Vishay IGBR Thin Film Resistors

Introduction

Vishay / Thin Film IGBR thin film resistors are compact, high-power resistors developed for demanding power-electronics assemblies. Qualified to AEC-Q200 requirements, these resistors are intended for high-reliability applications where thermal performance, small size, and stable resistance are important.

Part Description

The IGBR series consists of back-contact thin film resistors designed for integration into SiC, GaN, and IGBT power modules. Their back-contact construction can support efficient thermal coupling to the mounting surface, helping the resistor manage high power levels despite its miniature package size.

These resistors are rated for operation at temperatures up to 200°C, making them suitable for high-temperature power conversion environments. Multiple attachment approaches are available, including sintering, soldering, and epoxy bonding, allowing designers to select an assembly method that matches their module construction and manufacturing process.

Key characteristics include:

• AEC-Q200 qualification for automotive-grade passive component requirements
• High power capability in compact case sizes
• Thin film resistor technology
• Back-contact configuration
• Compatibility with SiC, GaN, and IGBT power modules
• Operating temperature capability up to 200°C
• Sintering, soldering, or epoxy attachment options
