DIP-1989-02-2002-B Description

The DIP-1989-02-2002-B by TT Electronics/IRC is a high-precision 14-pin ceramic DIP thin-film resistor network, designed for demanding electronic applications requiring stable performance under elevated temperatures. This isolated (ISOL) circuit-type network comprises 7 resistors, each rated at 20 kΩ with a tight tolerance of 0.1% and a ±50 ppm/°C temperature coefficient, ensuring minimal resistance drift across its operating range of 70°C to 150°C. The ceramic case style enhances thermal stability, while the through-hole pin termination facilitates robust PCB mounting. With a total power rating of 1.4W (0.2W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in precision circuits.
