Parts

Use these pages to compare families and parameters before you open a distributor search. Tables list commodity parts only — verify every row against the current datasheet.

• Buck (step-down) converters

  Switching regulators for efficient step-down rails.

• Ceramic capacitors (MLCC)

  Dielectrics, voltage derating, and bypass placement.

• Electrolytic capacitors

  Bulk input and output capacitors — ripple, ESR, and lifetime.

• General-purpose diodes

  Rectifiers and switching diodes for protection and ORing.

• Indicator and lighting LEDs

  Forward voltage, current, and package styles for common LEDs.

• Li-ion battery charger ICs

  Linear and switching chargers — charge current and cell count.

• Linear voltage regulators

  LDO and fixed linear regulators — dropout, heat, and when a switcher wins.

• N-channel MOSFETs

  Low-side switches — Vgs, Rds(on), and package.

• SMD resistors

  Thick-film chip resistors — size, tolerance, and power.

• Timers

  Classic timer ICs — NE555 family astable and monostable timing.

• USB UART bridges

  USB to serial adapters on a PCB — drivers and logic levels.

• Voltage references

  Programmable shunt references and precision voltage references — TL431 family and equivalents.
