeguarding.
Building on the reputable TransGuard Automotive Series, the newly released load dump varistors are engineered from zinc-oxide-based ceramic semi-conductor materials encased in a compact SMT housing. Complying with AEC-Q200 standards, they provide superior defense against voltage spikes from various disturbances, such as ESD, induction motor loads, and module load dumps.
The innovative varistors of the TransGuard Automotive Series bring to the table a monolithic multilayer structure, bidirectional nonlinear voltage-current relationship, robust current and energy absorption capabilities, resilience to multiple strikes, and swift response times below one nanosecond. Selected models are further equipped with glass encapsulation to withstand environmental contaminants, including acids, salts, and chlorite flux..
BonChip Electronics, a trusted distributor of the entire KYOCERA AVX product line, offers the complete portfolio of TransGuard Automotive Series varistors alongside a wide range of passive components and expert technical support.
