Features & Benefits

Terminals are nickel plated and solder coated or silver over nickel RoHS compliant lead free. Our chip attenuators are available with thick film resist, tantalum nitride or nichrome thin film resist materials. The TS04, TS05, TS07, TS09, TT9, KFA and HPCA series use thick film resistor elements. The devices are available for shipping in tray or tape and reel packaging. 

Surface mount chip attenuators are designed for direct installation on printed circuit boards. Edge metallization on two sides forms the solder fillets for stronger attachment, easier inspection, and increased heat removal area. The devices are available in Alumina, Aluminum Nitride (AlN), BeO and CVD diamond . All devices are available RoHS compliant.
