770101331 Description

The 770101331 from CTS Resistor Products (a division of CTS Corporation) is a 9-resistor bussed network designed for through-hole mounting. This obsolete but reliable component features a compact 1.000" x 0.098" (25.40mm x 2.50mm) SIP package with 10 pins, offering a 330Ω resistance per element at ±2% tolerance. With a ±100ppm/°C temperature coefficient and 100mW power rating per resistor, it ensures stable performance in moderate-power applications. The ROHS3-compliant and REACH-unaffected construction makes it suitable for legacy designs adhering to environmental standards.

770101331 Features

• Bussed Circuit Configuration: Simplifies PCB layout by connecting resistors in a common-node topology, reducing wiring complexity.
• High-Density SIP Package: Space-efficient 10-pin design with a 0.195" (4.95mm) seated height, ideal for vertical board mounting.
• Robust Tolerance & Stability: ±2% tolerance and ±100ppm/°C TCR ensure consistent performance across temperature fluctuations.
• Legacy Compliance: EAR99 and HTSUS 8533.21.0050 classifications facilitate global logistics for obsolete inventory.
• Non-MSIL: Not moisture-sensitive, eliminating baking requirements for storage or assembly.
