Film capacitors are amongst the most versatile capacitors available in today’s market. They provide some of the widest array of application fields that can be found in any capacitor, ranging from low-voltage DC to relatively high-voltage AC applications. The ECW-H20122JVB is a perfect example of this type of device, and its capabilities can be explored through a brief description of its application field and working principle.

Application Field

The ECW-H20122JVB has a wide range of possible applications due to its very low voltage drop, extremely low rate of change of voltage with respect to time, and its linear response to frequency changes. Generally, it is suitable for all sorts of applications where an equilibrium between current density and power costs must be found. These applications range from the protection of delicate electronic components and circuits to providing a stabilizing counterbalance against surge voltages. Timing delay circuits, in very high speed switch mode power supplies, and lightening protection applications, also use the ECW-H20122JVB.

Working Principles

The working principle of the ECW-H20122JVB is based on its capacitance being made up of a number of layers of film, each independently polarized, stacked between two sets of plates (anode/cathode). The capacitance can be adjusted by changing the distance between each layer, or by changing the area of the plates. Due to the use of film, the insulation used is of a very high quality, thus enabling the ECW-H20122JVB to reach very high-voltage levels without exceeding its breakdown rating.

The film capacitors used in this device also have an inherently low self-inductance, which allows them to respond quickly to changes in voltage. This property is especially useful for high-speed applications, where a very fast rise time is required. By controlling this property, the ECW-H20122JVB can also be used to dampen current flow in order to reduce ripple in the power supply.

The ECW-H20122JVB is also able to maintain a very stable capacitance over a wide range of operating temperatures. This is because the film capacitors used in this device are manufactured with an extremely low temperature coefficient of capacitance. This means that the capacitance of the device does not change significantly with changes in temperature.

The relatively low cost of the ECW-H20122JVB also makes it an attractive device for many applications. In addition to its versatility and dependable performance, the ECW-H20122JVB is also very reliable, efficient, and has a low profile. This makes it the ideal choice for many applications where space is at a premium.

In conclusion, the ECW-H20122JVB is perfect for all sorts of applications where an equilibrium between current density and power costs must be found. Its wide ranging capabilities, low cost, and ease of use, make it an attractive choice for many application fields.
