Furthermore, long life time is realized by high temperature & moisture resistance using originally developed exterior material. This series is ideal for filtering for xEV applications and industrial power supplies.
Moisture is the most common cause for the failures in electronic components. These failures are related to moisture induced corrosion, the popcorn effect, delamination, ion migration, tin whisker growth, etc. All these failure mechanisms can take place in solid Tantalum (Ta) capacitors with either inorganic manganese dioxide cathode (Ta/MnO 2
Table 1: Classification of Class- X Safety Capacitors. Class-Y Capacitor: Class-Y safety capacitors are connected from the line conductors to ground, and they help filter out high-frequency noise, spikes, and transients that can be conducted back onto the power lines. Y capacitors in EMI filters help to suppress common mode EMI, which occurs when unwanted

ECQUA is a new X2 safety capacitor and offers a guaranteed moisture resistance of 85˚C, 85%, 500h under loaded conditions. The special fuse function of the patterned metallisation leads to a very stable capacitance level over the capacitor lifetime and thus guarantees a high reliability of your application. ECQUA is accredited in accordance
Lower humidity resistance allows moisture to enter the capacitor, which in turn can shorten the capacitor''s lifespan. As such, there is a need to improve the case and filler resin of encased film capacitors. 1) To this end, we developed the new MKCP4T series of capacitors that use thinner dielectric film, as well as a new outer case and epoxy resin. These adaptations allow MKCP4T

Capacitors designed for use in applications where failure may pose a risk to the safety of persons or property (typically those involving AC line voltages) are designated with an alphanumeric safety rating, such as X1, X2, Y1, Y2, etc., according to regulatory standards. "X" rated devices are certified for applications where failure is not expected to pose a shock

All safety capacitors are approved according to IEC 60384-14.4, UL, and CQC, while all series are compliant with RoHS and the REACH regulations. Vishay’s line of X1 / Y2 and X2 surface-mount safety capacitors offers devices for operating voltages up to 250 VAC. As surface-mount devices, the capacitors simplify circuit board assembly.
Safety capacitors are also called EMI / RFI suppression capacitors, AC line filter safety capacitors, or X- and Y-rated capacitors. X and Y capacitors not only keep radio frequency noise generated by the device local to that device, but also protect the device from mains noise and high voltage surges.
