4308M-101-124LF Description

The 4308M-101-124LF from Bourns Inc. is a high-performance 7-resistor bussed network designed for precision applications in electronic circuits. This through-hole-mounted array features a 120k ohm resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift provide excellent stability across varying environmental conditions. Encased in a compact 8-pin SIP package with dimensions of 0.784" x 0.085" (19.91mm x 2.16mm), it balances space efficiency with robust 250mW power handling per element. Compliant with ROHS3 and REACH standards, it suits modern eco-conscious designs.

4308M-101-124LF Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common-node configuration.
• High Stability: Low TCR (±100ppm/°C) and ratio drift (50ppm/°C) ensure minimal performance variation under thermal stress.
• Durable Construction: 6.35mm max height and through-hole mounting enhance mechanical reliability.
• Wide Compatibility: EAR99/ECCN and HTSUS 8533.21.0050 classifications facilitate global logistics.
• Industrial-Grade: MSL Not Applicable makes it resilient in humid environments, ideal for harsh conditions.
