HC3-5509B-5

Telecom Overview

The HC3-5509B-5 is a fixed resistor manufactured by Harris Corporation. It is a metal film, through-hole axial leaded component with a power rating of 0.125W and a resistance value of 29800 ohms. The device operates within a voltage range up to 200V and features a tolerance of +/-0.1%. It exhibits a temperature coefficient of 50ppm/Cel and functions across an operating temperature range from -65°C to 175°C. The package is tubular with epoxy coating for moisture protection.

Telecom Feature Summary

• High precision construction utilizing materials similar to MIL-PRF-55182 standards
• Epoxy coating provides superior moisture protection
• Low noise characteristics rated at -40 dB

Telecom Applications

• Precision analog signal conditioning circuits
• High-reliability aerospace instrumentation
• Military-grade electronic assemblies requiring strict tolerance control

Telecom Procurement Notes

Verify the manufacturer origin carefully as Harris Corporation's electronics division has undergone corporate restructuring. Confirm that the specific part number HC3-5509B-5 corresponds to current Vishay Dale production or legacy stock. Ensure compliance with RoHS directives if required for modern assembly processes. Request full traceability documentation for material processing history.

Telecom Selection Notes

Select this component when high stability and low noise are critical in axial leaded applications. The 0.1% tolerance and 50ppm/Cel coefficient make it suitable for precision measurement systems. Consider the 175°C maximum operating temperature for high-thermal environments. Verify physical dimensions against PCB layout constraints before finalizing the design.

Telecom Part Context

This component belongs to the ERC industrial series of metal film resistors. These parts are designed to meet rigorous military specifications while offering commercial availability. The series emphasizes stabilization and screening tests prior to shipping. They serve as robust passive components in demanding electronic environments.

Telecom Replacement Considerations

Direct substitutes must match the 29800 ohm resistance, 0.1% tolerance, and 0.125W power rating. Verify that alternative axial leaded metal film resistors offer comparable temperature coefficients and noise levels. Ensure physical package dimensions are compatible with existing mounting structures.
