Introduction

The F1199DD20 is a type of Power Line Filter Modules. It is designed to reduce high-frequency interference from the power lines and ensure reliable operation of electrical and electronic devices.

Application Fields

The F1199DD20 Power Line Filter Modules are widely used in a variety of applications where it is required to reduce high-frequency interference from the power lines. These include communication systems, industrial control systems, medical devices, automotive electronics, and home appliances.

In addition to providing protection against high-frequency interference, the F1199DD20 Power Line Filter Modules can also be used to eliminate ground loops and transient voltages caused by switching between multiple power sources.

The F1199DD20 Power Line Filter Modules can also be used to reduce EMI/RFI emissions from electrical and electronic components. This reduces the risk of radio interference from the device itself and helps to meet the requirements of applicable international safety and EMC standards.

Working Principle

The F1199DD20 Power Line Filter Modules consist of two components: an inductive filter and a switching element. The switching element is used to switch between two positions, allowing the filter to be used as either an on-Time filter or an off-Time filter, depending on the requirements.

In the On-Time position, the inductor in the filter eliminates high frequency interference before it has a chance to enter the device. The Off-Time position allows the filter to be bypassed allowing the device to receive its full power supply.

The F1199DD20 Power Line Filter Modules also feature a built-in Ferrite element that provides additional filtering for low-frequency interference. This improves the overall effectiveness of the filter module and ensures that the device is protected from all types of interference.

Conclusion

The F1199DD20 Power Line Filter Modules are a reliable and effective way to reduce high-frequency interference from the power lines. They are widely used in a variety of applications and can also be used to eliminate ground loops and transient voltages caused by switching between multiple power sources. The built-in Ferrite element provides additional filtering for low-frequency interference, ensuring that the device is protected from all types of interference.
