Vishay Intertechnology introduces enhanced precision MELF resistors with higher resistance, low TCR, and tight tolerances for reliable applications.
Quiver AI Summary
Vishay Intertechnology, Inc. has announced an expanded resistance range for its precision AEC-Q200 qualified thin film MELF resistors in case sizes 0102, 0204, and 0207. The new models, MMU 0102, MMA 0204, and MMB 0207, feature low temperature coefficients of resistance (TCR) down to ±15 ppm/K and tolerances as tight as ±0.1%, with resistance values reaching up to 10 MΩ. This significantly increases the resistance capability compared to previous versions, allowing for a single resistor to replace multiple lower-value resistors, which simplifies designs, saves space, and reduces costs. The resistors are designed for high stability and reliability, making them suitable for automotive and industrial applications, and are compliant with RoHS and halogen-free standards. Samples and production are available now with a lead time of 12 weeks.

Full Release
MALVERN, Pa., Dec. 18, 2024 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced an enhanced resistance range for precision versions of its AEC-Q200 qualified thin film MELF resistors in the 0102, 0204, and 0207 case sizes. Designed to meet the needs of applications with high stability and reliability requirements, the Vishay Beyschlag MMU 0102, MMA 0204, and MMB 0207 are now available with low TCR down to ± 15 ppm/K, tight tolerances down to ± 0.1 %, and high resistance values of up to 10 MΩ.
Compared to previous thin film MELF resistor offerings, the devices released today provide significantly higher resistance. For example, for 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, now 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 its high resistance, a single MMA 0204 or MMB 0207 resistor can replace multiple lower-value devices used in series, which not only saves spaces but also simplifies designs and lowers overall costs.
Built on an advanced metal film technology, the precision resistors provide proven reliability for current sensing in power supplies for automotive ADAS, LIDAR, connectivity, and camera systems, in addition to telecom, industrial, and medical equipment. For these applications, the devices feature a robust design, intrinsic sulfur resistance, and excellent overall stability that exceeds stability class 0.05. Suitable for processing on automatic SMD assembly systems, the lead (Pb)-free resistors are RoHS-compliant, halogen-free, and Vishay Green .
