LTL-4252N

LED Indication - Discrete Overview

The LTL-4252N is a single-color yellow LED from Lite-On, housed in a T-1 (3 mm) through-hole package with a dome lens. It emits at a wavelength of 588 nm with a typical forward voltage of 2.1 V and a forward current of 10 mA. The component offers an optical intensity of 19 mcd and a viewing angle of 45 degrees. Rated for a power dissipation of 60 mW, it operates within a temperature range of -55 °C to +100 °C.

LED Indication - Discrete Feature Summary

• Features a transparent yellow dome lens for clear light transmission.
• Designed for standard through-hole mounting on printed circuit boards.
• Constructed with AlInGaP material for efficient yellow emission.

LED Indication - Discrete Applications

• Panel indicator lights
• General purpose status signaling
• Instrumentation displays

LED Indication - Discrete Procurement Notes

Verify the specific datasheet revision when sourcing, as parameters like forward voltage may vary slightly between manufacturing batches. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to final design approval. Ensure thermal management aligns with the 60 mW power rating during continuous operation.

LED Indication - Discrete Selection Notes

Select this component when a standard 3 mm yellow indicator is required for through-hole assembly. Compare the 19 mcd intensity against application visibility needs. Consider the 45-degree viewing angle for direct line-of-sight applications. Verify that the 2.1 V forward voltage matches the driving circuit logic levels.

LED Indication - Discrete Part Context

This part belongs to the LTL series of T-1 LEDs produced by Lite-On. The series includes various colors such as red, green, and amber, sharing similar mechanical dimensions. The LTL-4252N specifically provides the yellow variant within this standardized form factor, maintaining compatibility with existing board layouts designed for 3 mm lamps.

LED Indication - Discrete Replacement Considerations

Consult official Lite-On documentation for verified cross-references. Generic substitutes may differ in luminous intensity or spectral peak. Validate mechanical fit and electrical characteristics before implementation.
