Designed for front- or real-panel mounting, Wilbrect LEDCO’s just released bipolar LEDs work directly off a 120- or 240-V ac line as an LED power indictor or as a drop-in replacement for neon ...

Long used in instruments and computers as visual indicators for signal integrity and operations status, LEDs are ideal choices due to their high reliability, low power use, and ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
