Film capacitors are increasingly popular in applications today, owing to their reliability and wide array of features that make them suitable for a range of electrical devices and equipment. The 103MKP275KE is a type of film capacitor that has proven to be an efficient, reliable, and cost-effective choice for a variety of applications. This article discusses the application field and working principle of the 103MKP275KE.

Application Field of the 103MKP275KE

The 103MKP275KE is a metallized polypropylene film capacitor that is suitable for use in DC and AC applications. It is primarily used as a filtering device in power supplies, providing excellent filtering and noise suppression. It is also used for signal filtering in communications equipment, as well as for motor starting and lighting applications. The capacitor has a wide operating temperature range of -55°C to +125°C, making it particularly suitable for extreme-temperature environments.

The 103MKP275KE is UL 94-V1 rated and is typically used in applications that require high capacitance and high surge current. The capacitor has a wide capacitance range of 0.0056 to 2.2µF, making it suitable for use in a range of electronic devices. It is available in both leaded and surface mount configurations and is RoHS compliant.

Working Principle of the 103MKP275KE

Film capacitors, including the 103MKP275KE, are constructed with two sheets of metallized plastic, which are rolled together and sealed. When the capacitor is exposed to an electrical current, the two sheets act as two electrical plates, forming an electric field between them. The electric field then pulls electrons from one plate and pushes them onto the other. When the current stops, the electric field disappears, leaving the charges on the capacitor plates. This process is known as capacitance.

In terms of the 103MKP275KE, it has a very high tolerance for temperatures. Its structure guarantees a very low DF, low ESR, and low EMI emissions. The capacitance remains virtually constant over the wide temperature range and is largely immune to DC voltage bias. This makes the 103MKP275KE an efficient and reliable choice for a variety of applications.

Conclusion

The 103MKP275KE is a type of film capacitor that is designed for both DC and AC applications. It is primarily used as a filtering device in power supplies, providing excellent filtering and noise suppression. It has a wide capacitance range of 0.0056 to 2.2µF and a wide operating temperature range of -55°C to +125°C. The working principle of the 103MKP275KE is based on the same principles as other film capacitors -- two sheets of metallized plastic act as two electrical plates and form an electric field when exposed to an electrical current. The 103MKP275KE is an efficient, reliable, and cost-effective choice for a variety of applications.
