77081222 Description

The 77081222 from CTS Resistor Products (a division of CTS Corporation) is a 7-resistor bussed network designed for through-hole mounting. This obsolete but REACH-unaffected component features a compact 8-pin SIP package with dimensions of 0.800" x 0.098" (20.32mm x 2.50mm) and a seated height of 0.195" (4.95mm). Each resistor in the array has a 2.2kΩ resistance with a tight ±2% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. The 100mW power rating per element and ROHS3 compliance make it suitable for legacy or environmentally conscious designs.

77081222 Features

• Bussed Circuit Topology: Simplifies PCB layout by connecting resistors in a common configuration, reducing component count.
• High Power Handling: 100mW per resistor enables robust performance in analog and digital circuits.
• Precision Tolerance: ±2% resistance accuracy ensures reliable signal conditioning and voltage division.
• Wide Operating Range: ±100ppm/°C temperature coefficient minimizes drift in industrial or automotive environments.
• Through-Hole Reliability: Robust 8-pin SIP package suits wave soldering and high-vibration applications.

77081222 Applications

• Legacy Industrial Controls: Ideal for PLCs, sensor interfaces, and power supply feedback circuits requiring stable resistance networks.
• Automotive Electronics: Used in dashboard clusters or ECU signal conditioning due to vibration-resistant through-hole construction.
• Test & Measurement Equipment: Precision tolerance suits calibration circuits and reference voltage dividers.
• Consumer Electronics: Found in older audio equipment or CRT displays where bussed networks simplify design.

Conclusion of 77081222

While marked obsolete, the 77081222 remains a viable choice for repairs or legacy systems demanding high-density, precision resistance networks. Its bussed design, 100mW power rating, and ±2% tolerance offer advantages over discrete resistors in space-constrained applications. Engineers valuing simplicity, durability, and RoHS compliance may still source this model for niche industrial or automotive uses. For new designs, consider modern alternatives from CTS’s active series with similar specifications.
