Electrician RF Power Toolkit のアプリ分析 5月21日

Electrician RF Power Toolkit gives electricians, service techs, RF hobbyists, electronics builders, and bench technicians a practical set of calculators for everyday electrical and radio work. It is made for the jobs where you need a number now: checking a circuit, sizing a resistor, comparing power levels, working through a coax problem, checking VSWR, estimating reactance, or saving a field note before you move on. Use it for: - Ohm's law calculations - Voltage, current, resistance, and power checks - Watts, amps, and voltage relationships - Resistor power and voltage drop - dB, dBm, watts, and volts RMS conversion - Return loss, VSWR, mismatch loss, and reflection coefficient - Coax cable impedance, capacitance, and inductance - Capacitor and inductor reactance - RLC impedance estimates - Frequency, wavelength, and cable delay - Skin depth by material and frequency - Pi and T attenuator design - Transformer turns ratio checks - Parallel resistance and tolerance ranges - Binary and hexadecimal conversion - Percentage, ppm, mean, median, and standard deviation - Geometry and unit conversions - Saved records for notes, measurements, job sites, cable runs, and components Popular calculator tools include: - Ohm's Law Solver - Power in Circuit - dB Converter - Return Loss / VSWR - Reactance Calculator - Impedance Calculator - Coax Cable Calculator - Attenuator Designer - Skin Depth - Frequency / Wavelength / Delay Electrical and power tools: - Solve voltage from current and resistance - Solve current from voltage and resistance - Solve resistance from voltage and current - Calculate watts from volts and amps - Calculate current from watts and voltage - Calculate voltage from watts and current - Estimate resistor power using V squared over R - Estimate resistor power using I squared R - Check high dissipation situations before choosing parts RF and signal tools: - Convert dBm to volts RMS - Convert volts RMS to dBm - Convert watts to dBm - Work with 50 ohm and 75 ohm systems - Calculate return loss from impedance - Calculate VSWR from reflection coefficient - Estimate mismatch loss - Compare voltage ratio and power ratio in dB - Work through antenna, feedline, and station checks Coax and transmission line tools: - Estimate coax characteristic impedance - Use inner diameter, outer diameter, and dielectric constant - Estimate capacitance per meter - Estimate inductance per meter - Convert frequency to wavelength - Convert wavelength to frequency - Estimate cable delay from length and velocity factor - Estimate stub filter frequency Component and bench tools: - Capacitive reactance - Inductive reactance - RC series impedance - RC parallel impedance - RLC magnitude and phase - Parallel resistor total - Tolerance minimum and maximum - Transformer voltage ratio - Transformer impedance ratio - Air core coil estimate with Wheeler formula Records are included for real job follow-up: - Add tags for fast searching - Flag important records - Duplicate records for repeat jobs - Share saved record summaries - Import and export records as JSON backups Why it works well in daily use: - Clean calculator sections - Searchable calculator list - Fast numeric entry - Unit pickers where they matter - Clear output cards - Reset, randomize, and share actions - iPhone and iPad friendly layout - No spreadsheet setup - No hunting through unrelated consumer tools - Field notes and calculations live in the same app Good fit for: - Electricians - Electrical contractors - Low voltage technicians - RF technicians - Radio amateurs - Electronics repair techs - Bench technicians - Audio and signal techs - Maintenance teams - Students learning electrical formulas - Makers working with circuits, coax, and components Electrician RF Power Toolkit keeps the work simple: enter the known values, read the result, save or share what matters, and get back to the job.
