Electronics Toolbox is your go-to app for quick, reliable electronics calculations.
What sets it apart? Most of the included calculators can instantly generate LTspice test circuits and components—so you can validate results right away and drop subcircuits directly into your own designs.

Main features:

* Ohm’s Law, dB, V Peak / V RMS
* Resistors (parallel, color code, best combination)
* Voltage Dividers (with LTspice test circuits)
* LED Resistor, Capacitors in Series, Capacitance Converter
* RC & RL Time Constants (with LTspice test circuits)
* Op-Amp circuits (inverting, non-inverting, difference, Howland) (with LTspice test circuits)
* Filters: RC / RL / RLC Low-Pass, High-Pass, Band-Pass, Band-Stop (with LTspice test circuits)
* NE555, LM317, Wheatstone Bridge (with LTspice test circuits)
* Common Emitter BJT amplifier (with LTspice test circuit)
* Junction temperature and heatsink calculations

Whether you’re a student, hobbyist, or professional, Electronics Toolbox makes design work faster, easier, and more accurate.
