Vishay Beyschlag Chip Resistors in 0402 Package Feature TCR Ratings from ±25 ppm/K to ±10 ppm/K and Resistance Values from 100 Ohms to 221 kilohms

MALVERN, PENNSYLVANIA - January 21, 2005 - Vishay Intertechnology, Inc. (NYSE: VSH) has announced that it has extended its family of Vishay Beyschlag thin film flat chip resistors with the introduction of high-stability, precision devices in miniature 0402 packages. Available with values from 100 Ω to 221 kΩ, the new devices offer the industry’s widest resistance range for CECC-certified precision resistors at this size.

All of the devices in the new MCS0402 range are qualified according to EN 140401-801. Precision characteristics include close tolerances of ±0.1 % or ±0.25 %, superior overall stability (class 0.1 and 0.25), and TCR ratings from ±25 ppm/K down to just ±10 ppm/K.

The combination of small size and precise, stable operation makes the MCS0402 resistors ideal for high-accuracy designs where board space is limited. As a result, potential applications include telecom base stations, cellular handsets, test and measurement equipment, industrial systems, and consumer electronics products including high-end audio technology. The devices are also suitable for medical equipment and automotive electronics applications such as body electronics, security, engine management, and power supplies.

MCS0402 precision resistors have a maximum voltage rating of 50 V and are designed to operate with film temperatures up to 125 °C. Rated power dissipation is specified at 0.063 W, while insulation voltage is rated at 75 V (for one minute continuous).

The superior precision and stability characteristics of the Vishay Beyschlag MCS0402 series have been achieved by combining an ultra-stable thin film resistive layer, high-quality contacts between the resistive and conductive layers, and an advanced, proprietary laser trimming method that ensures maximum accuracy.

The MCS0402 ultra-small thin film precision resistors join the Vishay Beyschlag existing ranges of surface-mount precision resistors, which include devices in 0603 outline offering resistance values from 39 Ω to 511 kΩ, 0805 devices with values from 39 Ω to 1.5 MΩ, and 1206 devices rated from 39 Ω to 2 MΩ.

Vishay Beyschlag MCS0402 resistors are fully compatible with tin-lead and lead (Pb)-free soldering processes.
