MMU 0102, MMA 0204, and MMB 0207 Precision MELF Resistors

Vishay offers an enhanced resistance range for precision versions of its AEC-Q200-qualified, thin-film MELF resistors in the 0102, 0204, and 0207 case sizes. They are designed to meet the needs of applications with high stability and reliability requirements. The MMU 0102, MMA 0204, and MMB 0207 are available with low TCR down to ± 15 ppm/K, tight tolerances down to ±0.1%, and high resistance values to 10 MΩ. Compared to previous thin-film MELF resistor offerings, these devices provide significantly higher resistance. For example, a device in the 0204 case size with a TCR of ±25 ppm/K and a tolerance of 0.1%, resistance had previously been limited to 511 kΩ. The precision MMA 0204, however, offers 10 times higher resistance of 5.11 MΩ at the same TCR and tolerance and 1 MΩ at an even lower TCR of ±15 ppm/K. With their high resistance, a single MMA 0204 or MMB 0207 resistor can replace multiple lower-value devices used in series, which not only saves space but simplifies designs and lowers overall costs.
