TANTALUM CAPACITORS General information MANUFACTURING Tantalum capacitors are, with ceramic, aluminum and film capacitors, one of the most used family. The manufacturing technology and the constant improvements in tantalum powders allow it to be the capacitor with the highest CV (product capacitance x voltage) per volume, very long life and high reliability. Tantalum capacitors are the capacitors which have the highest ratio of capacitance per volume. This is mainly due to the high dielectric coefficient of its insulator and to its large cross-section. It has also the following advantages: • Wide...

HERMETICALLY SEALED - TANTALUM CASES Electrical characteristics CAPACITANCE TOLERANCE (ON RATED CAPACITANCE) The capacitance is defined by a rated value (CR, indicated on the capacitor) and a tolerance (generally ±20%). It defines, with the rated capacitance, the range in which the capacitance value must be at room temperature. The capacitance is measured at a 100Hz or at a 120Hz frequency under a 0,1 to 1 VAC voltage and a 2,1 to 2,5 V bias (or 9 to 10 V for UR ≥ 100 V). At room temperature, it must be in the range defined by the rated value and the tolerance. Capacitance change vs temperature:...

HERMETICALLY SEALED - TANTALUM CASES Electrical characteristics DIRECT DC VOLTAGE LEAKAGE CURRENT The rated voltage (UR), indicated on the capacitor, is the maximum DC voltage which can be applied continuously between –55°C and +85°C. Leakage current is the residual current which flows through the capacitor after the charging time, under rated voltage. It is measured after a time not exceeding 5 minutes and is given in µA. For the types which can be used up to 125°C, the voltage must be derated between +85°C and +125°C according to the following curve. It is equivalent to the insulation resistance...

HERMETICALLY SEALED - TANTALUM CASES Electrical characteristics DISSIPATION FACTOR Dissipation factor is generally measured at the same time as the capacitance, with the same conditions. It is a function of the series resistance of the capacitor and the capacitance at low frequency. At low frequency, the series resistance is the sum of an ohmic part (leads, contacts, MnO2) and the dielectric losses. Dissipation factor is given in % and maximum limits are given for each type in the data sheets. EQUIVALENT SERIES RESISTANCE OR IMPEDANCE Equivalent circuit of a capacitor R: equivalent series resistance...

HERMETICALLY SEALED - TANTALUM CASES Electrical characteristics RELIABILITY Reliability of a component can be defined as its probability to work without any failure, in defined conditions and during a fixed time. Reliability is not therefore only a function of the component quality, but also of the application and environmental conditions. The parameter which is the most commonly used for the reliability is the failure rate in time, generally expressed in % per 1000 hours. CALCULATION OF A COMPONENT FAILURE RATE USED IN AN EQUIPMENT The calculation method on the next page uses parmeters which...
