Vishay’s New Professional Thin Film MELF Resistors Ideal for Precise Current Measurement in Lighting, Industrial, and Automotive Applications


Vishay Intertechnology announces extension of its AEC-Q200-qualified Professional Thin Film MELF resistors to tighter tolerance in the low-ohmic range below 1 Ω for the 0204 and 0207 case sizes.

Built on an advanced metal film technology, 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.
  • The MMU 0102, MMA 0204, and MMB 0207 provide proven reliability for current sensing in DC/DC conversion and pulse-width modulation in LED drivers, solar inverters, industrial electronics, and battery management systems for electric and hybrid vehicles, in addition to telecom and medical equipment.
  • The devices are backed by Vishay’s more than 30 years of experience developing thin film MELF resistors.

Applications include

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.

Suitable for processing on automatic SMD assembly systems, the lead (Pb)-free devices are RoHS-compliant, halogen-free, and Vishay Green.
