Provides specifications for 898 and 899 dual-in-line thick film resistor networks.
This document provides technical specifications for the TT Electronics Models 898 and 899 Dual-In-Line Thick Film Resistor Networks. It covers standard resistance ranges from 10 Ohms to 10 Megohms with tolerances of ±2% or optional ±1%, and an operating temperature range of -55°C to +125°C.
The datasheet details environmental performance based on MIL-R-83401 standards, including thermal shock, moisture resistance, and solderability. It also provides mechanical outline dimensions for both models (Model 898 with 16 leads and Model 899 with 14 leads) and explains circuit configurations such as isolated resistors, bussed resistors, and dual terminators.
