Feed Through Capacitors have a variety of uses, especially when it comes to protecting electronic components from surge currents and interference. The SBSMC5000472MXR is a unique capacitor utilized for protection from transient effects. This article will discuss the application field and working principle of this capacitor.

Applications

The SBSMC5000472MXR is a pass-through capacitor designed to protect against transient suppression. It can be used in a variety of applications where surge protection and interference protection are desired. Specifically, the SBSMC5000472MXR is used in low-voltage circuits and when interference is an issue, allowing the system to maintain an acceptable signal-to-noise ratio. Passive electronics such as RF diversity antennas, audio amplifiers, and filter circuits all benefit from the capacitor’s transient protection capabilities.

Principle of Operation

The SBSMC5000472MXR utilizes a metallized polypropylene film dielectric material. This is sandwiched between two over-current protected coated copper plates. The plates are placed in a plastic housing to ensure safe passage of high voltages. The capacitor has two PCB-mounted pins, one for input and one for output. These pins create a direct passage from the input to the output.

When a and b are connected, the metallized polypropylene dielectric material begins to accumulate a charge. This is due to the capacitance of the material that is created between the two plates. A voltage can then be applied across the plates that will cause a current to flow through the dielectric material creating a principle of capacitive power flow away from the load. This is how a pass-through capacitor works to protect against transient suppression and shield from interference.

Conclusion

The SBSMC5000472MXR is an effective capacitor used for protecting electronic components from transient effects and interference. It is a pass-through capacitor with two PCB-mounted pins to create a direct passage from input to output. It utilizes a metallized polypropylene dielectric material that accumulates a charge when input and output are connected. The capacitance of the material creates a principle of capacitive power flow away from the load. This enables it to protect from transient suppression and interference.
