77083561 Description

The 77083561 from CTS Resistor Products (a division of CTS Corporation) is a 4-resistor network designed for precision applications in through-hole mounting configurations. This obsolete yet reliable component features a compact 8-pin SIP package with isolated circuit topology, offering 560Ω resistance per element at a tight ±2% tolerance. Its ±100ppm/°C temperature coefficient ensures stable performance across varying thermal conditions, while the 100mW power rating per element balances efficiency with durability. The ROHS3-compliant and REACH-unaffected construction adheres to environmental standards, and its non-MSLA (Moisture Sensitivity Level Not Applicable) status simplifies handling and storage.

77083561 Features

• High-Density Design: Compact 0.800" x 0.098" (20.32mm x 2.50mm) footprint with 0.195" (4.95mm) seated height optimizes board space.
• Precision Performance: ±2% tolerance and ±100ppm/°C TCR ensure consistent signal integrity in critical circuits.
• Robust Construction: Through-hole mounting provides mechanical stability for harsh environments.
• Compliance: Meets ROHS3 and EAR99/ECCN requirements for global deployment.
• Isolated Circuitry: Independent resistors reduce crosstalk, ideal for analog/digital signal separation.

77083561 Applications

This resistor network excels in:

• Industrial Control Systems: Precision voltage division and current limiting in PLCs and sensors.
• Legacy Electronics Repair: Replacement for obsolete designs due to standardized SIP packaging.
• Test & Measurement Equipment: Stable reference resistors for calibration circuits.
• Power Supplies: Snubber networks or feedback loops requiring matched resistance values.

Conclusion of 77083561

While marked obsolete, the 77083561 remains a viable solution for legacy systems or designs prioritizing through-hole reliability and isolated resistor performance. Its 560Ω resistance, tight tolerance, and low TCR make it suitable for precision applications where newer SMD alternatives may not be compatible. Engineers seeking a proven, compliant resistor array for industrial or retrofitted systems will find this model a pragmatic choice.
