Product Checklist
• Do you simulate capacitors?
• Do you use EDA tools to simulate your design?
Impedance always declining with increasing frequency.
Equivalent series resistance (ESR) of 0 ohms.
Equivalent series inductance (ESL) of 0 henries.
Has no self-resonance.
There are NO perfect capacitors.
The “Simple” RLC
•
•
•
•
Every capacitor has a parasitic resistance and inductance.
The impedance of a capacitor is complex with real (resistive) and imaginary (reactive) elements.
The impedance of a capacitor varies with frequency.
Every capacitor has a series-resonance frequency (SRF) where the inductive and capacitive
reactances cancel.
– Up to that frequency, the
capacitive element dominates
the reactance.
– Beyond that frequency, the
inductive element dominates
the reactance.
• In KEMET SPICE, the capacitance
and parasitics are given temperature
and frequency dependence, and with
the non-C0G ceramics, voltage dependence.
• The electrolytics are given RC ladder structures that account for capacitance roll-off
with increasing frequency.
KEMET NET List Files
The KEMET SPICE program has the capability to create ASCII files
