Vishay Intertechnology, Inc. (NYSE:VSH) today introduced new high-voltage professional thin film MELF resistors in the 0204 and 0207 case sizes. Designed for industrial, lighting, and medical applications with high stability and reliability requirements, the Vishay Beyschlag MMA 0204 HV and MMB 0207 HV resistors combine a robust construction with industry-high operating voltages to 1000 V.

Built on an advanced metal film technology, the devices released today provide proven reliability for high-voltage electronic circuits in lighting ballasts and LED drivers, industrial inverters and converters, battery management systems, and medical equipment. In these applications, the resistors save board space and simplify designs by replacing devices in larger case sizes, multiple resistors in similar case sizes, and leaded resistors.

The MMA 0204 HV and MMB 0207 HV offer a resistance range from 340 k to 10 M with tolerance of +/- 1 %, TCR of +/- 50 ppm/K, rated power dissipation to 1.0 W at +70 oC, and excellent long-term stability down to < 0.5 % after 1,000 hours. Suitable for processing on automatic SMD assembly systems, the lead (Pb)-free devices are RoHS-compliant, halogen-free, and Vishay Green.

Device Specification Table:

Case size 0204 0207
Resistance range 340 k to 10 M
TCR +/- 50 ppm/K
Tolerance +/- 1 %
Rated Dissipation P70 0.4 W 1.0 W
Operating voltage 500 V 1000 V
