Aluminum electrolytic capacitors (AECs) provide essential power and decoupling functions for a wide range of electronic equipment, from home appliances to high-end automotive and military systems. With increasing power density requirements and space constraints, there is a need for more reliable, robust, and efficient AECs. KY35VB151M8X11LL is one such AEC designed to meet this need.

Application Field

The KY35VB151M8X11LL aluminum electrolytic capacitor is a general purpose, non-polarized capacitor with long life expectancy and high performance. It is designed to replace standard AECs in medium duty applications. Common uses include actuating motors, controlling electric heaters, circuit timing, energy storage, energy conversion, and current limiting. For long-term use, KY35VB151M8X11LL AECs may also be employed as part of an electrical subsystem. Other potential applications include voltage-sensing, filtering and bypassing in industrial, telecommunications and automotive electronics.

Working Principle

The KY35VB151M8X11LL aluminum electrolytic capacitor is typically composed of three main components: aluminum foil cathode, paper separator, and aluminum Oxide Anode. Through electrochemical construction, a dielectric material is formed between the aluminum foil cathode and the aluminum oxide anode. This material provides high electrical insulation, which allows the capacitor to store a large amount of energy safely.

The capacitor also contains an electrolyte solution, which aids in setting the potential difference between the anode and cathode to specified levels. This creates a capacitive behavior in the circuit and allows for charge to build up on the electrodes. The capacitance of the capacitor depends on the total area of contact between the electrodes and the inter-electrode distance. In the case of the KY35VB151M8X11LL AEC, a maximum capacitance of 151µF (micro Farads) can be achieved under standard conditions.

When an AC voltage is applied to the KY35VB151M8X11LL AEC, the potential difference between the electrodes creates an electric field around the capacitor. This electric field induces charges of opposite polarity on the electrodes, allowing for positive and negative charge carriers to move and thus establish a current flow. The current flow is arrested by the capacitor and pushed back, giving the capacitor the ability to block AC currents.

Finally, the KY35VB151M8X11LL capacitor is designed to operate at temperatures ranging from -40°C to +85°C, making it an excellent choice for environmental protection applications. In addition, the capacitor is rated to have a long rated life of 2000 hours and a maximum leakage current of 5mA at +85°C and 2.5Vrms.

In conclusion, the KY35VB151M8X11LL AEC is a reliable, robust and efficient aluminum electrolytic capacitor ideal for a range of applications including motor actuation, electric heater control, circuit timing, energy storage and conversion, and voltage-sensing. The capacitor’s long-rated life and high capacitance make it an excellent choice for any power or decoupling application.
