IN-S42DS5B

LED Indication - Discrete Overview

The IN-S42DS5B is a single-color surface-mount LED manufactured by Inolux, designed for indication applications. It features a blue light emission with a peak wavelength of 472 nm and a forward voltage of 2.8 V at a forward current of 5 mA. The component utilizes a 0402 (1005 metric) package with dimensions of 1.0 mm in length, 0.55 mm in width, and 0.3 mm in height. It offers a viewing angle of 145 degrees and emits an intensity of 28.5 mcd. The device operates within a temperature range of -30°C to +85°C and includes moisture sensitivity protection.

LED Indication - Discrete Feature Summary

• Side-view configuration for visibility on PCBs
• Compact 0402 surface-mount footprint
• High viewing angle for broad illumination

LED Indication - Discrete Applications

• Electronic device status indication
• Panel indicator lights
• Consumer electronics signaling

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version for the IN-S42DS5B to confirm RoHS compliance details and humidity sensitivity classification before integration. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as specified by the manufacturer's official documentation. Cross-reference the electrical parameters against your circuit design requirements to ensure compatibility with standard drive voltages.

LED Indication - Discrete Selection Notes

Select this component when a low-profile side-view LED is required for space-constrained designs. The 0402 package allows for high-density mounting, while the 145-degree viewing angle ensures visibility from various positions. Consider the 2.8 V forward voltage drop when designing the current-limiting resistor network to maintain optimal brightness without exceeding the 5 mA maximum forward current rating.

LED Indication - Discrete Part Context

This part belongs to Inolux's standard SMD LED series, which provides a range of discrete lighting solutions for general indication purposes. The IN-S42DS5B specifically addresses the need for compact, reliable blue indicators in modern electronic assemblies. It complements other components in the manufacturer's portfolio by offering standardized dimensions and electrical characteristics suitable for mass production environments.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other 0402 blue LEDs with similar 472 nm wavelengths and 2.8 V forward voltages. Verify mechanical compatibility with the 1.0 x 0.55 x 0.3 mm footprint and ensure the replacement part supports the same 145-degree viewing angle and side-view orientation for proper assembly alignment.
