4604X-101-181LF Description

The 4604X-101-181LF from Bourns Inc. is a high-performance 3-resistor bussed network designed for precision through-hole applications. Part of the 4600X series, this resistor array features a compact SIP (Single Inline Package) with dimensions of 0.398" x 0.098" (10.11mm x 2.49mm) and a seated height of 0.200" (5.08mm). It offers a 180Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The 200mW power rating per resistor and 50ppm/°C resistor-ratio drift make it suitable for demanding circuits requiring consistent signal integrity.

4604X-101-181LF Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node arrangement.
• Robust Construction: Through-hole mounting ensures mechanical stability for industrial environments.
• Low Drift & High Stability: ±100ppm/°C TCR and 50ppm/°C ratio drift minimize performance variations.
• Compliance: ROHS3 Compliant and REACH Unaffected, meeting global environmental standards.
• Wide Operating Range: Not MSL-rated (Moisture Sensitivity Level), making it ideal for non-hygroscopic applications.
