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. e.g.: Capacitance change vs temperature: see typical curves below. Maximum changes are given, for each type, on the data sheets. The standard tolerance for tantalum capacitors is 20%. CAPACITANCE CHANGE VS TEMPERATURE +30% Rated capacitance: 100µF Tolerance: 20% The measured capacitance must be between: 100 - (20% of 100) = 80µF and 100 + (20% of 100) = 120µF ±20% ±20% 1 C/C 0.8 ±20% 1.5 1.2 ±20% 2.2 1.8 ±20% 3.3 2.7 ±20% 4.7 3.9 6.8 5.6 8.2 +20% 0% –20% –40% –60% –80% –50 –30 –10 0 20 40 60 80 100 120 T (°C) www.exxelia.com 14 tantalum@exxelia.com Page revised 09/18 HERMETICALLY SEALED - TANTALUM CASES WET TANTALUM CAPACITORS 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 of the capacitor and it must be as low as possible. Maximum leakage current is a function of capacitance and rated voltage values and is given, for each type, in the data sheets.

The surge voltage is the maximum voltage which can be applied for short periods. It is given for each type in the data sheet and is generally equal to 1,15 times UR between –55°C and +85°C and 1,15 times UC at +125°C. Tests are performed with charging periods of 30 seconds, through a 1000 Ω resistor, and discharging periods of 5 min 30s. 1000 cycles are done. REVERSE VOLTAGE Capacitors in silver cases (CT4, CT4E, CT9, CT9E) and some in tantalum cases (WT83, WS83) cannot withstand any reverse voltage: it would cause damage, more or less rapidly depending upon the voltage value. It is therefore necessary to be sure that the bias voltage is high enough to avoid that the AC voltage creates a reverse voltage (negative peak). Other capacitors in tantalum cases (CT79, CT79E, ST79, DSCC 93026, M39006/22 and M39006/25) can withstand a reverse voltage as specified in the individual datasheet. www.exxelia.com 15 tantalum@exxelia.com Page revised 09/18 WET TANTALUM CAPACITORS HERMETICALLY SEALED - TANTALUM CASES Electrical characteristics DISSIPATION FACTOR ESR CHANGE VS TEMPERATURE Dissipation factor is generally measured at the same time as the capacitance, with the same conditions.

The parameter which is the most commonly used for the reliability is the failure rate in time, generally expressed in % per 1000 hours.

ANODE AND INSULATOR 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 range of capacitance (less than 1µF to more than 10 000µF) • Wide operating temperature range (–55°C to +200°C) • Electrical characteristics stable with temperature • Low leakage current • Very low ESR for some types • Stability after long periods of storage , without any reforming The basic raw material is a high purity (greater than 99,99%) tantalum powder with a very fine granulation, compressed to form a cylinder or a parallelipiped constituting the anode of the capacitor (positive plate). The pellet is then sintered at high temperature (1200°C to 2200°C), under high vacuum (10–6 Torr), firstly to purify the powder and secondly to obtain a strong mechanical structure by a welding of the particles. All these characteristics allow tantalum capacitors to be commonly used either in large volume markets like mobile phones or computers, or in specific High-Rel applications such as space, aerospace and military. The insulating part is obtained by anodization to a depth of the tantalum surface which forms a tantalum pentoxide film (Ta2O5) with a thickness of about 16 angstroms per anodization volt. The dielectric coefficient is between 21 and 27 depending upon the anodization conditions. Its main uses are found in the following functions: • Filtering • RC time constant • Bypass • Energy storage • Coupling Tantalum capacitors can be divided into two main families and several subfamilies: Solid tantalum capacitors: • Solid MnO2 - Metal cases - Molded cases - SMD WET ELECTROLYTE: CATHODE AND ENCAPSULATION In this case, the cathode is formed by a sulphuric acid solution. The anodized tantalum pellet is impregnated with this solution and then placed in a silver or tantalum case, into which some equivalent gelled solution have been previously deposited. Wet tantalum capacitors: • Silver cases • Tantalum cases The case is then crimped on the internal PTFE gasket to make the sealing. The final steps are welding (CT79), soldering (CT9) or elastomer seal (CT4) depending on the capacitors. SOLID ELECTROLYTE: CATHODE AND ENCAPSULATION • Solid Polymer - SMD In this case, the cathode is formed either by managanous dioxide which is a grey semi conductor or by polymer solution. HOW TO USE THE SELECTION GUIDE Solid MnO2 cathode is obtained by dipping the pellets into a manganous nitrate water solution which impregnates the internal structure; this solution is then decomposed in a high temperature oven to obtain manganous dioxide. This operation is repeated several times. The nature and quality of this semiconductor are important to some of the electrical parameters (especially the serial resistance). 1 - The Technical Selection Guide can be used to select a product according to the main technical requirements. 2 - The Classification according to specification makes the link between all major standard specifications and the products. 3 - The Selection Guide by family has the same classification as in the catalogue. You will find for each type the main features, the approvals and the page number of the technical data sheet. To finish the negative plate, a graphite coating and then a silver coating are deposited on the outside surface of the manganous dioxide or conducting polymer. The positive nickel lead is welded on the tantalum wire and the negative lead is either soldered for the products with axial leads or glued with a silver epoxy for the SMD range. BURN-IN - SORTING - INSPECTION All the products are submitted to a final burn-in, with differing severities depending upon the characteristics of each type (temperature, voltage, duration). Then follows the sorting, marking and inspection operations. It can be noted that the procedures for these operations are the same for approved and non approved parts (except the periodical tests). www.exxelia.com 4 tantalum@exxelia.com Page revised 09/18 TANTALUM CAPACITORS General information TYPE IDENTIFICATION - ORDERING INFORMATION CECC SPECIFICATIONS THE COMPLETE IDENTIFICATION OF A PRODUCT IS MADE OF Some of the products which are described in this catalogue are made to a CECC specification; these documents give in detail the following information for each type: • The climatic, electrical and mechanical characteristics • The test and inspection procedures • The sampling methods and levels • The tests periods • The type (or model) • The case size • The rated capacitance • The tolerance • The rated voltage • If applicable the CECC specification number THE TYPE It can be expressed with the commercial description (CTC21E C 33µF 10% 40V) or the EXXELIA part number (TS22EC336K040F).
