CSL0901YT1

LED Indication - Discrete Overview

The CSL0901YT1 is a yellow surface-mount LED from ROHM Semiconductor, featuring a 587 nm dominant wavelength and 280 mcd luminous intensity. Packaged in a compact 0603 (1.6 x 0.8 mm) lens-type housing with a dome lens, it operates at a forward voltage of 2.1 V and a forward current of 20 mA. The component supports an operating temperature range of -40°C to +85°C and is available in reel or cut tape formats.

LED Indication - Discrete Feature Summary

• Utilizes a lens-type structure to enhance light output efficiency compared to standard flat packages.
• Features a raised light source position designed to minimize light leakage into adjacent areas.
• Constructed with silver-free chip technology to improve resistance to environmental degradation.

LED Indication - Discrete Applications

• Automotive instrument cluster indicators
• Home appliance status displays
• Office equipment indicator lights

LED Indication - Discrete Procurement Notes

Verify the specific suffix 'T1' against the official ROHM datasheet to confirm packaging configuration and moisture sensitivity level. Ensure the selected variant matches the required automotive grade if applicable, as standard and automotive versions may differ in reliability testing standards.

LED Indication - Discrete Selection Notes

Select this component for applications requiring high brightness within a minimal footprint. Consider the 0603 package size for space-constrained designs. Evaluate thermal management requirements given the power dissipation rating and ensure the driving circuit supports the specified 20 mA forward current limit.

LED Indication - Discrete Part Context

This part belongs to the CSL0901 series, which represents ROHM's line of small, high-output lens-type LEDs. The series is engineered to replace larger reflective LEDs, offering significant volume reduction while maintaining superior optical performance and reliability for demanding electronic applications.

LED Indication - Discrete Replacement Considerations

CSL0901WT1C serves as a verified equivalent within the same product family, sharing identical physical dimensions and electrical characteristics while differing primarily in emission color.
