BN104K0473J--

Film capacitors, also known as film dielectric capacitors, plastic film capacitors, polyester or polypropylene capacitors, are passive electronic components used for storing electrical energy. The BN104K0473J is a film capacitor that is well-suited for applications in the power electronics, and motor drive control.

The key features of this film capacitor include 472µF capacitance, 470VDC rated voltage, and ±10% tolerance. The BN104K0473J is also resistant to high temperature and heavy-load conditions with an insulation resistance of 100MΩ and an operating temperature range of -40°C to +105°C. The capacitor operates with a wide range of frequencies and offers a low ESL. Additionally, this particularly robust capacitor image offers high reliability, is RoHS compliance and is UL recognized.

The primary purpose of the BN104K0473J is to reduce high frequency noise and smooth out power line ripple that can singly from power source. Consequently, the majority of the application field for the capacitor are in power electronics, motor drives and AV equipment where high power and voltage are applied.

The main operating principle of the BN104K0473J is to enable efficient storage of electrical energy to reduce the noise or ripple effects from high power and high frequency sources. The film capacitor works by holding a charge on two plates, separated by a thin dielectric foil. The foil serves as an insulator between the two plates, and thus negatively charged particles on one plate will not repel the positively charged particle on the other. Because of this, current can travel between the two plates, while the capacitor stores the energy, allowing powerful current surge to travel along the wires.

In addition, the BN104K0473J also provides a number of additional benefits. The capacitor can be used in both ac and dc circuits, and because it is relatively low impedance, it produces low levels of electrical loss. Moreover, the capacitor is smaller and lighter than other types of capacitors, which makes it an ideal choice for applications where space and weight are important considerations. The film capacitor also has a low equivalent series resistance (ESR), which is beneficial for applications that use high frequency switching.

In summary, the BN104K0473J is an ideal film capacitor for applications in power electronics, motor drive control, and other areas where high power and voltage are needed. The capacitor is also ideal for high frequency switching and is resistant to both temperature and heavy-load conditions. Its insulation resistance and operating temperature range also ensure that it can provide reliable operation in even the toughest environments.
