Devices Feature Extended Resistance to
Lower Ohmic Values < 1 Ω, Tighter Tolerance, and Low
Temperature Coefficient
Vishay Intertechnology, Inc. (NYSE:VSH) today announced that it has
extended 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. 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.
Built on an advanced metal film technology, the
devices released today 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.
Suitable for processing on automatic SMD assembly
systems, the lead (Pb)-free devices are RoHS-compliant,
halogen-free, and Vishay Green.
