High voltage stacked SMPS capacitors are RoHS-compliant

February 10, 2015 // By Graham Prophet
AVX has an RoHS-compliant series of high voltage, DIP-leaded stacked SMPS capacitors, rated for 1,000–5,000V and with capacitance values spanning 100pF to 15µF.

The RV Series capacitors feature low ESR and ESL, low DC leakage current, high current handling capabilities, high frequency performance, and exceptional capacitance retention with frequency. Available in three dielectrics (C0G, N1500, and X7R) and six case sizes with five maximum height dimensions spanning 0.120 in. to 0.650in., the RV Series is intended for use in a broad range of high voltage applications

“Many stacked SMPS capacitors for high voltage applications aren’t RoHS compliant, which limits the applications that they can be designed into. Our new RV Series.... satisfy this gap in the marketplace and significantly expand the number and types of applications for which they’re an ideal solution,” said Nic Billig, Product Manager at AVX.

These capacitors are also suited for use on the AC input lines of AC/DC converters in power supplies; they may be used as I/O filtering and bulk storage capacitors in high voltage SMPS, as DC blocking capacitors, as DC link capacitors in AC/AC and DC/AC motor drive inverters, as power conditioning capacitors in DC/DC and AC/DC converters, and as start-and-run capacitors in AC induction motors.

C0G RV Series capacitors feature a capacitance range spanning 100 pF to 1.2 µF, and are available with capacitance tolerances of ±5%, ±10%, or ±20%. N1500 RV Series capacitors feature a capacitance range spanning 100 pF to 1.9 µF, and are also available with capacitance tolerances of ±5%, ±10%, or ±20%. X7R RV Series capacitors feature a capacitance range spanning 100 pF to 15 µF, and are available with capacitance tolerances of ±10%, ±20%, or +80%, -20%. Operating temperatures for the series span -55°C to +125°C regardless of dielectric.
