Overview
The LTST-C19MGEBK-JA is a surface-mount device (SMD) LED component designed for high-density electronic applications. As part of the Lite-On LED series, it offers consistent performance with industry-standard dimensions (typically 0603 or similar package size). These LEDs are commonly used in professional electronics manufacturing due to their reliability and compatibility with automated pick-and-place processes. The "BK" in the part number typically indicates a black package, which helps improve contrast in display applications.
Structure and Working Principle
The LTST-C19MGEBK-JA consists of a semiconductor chip mounted on a leadframe and encapsulated in a plastic package. When forward voltage is applied (typically 2.0-3.2V), electrons recombine with electron holes in the semiconductor, releasing energy in the form of photons. The package includes a molded lens that shapes the light output, with the "JA" suffix often indicating specific optical characteristics. The component features anode and cathode terminals for surface mounting to printed circuit boards, following standard SMD soldering processes.
Key Features
This LED series offers several technical advantages for industrial applications. The components typically provide high luminous intensity (often 20-50 mcd) with low forward current requirements (2-5 mA), making them energy-efficient. The black epoxy package minimizes light bleed between adjacent components in dense arrays. These LEDs maintain stable performance across a wide temperature range (-40°C to +85°C is common), suitable for automotive and industrial environments. The RoHS-compliant construction ensures environmental compliance for global markets.
Application Areas
The LTST-C19MGEBK-JA finds extensive use across multiple industries. In consumer electronics, it serves as status indicators on appliances and backlighting for control panels. Automotive applications include dashboard illumination and switch position indicators. Industrial equipment manufacturers utilize these LEDs for machine status displays and control system interfaces. Their reliability makes them suitable for medical device indicators where consistent performance is critical. The components are also integrated into IoT devices and smart home systems for visual feedback.
Maintenance and Precautions
Proper handling ensures optimal performance and longevity of LTST-C19MGEBK-JA LEDs. Avoid exposing components to excessive heat during soldering (peak temperature typically below 260°C for 10 seconds maximum). ESD precautions should be followed during handling and installation. When cleaning PCB assemblies, use methods compatible with plastic encapsulated components. For long-term storage, maintain original packaging in controlled environments (temperature <40°C, humidity <60% RH).
B2B Procurement Guide
When sourcing LTST-C19MGEBK-JA LEDs, verify manufacturer authenticity through authorized distributors. Request current datasheets as specifications may be updated. Minimum order quantities typically range from 1,000-10,000 pieces for standard pricing. Consider ordering sample quantities for testing before large purchases. Lead times vary from stock availability to 8-12 weeks for custom orders. For high-volume requirements (50,000+ units), negotiate pricing and confirm production schedules with suppliers.
