Decoupling Capacitor

OverviewPinoutRelated groups
Decoupling Capacitor — decoupling-capacitor

Generic two-terminal capacitor used across power rails to reduce supply noise. Exact capacitance and voltage rating should be selected per circuit.

Pinout

  • Terminal 1

    Connect to one side of the rail or signal being decoupled.

  • Terminal 2

    Connect to the return side, usually ground. Observe polarity for polarised capacitors.

Level shifters

Pick level shifters by bus behavior: I2C/open-drain, auto-direction push-pull, direction-controlled buffers, or 3 V to 5 V logic. They are not universal adapters.

Displays

Character LCDs, SPI TFTs, e-paper modules and larger capacitive-touch TFT panels solve different display jobs. Treat display class, interface, controller, resolution, touch, refresh behaviour, storage, voltage and mounting as separate swap checks.
