FAQ
How do passive and active components differ in circuit design?
Passive components like resistors, capacitors, and inductors manage energy flow without external power. Active components such as transistors, ICs, and voltage regulators require power to amplify or control signals. We prioritize sourcing both types to ensure optimal functionality for your PCB designs.
Why is visual identification critical when selecting components?
Photos help verify markings, package sizes, and polarity indicators—especially for diodes, LEDs, and surface-mount devices. Misidentifying parts like light-dependent resistors or Zener diodes can lead to circuit failures. We provide detailed datasheets and imagery to minimize sourcing errors.
What factors determine component selection for PCB assembly?
Consider voltage ratings, current flow requirements, temperature tolerance, and footprint compatibility. For example, motor drivers need robust power supplies, while sensors like LDRs require precise resistance matching. We test components like relays and connectors to meet your project’s durability standards.
How do resistors and capacitors function differently in circuits?
Resistors limit current flow and divide voltages, whereas capacitors store energy, filter noise, or stabilize power supplies. Thin-film resistors suit high-frequency applications, while electrolytic capacitors handle bulk energy storage. We stock multiple types, including variable resistors and ceramic capacitors.
