Key Features
- Single red LED with clear lens delivering focused visible light output for panel indicator and status display applications
- Radial-mount through-hole package with 6.2 mm overall height for easy manual or automated PCB insertion
- RoHS-compliant (JESD-609 e1 rated) construction meeting current environmental and hazardous substance regulations
- Single-function configuration simplifying drive circuit design with standard 20 mA forward current and 2 V forward voltage
Applications
The SLR-342VC3F is commonly used as a status or fault indicator on industrial control panels, power supply boards, and consumer electronics where a bright red through-hole LED with a clear lens provides clear visual feedback at distances up to 5 m. Its radial-mount profile and 6.2 mm height make it ideal for front-panel PCB mounting in instrumentation, motor drives, and home appliances. The device also suits prototype and development boards for simple GPIO-driven LED indicators at 5 V or 3.3 V with a current-limiting resistor.

Frequently Asked Questions
What are the key electrical parameters of the SLR-342VC3F for drive circuit design?
The SLR-342VC3F is a single red LED typically requiring a forward voltage of approximately 2 V at a 20 mA forward current. For a 5 V supply, a series resistor of about 150 ohms limits the current to the rated 20 mA, while a 3.3 V supply requires approximately 65 ohms to achieve the same drive current.
How does the clear lens of the SLR-342VC3F affect viewing angle and brightness compared to diffused versions?
The clear lens of the SLR-342VC3F focuses light into a narrower beam angle — typically ±15 degrees half-angle — producing higher on-axis luminous intensity compared to diffused-lens LEDs. This makes it well suited for applications where the indicator must be visible from a specific direction at distances beyond 3 m, such as rack-mount equipment front panels.
What PCB mounting method does the SLR-342VC3F use and what are the installation requirements?
The SLR-342VC3F uses a radial-mount through-hole package with a 6.2 mm overall height and 2 leads spaced at standard 2.54 mm (100 mil) pitch. It is inserted into a PCB through-hole footprint and soldered using wave soldering or hand soldering — no SMT reflow is required — making it compatible with traditional through-hole assembly processes.
In which indicator and signaling applications is the SLR-342VC3F most commonly specified?
The SLR-342VC3F is most commonly used for power-on, fault, and status indicators on industrial control panels, embedded system boards, and consumer appliances. Its 6.2 mm tall radial-mount form factor allows panel cutout mounting where the LED protrudes through the panel for direct operator visibility in equipment racks, power supplies, and motor drives.
