Test only applied in series equivalent circuit. 3) Voltage derating is applied at +125C. (The DCL parameter should be read after 5 minutes when it connected to the circuit). 1 TKT Tantalum CapacitorDipped Operating Voltage -55C to 85C 85C to 125C % Change in Working DC VR 67% of VR Voltage with Temperature Recommended Max 50% of VR 33% of VR Application Voltage Reverse Voltage Since tantalum capacitor has polarity, do not apply a reverse voltage to it. Do not apply capacitor to a circuit which only has alternating current. a) If there is no alternation, applying a low reverse voltage which is listed below to capacitor in a short time is approved. b) In principle, testing a circuit with tantalum capacitor or capacitor itself by using a resistor gear of millimeters in ignorance of polarity is forbidden. c) During measurement and application, if the tantalum capacitor is subjected to an undersirable reverse voltage due to carelessness, please dispose it, even if its electrical characteristics are still qualified. Temp. Max. Reverse voltage in a short time 25C 10% UR (rated voltage), working voltage to maximum of 1.0V. 85C 3% UR (rated voltage), working voltage to maximum of 0.5V. 125C 1% UR (rated voltage), working voltage to maximum of 0.1V. Ripple Voltage Please use the capacitor within permissible ripple voltage. a) The sum of DC bias voltage and the maximum AC branch voltage should not exceed rated voltage during operation. b) The sum of negative peak AC value and DC bias voltage should not exceed the specified reverse voltage. c) Ripple current applied to capacitor will generate active power loss, which will raise the rate of the failure caused by heat due to self-heat generation of capacitor. Therefore, ripple current and permissible power loss must be in control. Soldering Process Kingtronics tantalum capacitors are compatible with wave (single or dual), convection, IR, or vapor phase reflow techniques. Preheating of these components is recommended to avoid extreme thermal stress. Kingtronics recommended profile conditions for convection and IR reflow reflect the profile conditions of the IPC/J-STD-020D standard for moisture sensitivity testing. The devices can safely withstand a maximum of three reflow passes at these conditions. Hand soldering should be performed with care due to the difficulty in process control. If performed, care should be taken to avoid contact of the soldering iron to the molded case. The iron should be used to heat the solder pad, applying solder between the pad and the termination, until reflow occurs. Once reflow occurs, the iron should be removed immediately. Wiping the edges of a chip and heating the top surface is not recommended. During typical reflow operations, a slight darkening of the gold-colored epoxy may be observed. This slight darkening is normal and not harmful to the product. Marking permanency is not affected by this change.
