SMPS Stacked MLC Capacitors
(SM Style) Technical Information on SMPS Capacitors
AVX is the original inventor of large capacitance value, stacked MLCC capacitors con-
structed with DIP leads. The SM-style, Switch Mode Power Supply (SMPS) capacitors
were introduced by AVX in 1980s. These capacitors are the closest to the ideal elec-
trical energy storage devices due to high CV product and extremely low ESR and ESL.
In addition to traditionally offered COG (Class I) and X7R (Class II) type dielectrics, AVX
introduces another class I, temperature compensated N1500 dielectric characterized
with very low dissipation factor. Thanks to considerably higher relative dielectric
constant of N1500 dielectric, the CV product is more than doubled in comparison to
ultra-stable COG dielectric, resulting in a significant reduction in the size of capacitor
and a significant improvement of volumetric efficiency.
The typical applications for different type dielectrics are:
COG: High frequency resonant capacitors, avionic AC line filters (400Hz to
800Hz), snubbers, timing circuits, high current repetitive discharge
N1500: Avionic AC line filters (400Hz to 800Hz), snubbers, high current repetitive
discharge, capacitive temperature compensation
X7R:
General filtering, input and output filters in DC/DC converters, bulk filters,
DC link capacitors, motor drive filters, high current non-repetitive discharge
Not RoHS Compliant
