Rated for 1,000-5,000V and capacitance values spanning 100pF to 15µF, the RV series of DIP-leaded stacked SMPS capacitors has been released by AVX. The capacitors are available in three dielectrics: C0G, N1500 and X7R, and in six case sizes measuring 3.04-16.51mm in height. 

The RoHS-compliant devices are suitable for medical spectrometry and imaging equipment, semiconductor test equipment, power conversion and conditioning, motors and motor drives, high voltage SMPS and both commercial and industrial detection, scanning and quality analysis equipment.

The C0G capacitors feature a capacitance range spanning 100pF to 1.2µF and are available with capacitance tolerances of ±5%, ±10% or ±20%. The N1500 devices, which feature a capacitance range spanning 100pF to 1.9µF, are also available with capacitance tolerances of ±5%, ±10% or ±20%. Featuring a capacitance range spanning 100pF to 15µF, the X7R capacitors are available with capacitance tolerances of ±10%, ±20% or +80%, -20%. All versions operate across a temperature range of -55 to +125°C.

The RV capacitors can also be used on the AC input lines of AC/DC converters in the power supplies of spectrometers and ultrasound, CT and MRI equipment, as well as on the high voltage signal amplifiers between the transmitters and the ADC transducers in the same equipment. The devices are also suitable for use in commercial and industrial air, food and water quality analysis equipment, radiation detectors and the types of baggage- and body-scanning equipment employed by the US Department of Homeland Security. The capacitors can also 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.

“Many stacked SMPS capacitors for high voltage applications are not RoHS compliant, which limits the applications that they can be designed into. Our RV series stacked SMPS capacitors, which are both RoHS-compliant and designed for use in the 1,000-5,000V range, satisfy this gap in the marketplace and significantly expand the number and types of applications for which they are a suitable solution,” said Nic Billig, Product Manager, AVX.
