Insights
The enhanced precision thin film MELF resistors represent a significant technical advancement with 10x higher resistance values up to
While this product enhancement strengthens Vishay's position in the precision resistor market, particularly in the growing automotive electronics sector, it's an incremental improvement rather than a market-moving development. The improved specifications and component count reduction could lead to modest cost savings for manufacturers, but the impact on Vishay's revenue is likely to be gradual. The primary value proposition lies in the design optimization benefits for next-generation automotive and industrial applications, though this may take time to materialize in terms of significant market share gains.
Devices Feature Low TCR to ± 15 ppm/K, Tight Tolerances to ± 0.1 %, and High Resistance of Up to 10 MΩ in 0102, 0204, and 0207 Case Sizes
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.
