Introduction of electrical characteristics simulation
1. Simulation model
【Physical image of package】  

* Define RLC of package before simulation.
This RLC includes gold bonding wire ~ wiring on PCB ~ through hole (T/H) ~ land and up to ball.

~Ladder Model~

R: Resistance [Rs: Resistance]
L: Inductance [Ls: Self Inductance, Lm: Mutual Inductance]
C: Capacitance [Co: Self Capacitance, Cm: Mutual Capacitance]
