Silver plated copper alloy leadframe termination system
Applications
Typical applications include switch mode power supplies (input
filters, resonators, tank circuits, snubber circuits, output filters),
high voltage coupling and DC blocking, voltage multiplier circuits,
DC/DC converters and coupling capacitors in Ćuk converters,
noise reduction (piezoelectric/mechanical), circuits with a direct
battery or power source connection, critical and safety relevant
circuits without (integrated) current limitation and any application
that is subject to high levels of board flexure or temperature
cycling. Markets include power supply, LCD fluorescent backlight
ballasts, HID lighting, telecom equipment, industrial and medical
equipment/control and Military.

Parameters/Characteristics
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1000 hours.
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and Dissipation Factor (DF) measured under the following conditions:
1kHz ± 50Hz and 1.0Vrms ± 0.2V if capacitance >100pF
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as Automatic
Level Control (ALC). The ALC feature should be switched to "ON".
