11-21UBC/C470/TR8

Overview

The 11-21UBC/C470/TR8 is a surface-mount infrared LED manufactured by Everlight Electronics Co., Ltd. It utilizes a 1206 package configuration with an integrated inner lens to direct optical output. The device emits light at a peak wavelength of 940 nm, which is standard for remote control and data communication applications. Key electrical parameters include a forward voltage of approximately 1.2 V and a maximum power dissipation rating of 130 mW. The component supports a continuous forward current of 20 mA and operates within a temperature range from -40°C to +85°C.

Feature Summary

• Incorporates an inner lens structure within the 1206 SMD package to optimize light emission directionality.
• Emits non-visible infrared radiation at 940 nm, ensuring compatibility with standard photodetectors.
• Designed for robust performance in consumer electronics and industrial data transmission environments.

Applications

• Infrared remote control transmitters
• Short-range wireless data communication modules
• Optical sensor interface circuits

Procurement Notes

Verify the specific suffix C470 against the manufacturer's official datasheet to confirm exact optical intensity and binning specifications. Ensure that the TR8 tape-and-reel packaging format aligns with automated assembly equipment requirements. Cross-reference the RoHS compliance status with the latest environmental declaration provided by Everlight Electronics Co., Ltd. prior to finalizing procurement orders.

Selection Notes

Select this component when a compact 1206 footprint is required for high-density PCB layouts. The 940 nm wavelength offers superior resistance to ambient visible light interference compared to other spectral ranges. Consider the 130 mW power dissipation limit when designing thermal management strategies for enclosed electronic enclosures or high-duty-cycle operation scenarios.
