Q.ESR characteristics (4): Does frequency affect ESR?
Capacitors > Ceramic Capacitors > Multilayer Ceramic Chip Capacitors
There are a number of factors that are important to consider for circuit design.
Electrically, ESR is affected by the frequency of the circuit. This is evident in the formula for ESR shown in Formula 1.
ESR = DFXc = DF/2πfC （Formula 1）
