계산 시작

RLC 계산 예제

각 예제에는 상세한 매개변수 설정, 계산 결과 및 엔지니어링 설명이 포함됩니다

RLC 회로초급

RLC 직렬 회로 임피던스 계산

특정 주파수에서 저항, 인덕터 및 커패시터를 포함하는 직렬 회로의 임피던스 계산

입력 매개변수

저항 (R):100 Ω
인덕턴스 (L):10 mH
커패시턴스 (C):1 µF
주파수 (f):1 kHz

계산 결과

임피던스 크기:∼108.7 Ω
위상각:∼25.8°
품질 계수:∼0.63

엔지니어링 설명

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 설계중급

PCB 마이크로스트립 특성 임피던스

Design PCB trace width calculation for 50Ω characteristic impedance

입력 매개변수

Substrate Thickness:1.6 mm
Dielectric Constant:4.5
Trace Thickness:35 µm
Target Impedance:50 Ω

계산 결과

Trace Width:∼2.7 mm
Effective Dielectric:∼3.1
Actual Impedance:∼50.2 Ω

엔지니어링 설명

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.

Frequency AnalysisIntermediate

Capacitor Frequency Response Analysis

Analyze capacitor impedance variation across different frequencies

입력 매개변수

Capacitance:100 nF
Frequency Range:1 Hz - 1 MHz
ESR:Ignored
ESL:Ignored

계산 결과

Impedance at 1 kHz:∼1.59 kΩ
Impedance at 10 kHz:∼159 Ω
Impedance at 100 kHz:∼15.9 Ω

엔지니어링 설명

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.

Resonant CircuitsAdvanced

LC Parallel Resonant Circuit

Calculate resonant frequency and impedance characteristics of LC parallel circuit

입력 매개변수

Inductance:1 mH
Capacitance:10 nF
Inductor Q Factor:100
Analysis Frequency:Around resonance

계산 결과

Resonant Frequency:∼50.3 kHz
Resonant Impedance:∼31.4 kΩ
Bandwidth:∼503 Hz

엔지니어링 설명

At resonant frequency, LC parallel circuit exhibits maximum impedance. Higher Q factor results in better selectivity and narrower bandwidth.
