HOW TO ORDER

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 con-
verters, 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 precautions be
taken in applying these chips in surface mount assemblies. This is due
to differences in the coefficient of thermal expansion (CTE) between the
substrate materials and chip capacitors. Apply heat at less than 4°C per
second during the preheat. Maximum preheat temperature must be
within 50°C of the soldering temperature. The solder temperature should
not exceed 230°C. 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.

Styles 1825, 2225, & 3640 are available with “N”, “L” or “J” leads as seen on page 9.
“V” denotes uncoated leaded units similar to SM0 product.
“W” denotes leaded epoxy coated units similar to SM5 product.
IE 1825AA103KAV00J would be uncoated leaded part with “J” style leads.
**Note: Style 1808 cannot have the marking oriented in tape & reel packaging due to square cross-section of chip.
Unmarked product is standard.
