Feed Through Capacitors W3F15C1028AT3A application field and working principle

Feed through capacitors are passive electrical components that may be used to filter, store, and couple signals and power supply lines in electronic circuits. The W3F15C1028AT3A is a type of feed through capacitor designed to provide signal filtering and coupling capability for high frequency communications and electronic applications. This capacitor features low inductance and a high level of ESD protection to ensure the signal integrity and circuit stability.

The W3F15C1028AT3A feed through capacitor is used in a variety of applications including modems, fax machines, and cellular phones, as well as other communication and electronic devices. In modems, it provides an interface for data signals between the receive and transmit stages. Fax machines and cellular phones require this capacitor for signal coupling between two stages while eliminating high frequency noise. Its ESD protection feature provides protection against electrostatic discharge, which is a huge issue for electronic devices.

Working Principle

At its core, a feed through capacitor consists of two capacitors – one ceramic and one metallized film – connected in series. The ceramic capacitor acts as a low pass filter that blocks any unwanted high frequency signals, whereas the metallized film capacitor retains the desired signal. The W3F15C1028AT3A capacitor also contains an ESD protection feature, which helps protect the device from external electrostatic discharge.

When signal needs to be sent from the input to the output of the device, the feed through capacitor will filter out any undesirable high frequency signals. This helps to ensure that only the clean, low frequency signal is sent to the output. Additionally, the ESD protection feature of the capacitor will protect the device from any external electrostatic discharges.

Conclusion

Feed through capacitors are a versatile solution for signal filtering and coupling in many electronic applications. The W3F15C1028AT3A feed through capacitor is designed with a low inductance and high level ESD protection, providing reliable performance for high frequency communication and other electronic devices. The feed through capacitor works by filtering out any unwanted high frequency signals and providing ESD protection to the device.
