Features & Benefits

Our attenuators are available in a low power chip package as well as a 0.250 sq high power BeO package. The input power ratings range from 0.1 to 120 watts. The attenuation values range from 0 dB to 20 dB with 30 dB available on some devices. The terminals of our chip attenuators are made with thick film material. 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, QFA 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.
