4814P-2-391LF

4814P-2-391LF Description

The 4814P-2-391LF from Bourns Inc. is a high-performance 13-resistor bussed network housed in a compact 14-pin SOIC package, designed for precision surface-mount applications. With a 390Ω resistance per element and a tight ±2% tolerance, this device ensures reliable signal conditioning and voltage division in demanding circuits. Its ±100ppm/°C temperature coefficient guarantees stable performance across varying thermal conditions, while the 80mW power rating per resistor balances efficiency with robustness. The 0.390" x 0.220" (9.91mm x 5.59mm) footprint and 2.40mm profile make it ideal for space-constrained PCB designs. Compliant with ROHS3 and REACH, it meets stringent environmental standards.
