DIALIGHT Circuit Board Indicator LED, Through Hole, T-1 (3mm), 1.6 mcd - Yellow

The DIALIGHT Circuit Board Indicator is a high-precision, low-current LED component designed for demanding electronic applications. This 3mm T-1 form factor indicator is engineered for reliability and clarity, making it a critical component for status indication and system diagnostics.

Featuring a low forward current of 2mA, this indicator is energy-efficient and suitable for power-sensitive circuits. It emits a clear, visible light with a luminous intensity of 1.6 mcd and a standard 60° viewing angle, ensuring the status signal is easily discernible from various positions. The indicator is housed in a robust, high-contrast black housing rated UL94V-0 for flame retardancy, with a 31.5% Oxygen Index for enhanced safety and performance in specialised environments.

The through-hole mounting design ensures a secure and reliable connection to printed circuit boards (PCBs). Integrated housing stand-offs facilitate effective PCB cleaning post-solder, preventing flux contamination and ensuring long-term board integrity. The component meets stringent solderability standards per MIL-STD-202F, method 208F, guaranteeing consistent and reliable solder joints in manufacturing.

Key Specifications & Features:

• Low Current Operation: Efficient 2mA forward current minimises power draw.
• High Reliability Housing: UL94V-0 rated black housing with high oxygen index for safety.
• Design for Manufacturing: Housing stand-offs aid in PCB cleaning; meets MIL-STD solderability standards.
• Wide Compatibility: Designed to be compatible with industry-standard mounting blocks like the 551-xx07-004 QuadBlock for versatile integration.

This indicator is an ESD-sensitive device, so proper handling precautions are required during installation to prevent damage. Its combination of technical precision, robust construction, and compliance with high-reliability standards makes it an indispensable part
