77083473 Description

The 77083473 from CTS Resistor Products (a division of CTS Corporation) is a 4-resistor network designed for precision through-hole applications. This obsolete but REACH-unaffected component features 47kΩ resistance per element with a tight ±2% tolerance, ensuring reliable performance in demanding circuits. Its isolated circuit type allows independent resistor operation, while the ±100ppm/°C temperature coefficient guarantees stability across varying thermal conditions. Encased in an 8-pin SIP package with dimensions of 0.800" x 0.098" (20.32mm x 2.50mm) and a seated height of 4.95mm, it suits space-constrained layouts. Rated at 100mW per element, this RoHS3-compliant array is ideal for legacy designs requiring bulk packaging and non-MSLA compliance.

77083473 Features

• High Precision: ±2% tolerance and low TCR (±100ppm/°C) for stable performance.
• Compact Design: Slim 2.50mm width and 8-pin SIP configuration save PCB space.
• Isolated Circuitry: Independent resistors enable flexible circuit design.
• Durable Construction: Through-hole mounting ensures mechanical robustness.
• Compliance: RoHS3 compliant and REACH unaffected, meeting environmental standards.
• Legacy Support: Bulk packaging and obsolete status cater to maintenance/repair scenarios.

77083473 Applications

• Analog Signal Conditioning: Precision voltage dividers in sensor interfaces.
• Industrial Controls: Feedback networks in PLCs and motor drivers.
• Legacy Electronics: Repair/replacement for obsolete equipment.
• Test & Measurement: Calibration circuits requiring stable resistance values.
• Power Management: Load balancing in low-power DC/DC converters.

Conclusion of 77083473

The 77083473 resistor network excels in applications demanding precision, isolation, and compactness, despite its obsolete status. Its low TCR, tight tolerance, and through-hole reliability make it a pragmatic choice for industrial, legacy, and measurement systems. While newer alternatives exist, this model remains valuable for specific repair or niche design needs, backed by CTS Corporation’s legacy of quality. Engineers should evaluate its 100mW power rating and non-MSLA status to ensure compatibility with target use cases.
