Extended heat-resistant RGB LED product series

Würth Elektronik has expanded its 'WL-SFTW SMT Full-colour TOP LED Waterclear' product group. The new RGB LEDs, packaged in PLCC4 2121, PLCC4 3528, and PLCC6 3528, are characterised by excellent heat resistance. Their insensitivity to temperatures ranging from -40C to +100C makes them excellent solutions for reliable, colour-variable lighting in applications operating at high temperatures.

The operating temperature range of LEDs for industrial applications typically ranges up to just 85C. The company extends this range to 100C, opening up new fields of application. The unusually heat-resistant LEDs provide manufacturers of devices operating in hot or otherwise challenging environments with greater reliability. This includes industrial or automation solutions, street or outdoor lighting, as well as event and stage technology. Other applications are found in devices that are used very intensively, such as in the medical field, as well as energy-efficient lighting used in machine or server rooms.

The Waterclear lens ensures clear, brilliant colours and precise colour rendering. High-quality features such as silver-plated solder pads and heat-resistant PLCC housings ensure exceptional solderability, high resistance to thermal shock, and high reliability in production.

The LEDs are characterised by high light yield with low energy consumption, resulting in up to 15% higher efficiency than similar LEDs operating at elevated temperatures. They also have a longer service life thanks to the robust materials and improved temperature management.
