4814P-1-181

4814P-1-181 Description

The 4814P-1-181 from Bourns Inc. is a high-performance 7-resistor array designed for precision surface-mount applications. With a 180Ω resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in compact circuits. Housed in a 14-pin SOIC package, it features a 0.390" x 0.220" (9.91mm x 5.59mm) footprint and a low-profile 2.40mm seated height, making it ideal for space-constrained designs. The isolated circuit configuration allows independent resistor operation, while its ±100ppm/°C temperature coefficient ensures stability across varying environmental conditions. Compliant with REACH and ECCN EAR99, it is packaged in Tape & Reel (TR) for automated assembly efficiency.
