4608X-101-271

4608X-101-271 Description

The 4608X-101-271 from Bourns Inc. is a 7-resistor bussed network housed in an 8-pin SIP (Single In-line Package) configuration. Designed for through-hole mounting, this 270Ω ±2% tolerance array offers a compact footprint of 0.798" x 0.098" (20.27mm x 2.49mm) with a seated height of 0.200" (5.08mm). Operating within a ±100ppm/°C temperature coefficient, it ensures stable performance across varying environmental conditions. Each resistor delivers 200mW power dissipation, making it suitable for moderate-load applications. The REACH-unaffected, EAR99-compliant device is supplied in bulk packaging and is marked as obsolete, though it remains a reliable choice for legacy designs.

4608X-101-271 Features

• High-Density Integration: Combines 7 resistors in a single 8-pin SIP, reducing PCB space and assembly complexity.
• Precision Tolerance: ±2% resistance tolerance ensures consistent performance in precision circuits.
• Robust Thermal Performance: ±100ppm/°C temperature coefficient minimizes resistance drift under thermal stress.
• Legacy Compatibility: Ideal for maintaining or servicing older systems due to its through-hole design and bussed topology.
• Power Handling: 200mW per element supports moderate current applications without derating concerns.

4608X-101-271 Applications

• Industrial Control Systems: Used in PLCs and sensor interfaces for signal conditioning and pull-up/pull-down networks.
• Legacy Electronics Repair: Replaces or replicates resistor arrays in vintage audio equipment, test instruments, and telecom hardware.
• Power Supply Circuits: Acts as a current-limiting or voltage-dividing component in low-power DC/DC converters.
• Automotive Electronics: Suitable for non-critical subsystems like dashboard lighting or infotainment where through-hole reliability is preferred.

Conclusion of 4608X-101-271

The 4608X-101-271 resistor network balances compact integration, stable performance, and ease of use in through-hole designs. While obsolete, its 270Ω bussed configuration, ±2% tolerance, and 200mW power rating make it a pragmatic choice for legacy maintenance or space-constrained analog circuits. Engineers valuing thermal stability and proven durability will find it particularly useful in industrial and automotive retrofits. For new designs, Bourns' modern equivalents may offer enhanced features, but this model remains a cost-effective solution for specific use cases.
