4608X-101-103

4608X-101-103 Description

The 4608X-101-103 is a 7-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting in compact electronic assemblies. This obsolete but reliable component features a 10kΩ resistance per element with a tight ±2% tolerance, ensuring consistent performance in precision circuits. Its ±100ppm/°C temperature coefficient provides stable operation across varying thermal conditions. The array is housed in an 8-pin SIP package with dimensions of 0.798" x 0.098" (20.27mm x 2.49mm) and a seated height of 0.200" (5.08mm), making it suitable for space-constrained applications. Rated at 200mW per resistor, it balances power handling and miniaturization.

4608X-101-103 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node topology.
• High Power Handling: 200mW per element outperforms many thin-film arrays in power dissipation.
• Stable Performance: ±100ppm/°C TCR ensures minimal resistance drift under thermal stress.
• Robust Construction: Through-hole design enhances mechanical durability versus surface-mount alternatives.
• REACH Compliance: Unaffected by REACH restrictions, ensuring long-term supply chain flexibility for legacy designs.

4608X-101-103 Applications

Ideal for analog signal conditioning, voltage division, and pull-up/pull-down networks in industrial controls, test equipment, and automotive electronics. Its bussed architecture suits bus termination and I/O port protection in microcontroller-based systems. The MSL "Not Applicable" rating makes it resilient in humid environments, while the EAR99/ECCN classification ensures export compliance for global deployments.

Conclusion of 4608X-101-103

While marked obsolete, the 4608X-101-103 remains a robust choice for legacy designs requiring high-density, precision resistor networks. Its combination of power handling, stability, and compact form factor makes it a cost-effective solution for retrofit projects or low-volume production where newer alternatives may not meet dimensional or electrical constraints.
