GENERAL DESCRIPTION
The 83 series of Surface mount chip attenuators are designed for direct installation on printed circuit boards and manufactured
using thin film. 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) or BeO. All devices are available RoHS compliant.
