770103271 Description

The 770103271 from CTS Resistor Products (a division of CTS Corporation) is a 5-resistor isolated network designed for precision through-hole applications. This obsolete but REACH-unaffected component features a compact 10-pin SIP package with a 270Ω resistance per element, offering ±2% tolerance and a ±100ppm/°C temperature coefficient. Its 100mW power rating per resistor and isolated circuit type ensure reliable performance in distributed load scenarios. The network’s 1.000" x 0.098" (25.40mm x 2.50mm) footprint and 4.95mm seated height make it suitable for space-constrained PCB designs. Compliant with ROHS3 and classified under ECCN EAR99, it meets stringent environmental and regulatory standards.

770103271 Features

• High Density: 5 isolated resistors in a 10-pin SIP package optimize board space.
• Stable Performance: ±100ppm/°C thermal stability ensures minimal resistance drift across operating temperatures.
• Precision Tolerance: ±2% tolerance guarantees consistent performance in critical circuits.
• Robust Construction: Through-hole mounting provides mechanical durability for harsh environments.
• Compliance: ROHS3 and REACH unaffected, ideal for legacy or regulated designs.
• Power Handling: 100mW per element balances current capacity with compact sizing.

770103271 Applications

• Legacy Industrial Controls: Replacement or repair of aging equipment requiring stable resistor networks.
• Test & Measurement: Precision voltage dividers or calibration circuits benefiting from low thermal drift.
• Power Supply Modules: Current-limiting or feedback networks in linear regulators.
• Automotive Electronics: Auxiliary systems where through-hole reliability is preferred over SMD.
• Medical Devices: Low-noise signal conditioning in obsolete but still operational hardware.

Conclusion of 770103271

While marked obsolete, the 770103271 remains a viable solution for maintenance, repair, or niche designs demanding through-hole reliability, precision tolerance, and thermal stability. Its isolated 5-resistor array and 100mW power handling distinguish it from lower-density or surface-mount alternatives. Ideal for legacy systems or applications requiring ROHS-compliant, high-stability resistors, this network balances performance with historical design compatibility. Engineers sourcing replacements or servicing older equipment will find its specifications align with rigorous industrial requirements.
