770101822 Description

The 770101822 from CTS Resistor Products (a division of CTS Corporation) is a 9-resistor bussed network designed for through-hole mounting. This obsolete but REACH-unaffected component features a compact 1.000" L × 0.098" W (25.40mm × 2.50mm) footprint with a 10-pin SIP configuration, offering a 8.2kΩ resistance per element at ±2% tolerance. Its ±100ppm/°C temperature coefficient ensures stable performance across varying thermal conditions, while the 100mW power rating per element suits low-to-moderate power applications. The non-MSL (Not Applicable) rating and ROHS3 compliance make it environmentally robust, though availability may be limited due to its obsolete status.

770101822 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a shared configuration, reducing wiring complexity.
• High-Density Design: 9 resistors integrated into a 10-pin SIP package, optimizing board space.
• Stable Performance: ±100ppm/°C thermal drift ensures reliability in temperature-sensitive environments.
• Through-Hole Durability: Robust construction for mechanical stability in industrial applications.
• Compliance: ROHS3 and EAR99/ECCN certified, with REACH unaffected status for global use.

770101822 Applications

Ideal for legacy or maintenance designs requiring precision resistor networks, such as:

• Analog Signal Conditioning: Voltage dividers, pull-up/pull-down networks in sensor interfaces.
• Industrial Control Systems: PLCs, motor drives, and power supplies where bussed resistors reduce component count.
• Test & Measurement Equipment: Calibration circuits or reference networks demanding tight tolerance (±2%).
• Retrofit Projects: Replacing older 8.2kΩ arrays in telecom or audio equipment.

Conclusion of 770101822

While obsolete, the 770101822 remains a viable choice for space-constrained, low-power designs needing stable, bussed resistance values. Its through-hole SIP package and 100mW power handling cater to rugged applications, though designers should verify alternative modern equivalents for new projects. CTS’s legacy of reliability ensures this network meets stringent performance criteria for niche or legacy systems.
