Soft Termination Varistor Resistant to Substrate Deflection

Introducing FLEXITERM^®, a soft termination varistor with improved resistance to substrate deflection. It is especially suitable for in-vehicle applications.

FLEXITERM^® is a registered trademark of KYOCERA AVX Components Corporation.

Overview

KYOCERA AVX offers varistors that are designed to prevent static and surge damage, making them a reliable choice for industrial applications. Among these is FLEXITERM^®, a soft termination varistor with enhanced resistance to substrate deflection, a crucial specification for automotive applications.

FLEXITERM^® by KYOCERA AVX utilizes conductive resin for the electrodes, providing tolerance to deflection of up to 5mm. In comparison, conventional varistors offer 2mm of resistance. It is particularly well-suited for applications that demand high reliability and safety, such as direct battery connection lines for automotive equipment.

Features

Performance of 3000 cycles of temperature cycling test
Lineup of products with maximum operating temperature of 125°C and 150°C
Compliant with AEC-Q200.
Size: 1.6x0.8 / 2.0x1.2 / 3.2x1.6 / 3.2x2.5mm

Substrate Deflection Test

Test Method

For each varistor mounted on the board, bend the substrate until the varistor fails.

Test Result

The soft termination product （FLEXITERM^®） has significantly improved resistance to substrate deflection compared to general varistors.
