Manufacturer:XILINX Description:High value, low leakage and small size are difficult parameters to obtain in capacitors for high voltage systems. AVX special high voltage MLC chips capacitors meet these performance characteristics and are designed for applications such as snubbers in high frequency power converters, resonators in SMPS, and high voltage coupling/DC blocking. These high voltage chip designs exhibit low ESRs at high frequencies. Larger physical sizes than normally encountered chips are used to make high voltage chips. These larger sizes require that special pre- cautions be taken in applying these chips in surface mount assem- blies. This is due to differences in the coefficient of thermal expansion (CTE) between the substrate materials and chip capacitors. Apply heat at less than 4C per second during the preheat. Maximum preheat temperature must be within 50C of the soldering temperature. The solder temperature should not exceed 230C. Chips 1808 and larger to use reflow soldering only. Capacitors with X7R Dielectrics are not intended for AC line filtering applications. Contact plant for recommendations. Capacitors may require protective surface coating to prevent external arcing. |
