## What is ComponentFinder?

Find any electronic component in seconds. ComponentFinder puts specs, pinouts, replacement parts and the manufacturer's datasheet in your pocket — built for hardware engineers, embedded developers, makers and students.

LOOK IT UP FAST
• Search by part number, keyword or parameter — fuzzy matching finds LM358, NE555 or AO3400 even with typos
• Browse 14 categories: resistors, capacitors, inductors, diodes, transistors, MOSFETs, regulators, op amps, logic, memory, MCUs, sensors, connectors and modules
• Works offline with a built-in reference library; datasheet links go straight to the original manufacturer

SCAN A PART LABEL
• Point your camera at a chip and tap its marking — on-device live text scanning, no upload needed
• Or recognize markings from a photo with AI

ASK THE AI ASSISTANT
• Get usage notes, key specs, design warnings and alternatives for a part, with cited sources
• Find a better datasheet when a link is broken or you need a second source

ENGINEERING WORKSPACE
• BOM projects with quantities and notes — export to CSV for your spreadsheet or purchasing team
• Compare up to 4 parts side by side
• Datasheet update alerts notify you when a watched datasheet changes

WORKS THE WAY YOU DO
• Siri and Shortcuts: "Look up a component in ComponentFinder"
• Home Screen and Lock Screen widgets for recently viewed parts
• iPad sidebar layout and keyboard shortcuts on iPad and Mac
• iCloud sync for favorites, history and AI answers
• Available in English, Deutsch, Français, Español, Português, 日本語, 한국어 and Chinese
