Preliminary
Multilayer Ceramic Capacitors that
Prohibit Surface Arc-over in High Voltage Applications
FEATURES
For this Worldwide Patent-Pending Technology
•
Surface-mountable, multilayer ceramic
RoHS
capacitors, that protect against surface arc-over
COMPLIANT
•
Higher capacitances and smaller case sizes
that save board space, as compared to standard high
voltage MLCCs
•
Voltage breakdowns are twice that of some competitor
products
•
Excellent reliability and high voltage performance
HVArcGuardTM Capacitor with no Surface Arc-over
Standard Capacitor with Surface Arc-over
APPLICATIONS
•
DC-to-DC converters (Buck and Boost)
•
Voltage multipliers for flyback converters
•
Lighting ballast circuits
•
Power Supplies
Insulation Resistance (IR):
At + 25 °C and rated voltage 100 000 MΩ minimum or
1000
ΩF
whichever is less.
At + 125 °C and rated voltage 10 000 MΩ minimum or
100
ΩF,
whichever is less.
Dielectric Withstanding Voltage (DWV):
This is the maximum voltage the capacitors are tested for a
1 to 5 second period, with charge/discharge current does not
exceed 50 mA.
250 Vdc: DWV at 200 % of rated voltage
500 Vdc: DWV at 150 % of rated voltage
630, 1000 Vdc: DWV at 120 % of rated voltage
