Tantalum capacitors are an important type of electrochemical capacitor. They are used extensively within the electronics industry, and have been ever since they were invented in the early 1950s. The M39003/09-0317H is a specific type of tantalum capacitor that is especially designed for applications where high levels of frequency ripple are present, such as high frequency oscillators or pulse circuits. It is also well-suited for general purpose use and for situations where space is limited.

The M39003/09-0317H is an axial-leaded capacitor constructed of a tantalum anode and cathode, with an electrolytic dielectric material located between the two electrodes. The dielectric material is typically a manganese dioxide paste, and is encased in a metal casing. The capacitor is made from a manganese-carbon alloy that is both thermally and moisture resistant. This allows it to operate in high temperature and humid environments such as hot, arid climates.

The M39003/09-0317H has an important feature: its extremely low ESR (equivalent series resistance). ESR is crucial because it affects the performance of the capacitor, especially at higher frequencies. Lower ESR means higher capacitance and better performance in applications that require high frequency oscillation or pulse pulses.

The operating frequency of the M39003/09-0317H is up to 25kHz, where it has an exceptionally low voltage coefficient and temperature coefficient, giving it advantages in applications requiring frequent switching. The capacitor also features high insulation resistance and high capacitance stability, meaning that it can be used in applications dealing with varying voltages and temperatures. It also maintains its properties over the full military temperature range of -55C to +85C, ensuring reliable performance in a variety of temperatures and environments.

The working principle of the M39003/09-0317H is fairly simple. Its anode and cathode are connected to an external circuit and a voltage applied across them, resulting in a migration of charges. Depending on the polarity of the voltage, positive or negative charges will be attracted to the anode or cathode, respectively, creating a net electrical charge and resulting in a stored charge in the capacitor. When the voltage is reversed, the capacitor releases its stored electrical charges, discharging them back into the external circuit.

The M39003/09-0317H therefore has a variety of uses and is well-suited for circuit applications such as high frequency oscillators and pulse circuits, where the capacitor needs to perform reliably over a wide temperature range. Its low ESR and high insulation resistance make it well-suited for use in applications where space is limited and higher frequency ripple is expected.
