RLC Series Circuit Impedance Calculation
Calculate impedance of a series circuit containing resistor, inductor and capacitor at specific frequency
Input Parameters
Calculation Results
Engineering Explanation
At 1kHz frequency, the inductive reactance is approximately 62.8Ω, and capacitive reactance is approximately 159.2Ω. Since capacitive reactance is greater than inductive reactance, the circuit exhibits capacitive characteristics.
PCB Microstrip Characteristic Impedance
Design PCB trace width calculation for 50Ω characteristic impedance
Input Parameters
Calculation Results
Engineering Explanation
For standard FR4 substrate, to achieve 50Ω characteristic impedance, the trace width needs to be approximately 2.7mm. This is the standard impedance value for high-frequency signal transmission.
Capacitor Frequency Response Analysis
Analyze capacitor impedance variation across different frequencies
Input Parameters
Calculation Results
Engineering Explanation
Capacitor impedance is inversely proportional to frequency. When frequency increases by 10 times, impedance decreases by 10 times. This is the fundamental working principle of capacitors in filter circuits.
LC Parallel Resonant Circuit
Calculate resonant frequency and impedance characteristics of LC parallel circuit
Input Parameters
Calculation Results
Engineering Explanation
At resonant frequency, LC parallel circuit exhibits maximum impedance. Higher Q factor results in better selectivity and narrower bandwidth.
