Overview
The ASMT-UWB1-NX3J2 is a high-power white LED from Broadcom Limited, featuring a PLCC-2 surface-mount package. It emits warm white light at a color temperature of 2700K with a luminous intensity of 2.3 cd (2300 mcd) at a forward current of 20 mA. The device has a typical forward voltage of 3.2 V and a power rating of 108 mW. It offers a 120-degree viewing angle and operates within a temperature range of -40°C to +85°C. Dimensions are 3.2 mm in length, 2.8 mm in width, and up to 2.1 mm in height.
Feature Summary
- Emits warm white light with a 2700K color temperature for soft illumination applications.
- Features a diffused yellow lens with a round flat shape to provide a wide 120-degree viewing angle.
- Constructed in a compact PLCC-2 SMD package suitable for space-constrained designs.
Applications
- Indicator lighting for consumer electronics devices
- Backlighting for small displays or keypads
- Ambient lighting in home automation systems
Procurement Notes
Verify the specific suffix against the official Broadcom datasheet to confirm the exact color temperature and binning requirements. Ensure that the ordering quantity matches the manufacturer's standard packaging specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) handling procedures during storage and assembly to maintain component integrity.
Selection Notes
Select this component when a warm white light source is required for indicator or low-level ambient lighting. The PLCC-2 form factor allows for easy integration into existing surface-mount layouts. Consider the 120-degree viewing angle for applications requiring broad light distribution rather than focused beams. Evaluate thermal management needs given the 108 mW power rating.
Part Context
This part belongs to the ASMT-UWB1 series of high-power LEDs manufactured by Broadcom Limited. The series utilizes a standardized PLCC-2 package available in various color temperatures. The UWB1 designation indicates a specific optical configuration with a diffused lens, distinguishing it from clear or focused variants within the broader LED portfolio.
Replacement Considerations
Cross-reference with other ASMT-UWB1 variants such as ASMT-UWB1-NX3G2 or ASMT-UWB1-NX3E2 if different color temperatures are acceptable. Verify mechanical footprint compatibility before substitution. Check electrical parameters like forward voltage and current ratings to ensure circuit compatibility.
