Tantalum capacitors are a type of electrolytic capacitor. They are composed of two electrodes – an anode and a cathode – with a conductive electrolyte providing the medium for ion transfer between the electrodes. The electrodes are typically made of tantalum or aluminum, with the anode being a high-purity dielectric oxide film deposited on the electrolyte. The oxide film provides the largest capacitance per unit volume and allows a high current density. A key feature of tantalum capacitors is their extremely low leakage current, which is a function of the thickness of the oxide film.

M39003/01-5644 is a type of tantalum capacitor developed for use in extreme temperature and/or vibration applications. It features a conductive glass-to-metal feedthrough, a conformal coating for additional moisture and corrosion protection, and a low internal resistance. The sealed construction makes it ideal for high temperature applications, and the external leads are designed to remain mechanically secure in high vibration environments.

The M39003/01-5644 capacitors work on the same principle as other types of electrolytic capacitors. A high voltage is applied to the device to attract electrons from the anodic surface. The electric field generated within the capacitor causes the electrons to flow from the anode surface to the cathode surface, creating an electric field – the polarization of the capacitor’s dielectric layer. The polarizing effect of the electric field enables the device to store energy as an electrostatic charge.

The M39003/01-5644 capacitors have a wide range of applications. They are ideally suited for use in automotive, electronic, high frequency, and medical applications. In automotive applications, they can be used for storing energy in circuits which require a high degree of reliability, such as for engine control, antilock braking, and airbag systems. In other applications, they can be used for power supply filtering, controlling power spikes, and providing input capacitance for switching power supplies and VDSL modems.

The M39003/01-5644 capacitors also provide high temperature stability, low ESR, high ripple current, and a wide capacitance range. They can withstand temperatures ranging from -55 to +125 C, with an operating temperature range of -55 to +85 C. This makes them ideal for use in applications that require durability and reliability in extreme temperatures and harsh environments. In addition, they are highly reliable and have a long service life.

Overall, the M39003/01-5644 capacitors are a reliable and durable solution for extreme temperature and/or vibration applications. They offer a wide range of capacitance values and a low ESR, providing a high degree of reliability and a long service life that is ideal for uses in automotive, electronic, high frequency, and medical applications. In addition, their tight sealing provides added protection against moisture and corrosion.
