Vishay's New CSM2512S Bulk Metal® Surface-Mount Power Metal Strip® Resistor Offers Improved Load-Life Stability of 0.05%, Absolute TCR of ±15 ppm/°C, and Tolerance of ±0.1%
High-Precision Current Sensing Device Features Resistance Values
From 10 mW and Rated Power to 1 W in a 4-Terminal Kelvin Design
MALVERN, PENNSYLVANIA - June 27, 2008 - Vishay Intertechnology, Inc. today announced a new high-precision Bulk Metal® surface-mount Power Metal Strip® resistor that features an improved load-life stability of ±0.05% at +70°C for 2000 hours at rated power, an absolute TCR of ±15 PPM/°C from -55°C to +125°C, +25°C Ref., and a tolerance of ±0.1%.
Typical current sensing resistors offer a load-life stability of 0.5% through a 1000-hour workload. The improved resistance stability of the CSM2512S makes it ideal for tightened-stability voltage division and precision current sensing applications in switching linear power supplies, power amplifiers, measurement instrumentation, bridge networks, and medical and test equipment. In addition, the CSM2512S complies with EEE-INST-002 (MIL-PRF 55342 and MIL-PRF 49465) for military and space applications.
The CSM2512S's all-welded construction is composed of a Bulk Metal® resistive element with plated copper terminations. The resistor element is designed to uniformly dissipate power in order to minimize hot spots, and is compatible with the lead material, resulting in a low thermal EMF of 3 µV/°C.
The CSM2512S provides a 1-W power rating and maximum current up to 18A in a four-terminal Kelvin configuration for increased accuracy. Any value at any tolerance is available within the resistance range of 10 mW to 100 mW at no additional cost.
Samples and production quantities of the CSM2512S high-precision resistor are available now, with lead times of 72 hours for samples, and three weeks for standard orders. Pricing for U.S. delivery starts at $2.00.
