Digi-Key Corporation Announces New Production Capability for Precision Resistors from Vishay Foil Resistors


THIEF RIVER FALLS, Minnesota, USA --(Business Wire)--

Global electronic components distributor Digi-Key Corporation, recognized by design engineers as having the industry's largest selection of electronic components available for immediate shipment, today announced the addition of Vishay Precision Group's (VPG) precision foil resistors to its vast product line.

VPG's (News - Alert) Vishay Foil Resistors (VFR) brand of bulk metal® foil resistors ? with the lowest TCR, PCR, current noise, thermal EMF, lowest cumulative end-of-life error envelope, and available in very tight tolerances ? are the highest precision resistors in the industry. They are commonly used in the most critical circuits in avionics, military and space (AMS) applications as well as in the medical, measurement/control, energy exploration/production, and automotive industries.

Digi-Key has been, and continues to be, a valued distributor of VFR's most popular precision resistor part numbers. Digi-Key now operates a VFR-approved precision center in which the distributor trims VFR-supplied resistor elements to the exact customer-requested resistance, specified to six-digits. The bulk metal® technology contains all of the operational precision and reliability within the resistor element. Digi-Key's final trimming t the exact resistance value maintains all the inherent performance characteristics of the original element. Now Digi-Key can ship VFR's newer VSM and VSMP models from its own finishing operations.



VSMP Series Foil Resistors

Features:


  • Temperature coefficient of resistance (TCR): 0.05 ppm/°C typical (0 °C to + 60 °C) 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.)
  • Resistance tolerance: to ± 0.01 %
  • Power coefficient "?R due to self-heating": 5 ppm at rated power
  • Power rating: up to 750 mW at 70 °C
  • Load life stability: to ± 0.005 % at 70 °C, 2000 h at rated power
  • Not restricted to standard values, specific "as required" values available (e.g. 1K2345 vs. 1K)
  • Thermal stabilization time < 1 s (nominal value achieved within 10 ppm of steady state value)
  • Electrostatic discharge (ESD) at least to 25 kV
  • Short time overload: =.005 %
  • Non inductive, non-capacitive design

Applications:

  • High-precision applications such as aerospace, medical, measurement/control, energy exploration/production, and special automotive circuits

VPG's foil precision trimmed resistors are available for purchase now on Digi-Key's global websites.
