By eeNews Europe

he resistors range in size from 0402 (0.040 x 0.020 inch) to 2512 (0.025 x 0.025 inch), with tolerances from 0.1%, power ratings from 50 mW to 1500 mW temperature coefficients of resistance as low as 25 ppm, and voltage ratings from 30 V to 200 V. The operating range for these resistors is from -55 to + 125 degrees  C.

The Z Termination is a gold-over-nickel finish which can be attached with solder, conductive epoxy, or gold wire bonds. The Z termination resistors are a RoHS compliant product.

Reliability is assured by extensive in house testing – users can select from a wide variety of testing options which include standard product, Mil-PRF 55342 established reliability (R or S level), or space level to Mil-PRF-55342 "T" product level. Custom testing to customer specifications is also available.

SOTA chip resistors are designed for use in a wide range of high reliability applications including medical electronics, defense systems, microwave communications, aerospace electronics, and satellite systems.

Availability and Pricing

Pricing is generally under $1.50 in manufacturing quantities. Current lead time is eight weeks, but SOTA maintains more than 50 million resistors in stock.

Delivery on stock items is two business days ARO.
