4608X-101-183 Description

The 4608X-101-183 is a 7-resistor bussed network from Bourns Inc.'s 4600X series, designed for through-hole mounting. It features a compact 8-pin SIP (Single In-Line Package) with a 18kΩ resistance per element and a tight ±2% tolerance, ensuring reliable performance in precision circuits. The device operates within a ±100ppm/°C temperature coefficient, making it suitable for environments with moderate thermal fluctuations. With a 200mW power rating per resistor and a 0.798" x 0.098" (20.27mm x 2.49mm) footprint, it balances power handling and space efficiency. Although marked as Obsolete, it remains REACH compliant and MSL-exempt, ideal for legacy or low-risk applications.

4608X-101-183 Features

• High-Density Integration: Combines 7 resistors in an 8-pin SIP, reducing board space versus discrete components.
• Stable Performance: ±2% tolerance and ±100ppm/°C TCR ensure consistent operation in analog/digital circuits.
• Robust Construction: Through-hole design enhances mechanical stability for harsh environments.
• Legacy Compatibility: Obsolete status but unaffected by REACH, suitable for maintenance or repairs.
