Dialight 551-0307F Yellow LED Circuit Board Indicator, 3mm, Through Hole
Buy Dialight 551-0307F yellow LED circuit board indicator. 3mm, through hole, 10mA, 6.3mcd. Ideal for signalling.
The Dialight 551-0307F is a compact, right-angle 3mm LED circuit board indicator featuring a single housing. This component is designed to form horizontal LED arrays when multiple units are mounted on 4.45mm centrelines, enabling efficient and space-saving board layouts.
The indicator uses a standard efficiency LED with a tinted, diffused lens, producing a clear yellow light with high contrast. The black housing is UL94V-0 flame-rated and constructed from PBT polymer with a 31.5% oxygen index, offering reliable thermal and fire resistance for demanding applications. Integral housing standoffs facilitate thorough PCB cleaning after soldering, and solderability complies with MIL-STD-202F, method 208F for dependable connections.
The component is compatible with the 551-xx07-004 quad block for flexible system integration. The LED is safe for direct viewing per IEC 825-1 and EN-60825-1 standards. With a forward current of 10mA, luminous intensity of 6.3mcd, and a 45° viewing angle, this indicator delivers consistent and visible signalling in various electronic systems.
