4608X-101-181 Description

The 4608X-101-181 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 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. Each resistor in the array offers a 180Ω resistance with a tight ±2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The network operates at 200mW power per element and is supplied in bulk packaging, catering to high-volume production needs.

4608X-101-181 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node arrangement, reducing wiring complexity.
• High Power Handling: 200mW per resistor ensures reliability in power-sensitive circuits.
• Stable Performance: ±100ppm/°C temperature coefficient minimizes resistance drift under thermal stress.
• Compact SIP Package: Ideal for dense PCB designs, with a low-profile 5.08mm max height.
• REACH Compliance: Unaffected by REACH regulations, ensuring long-term availability for industrial use.
• Obsolete Status: While no longer in production, it remains a robust choice for legacy system maintenance.

4608X-101-181 Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and pull-up/pull-down networks in sensor interfaces.
• Legacy Industrial Equipment: Repair and replacement for obsolete systems requiring stable, high-density resistor arrays.
• Power Supply Circuits: Current-limiting and load-sharing applications due to its 200mW power rating.
• Automotive Electronics: Suitable for non-critical subsystems where bussed configurations reduce part count.
