Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, characterized by its relatively small size, a high capacitance-to-volume and weight ratio, and a long shelf life. They are constructed from a tantalum powder anode with the equivalent of a manganese dioxide cathode, and are typically housed in a cylindrical aluminum casing. Unlike other electrolytic capacitors, tantalum capacitors are not polarized and can be used either as a general-purpose capacitor or as a low-leakage capacitor. They are typically used in applications ranging from automotive, industrial to consumer electronics.

M39003/01-3135 Application Field and Working Principle

The M39003/01-3135 is a tantalum capacitor that is part of the T Series of Mil-Spec capacitors. It is available in 12 capacitance values ranging from 220nF to 22µF, with the capacitance tolerance of ±10%. The two main application fields for this model of tantalum capacitor are specialized military and commercial applications. It is frequently used in devices that require high-reliability, high-temperature operations such as satellites, radar systems, and computers.

The working principle of the M39003/01-3135 is the same as that of any other electrolytic capacitor. When a voltage is applied across the electrical contacts, it causes an ionic charge to flow between the two plates, resulting in a buildup of electrical charge. This charge, which is essentially stored energy, can then be released when the voltage is removed, allowing current to flow through the capacitor.

The M39003/01-3135 is an AEC-Q200 qualified capacitor, which means it meets industry standards for use in harsh environments. It also has a low leakage current and excellent vibration-resistance, making it suitable for military applications. Furthermore, it has a high-temperature operating range of -55°C to +125°C, which is wider than the typical operating range of most other tantalum capacitors.

The M39003/01-3135 is a reliable and cost-effective way to provide reliable electrical power in a variety of applications. Its small form factor and high temperature range make it an ideal choice for applications where space is at a premium or where the environment is extremely hot. Its long shelf life and low leakage current make it suitable for applications where the capacitor needs to remain functional over a long period of time.
