Tantalum Capacitors

Tantalum capacitors are a type of capacitors made of tantalum that exhibit excellent electrical characteristics, such as high capacitance-to-voltage (CV) ratio, high stability, and low-meltdown threshold.

The M39003/01-5497/HSD is a surface mount tantalum chip capacitor manufactured by United Chemi-Con. This part is available in three capacitance values: 1 uF, 2.2 uF and 3.3 uF. The temperature range is from -55°C to +125°C, and the operating voltage is up to 16 V.

Application Fields

Tantalum capacitor products, such as the M39003/01-5497/HSD, are popularly used in mobile communication devices, digital cameras, computer application boards, network switches, and automotive industries. A tantalum capacitor is used as a passive electrical component, which can filter out noise, smoothen electrical signals, and keep power steady when device is running.

As a reliable, efficient and low-cost solution provider, M39003 series tantalum capacitors offer a wide range of surface mount applications. Their small size, low cost, and stable performance make them an ideal choice for various circuit designs.

Working Principle

Tantalum capacitors use the principle of the Ohio effect. It is widely utilized in the capacitors because of its high capacitance-to-voltage ratio. In a tantalum capacitor, tantalum powder is contained in an electrolytic solution, which is sealed inside a ceramic or plastic-encased package. A dielectric oxide layer is formed between the two electrodes when applying a voltage, enabling the capacitor to store electrical energy in the form of a charge.

To ensure the quality of its capacitance performance, a surface mount tantalum capacitor (such as the M39003/01-5497/HSD) is conditioned in an oven before it is released to its customer. The conditioning process involves heating the chip to a specific temperature and holding it at that temperature for a predetermined amount of time, thereby allowing the part to reach its optimum capacitance value.

The M39003 series of tantalum capacitors offer excellent electrical characteristics and high-temperature stability. These features make it an ideal choice for various applications, such as decoupling, filtering, and pulse bypass in mobile communication devices, digital cameras, automotive systems, and industrial equipment.
