A new series of AEC-Q200-qualified, AC-line-rated ceramic disc 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. capacitors has been introduced by Vishay. The devices are designed to provide high reliability for Class X1 (440 VAC) and Y2 (300 VAC) automotive applications in accordance with IEC 60384-14.3, 3rd edition.
Featuring U2J, Y5S, and Y5U ceramic dielectrics, the AY2 series is optimized for on-board chargers and battery management in electric cars and plug-in hybrid electric vehicles (PHEV), as well as high-reliability industrial applications. The capacitors offer a 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. range from 10pF to 4700pF, with tolerances down to ± 10 % , over a temperature range of -55C to +125C.
The capacitors achieve an unmatched level of performance: they withstand more than 2,000 temperature cycles without a single failure, twice the AEC standard. With their superior robustness, the capacitors provide the highest levels of quality and reliability. They incorporate the latest in ceramic material, capacitor design, and production technologies.
The devices consist of a silver-plated ceramic disc with tinned copper connection leads offering 0.6mm diameters. AY2 capacitors are available with straight leads with spacing of 5mm, 7.5mm, and 10mm. RoHS-compliant and halogen-free, the devices’ encapsulation is made of flame-resistant epoxy resin in accordance with UL 94 V-0, says the company.
