Feed Through Capacitors

Feed through capacitors are passive components that are widely used in packaged electronic devices, particular for circuit design involving RF signals. They serve to filter noise and stabilize impedances. The SFBLL5000222MX1 is an example of a feed through capacitor typically used in RF circuit applications.

Application Field of SFBLL5000222MX1

The SFBLL5000222MX1 is specially designed for high frequency applications in the range of 0.5 GHz-2.2 GHz in which noise-coupling and decoupling requirements are most significant. The SFBLL5000222MX1 consists of two capacitors inline connected in series, that is, a high frequency capacitor coupled with a low frequency capacitor in order to provide both high frequency and low frequency noise suppression. The low frequency capacitor serves to reduce common mode noise while the high frequency capacitor suppresses unwanted RF/MC noise.Generally, the SFBLL5000222MX1 is used to filter RF power and noise, and to minimize the inductive loop caused by the lead length and board size of the RF circuit. It is used in several applications, such as antenna feed cables, phased array systems, electromagnetic compatibility (EMC) filters, and differential filters. Some typical uses of the SFBLL5000222MX1 include:

• Antenna feed cable systems
• Phased array systems
• EMC filters
• Differential filter

Working Principle of SFBLL5000222MX1

The SFBLL5000222MX1 mainly consists of two ceramic capacitors connected in series, so it uses a two stage filtering operation to improve the decoupling and coupling between devices, helping them minimizing couplings and preventing interference.The low frequency capacitor acts as a filter for low frequency, which reduces common mode noise. The high frequency capacitor acts as a filter for high frequency, which suppresses unwanted RF/MC noise at high frequencies. The high and low frequency capacitors are connected in series with each other in order to form an inductive loop. The inductive loop helps to reduce inductive coupling, helping to increase the performance of the RF circuit.In addition, the SFBLL5000222MX1 is also designed to reduce electromagnetic interference (EMI) caused by noise coupling between devices, so that the device can still operate properly even in the presence of high levels of noise.

Conclusion

The SFBLL5000222MX1 feed through capacitor is a versatile component designed for high frequency applications from 0.5GHz to 2.2GHz. It consists of two capacitors connected in series to provide both high frequency and low frequency suppression. The low frequency capacitor reduces common mode noise while the high frequency capacitor suppresses unwanted RF/MC noise. Furthermore, the inductive loop helps reduce inductive coupling, thus improving the performance of the RF circuit. It is also used to reduce the amount of EMI caused by noise coupling between devices, allowing them to operate properly in the presence of high levels of noise.
