1. Product Introduction

Yageo is one of the world's leading manufacturers of passive electronic components, supplying chip resistors, capacitors, RF components and other products. Its product lines cover consumer electronics, automotive electronics, industrial automation, new energy, communication and other fields. The AC series is Yageo’s dedicated AEC-Q200 automotive-grade anti-sulfur thick film chip resistor series, developed for harsh environments with sulfur gas, moisture and extreme temperature. It is a mainstream choice for high-reliability circuits in automotive and industrial applications.

AC1206FR-07931RL is a 1206 package automotive-grade anti-sulfur thick film chip resistor of the AC series, with a nominal resistance of 930Ω and tolerance of ±1%. It is designed for circuits requiring anti-sulfur performance and wide-temperature stability. It is mainly used for voltage division, current sensing, reference current limiting and signal conditioning, replacing ordinary commercial resistors to avoid failures such as sulfur-induced open circuit and excessive temperature drift. Users can obtain samples and check real-time inventory of AC1206FR-07931RL through SMCC, an authorized distributor of Yageo, to ensure stable supply for R&D and mass production.
