1-2176742-1

Overview

The TE Connectivity 1-2176742-1 is a fixed film resistor belonging to the MELF (Metal Electrode Leadless Face) component family. It features an axial leadless surface-mount package designed for automated assembly processes. The device utilizes a stable metal glaze resistive element encapsulated in a hermetic glass envelope, providing robust protection against environmental stressors such as moisture and chemical exposure. This construction ensures high reliability and long-term stability in demanding electronic applications.

Feature Summary

• Hermetically sealed glass envelope provides superior environmental protection and moisture resistance compared to standard carbon composition types.
• Axial leadless surface-mount design facilitates efficient automated placement and soldering on printed circuit boards.
• Metal glaze resistive element offers excellent thermal stability and low noise characteristics under varying operating conditions.

Applications

• Industrial control systems requiring high-reliability passive components
• Automotive electronics subject to harsh thermal and vibrational environments
• Medical instrumentation demanding precise signal integrity and longevity

Procurement Notes

Verify the specific tolerance and power rating requirements against your schematic before ordering. Confirm that the chosen supplier provides traceable documentation for the component batch. Ensure compatibility with your reflow soldering profile specifications to maintain joint integrity. Check for any RoHS or REACH compliance declarations relevant to your target market regulations.

Selection Notes

Select this component when space constraints preclude through-hole mounting but higher reliability than thin-film chip resistors is required. Consider the thermal dissipation capabilities of the PCB layout to ensure the resistor operates within its safe working area. Evaluate the voltage coefficient and temperature coefficient of resistance if precision analog circuits are involved.

Part Context

This part falls within TE Connectivity's broad portfolio of passive discrete components. It complements other MELF-style resistors offering similar form factors but different electrical values. The series is engineered to meet stringent industry standards for durability and performance consistency across diverse manufacturing batches.

Replacement Considerations

Direct substitutes must match the physical footprint and electrical characteristics precisely. Verify equivalent resistance value, tolerance class, and maximum working voltage. Ensure the replacement component shares the same hermetic sealing technology to maintain environmental resilience levels comparable to the original specification.
