## Description

BenchKit puts four everyday electronics calculations in one focused, offline iPhone app.

RESISTOR COLOR BANDS
Decode 4, 5, and 6-band axial resistors. See the nominal resistance, tolerance range, and temperature coefficient where applicable.

PCB TRACE WIDTH
Estimate minimum internal or external copper trace width from current, copper weight, and allowed temperature rise. Results are shown in millimeters and mils.

VOLTAGE DROP & POWER
Check line voltage drop, delivered voltage, resistive power loss, and retained voltage.

VOLTAGE DIVIDER
Calculate ideal unloaded output voltage, divider current, total dissipation, and Thevenin resistance.

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.
