Overview

The 546 Oval 5mm Blue LED is a compact, high-brightness LED designed for applications requiring clear and noticeable blue illumination. Its oval lens shape provides a broader light distribution than many standard round LEDs, making it useful for indicators, displays, control panels, and decorative electronics.

Operating at a typical forward current of 20mA, this LED is specified with a forward voltage of approximately 3.2–3.4V and a blue emission wavelength of 460–465nm. Similar 546 oval blue LEDs are commonly available in the 460–470nm range with through-hole construction.

The through-hole DIP construction makes installation straightforward on PCBs, perfboards, breadboards, and custom electronic assemblies. The oval lens and wide viewing angle are particularly useful where the LED needs to remain visible from different directions.

How to Use

Connect the LED with the correct polarity and use an appropriate current-limiting resistor. For a typical 5V circuit, a resistor should be selected based on the LED's forward voltage and desired operating current.

The LED should not be connected directly to a voltage source without current limiting, as excessive current can permanently damage the LED.
