Common Electronic Design Calculations
Q: How to calculate component values for filter design?
Filter component values depend on the desired cutoff frequency (fc) and filter type. For low-pass RC filters, use C = 1/(2π×fc×R). For LC filters, the resonant frequency is fr = 1/(2π√LC). Try our RC Filter Calculator and LC Filter Calculator to quickly determine optimal component values for your specific requirements.
- Low-pass and high-pass filters
- Band-pass and band-stop filters
- Multiple-stage filters
- Custom filter responses
Q: How to calculate PCB trace impedance?
PCB trace impedance depends on trace geometry, board material (Er), and stackup. For microstrip lines, factors include trace width, height above ground plane, and copper thickness. Use our comprehensive PCB Impedance Calculator to:
- Calculate microstrip and stripline impedances
- Design differential pairs
- Account for manufacturing tolerances
- Generate detailed impedance reports
Q: How to calculate power supply requirements?
Power supply calculations involve determining total current draw, voltage regulation requirements, and efficiency factors. Our Power Analysis Calculator helps you:
- Calculate total power requirements
- Determine voltage regulation needs
- Analyze efficiency and losses
- Size power components properly
For AC applications, check our Power Factor Calculator to optimize power delivery.
Q: How to calculate heat sink size?
