Common Electronic Design Calculations
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 Try our LC Filter Calculator
- Low-pass and high-pass filters
- Band-pass and band-stop filters
- Multiple-stage filters
- Custom filter responses
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.
- Calculate microstrip and stripline impedances
- Design differential pairs
- Account for manufacturing tolerances
- Generate detailed impedance reports
How to calculate power supply requirements?
Power supply calculations involve determining total current draw, voltage regulation requirements, and efficiency factors.
- 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.
How to calculate heat sink size?
Heat sink sizing depends on power dissipation (Pd), maximum junction temperature (Tj), ambient temperature (Ta), and thermal resistances.
- Heat Sink Calculator - Size your heat sink
- Junction Temperature Calculator - Verify thermal limits
- Thermal Resistance Calculator - Analyze thermal paths
These Calculators help ensure your components operate within safe temperature limits while optimizing cooling solution size.
