1776-C681

1776-C681 Description

The 1776-C681 from Caddock Electronics Inc. is a high-precision 5-resistor network designed for voltage divider applications requiring tight TCR (Temperature Coefficient of Resistance) matching. Housed in a 10SIP (Single In-line Package), it features resistances of 1kΩ, 9kΩ, 90kΩ, 900kΩ, and 9MΩ with an exceptional ±0.1% tolerance and ±0.05% resistor matching ratio. The device operates with a power rating of 62.5mW per element and exhibits a low ±30ppm/°C temperature coefficient, ensuring stability across varying environmental conditions. Its ±10ppm/°C resistor-ratio drift further enhances performance in precision circuits.
