LEDs used for indicators on circuit boards have become one of today\'s most widely used lighting technologies. The WP934EB/2SRD LED is a model for such indicators, providing a reliable and low-cost option for user-friendly interface and simplified circuit boards. This article will explain the application field and working principle of the WP934EB/2SRD LED.

Application Field

The WP934EB/2SRD LED is ideal for indicators on circuit boards that require low voltage and a relatively small amount of input current. It can be used in most electronic circuits, as long as its maximum voltage rating is not exceeded. The WP934EB/2SRD is also suitable for use as an indicator on control panels and indicator boards due to its continuous diffused illumination with uniformly distributed light. Additionally, it is commonly used as an indicator in medical and instrumentation applications, safety systems, and other electronic equipment, providing a clear visual warning or status.

Working Principle

The WP934EB/2SRD LED is a 3-contact device that operates on direct current of up to 20 milliamps. This low-level current has a very low heat impact as compared to other indicators. The LED is mounted in a plastic housing that serves to both protect the LED from damage and allow it to evenly distribute light from its interior surface. The LED emits light when the direct current passes through the device. The light can be adjusted according to the current and is therefore well-suited for applications such as dimming and pulse-width modulation.

The WP934EB/2SRD LED has two ratings—forward and reverse voltage. The forward voltage rating is the minimum voltage necessary to cause the LED to emit light. The reverse voltage is the maximum voltage that can be applied to the LED before it is damaged. The forward voltage allows the current-limiting resistor to be set to the necessary value, ensuring the LED will only receive the required current.

In summary, the WP934EB/2SRD LED is a low-cost, low-power indicator that is suitable for a wide range of applications. Its low forward and reverse voltage requirements, coupled with its evenly distributed light and durable construction, make it a great choice for use on circuit boards or as an indicator or warning device.
