GWCR Green Thick-Film Chip Resistors

Welwyn / TT Electronics GWCR Green Thick-Film Chip Resistors are made from materials, which are completely free of lead and its compounds. This makes the resistors RoHS compliant without relying on the exemption for lead oxide in glass. The use of green chip resistors protects the design against future changes in environmental legislation. A comprehensive range of 1%, 100ppm/°C products suitable for general purpose use is offered in 10 sizes ranging from 01005 to 2512 package sizes. The Welwyn GWCR resistors are available in values from 1R0 to 10M with a ±1% tolerance. The components feature 31mW to 1W ratings with an operating temperature of -55°C to +155°C.
