4606X-101-183 Description

The 4606X-101-183 from Bourns Inc. is a 5-resistor bussed network housed in a 6-pin SIP (Single In-line Package) configuration. Designed for through-hole mounting, this 18kΩ ±2% tolerance array offers a compact footprint of 0.598" × 0.098" (15.19mm × 2.49mm) with a seated height of 0.200" (5.08mm), making it suitable for space-constrained PCB designs. The device operates with a ±100ppm/°C temperature coefficient and delivers 200mW power per element, ensuring stable performance across industrial temperature ranges. Although marked Obsolete, it remains REACH-compliant and falls under ECCN EAR99, simplifying regulatory compliance for legacy systems.

4606X-101-183 Features

• High-Density Integration: Combines 5 resistors in a single SIP package, reducing board space and assembly complexity.
• Precision Tolerance: ±2% resistance accuracy and ±100ppm/°C thermal stability for reliable signal conditioning.
• Robust Construction: Through-hole design ensures mechanical durability, ideal for high-vibration environments.
• Simplified Circuit Design: Bussed topology (common-pin configuration) streamlines layout in voltage-divider or pull-up/pull-down networks.
• Compliance Ready: REACH Unaffected and MSL Not Applicable, eliminating moisture-handling constraints.

4606X-101-183 Applications

• Legacy Industrial Controls: Replacement or repair of aging equipment requiring stable, high-density resistor networks.
• Power Supply Circuits: Voltage division and current-limiting in linear regulators or feedback loops.
• Automotive Electronics: Sensor interfaces or ECU signal conditioning where through-hole reliability is critical.
• Test & Measurement: Calibration circuits or reference networks demanding tight tolerance (±2%) and low thermal drift.

Conclusion of 4606X-101-183

The 4606X-101-183 balances compact integration with precision performance, catering to legacy and ruggedized applications. Its bussed architecture and through-hole robustness make it a pragmatic choice for designs prioritizing durability over miniaturization. While obsolete, its REACH compliance and industrial-grade specs ensure continued utility in maintenance cycles or niche replacements. Engineers should evaluate alternative 4600X-series models for active designs but can leverage this array for cost-effective, high-reliability solutions in constrained scenarios.
