It is a high-frequency feed-through capacitor with a rated current of 2 A and an impedance of 220 pF. This article will discuss the application fields and working principles of B85121A2205A201 feed-through capacitors.

Application Fields of B85121A2205A201 Feed Through Capacitors

B85121A2205A201 feed through capacitors can be used in a wide range of applications, including communications, telecommunications, military, automotive, and medical equipment. They are also used for EMI/RFI filtering in power supplies, providing a high level of filtering capability at low cost. Additionally, the capacitors can be used for transient suppression, circuit stability, and RFID tagging in various applications.

Working Principle of B85121A2205A201 Feed Through Capacitors

The working principle of B85121A2205A201 feed through capacitors is based on their electrical properties. They are made of high quality capacitor material such as ceramic and polypropylene with a high working voltage. The high quality material ensures high insulation resistance, low capacitance and low leakage current.

The metal terminals of the B85121A2205A201 are connected directly to the input and output sides of the filter circuit. These terminals are designed with an extremely low inductance, which limits the high frequency signals from passing through the capacitor. At the same time, the low frequency signals pass through the capacitor without any attenuation. This ensures that signals such as radio waves, electromagnetic fields, and other forms of noise are filtered out while preserving the desired low frequency alternating current signals.

In addition to providing high frequency filtering, the B85121A2205A201 feed through capacitor also provides excellent transient suppression capability. This is achieved through its high capacitance and low impedance. This ensures that high frequency or impulse voltage surges are effectively kept out of a circuit while permitting the desired low frequency signals to pass through.

Conclusion

B85121A2205A201 feed through capacitors are highly versatile and reliable electronic components that can be used for a variety of applications. They are designed with a low inductance and high capacitance, ensuring a high level of filtering and transient suppression capability. Additionally, their low cost makes them an attractive option for a variety of applications.
