77083103

77083103 Description

The 77083103 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 isolated resistors with a 10kΩ resistance, ±2% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Encased in an 8-pin SIP package, it measures 20.32mm x 2.50mm (0.800" x 0.098") with a seated height of 4.95mm (0.195"), making it suitable for space-constrained layouts. Rated at 100mW per element, it complies with ROHS3 and carries an EAR99 ECCN designation, indicating broad exportability.

77083103 Features

• High Density: Compact SIP package integrates 4 isolated resistors, reducing board space versus discrete components.
• Stable Performance: Low ±100ppm/°C thermal drift ensures reliability in temperature-sensitive circuits.
• Precision Tolerance: ±2% resistance tolerance for applications demanding consistent electrical characteristics.
• Robust Construction: Through-hole mounting provides mechanical stability, ideal for high-vibration environments.
• Compliance: ROHS3 and REACH Unaffected status simplifies regulatory adherence.

77083103 Applications

• Industrial Controls: Signal conditioning and pull-up/pull-down networks in PLCs and sensors.
• Test & Measurement Equipment: Precision voltage dividers and calibration circuits.
• Legacy Electronics Repair: Replacing obsolete resistor networks in vintage audio or instrumentation.
• Power Supplies: Current-limiting or feedback networks in low-power DC/DC converters.

Conclusion of 77083103

While marked obsolete, the 77083103 remains a viable choice for legacy designs or applications requiring high-density, stable resistor networks. Its isolated circuit design, tight tolerance, and through-hole durability make it particularly suited for industrial and precision electronics. Engineers sourcing this part should verify alternative availability or consider it for long-lifecycle projects where performance consistency outweighs obsolescence risks.
