UV LED selection starts with wavelength and risk
Start by identifying what the number describes: an absolute limit, recommended operation, bin boundary or typical test result.

Nichia NCSU434B — UV LEDs. Selection notes: Identify wavelength, radiant output, drive conditions and optical materials.
Read the conditions, not just the number.
This is an editorial profile of published manufacturer data, not an independent measurement. Values belong to the named model or family and the conditions shown in the parameter table. Consult the source revision and full ordering code before design approval.
| Parameter | Value | Basis | Conditions / source |
|---|---|---|---|
| Body / footprint width | 3.5 mm | nominal | Manufacturer mechanical outline; nominal dimensions. ↗ |
| Body / footprint length | 3.5 mm | nominal | Manufacturer mechanical outline; nominal dimensions. ↗ |
| Peak wavelength | 280 nm | typical | Manufacturer announcement: UV-C peak wavelength. ↗ |
| Radiant flux | 62 mW | typical | Manufacturer announcement at 350 mA; verify complete datasheet and thermal conditions. ↗ |
| Characterization current | 0.35 A | specified | Current associated with the announced typical radiant output. ↗ |
Identify wavelength, radiant output, drive conditions and optical materials. Do not convert UV output to visible lumens or infer a safe exposure time from electrical power. UV systems require a competent optical-radiation risk assessment, protective enclosure and appropriate interlocks; this site does not provide exposure or treatment approval.

Selection notes
Identify wavelength, radiant output, drive conditions and optical materials. Do not convert UV output to visible lumens or infer a safe exposure time from electrical power. UV systems require a competent optical-radiation risk assessment, protective enclosure and appropriate interlocks; this site does not provide exposure or treatment approval.
Evidence and limits
An omitted parameter is unknown here, not zero. Typical, minimum and maximum values are not interchangeable. A family profile is not an exact electrical configuration and does not automatically qualify for the driver selector.
