4605M-101-122LF Description

The 4605M-101-122LF from Bourns Inc. is a high-performance 4-resistor bussed network designed for precision applications. Part of the 4600M series, this through-hole-mounted array features a compact 0.498" × 0.098" (12.65mm × 2.49mm) footprint with a 1.2kΩ resistance per element and a tight ±2% tolerance. Its ±100ppm/°C temperature coefficient and 50ppm/°C resistor-ratio drift ensure stable performance across varying environmental conditions. The device is ROHS3 compliant and REACH unaffected, making it suitable for environmentally conscious designs. With a 250mW power rating per element and 5-pin SIP configuration, it balances power handling and space efficiency.

4605M-101-122LF Features

• Bussed Circuit Topology: Simplifies PCB layout by sharing a common node, reducing wiring complexity.
• High Stability: Low 50ppm/°C ratio drift and ±100ppm/°C TCR minimize resistance variations under thermal stress.
• Robust Construction: 6.35mm max height and through-hole mounting ensure mechanical durability.
• Wide Compatibility: EAR99 ECCN and HTSUS 8533.21.0050 classifications facilitate global sourcing.
• Reliability: MSL Not Applicable rating eliminates moisture sensitivity concerns during storage or assembly.
