ElectroCalc Pro vs BenchKit

ElectroCalc Pro is the essential utility for electronics engineers and hobbyists. Simplify your daily circuit calculations with this powerful tool. [Key Features] 1. Basic Electronics - LED Resistor Calculator - Voltage Divider Calculator (Vin, R1, R2, Vout) - LM317 Voltage Regulator Calculator 2. Power & Cables - Ohm's Law Calculator (Voltage, Current, Resistance, Power) - AWG (American Wire Gauge) Table & Conversion 3. Battery Tools - Battery Runtime Calculator - Battery Configuration Calculator (Series / Parallel) 4. PCB Tools - PCB Trace Width & Resistance Calculations

BenchKit puts four everyday electronics calculations in one focused, offline iPhone app. RESISTOR CODES Decode 3, 4, 5, and 6-band axial resistors by tapping the bands on a drawn resistor, or SMD codes (3-digit, 4-digit, EIA-96, R notation). See the tolerance range, IEC marking code, and standard E-series match, with a warning when a reading is probably reversed. PCB TRACE WIDTH Estimate minimum internal or external copper trace width from current, copper weight, and allowed temperature rise, in millimeters and mils, or the current a given width can carry. Results outside the IPC-2221 chart range are flagged as extrapolations. VOLTAGE DROP Voltage drop, voltage at the load, power lost in the wiring, and the share of supply that reaches the load. Enter the round-trip resistance, or wire gauge (AWG or mm²), length, and conductor temperature. VOLTAGE DIVIDER Ideal unloaded output voltage, divider current, per-resistor dissipation, output resistance, and what an optional load does to the output. Or enter a target voltage and get the closest E24/E96 resistor pairs with their worst-case output. Type values the way engineers write them: 4k7, 2R2, 100m, 3V3; the keyboard has keys for the letters. No account. No ads. No analytics. No network connection. English, Simplified Chinese, and Japanese. BenchKit is a quick estimation tool. Always verify production designs against component datasheets, applicable standards, simulation, and physical validation.
