Aluminum – Polymer Capacitors and PLV1V390MDL1: Application Field and Working Principle

Aluminum-polymer capacitors are one of the most efficient ways to store and regulate electrical energy in our electronic devices today. This technology encompasses both capacitors and resistors and has become increasingly popular for applications including decoupling, snubber, and buffering. The PLV1V390MDL1 is a great example of this capacitor type, as it has many benefits and applications, combining high capacitance with low ESR and ESL values.

Overview of Aluminum – Polymer Capacitors

Aluminum-polymer capacitors, sometimes referred to as hybrid capacitors, are a type of capacitor that features an anode composed of aluminum foil embedded with a dielectric and a separator containing a liquid or gel electrolyte. This combination gives it superior voltage handling characteristics, high capacitance density, low ESR (Equivalent Series Resistance), and long life. The dielectric and a separator also contain a variety of additives to enhance performance.

The capacitance of an aluminum-polymer capacitor is proportional to the surface area of the aluminum foil, the applied voltage, and the dielectric material used. The use of liquid or gel electrolyte has the added advantage of reversible electrochemical reactions, providing a constant capacitance with temperature, power cycling, and frequency.

Aluminum-polymer capacitors are ideal for decoupling, snubber, buffering, as well used for power back-up applications. As a result, aluminum-polymer capacitors are used in applications such as PC motherboards, HDD power supplies, consumer electronic devices, automotive electronics, telecoms and more.

PLV1V390MDL1: Application Field and Working Principle

The PLV1V390MDL1 aluminum-polymer capacitor is a multilayer device in a single SMD (Surface Mount Device) package. The device has a rated voltage of 1V and a capacitance value of 390mF. With a maximum leak current of 0.40mA and a tolerance of -20% to +50%, the PLV1V390MDL1 is ideal for many different applications.

The PLV1V390MDL1 is commonly used as an Uninterruptible Power Supply (UPS) to maintain power during an outage, or as an EMI filter for reducing spikes, noise, and interference. It also makes a great snubber due to its high capacitance and low ESR characteristics, which are great for dampening voltage and current surges.

The PLV1V390MDL1 has many additional features, such as excellent frequency characteristics, a low profile design, high capacitance and ESR stability, and RoHS compliance. These features make the device ideal for a wide variety of applications, from consumer electronics and communication devices to industrial applications and more.

The working principle of the PLV1V390MDL1 is similar to that of other aluminum-polymer capacitors. The anode is made up of an aluminum foil embedded with a separator containing a dielectric material and a liquid or gel electrolyte. When voltage is applied, the positive ions flow through the electrolyte, creating a capacitance between the anode and the negative terminal. This allows the current to be stored within the capacitor and then released as needed.

Conclusion

The PLV1V390MDL1 is a great example of the power and efficiency of aluminum-polymer capacitors. This multilayer device has a rated voltage of 1V and a capacitance value of 390mF, making it ideal for many applications, from consumer electronics to industrial applications. The device also has a low profile design, high capacitance and ESR stability, and RoHS compliance, making it a great choice for a variety of applications.
