Frequently Asked Questions
What luminous intensity does the KP-3216SYC produce, and how does it compare to standard-brightness yellow SMD LEDs?
The KP-3216SYC delivers a nominal luminous intensity of 150 mcd, which is significantly brighter than standard yellow LEDs that typically output 10 to 30 mcd. This high brightness makes it clearly visible in ambient indoor lighting conditions without requiring a high drive current, keeping power consumption low in battery-operated designs.
How does the 3.2 x 1.6 mm package size of the KP-3216SYC benefit compact PCB designs?
The 3.2 x 1.6 mm 0603-equivalent SMD footprint with a 1.1 mm profile allows the KP-3216SYC to fit in densely populated boards where through-hole or larger surface-mount LEDs would not. At a height of just 1.1 mm, it is also suitable for slim-form-factor products such as wearables and card-sized modules where vertical clearance is limited.
What forward current should be used to drive the KP-3216SYC reliably over its service life?
For long-term reliability, operate the KP-3216SYC at or below its 30 mA maximum forward current. A typical design target of 10 to 20 mA provides good brightness while reducing thermal stress and extending LED lifetime. Pair it with a current-limiting resistor calculated for your supply voltage, for example a 100-ohm resistor on a 5V rail gives approximately 20 mA drive current.
Can the KP-3216SYC be used in automotive or industrial applications requiring RoHS compliance?
Yes, the KP-3216SYC is fully RoHS-compliant and Pb-free, meeting the requirements of automotive and industrial manufacturing processes that prohibit lead in solder joints. Its -40°C to +85°C operating temperature range (typical for Kingbright SMD LEDs) supports standard industrial and automotive ambient temperature environments, though designers should verify the datasheet thermal limits for their specific application.
