Vishay Intertechnology Releases New Thin Film Resistor Networks, Precision Matched-Pair Resistors, and Optocouplers
MALVERN, PA. Vishay Intertechnology, Inc. (NYSE: VSH), has announced the release of new surface-mount thin film resistor networks, precision matched-pair resistors, and optocouplers.
The three series of thin film resistor networks combine up to 23 resistors in a single, surface-mount package. The new devices will serve in a variety of pull-up and pull-down applications for both analog and digital circuits in industrial, medical, communications, and computing systems. With a temperature coefficient ratio of plus/minus 100 ppm/degrees C and standard tolerances of plus/minus 5%, the resistor networks offer designers a choice of package styles, schematic options, and standard resistance values. Package types include the 16-, 20-, and 24-pin TSSOP (VTSR), SSOP, and QSOP (VSSR), and the 16-pin narrow-body SOIC (VSOR).
The new series of precision matched-pair resistors (thin film resistor dividers) in the surface-mount SOT-23 package features temperature coefficient ratio tracking of plus/minus 2 ppm/degrees C and a ratio tolerance as tight as 0.05%. The new MPM series will serve a wide range of applications requiring precision resistor matching and close TCR tracking over temperature and size. As a replacement for discrete chip resistors, the MPM series combines space savings and superior performance, with resistive elements integrated within a single package onto a common substrate and resulting in near-identical conditions over time and temperature for each element.
The six new optocoupler devices offer designers a choice of single-, dual-, and quad-channel options. The K815P (single), K825P (dual), K845P (quad), TCED1100 (single), TCED2100 (dual), and TCED4100 (quad) feature a gallium arsenide infrared emitting diode coupled with a photo darlington transistor output. Combining a high current transfer ratio of 600% with a very low input current, the new devices provide a stable distance between input and output for maximum safety. Typical applications will include isolation for signal transfer systems, pulse-dial circuits, ring detector circuits, and loop monitor circuits, while the darlington output of these new devices makes them ideal for use in modems, line cards, PBX, and PABX systems where only low-signal currents are available.
