This article describes the High-Precision, High-Stability Resistors (CSC9270LDGP). The principle is very simple, very practical. The circuit components can help you understand better grasp this principle. For example, in this circuit, you can go to find and buy these components: CSC9270LDGP.

Vishay Intertechnology, Inc. (VSH:NYSE) today released a new surface-mount series of high-precision, high-stability metal film resistors in the 2012 and 4527 case sizes. For excellent stability across a range of environmental conditions, thePSFresistors feature extremely low temperature coefficients down to ± 5 ppm/°C and tight tolerances to 0.01 %.

Offering circuit designers a surface-mount version of Vishay’s axial-leadedPTFseries, thePSFdevices are optimized for high-precision applications in precision test and measurement systems and military, aerospace, and industrial equipment and instrumentation.

Measuring 0.200 in. by 0.125 in. [5.08 mm by 3.18 mm] with a 0.096 in. [2.44 mm] profile, the PSF2012 offers a 0.125 W power rating and 200 V working voltage. The PSF4527 measures 0.455 in. by 0.275 in. [11.56 mm by 6.98 mm] with a 0.167 in. [4.24 mm] profile, and features a 0.25 W power rating and 300 V working voltage.

The device offers compliant wraparound terminations that eliminate the risk of solder fillet cracking due to differences in coefficient of thermal expansion (CTE), as well as a rugged molded encapsulation to optimize performance in harsh environments. The resistors operate over a temperature range of ?55°C to 150°C.

Samples and production quantities of thePSFresistors are available now, with lead times of 15 to 18 weeks.
