AVX Corporation, a leading manufacturer of passive components and interconnect solutions, is launching the evolution of its FFLC Series medium power film capacitors for DC filtering applications.
Available in large case sizes up to 35 liters, the new FFLC Series capacitors exhibit higher specific energy than equivalent solutions (up to 240J/l) and feature AVX’s controlled self-healing technology, which enables safe, high reliability, long lifetime performance with no risk of explosion. Also available with a low stray inductance option that enables high frequencyThe number of complete cycles or vibrations per unit of time. Rate of alternation in an AC current. Expressed in cycles per second or hertz (Hz). ripple currentThis applies to a DC application with a superimposed AC voltage. The ripple current rating is the maximum AC current the capacitor can handle., the series is ideal for DC filtering in any variety of power conversion applications, but is particularly well-suited for applications that require enhanced safetyClass X capacitors are used in “across-the-line” applications where their failure would not lead to electric shock. Class X safety caps are used between the “live” wires carrying the incoming AC current. In this position, a capacitor failure should not cause any electrical shock hazards, rather, a capacitor failure “between-the-lines” would usually cause a fuse or circuit breaker to open. and reliability, including: rail applications, such as main or auxiliary inverters; new energy applications, such as wind turbines and solar PV inverters; and industrial applications, such as motor drives.
“The combination of large case sizes, high specific energy, and controlled self-healing technology makes the next-generation of our fully-dry FFLC Series medium power film capacitors especially suitable for power converters in traction, drive, and renewable energy applications,” said Gilles Terzulli, worldwide marketing manager, power film capacitors, AVX. “Compliant with a number of rail, environmental, and fire standards, FFLC capacitors are extremely safe and reliable and can be customized to satisfy specific design criteria upon request.”
Comprised of metallized, segmented polypropylene film encased in unpainted, rectangular, resin-filled aluminum cases, FFLC Series capacitors feature two mounting brackets and either four M8/15 female connections or four M12/30 male connections. Voltage ratings for the series span 800V to 1350V, capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. values span 1750 micrfarad to 20,600 micrfarad, and parasitic inductance values span 32nH to 55nH. Exhibiting a ±10% tolerance, FFLC Series capacitors feature a maximum RMS current value of up to 400A and an average lifetime of 100,000 hours at rated DC voltage, 70 degrees C hot-spot temperature, and a less than 2 percent change in capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. value.
Lead time for the FFLC Series is in the range of 10-18 weeks and specific designs based on customer requests are available.
