Tantalum capacitors feature high capacitance in relatively small packages, making them ideal for devices with limited space such as mobile devices or high-frequency digital clocks. This small size comes at a price, however: these devices are prone to failure under their rated voltage.

The M39003/09-4064/TR is a series of tantalum capacitors developed to address the issues related to traditional tantalum capacitors. The M39003/09-4064/TR features an advanced anode design, developed to reduce internal stress and extend the life expectancy of the device. It also has a lower self-heating rate over the rated voltage and frequency, reducing the risk of short-circuits. The M39003/09-4064/TR series also has improved input and output capacitance, which means that these devices can provide low-frequency performance similar to that of larger-sized tantalum capacitors without sacrificing performance.

The working principle behind the M39003/09-4064/TR series lies in their anode design. In traditional tantalum capacitor design, the anode is simply a coarsely-etched metal surface. The etching process creates sharp edges that concentrate electrical fields, resulting in increased flux leakage. The M39003/09-4064/TR uses a more advanced anode design that utilizes a “trench” structure to effectively conduct the applied voltage and reduce flux leakage. This “trench” structure increases the overall surface area, allowing for better heat dissipation and reduced self-heating rate.

The M39003/09-4064/TR is primarily used in applications where space is at a premium, such as in smartphones, tablets, and laptops. This series of capacitors is also ideal for use in high-frequency digital clocks, as the improved anode design allows for improved performance at higher frequencies. With its improved input and output capacitance and improved life expectancy, the M39003/09-4064/TR is an excellent choice for devices with limited space.

In conclusion, the M39003/09-4064/TR series of tantalum capacitors stands out among other tantalum capacitors due to its advanced anode design and improved input and output capacitance. Its reduced self-heating rate allows these capacitors to be used in applications with limited space, such as mobile devices and high-frequency digital clocks. The M39003/09-4064/TR is an excellent choice for these applications, as it offers improved life expectancy and superior performance.
