Aluminum Electrolytic Capacitors: EEV-HA1C221XP Application Field and Working Principle

Aluminum electrolytic capacitors are commonly used throughout different electronics and electric devices due to their large capacity and convenience. The EEV-HA1C221XP is unique to the aluminum electrolytic capacitors for its extended operating temperature and small size. This capacitor is able to be used in military and aerospace engineering operations since it withstands temperatures between -55°C to +125°C. It also has a much smaller size than the normal aluminum electrolytic capacitors.

Application Field

The EEV-HA1C221XP capacitor is ideal for use in various military and aerospace operations. This capacitor is also a good choice for filtering or decoupling of pulsed current applications. It is often used in harsh and challenging environments where extended temperature range products are needed. Additionally, it is suitable for a range of different military and aerospace applications, such as:

• Missile guidance systems
• Radars
• Telecommunications equipment
• High voltage applications
• UAVs and unmanned robotic systems
• Power electronics

The characteristics of the EEV-HA1C221XP capacitor includes a rated voltage of 4.7V, leakage current of 10uA maximum, and insulation resistance of 1000 megohms at 20 degrees Celsius. Furthermore, this capacitor also has a good ability to withstand extreme temperatures, a low impedance, and low ESR for the design and implementation of various applications.

Working Principle

The EEV-HA1C221XP capacitor is constructed with two aluminum foils that are rolled into a cylindrical shape. The two foils are sealed together with a non-conductive material that separates the two foils as well as acts as an insulator. An electrolyte liquid is then put in between the two aluminum foils. The two aluminum foils acts as the two plates of the capacitor, while the liquid electrolyte acts as the dielectric medium. The liquid electrolyte serves as the medium to store electrons which are later released. The amount of electrons released by the capacitor can be controlled by the capacitance value, which is determined by the distance between the two plates and its surface area. The capacitance value is a determinative factor in the amount of charge stored in the capacitor.

When a voltage is applied to the capacitor plates, electrons from the aluminum plates migrate to the electrolyte medium. This creates a buildup of negative ions which creates the charge across the plates. The liquid electrolyte helps maintain the balance of the charge and prevents the capacitor plates from discharging, thus creating a necessary electrical insulation between the two plates.

When a voltage is applied to the plates, a current is established between the plates and is discharged when the voltage is removed. This current increases with the increase of frequency until the capacitor reaches its maximum current load. The maximum amount of current the capacitor can handle depends on the capacitance value. The higher the capacitance value of the capacitor, the higher the current it can handle.

In conclusion, the EEV-HA1C221XP aluminum electrolytic capacitor is a unique capacitor for its compact size and extended temperature range. The capacitor is ideal for military and aerospace applications with its high capacitance value and low impedance. The construction and working principle of the capacitor is essential for proper understanding and implementation of the product’s capabilities. The EEV-HA1C221XP aluminum electrolytic capacitor is a remarkable capacitor for a wide range of applications.
