SM015A100JAN120 Datasheet, PDF (7/112 Pages) AVX Corporation – AVX Advanced Ceramic Capacitors for Power Supply, High Voltage and Tip and Ring Applications
SMPS Capacitors
Capacitor Performance
AC Ripple Capability
Due to the wide range of product offering in this catalog, the
AC ripple capabilities for switch mode power supply capacitors
and high voltage capacitors are provided in the form of IBM
compatible software package called SpiCalci. It is available
free from AVX and can be downloaded for free from AVX
website: www.avx.com.
SpiCalci program will provide answers to most of the design
engineers’ questions on critical parameters for their specific
applications:
• Equivalent Series Resistance
- function of frequency and temperature
• Equivalent Series Inductance
- function of design
• Self Resonant Frequency
ͱ f = 1/ (2 x π L x C)
• Thermal Characteristics
- function of design
• AC Ripple Capabilities
- function of frequency, temperature and design
