4605X-101-472LF Description

The 4605X-101-472LF from Bourns Inc. is a high-performance resistor network designed for precision applications in electronic circuits. This 4-resistor bussed array offers a 4.7kΩ resistance per element with a tight ±2% tolerance, ensuring reliable signal conditioning and voltage division. Encased in a through-hole SIP package (5 pins), it features a compact 0.498" x 0.098" (12.65mm x 2.49mm) footprint and a low-profile 5.08mm seated height, making it suitable for space-constrained designs. With a 200mW power rating per element and a ±100ppm/°C temperature coefficient, it delivers stable performance across varying environmental conditions.

4605X-101-472LF Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node topology.
• Robust Construction: Through-hole mounting ensures mechanical durability and ease of assembly.
• Wide Compatibility: ROHS3 and REACH compliant, meeting global environmental standards.
• Low Sensitivity: MSL "Not Applicable" rating eliminates moisture-related handling concerns.
• High Power Handling: 200mW per resistor supports demanding applications without derating.
• Stable Performance: ±100ppm/°C TCR minimizes resistance drift over temperature fluctuations.

4605X-101-472LF Applications

Ideal for industrial control systems, automotive electronics, and instrumentation, the 4605X-101-472LF excels in:
