Summary

Würth Elektronik 15404094BA470 is selected in LED Emitters - Infrared, UV, Visible category when brightness/color and thermal behavior need to remain consistent over time. Key specs include Description (WL-SISW SMT INFRARED SIDEVIEW LE), Temperature (-40°C ~ 85°C), Package/case (0402 (1005 Metric)), and Mounting (Surface Mount).

Selection Notes
  • For 15404094BA470, verify the supply current (50mA) under your operating conditions and modes.
  • Confirm the emission wavelength (940nm) is compatible with your optical path.
  • Confirm the operating temperature range (-40°C ~ 85°C) meets your deployment conditions.
Alternates & Substitutions
  • For LED Emitters - Infrared, UV, Visible, validate alternates under worst-case corners rather than assuming typical-only conditions represent production builds.
  • Validate the min/max operating conditions (temperature -40°C ~ 85°C) and keep headroom for worst-case corners.
  • Lock the mechanical constraints first (package/case 0402 (1005 Metric), mounting Surface Mount, packaging Tape & Reel (TR), Cut Tape (CT)) before comparing performance specs.
  • For LEDs/displays, align wavelength 940nm and validate visibility under your ambient light and viewing angle.

Application Scenarios

When Würth Elektronik 15404094BA470 is used in LED Emitters - Infrared, UV, Visible designs, teams typically start by confirming interfaces, supply rails, operating envelope, and qualification expectations. For isolated links, propagation delay, CTR, and dv/dt immunity matter; for indicators, visibility under ambient light and consistent brightness are key. Well-integrated optoelectronics improve user feedback, sensing robustness, and noise immunity in real products. LED indication design balances forward voltage/current, brightness, and viewing angle so visibility remains consistent under ambient light and temperature. In real deployments, at scale, the winner is often the option that is easiest to qualify and least sensitive to small layout and process differences. In outdoor equipment, UV exposure and moisture drive sealing and derating choices for optical components. This keeps the design closer to the datasheet boundaries and farther from fragile, layout-dependent behavior.

Compatibility Advice
  • For production stability, validate CTR or optical transfer behavior across temperature and aging so margins remain stable over life. This keeps integration from depending on typical-only conditions.
Project Fit
  • Less ideal when integrating Würth Elektronik 15404094BA470 for LED Emitters - Infrared, UV, Visible, mechanical integration is uncertain, making optical assumptions difficult to reproduce, because the integration depends on constraints that cannot be controlled across builds.
