Tantalum Capacitor News II

by: hkcapacitor   Keywords: Tantalum, Capacitor

Tantalum Capacitor has strict demand on storage conditions.  The Storing period is 10 years after manufacturing., in principle (excluding solderability).

In order to assure use, tantalum capacitors stored for over two years or processedthrough dipping molten solder prior to using preferably applied rated voltage while inherent resistance of the power supply is not more than 3Ω(For Non-solidtantalum capacitor, connect a protection resistor of 1100Ω max., in series to the capacitor), and withstand aging at 85℃ for 4-8 hours, then make measurement. The lead terminals of non-polar tantalum capacitor are reversed once every onehour and measurement of DC leakage current is also conducted on the two lead terminals respectively.
Store the Tantalum Capacitor in the package not to be exposed to direct sunlight and dust. Store in the environment holding ordinary temperature (-10~+40℃) and ordinary humidity (80%R.H. or under).If left in the atmosphere of high temperature and high humidity for a long time, solderability of the terminals is decreased and performance of the capacitors is lowered.
