2025-04-25 power

Riverside, Friday, 25 April 2025.
Bourns introduces the BVRA1210 and BVRA1812 series, automotive-grade varistors engineered for superior surge protection. These components offer quick response times and compliance with rigorous industry standards.

Advanced Technical Specifications

The newly released BVRA series demonstrates impressive technical capabilities, featuring an ultra-fast response time of less than 1.0 nanoseconds and operating across a DC working voltage range from 11V to 100V [1]. These automotive-grade multilayered varistors are available in compact surface-mount designs, specifically EIA 1210 and EIA 1812 formats, making them ideal for space-constrained applications [2]. The announcement, made on April 22, 2025, showcases Bourns’ commitment to advancing automotive electronics protection [3].

Industry Compliance and Safety Standards

Both BVRA1210 and BVRA1812 series meet rigorous industry standards, including AEC-Q200 compliance and IEC 61000-4-5 certification [4]. These varistors are specifically engineered for critical automotive applications, including CAN, LIN, and FLEXRAY based modules, providing essential protection against potentially damaging transient voltage spikes [2]. The components are manufactured under strict quality controls, adhering to ISO-9000 standards and Six Sigma quality programs [5].

Market Implementation and Applications

The BVRA series addresses crucial protection needs in automotive power supplies, entertainment electronics, and circuit board level protection against transient events [2]. These components arrive at a critical time when the automotive industry is rapidly advancing toward electrification, which has been identified as a key component in achieving climate-neutral goals globally [6]. The series offers excellent transient energy absorption capabilities through improved energy volume distribution and power dissipation, making them particularly valuable for modern automotive electronic systems [2].
