New RoHS-compliant series of high-voltage stacked SMPS capacitors
A new RoHS-compliant series of high-voltage DIP-leaded stacked SMPS
capacitors has been introduced by AVX. Rated for 1,000 to 5,000V and with
capacitance values spanning 100pF to 15µF, the new RV Series capacitors
feature low ESR and ESL, low DC leakage current, high current handling
capabilities, exceptional high-frequency performance and capacitance
retention with frequency.
Available in three dielectrics (C0G, N1500, and X7R) and six case sizes with
five maximum height dimensions spanning 0.120" to 0.650", the RV Series is
ideal for use in a broad range of high voltage applications, including:
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, says the company.
Commenting, Nic Billig, product manager, AVX, said: "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 stacked
SMPS capacitors, which are both RoHS-compliant and designed for use in the
1,000- to 5,000-volt range, satisfy this gap in the marketplace and
significantly expand the number and types of applications for which they're
an ideal solution."
In addition to the aforementioned applications, RV Series stacked SMPS
capacitors are well suited for use 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 analogue to digital converter transducers in that same
equipment. They are similarly well suited 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. Further, the versatile, RoHS
compliant RV Series 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.
C0G RV Series capacitors feature a capacitance range spanning 100pF to
1.2µF, and are available with capacitance tolerances of ±5%, ±10%, or ±20%.
N1500 RV Series capacitors feature a capacitance range spanning 100pF to
1.9µF, and are also available with capacitance tolerances of ±5%, ±10%, or
±20%. X7R RV Series capacitors feature a capacitance range spanning 100pF to
15µF, and are available with capacitance tolerances of ±10%, ±20%, or +80%,
-20%. Operating temperatures for the series spans -55C to +125C regardless
of dielectric, says the company.
