Improved Thin Film Resistors For Lighting/Industrial/Automotive Usecases

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

The improved 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.

Using advanced metal film technology, the devices now 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.

Furthermore, the resistors, available in 0102, 0204, and 0207 case sizes, are said to 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”, according to the firm.

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

Samples and production quantities of the MMU 0102, MMA 0204, and MMB 0207 are available now, with lead times of six to eight weeks for larger orders.
