N1500 High-Voltage Capacitors Take Up Less Board Space

Tue, 12/18/2012 - 10:20am

AVX Corporation has added an N1500 super dielectric option to its high-voltage, multilayer ceramic (MLC), radial leaded capacitor series.  An extension of the SV Series, the new N1500 super dielectric capacitors take up less board space and offer higher capacitance values than comparable C0G dielectric capacitors and are ideally suited for applications including snubbers in high-frequency power converters, resonators in SMPS, AC line filtering, and high-voltage coupling/DC blocking. 

“High value, low leakage, and small size are difficult parameters to obtain in capacitors for high-voltage systems, but our SV Series MLC radial leaded capacitors feature a special internal design that minimizes the electric field stresses within the MLC,” said Dan Shields, North American product manager at AVX.  “This results in a significant reduction of the partial discharge activity within the dielectric, has a major impact on the long-term reliability of the product, and allows us to meet all of these performance characteristics.” 

AVX’s high-voltage SV Series MLC radial leaded capacitors are coated with high insulation resistance and high dielectric strength epoxy, which eliminates the possibility of arc flashover.  The series also exhibits low ESRs at high frequencies.

The new N1500 dielectric SV Series capacitors feature a capacitance range of 100pF to 0.47µF with tolerances of ±5%, ±10%, and 20%, a voltage range of 600-5000V, and a maximum dissipation factor of 0.15%.  The operating temperature range for the series is   -55°C to +125°C.  Additionally, a Hi-Rel screening option (100% Group A testing per MIL-PRF-49467) is available. 

The performance of switch mode power supply (SMPS) capacitors can be simulated by downloading the newly updated SpiCALCI 7.0 engineering tool at http://www.avx.com/SpiApps/default.asp#spicalci.  Custom values, ratings, and configurations are also available. 

All parts are priced upon request, and lead time is 11-14 weeks.
