Film capacitors are energy storage components made of organic or inorganic film as the medium. These capacitors can be used in the widest range of applications, such as power electronic equipment, motor drives, audio equipment, electronic circuits, and RF communication equipment. The ECH-U1H151JB5 is a part of this broad film capacitor family.

Applications

The ECH-U1H151JB5 is well-adapted for industrial equipment and automotive applications due to its high dielectric strength and low ESR in comparison to other film capacitors. This capacitor has a polyethylene terephthalate film, which has excellent voltage characteristics up to 500V at 60Hz. This part can also be used for AC and DC applications, where the capacitance range is between 0.15μF to 47μF. Its relatively broad working temperature range of -55°C through +85°C further solidifies its position in these two application areas.

Benefits

Unlike other film capacitor models, the ECH-U1H151JB5 provides superior benefits due to its unique design. The presence of a self-healing property in this component allows it to let low level transients pass through, thereby eliminating potential safety issues. Additionally, this part has excellent current capacity for handling voltage spikes and higher dV/dt values. It is also designed to withstand harsh environments more efficiently than its counterparts. Its size is also much smaller when compared with electrolytic capacitors, making it easier to use in compact circuits where space is a concern.

Working Principle

Film capacitors, such as the ECH-U1H151JB5, work when electrical energy is stored in a dielectric medium’s electric field created by the electrodes. This voltage difference develops electric charges on the electrodes due to their electric field. When a capacitor reaches its capacitance value, the charge is transferred to the other side, forming a closed loop. The amount of electricity that can be stored in a capacitor is referred to as its energy density.

Conclusion

In short, the ECH-U1H151JB5 is an excellent piece of film capacitor engineering from Nichicon. This component provides excellent voltage characteristics up to 500V at 60 Hz for AC and DC applications. Its self-healing property eliminates potential safety issues, while its relatively broad working temperature range makes this part particularly useful for industrial equipment and automotive applications. Its overall size and performance also make it a great choice for any circuit.
