Tantalum Capacitors

Tantalum capacitors are the most common form of surface-mount electrolytic capacitor in use today. They are composed of a tantalum cylinder coated with a dielectric material such as manganese dioxide and have an anode of conductive oxide-coated tantalum. They feature low equivalent series resistance (ESR) and excellent frequency characteristics, allowing them to be used in a wide variety of applications.

M39003/01-7244H Application Field and Working Principle

M39003/01-7244H Tantalum capacitors are a common form of surface-mount electrolytic capacitor used in the electronics industry. The M39003/01-7244H utilizes a tantalum/manganese dioxide anode coated with a conductive oxide. This type of capacitor has a low ESR, excellent frequency characteristics, and is stable over a wide temperature range. The M39003/01-7244H is ideal for use in applications such as motor control, audio filtering, and switching power supplies, and has a working temperature range of -55°C to +125°C.

The working principle of the M39003/01-7244H is relatively simple. When voltage is applied to the capacitor, current flows through an electrolyte between the tantalum anode and the manganese dioxide cathode. The current causes electrolytic reactions to occur, resulting in the formation of an insulating layer of oxide on the anode which prevents further current flow and enhances the capacitance. This oxide layer, formed from the electrolyte, is known as the dielectric. This dielectric is highly stable under temperature and voltage changes, allowing the capacitor to maintain a consistent capacitance and performance over a wide range of temperatures.

The M39003/01-7244H can be used in a variety of applications, such as motor control, audio filtering, and switching power supplies. With its low ESR and excellent frequency characteristics, it is especially well suited for use in audio and power supply circuits. In addition, the capacitor has a working temperature range of -55°C to +125°C, making it suitable for use in extreme temperature conditions.

Tantalum capacitors such as the M39003/01-7244H are a popular choice for use in electronic circuits due to their long life, low ESR, and excellent frequency characteristics. With its high temperature range and long life, the M39003/01-7244H makes an ideal choice for use in applications such as motor control, audio filtering, and switching power supplies.
