Vishay Semiconductors VLHW490 is a high-intensity white LED from Vishay that emits light with a high color rendering index. The typical color temperature is 5500 K and the emission range is 3 mm. Applications include indicators, backlights, indoor and outdoor signboards, incandescent lamp replacements, and marker lights.
The VLHW490 is a 3 mm T1 water‑clear package white LED using InGaN technology. It delivers high luminous intensity with typical chromaticity coordinates x = 0.33, y = 0.33 and a color temperature of 5500 K. The chip is embedded in an elastic resin for improved robustness against temperature cycling.
Typical applications include indicator and backlighting, indoor/outdoor message panels, marker lights and as an alternative to incandescent lamps. The device is RoHS compliant, lead‑free and features an ESD‑withstand voltage up to 1 kV.
