Thin film MELF resistors down to 0.22 Ohm

October 06, 2016 // By Julien Happich
Vishay Intertechnology's range of AEC-Q200-qualified professional Thin Film MELF resistors has been extended to tighter tolerances in the low-ohmic range below 1 Ω for the 0204 and 0207 case sizes.

In addition to providing a low temperature coefficient, the improved Vishay Beyschlag MMA 0204 and MMB 0207 allow for more precise current measurement in LED lighting, industrial, automotive, and renewable energy applications with high stability and reliability requirements than previous-generation devices. Designed for operation in the -55 to +155ºC temperature range, the devices offer an extended resistance range down to 0.22 Ω with tolerance of ± 1 %, low TCR of ± 50 ppm/K, and rated power dissipation to 1 W at +70°C. The professional thin film MELF resistors, available in 0102, 0204, and 0207 case sizes, feature a robust design, intrinsic sulfur resistance, and excellent overall stability that exceeds class 0.25. Suitable for processing on automatic SMD assembly systems, the lead (Pb)-free devices are RoHS-compliant, halogen-free, and Vishay Green.
