Feed Through Capacitors are any series mounted capacitors that can be used for various applications, such as filtering, blocking, coupling, decoupling, suppression, or grounding. PSM4-102M-15T0 is a specific type of feed through capacitor, which has a brief introduction of its application field and working principle.

Application Field

PSM4-102M-15T0 feed through capacitor is a general-purpose type capacitor especially designed for high-frequency industrial applications. It is especially applicable for AC/DC switching power supplies. This type of capacitor also has other common applications which include DC power supply, PDU and LED lighting. Moreover, it has a special feature which is suitability of RoHS-compliant.

Working Principle

The internal structure of PSM4-102M-15T0 feed through capacitor consists of a copper-clad core and two ceramic dielectrics. With the combination of ceramic dielectric and copper core, the PSM4-102M-15T0 has excellent high-frequency characteristics and low ESR. Additionally, the capacitor also has a robust design which helps to offer protection in adverse environments.

When in operation, PSM4-102M-15T0 provides a low-impedance path for alternating current (AC) and direct current (DC). This works by discharging the electrical current from one plate to the other and is done via “ionized” particles or atoms which accumulate on the surfaces of the metal plates as a result of the electrical current passing through the capacitor. This process is known as dielectric polarization, and it occurs when the capacitance between the plates varies proportional to the amount of current passing through it.

Due to the polarization of the capacitor, the current stored in the capacitor will slowly decrease over time. This is due to the fact that the electrical current is continuing to be discharged from one plate to the other and as the ions are released, the capacitance of the capacitor will decrease. The capacitance of the capacitor is restored once the plates are fully discharged, and the process of dielectric polarization will begin again.

Conclusion

PSM4-102M-15T0 feed through capacitor is a reliable and robust capacitor designed for high-frequency industrial applications. This type of capacitor is suitable for use in AC/DC switching power supplies, DC power supply, PDU, and LED lighting applications. With its low ESR and high-frequency characteristics, this type of capacitor is highly suitable for those demanding applications. The working principle of the capacitor involves dielectric polarization using the combination of ceramic dielectric and copper core, where electrical current is discharged from one plate to the other during the operation of the capacitor.
