Tantalum Capacitors

Tantalum capacitors are electronic devices which store energy in static electric field form which, in turn, can be released when needed or used. They are mostly used in consumer electronics and manufactured with various surface mount, through-hole or vertically mounted packages. Tantalum capacitors are usually used as filtering or bypass capacitors in designs which need to filter out high frequency signals while allowing lower frequency signals to pass.

M39003/01-2398/HSD

The M39003/01-2398/HSD is a high frequency surface mount tantalum capacitor featuring a minimum capacitance of 1.0μF and a maximum capacitance of 47μF. It is usually used in high frequency bypass or filter applications such as RF switching, linear or digital communications and power supplies. The capacitor has a Dissipation Factor (DF) of less than 0.1% AT 25°C and a typical Lead-playtime of 3.2ns. It is rated for operating temperatures between -55°C to 85°C. It has a voltage rating of 6.3V or higher, and a temperature coefficient (TC) of 470 PPM/°C.

Application Field

The M39003/01-2398/HSD tantalum capacitor can find application in many different fields, such as consumer electronics, communication equipment, computers, defense electronics and other related industries. It is suitable for filtering, bypass or decoupling applications which require stable capacitance over a wide temperature range. It is also suitable for RF frequency applications, due to its high dissipation factor and low lead times.

Working Principle

The M39003/01-2398/HSD tantalum capacitor operates on the same basic principle as all other capacitors. It stores electrical energy in electric field form when a voltage is applied to the two terminals of the device. The electrical energy will be released when the voltage is removed. The amount of energy stored is related to the capacitance of the device, which is determined by the materials used and the geometry of the device. The voltage rating of the device determines the maximum voltage which can be safely applied to it, while the temperature coefficient and dissipation factor control the capacitance stability with regard to temperature and power respectively.
