Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are an important form of capacitor created by combining aluminum with an electrolyte liquid, helping increase their ability to store energy. The UHW1C122MPD1TD is a high temperature radial polarized aluminum electrolytic capacitor, specially designed to have high temperature endurance and reliability for temperature ranges up to 105 degrees Celsius. The UHW1C122MPD1TD can operate in ranges up to +150V DC.

UHW1C122MPD1TD Application Field

The UHW1C122MPD1TD was primarily designed for use in automotive electronic systems, making it suitable for automotive applications such as airbags, ECUs, power steering, audio systems, and infotainment systems. The UHW1C122MPD1TD is also suitable for digital circuits, linear power supplies, and portable electronic devices.

UHW1C122MPD1TD Working Principle

Aluminum electrolytic capacitors use a layer of aluminum oxide to create an electrical insulation layer. The anode of the capacitor is the aluminum that has been treated to form an anodized layer, and the cathode is a simple piece of aluminum. The electrolyte liquid, usually an organic or aqueous electrolyte, is used to create an electrical current.When a voltage is applied to the aluminum electrode, the oxidation reaction between the electrolyte and the aluminum anode produces a glowing layer of aluminum oxide. The layer of aluminum oxide provides the electrical insulation layer and prevents leakage between the anode and the cathode. This oxidation process also increases the capacitor\'s ability to store energy with a much higher capacitance per unit volume than other non-electrolytic capacitors.The UHW1C122MPD1TD also features radial-leaded capacitors, which allow for a much larger surface area between the anode and the electrolyte, and thus a higher capacitance than axial-leaded capacitors. The UHW1C122MPD1TD is also designed to have full discharge and sealant construction, improving its durability and temperature resistance.

Conclusion

The UHW1C122MPD1TD is an aluminum electrolytic capacitor used for automotive electronic applications. With its radial-leaded design and full discharge and sealant construction, the UHW1C122MPD1TD is specifically designed to provide high capacitance, temperature resistance, and reliability, making it an ideal choice for automotive applications.
