High Voltage MLC Capacitors
Application Information on High Voltage MLC Capacitors
High value, low leakage and small size are difficult parame-
ters to obtain in capacitors for high voltage systems. Olean
Advanced Products’ special high voltage MLC leaded
capacitors meet these performance characteristics. The
added advantage of these capacitors lies in special internal
design minimizing the electric field stresses within the MLC.
These special design criteria result in significant reduction of
partial discharge activity within the dielectric and having,
therefore, a major impact on long-term reliability of the prod-
uct. The high voltage radial capacitors are conformally coat-
ed with high insulation resistance, high dielectric strength
epoxy eliminating the possibility of arc flashover.
The high voltage radial MLC designs exhibit low ESRs at high
frequency. The same criteria governing the high voltage
design carries the added benefits of extremely low ESR in
relatively low (0.05 µF to 0.005 µF) capacitance and small
packages. These capacitors are designed and are ideally
suited for applications such as snubbers in high frequency
power converters, resonators in SMPS, and high voltage
coupling/DC blocking.
Also because these MLCs are designed for high voltage
applications, as input resonator capacitors they are well
safeguarded against transient requirements.
High voltage chips are available with voltage ratings greater
or equal to 600 volts in EIA standard sizes 1808 and larger.
