M39003/09-4042/HSD

Tantalum capacitors are type of electrolytic capacitor that utilizes a tantalum anode and a ceramic material as the dielectric. This type of capacitor achieves higher volumetric efficiency by using only a thin tantalum anode foil. It also requires smaller assembly as compared to other types of capacitors.

One of the very popular type of tantalum capacitor is the M39003/09-4042/HSD. It is specially designed for use in harsh environment and to cover for extreme temperatures. It is a surface mount, chip type of capacitor that is available in surface mount and through-stone version as well.

The M39003/09-4042/HSD has extremely small size of 1206, making it suitable for not only high-end, handheld electronic devices but also for high-temperature applications. Its small size, low parasitic inductance and minimized capacitor footprint are the main features that make it successful in steel and automotive industries.

The M39003/09-4042/HSD also has the ability to keep very low electrical leakage and ESR even in harsh environments. This characteristic is achieved by using a very thin dielectric film made of tantalum oxide. The dielectric films are sprayed onto the anode film and sealed against the environment through an epoxy coating.

The working principle of M39003/09-4042/HSD is based on the fact that when a capacitor is charged, it will absorb electrostatic energy and store it in a form of electric fields. This property is known as capacitance. When a voltage is applied across the terminals of the capacitor, a medium of material between the anode and the cathode will be polarized and separated electrostatic charges will be stored.

In order to achieve high performance and to extend the life of the device, the capacitance stability of the M39003/09-4042/HSD is also optimized. Its anode and cathode are made of special materials that offers low polarization delta and low leakage current, resulting in higher reliability. Its capacitance stability also offers improved shock and vibration resistance.

M39003/09-4042/HSD has a wide range of applications. It is mainly used in harsh environment applications such as aerospace, military, high-temperature, automotive, and portable electronic devices. It is suitable for applications with high current requirements or large capacitance and provides high temperature operation and is applicable in a wide range of temperature range between -55°C and 125°C.

To summarize, M39003/09-4042/HSD is a type of high-performance tantalum capacitor. It is notable for its very small size and its ability to maintain low electrical leakage and ESR even in harsh environments. Its anode and cathode are made of special materials to ensure higher reliability and capacitance stability. It also has a wide range of applications such as in aerospace, military, high-temperature, automotive, and portable electronic devices.
