Additional Details

The QSDL-E114 is a red LED lamp typically packaged in a through-hole configuration for easy mounting on printed circuit boards. Key specifications include the forward voltage, forward current, luminous intensity, and viewing angle. The forward voltage is the voltage required to turn on the LED, while the forward current is the current required to achieve the specified luminous intensity. The luminous intensity is a measure of the brightness of the LED, and the viewing angle is the angle at which the LED's light output is visible. This LED is designed to operate within a specified temperature range, and proper heat sinking may be required for high-current applications. Agilent Technologies is a reputable manufacturer of LEDs, and the QSDL-E114 exemplifies their commitment to quality and reliability. Datasheets provide detailed information on electrical characteristics, performance graphs, and application guidelines, enabling designers to effectively integrate the LED into their circuits. A current limiting resistor is typically required in series with the LED to prevent damage from excessive current. The specific value of the resistor depends on the supply voltage and the forward voltage of the LED.
