What are the key features of LTL-4232?
- Single green LED with peak emission at approximately 565 nm wavelength and transparent lens for high-brightness indicator applications at 20 mA forward current
- Maximum forward current of 30 mA and maximum forward voltage of 2.6 V, compatible with direct drive from 3.3 V GPIO pins through a 68-ohm series resistor
- Standard T-1 3/4 (5 mm) through-hole package provides easy hand-soldering and breadboard prototyping, widely compatible with PCB footprints from every major CAD library
- REACH-compliant and JESD-609 e3 lead-free solder construction meets RoHS and environmental requirements for consumer and industrial electronics
What is LTL-4232 used for?
The LTL-4232 is used as a power-on or status indicator on front panels of consumer electronics, laboratory instruments, and industrial control boards where a clearly visible green LED signal at 20 mA is needed. Its 5 mm through-hole form factor makes it simple to mount in panel cutouts with press-fit bezels or PCB-edge indicators on prototype and low-volume boards. The transparent lens maximizes light output intensity for applications requiring visibility in brightly lit environments up to 2 meters from the LED.

Frequently Asked Questions
What series resistor value is needed to drive the LTL-4232 at 20 mA from a 5 V supply, and how does that change for a 3.3 V GPIO?
From a 5 V supply with a typical forward voltage of 2.2 V, the required series resistor is (5 V - 2.2 V) / 20 mA = 140 ohms; use a standard 150-ohm resistor. From a 3.3 V GPIO with the same 2.2 V forward drop, the resistor is (3.3 V - 2.2 V) / 20 mA = 55 ohms; use a 56-ohm resistor. Both calculations keep the LED below its 30 mA maximum forward current with adequate margin.
How does the LTL-4232 transparent lens affect viewing angle compared with a diffused-lens green LED of the same 5 mm package?
A transparent lens concentrates emitted light into a narrow approximately 30-degree half-angle beam, increasing on-axis intensity (typically 20 mcd to 50 mcd at 20 mA) but reducing off-axis visibility. A diffused lens spreads light over a wider 60-degree to 80-degree half-angle at lower peak intensity (typically 4 mcd to 10 mcd). The LTL-4232 transparent version is preferred for panel indicators viewed straight-on at 0.5 m to 2 m, while diffused LEDs suit displays requiring uniform appearance across a wide viewing arc.
What is the maximum reverse voltage the LTL-4232 can withstand, and when does that matter in an AC-driven indicator circuit?
The LTL-4232 has a maximum reverse voltage of 5 V, typical of standard low-power indicator LEDs. In AC-driven or relay-coil suppression circuits where the LED sees voltage transients above 5 V in the reverse direction, a series protection diode or a back-to-back LED configuration must be added. Without protection, even brief reverse spikes above 5 V can permanently degrade luminous intensity by damaging the LED junction, reducing output by 20% to 50% after repeated overvoltage events.
For a long-life industrial status panel running 24/7, how does continuous 20 mA drive affect the LTL-4232 rated lifetime?
Operating continuously at 20 mA, a standard green LED such as the LTL-4232 is typically rated for 50,000 hours of service before luminous intensity falls to 70% of initial output (L70 criterion). At 25°C ambient this equates to approximately 5.7 years of continuous 24/7 operation. Reducing drive current to 10 mA can extend L70 lifetime to over 100,000 hours (11+ years) with approximately 50% reduction in light output, which may still be sufficient for indoor panel indicator visibility in low-ambient-light environments.
