Aluminum Electrolytic Capacitors have been integral fixtures of the greater electrical industry since their invention in 1933. The properties of Aluminum Electrolytic Capacitors have allowed a wide application of their use, extending to technological uses such as computers, aircraft, and spacecraft, as well as common uses such as amplifiers and general electronic applications like circuit boards and displays. Although they are generally well-suited for virtually any application, the more specialized Aluminum Electrolytic Capacitors, such as the EEV-HA1H3R3R, are especially crucial for more advanced and challenging applications. This article will further explore the EEV-HA1H3R3R Aluminum Electrolytic Capacitor, and its specific application field and working principle.

The EEV-HA1H3R3R is a radial-lead Aluminum Electrolytic Capacitor with an operating temperature range of -40°C to +105°C. It can be used in both automatic assembly and manual assembly machines, and fits into a 1206 surface-mount package. This smaller package provides a lower-profile installation with improved heat dissipation compared to the traditional aluminum electrolytic capacitors. It is also the first of the 6.3mm through-hole package to use a plastic collar, which eliminates the need for additional cutouts during automatic soldering.

The EEV-HA1H3R3R Aluminum Electrolytic Capacitor has a specific application field and working principle. It is designed to be used as a general purpose capacitor, meaning it can be used for any application where low-voltage and moderate-current capability are required. Its working principle is based on the electrochemical properties of an electrolyte solution and the internal resistance of an insulated aluminum conductor. In effect, an external electrical discharge causes capacitance to occur between two aluminum sheets with a special electrical insulator, called a dielectric, between them. This capacitance creates a storage unit for electrical energy, which can then be released as a charge.

One of the unique features of the EEV-HA1H3R3R is its ability to store large amounts of energy at a lower temperature compared to traditional aluminum electrolytic capacitors. This makes it a particularly good choice for high-temperature applications, where conventional aluminum electrolytic capacitors become less effective. Additionally, its low dielectric loss factor and greater insulation resistance enables the capacitor to be used at higher frequencies than traditional aluminum electrolytic capacitors. By utilizing the higher frequencies, the capacitor can store a greater amount of energy in less space.

Due to its small size and wide range of applications, the EEV-HA1H3R3R has become a popular choice for a variety of applications. It has been used in both digital and analog signal processing, where its low ESR and temperature coefficient make it an ideal choice for applications requiring high signal-to-noise ratio, low stray magnetic fields, and extremely low inductance. Additionally, its low internal impedance makes it an excellent choice for circuits requiring high power, high frequency switch mode power supplies, as well as motor and transformer applications.

In addition to its general-purpose applications, the EEV-HA1H3R3R is also suitable for specialized applications such as oscillators and timing circuits, telecom systems, instrumentation and control systems, and military alphanumeric displays. Due to its adjustable capacitance, it is also capable of handling a wide range of frequency requirements, making it well suited for power supplies, antenna and audio systems, as well as frequency synthesizers. This makes it ideal for applications that require precise speed and frequency control, such as solar arrays, photovoltaic cells, and industrial process controllers.

Overall, the EEV-HA1H3R3R is a high-performance aluminum electrolytic capacitor designed for a variety of applications ranging from general purpose use to specialized applications requiring a wide range of frequency requirements. Its low ESR and temperature coefficient make it an ideal choice for high signal-to-noise ratio circuits and applications requiring extremely low inductance, while its adjustable capacitance makes it suitable for power supplies and audio systems. Additionally, its smaller size and improved heat dissipation makes it an excellent choice for high-temperature applications and military alphanumeric displays. As such, the EEV-HA1H3R3R is an essential component in the greater electrical industry and beyond.
