MMU 0102, MMA 0204 and MMB 0207 precision thin film melf resistors combine the proven reliability of the professional products with an advanced level of precision and stability. Therefore they are perfectly suited for applications in the fields of test and measuring equipment along with industrial and medical electronics.
The MMU 0102, MMA 0204 and MMB 0207 series are precision thin‑film MELF resistors offered by Vishay. They are approved to EN 140401‑803 and are intended for test and measuring equipment, industrial and medical electronics. The resistors are RoHS‑compliant and available in lead‑free soldering processes.
Key features include advanced thin‑film technology, Class 0.05 stability, a wide resistance range (10 Ω‑1 MΩ), tight tolerance options (±0.5 % to ±0.1 %), and robust temperature‑coefficient grades (±25 ppm/K to ±15 ppm/K). The devices meet multiple IEC and EN environmental and reliability tests and are supplied in blister tape, reel or bulk case packaging.
