Wilbrecht LEDCO Adds SMT Resistors
St. Paul, MN — Wilbrecht LEDCO, Inc., a subsidiary of Microprecision Electronics SA, is adding surface-mount precision foil resistors to its product line.
The company is now making surface mount models VSM and VSMP (Z-Foil) available to its customers.
These resistors are available in five different sizes (between 0805 and 2512) and are constructed to consistently meet strict low temperature coefficients (TCR) and tight absolute tolerances. The company's Bulk Metal
Foil resistors offer a TCR of ±0.2ppm/°C over the range 55 to +125°C and resistance tolerance to 0.01 percent. The resistors reportedly offer load life stability to ±0.005 percent at 70°C, thermal stabilization time <1 s (nominal value achieved within 10 ppm of steady state value) and electrostatic discharge (ESD) at least to 25kV.
Bulk Metal Foil resistors are not restricted to standard values, but can be trimmed to any "as required" value. The resistors' tight tolerances and high stability also have the advantage of enabling longer intervals between calibrations of the circuit; they, therefore, serve to lower operating costs. The enhanced reliability of the in-circuit reference resistors provide more dependable equipment for several applications, such as military, avionics, deep-space probes, automatic test equipment, sense and measurement equipment, medical equipment and high-end audio equipment.
