Capacitor model, selection, capacitance calculation and PCB layout and wiring Capacitor model, selection, capacitance calculation and PCB layout and wiring. Capacitors usually have two parasitic parameters: equivalent series resistance (ESR) and equivalent series inductance (ESL). The ESL of decoupling capacitors is caused by the current flowing inside. Using multiple decoupling capacitors in parallel can reduce the impact of capacitor ESL, and placing two decoupling capacitors together in opposite directions,,,, Capacitor model, selection, capacitance calculation and PCB layout and wiring
