6943R1KBLF

6943R1KBLF Description

The 6943R1KBLF from TT Electronics / BI Technologies is a high-precision 4-resistor network housed in an 8-pin DIP package. Designed for demanding applications, it features a 1kΩ resistance per element with an ultra-tight ±0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring exceptional stability across operating conditions. The isolated circuit configuration and ±0.1% resistor matching ratio make it ideal for precision analog designs. With a compact footprint of 9.52mm x 6.35mm (0.375" x 0.250") and a 100mW power rating per element, this obsolete but REACH-compliant component remains a reliable choice for legacy systems.

6943R1KBLF Features

• Precision Performance: ±0.1% tolerance and ±25ppm/°C TCR ensure minimal drift in critical circuits.
• Matched Resistor Network: ±0.1% ratio matching and ±5ppm/°C ratio drift enhance differential signal accuracy.
• Robust Construction: Through-hole mounting with a 4.32mm (0.170") seated height for mechanical stability.
