770103391

770103391 Description

The 770103391 from CTS Resistor Products (a division of CTS Corporation) is a 5-resistor isolated network designed for precision through-hole applications. This 390Ω, ±2% tolerance array offers a compact footprint with dimensions of 1.000" L x 0.098" W (25.40mm x 2.50mm) and a seated height of 0.195" (4.95mm), making it suitable for space-constrained PCB designs. The device operates with a ±100ppm/°C temperature coefficient, ensuring stable performance across varying environmental conditions. Rated at 100mW per element, it is housed in a 10-pin SIP (Single In-line Package) and supplied in bulk packaging. Though marked Obsolete, it remains ROHS3 Compliant and REACH Unaffected, adhering to modern environmental standards.

770103391 Features

• High Precision: ±2% tolerance and ±100ppm/°C thermal stability for reliable circuit performance.
• Compact Design: Slim 2.50mm width and low-profile 4.95mm height ideal for dense layouts.
• Isolated Circuitry: Independent resistors reduce crosstalk in multi-channel applications.
• Robust Power Handling: 100mW per element supports moderate power dissipation.
• Compliance: Meets ROHS3 and REACH requirements despite obsolete status.
• Through-Hole Reliability: 10-pin SIP ensures secure mounting for industrial environments.

770103391 Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers or sensor interfaces in measurement systems.
• Legacy Electronics Repair: Replacing obsolete arrays in vintage audio or test equipment.
• Industrial Control Systems: Isolated bias networks or pull-up/down configurations in PLCs.
• Power Supply Circuits: Current-limiting or feedback networks in low-power DC/DC converters.
• Educational Prototyping: Breadboard-friendly SIP package for student projects.

Conclusion of 770103391

The 770103391 balances precision, compactness, and compliance, making it a pragmatic choice for legacy upgrades or niche designs requiring isolated through-hole resistor arrays. While obsolete, its 390Ω value, 100mW rating, and environmental certifications ensure continued utility in industrial, educational, and repair scenarios where reliability and space efficiency are critical. Engineers should evaluate alternative active-series models for new designs but may leverage this component for backward compatibility.
