Tantalum capacitors are a type of capacitor which uses tantalum as an anode. This form of capacitor is popular due to several advantages over other capacitor technologies such as ceramic capacitors. They have a fairly high tolerance to high temperatures, as well as a superior volumetric efficiency.

M39003/01-2818/TR is a tantalum capacitor designed to operate at temperatures ranging from -65 to +125 degrees Celsius. This particular model has a tantalum solid anode and a wound, resin-molded tantalum oxide cathode. The anode is hermetically sealed with a welded wire and tantalum case, while the cathode is a dissolvable anode with a glass, melt-in-jacket technology. The capacitor has a voltage rating of up to 50V with a temperature coefficient of +22 PPM/deg C and a tolerance of ±10%. It has a capacitance range between 10 to 470 µF.

The application field of M39003/01-2818/TR tantalum capacitor is primarily in high-reliability circuits and applications which require high temperature performance, such as automotive, aerospace, and aviation. The capacitor is also useful in defense aerospace, computer and telecom applications, as well as medical devices and instrumentation.

The working principle of M39003/01-2818/TR tantalum capacitor is based on the principle that when a metal oxide is polarized, it develops a nonlinear relationship between voltage and electrostatic capacitance. In this capacitor, the anode is made of tantalum which has a desirable nonlinear capacitance-voltage relationship and a high dielectric constant. The capacitor has a glass outer coating, which acts as a barrier to prevent charge leakage between the anode and cathode. When a voltage is applied to the anode, it absorbs the charge and polarizes the oxide layer, resulting in a change in capacitor capacitance. The capacitor also employs a self-healing mechanism, whereby if the capacitor is damaged due to over voltage or over temperature, the oxide layer automatically forms around the existing oxide layer and reduces the current leak. This basic principle of operation explains how the capacitor works in a wide variety of applications.

M39003/01-2818/TR tantalum capacitor is a reliable and efficient capacitor which is suitable for a wide range of applications due to its temperature tolerance and volumetric efficiency. Its ability to self-heal makes it an ideal choice for high-reliability circuits and industries seeking a sturdy and reliable electronic component. As such, the M39003/01-2818/TR tantalum capacitor is an ideal choice for a wide range of application requirements.
