4605X-101-680LF Description

The 4605X-101-680LF from Bourns Inc. is a high-performance resistor network designed for precision applications in electronic circuits. This 4-resistor bussed array features a compact through-hole SIP package with a resistance value of 68Ω per element and a tight tolerance of ±1Ω, ensuring reliable signal conditioning and voltage division. With a ±250ppm/°C temperature coefficient, it maintains stable performance across varying thermal conditions. The device is housed in a 0.498" x 0.098" (12.65mm x 2.49mm) footprint, making it suitable for space-constrained designs while delivering 200mW power dissipation per element. Its ROHS3 compliance and REACH unaffected status align with modern environmental standards.

4605X-101-680LF Features

• 4-resistor bussed network with 68Ω resistance and ±1Ω tolerance for consistent performance.
• Compact SIP package (5 pins, 0.200" seated height) ideal for dense PCB layouts.
• Low TCR (±250ppm/°C) ensures minimal resistance drift under thermal stress.
• 200mW power rating per resistor balances current handling and thermal management.
• Tape & Reel (TR) packaging streamlines automated assembly processes.
