Welwyn Components are a designer and manufacturer of a full portfolio of resistor technologies, serving the industrial, defence, automotive and medical sectors.
With a fully comprehensive product offering, Welwyn offer an ohmic value range spanning 18 decades, and many innovations in the field of high power steel resistors, safety qualified fusing resistors and high energy surge tolerant parts.
We stock the full range of Welwyn products.
CR series is a thick film chip resistor designed for high reliability applications. Until now there have been four standard sizes for solder terminations and CR0603 adds a fifth, smaller size to the range. With the same value range 1R0 to 10M, CR0603 provides a high reliability component in compact circuits where footprint is critical.
HR series is a thick film chip resistor designed for high ohmic value applications. Until now there have been two standard sizes for solder terminations and HR0603 adds a third, smaller size to the range. With the value range 10M to 20G, HR0603 provides a stable, high ohmic value component in compact circuits where footprint is critical.
The WMHP-HS is a PCB mounting heatsink tailored for WMHP series power resistors. It is a compact and lightweight thermal management solution with a small PCB footprint. It can accommodate both TO-220 and TO-247 package styles, thus covering the whole range of WMHP ratings from 20 to 100W.
For circuit designers who need to manage temperature rise in compact power electronic assemblies we provide WMHP-HS which provides more effective cooling with lower mass than the key competing part (Ohmite)
