Tantalum capacitors are components that store electric charge and are used across multiple applications. The M39003/03-0416H is a metallized tantalum chip capacitor featuring a reliable construction offering extended endurance and long life, making it a popular choice for designers working on applications that require reliable operation in extended service over time. This capacitor is especially well-suited for temperature-sensitive applications where size and weight matter.

The M39003/03-0416H is a polarized capacitor with an anodic termination and a cathodic termination. The polar design helps to ensure that the capacitor only works in the intended precise direction between the two terminations. The anode is typically identified by the black dot on the capacitor’s body.

The capacitance of this component is measured in picofarad, which is an SI measurement of electrical capacitance. The M39003/03-0416Hhas a capacitance of 4.7 μF, a working voltage of 25 VDC, and a temperature rating of 125°C. The maximum allowable ripple current is 7 mA while the maximum surge voltage can reach up to 50 VDC. The capacitor also features a low ESR at 125°C that is as low as 4.5 ohms, making it a good choice for high frequency power supplies, and has a high self-healing capability.

The M39003/03-0416H capacitor is ideal for use in consumer electronics, automotive components, medical devices, and other high-performance applications which require a reliable component. For example, it can be used in power converters, motor drives, audio systems, and other such tasks. The component achieves this by providing a reliable capacitance that can operate in extreme environmental conditions and is also resistant to many common solvents, making it suitable for applications with severe conditions.

The M39003/03-0416H offers high reliability, compact size, and good electrical and mechanical properties. It is constructed of a metallized tantalum film that is sandwiched between metallic electrodes and has a rugged and hermetically sealed package. This design ensures that it provides a reliable seal and resists vibration and shock. Additionally, this capacitor is RoHS compliant and meets stringent safety and environmental standards, making it an ideal choice for designers who are looking for an environmentally friendly component.

The working principle for the M39003/03-0416H is similar to all polar capacitors. When a direct current is applied to the capacitor, electric charge accumulates on one side of the capacitor due to the separation between the anode and cathode. This electric charge is then stored in the capacitance, and a potential difference is created between the anode and cathode. When the current is removed, the charge is effectively discharged and the potential difference is gone.

In summary, the M39003/03-0416H is an excellent choice for applications that require a reliable, small and environmental-friendly capacitor. Its superior construction, reliable performance, and low ESR combine to make it an ideal choice for a wide range of applications. Its working principle is similar to other polar capacitors, making it a reliable choice for designers working with temperature-sensitive applications.
