Roadmap / Hardware
Practical Components
Even a single resistor on a schematic needs a rating, tolerance and package before it becomes a board.
Goal Pick real parts from their datasheets.
- 01Choosing resistors3D lab
Power rating, tolerance, temperature coefficient, and packages such as 0402 and 0603.
- 02Types of capacitors
MLCC, electrolytic, tantalum, and the DC-bias trap that shrinks MLCC capacitance.
- 03Inductors and ferrite beads
Saturation current, DCR, and beads that absorb noise.
- 04Crystals and oscillators
The source of the MCU clock. Load capacitors and placement.
- 05Connectors and terminals
Current rating, pitch, locking: the most common point of failure in the field.
- 06Fuses and protection parts
How to choose polyfuses, TVS diodes and varistors.
- 07Pull-ups, pull-downs, decoupling3D lab
Resistors that hold a floating pin, and capacitors that steady the supply next to a chip.
- 08Reading a datasheet
Absolute maximum ratings, recommended conditions, electrical tables, timing diagrams.
