A 01005 capacitor occupies 0.4 mm × 0.2 mm of board real estate, roughly the cross-section of a human hair. Fifteen years ago that package was exotic; today Yageo, Murata, Samsung, and Walsin ship 01005 MLCCs and chip resistors by the billion for wearables, hearables, and implantable medical devices. The question for PCB designers is whether the a…
Buying ICs from Shenzhen, PCBs from Malaysia, or passives from a UK distributor post-Brexit means customs will eventually ask for paperwork you did not prepare. Here is what you need: VAT treatment by import scenario, TARIC classification for common electronic parts, the non-negotiable documents, and how to avoid shipments held for weeks while you…
Most engineers send a part number list and wait. Procurement teams that get it right send a structured RFQ and close the gap between BOM cost estimate and landed price before the design review starts. The difference is what information you include, how you format it, and who you send it to.
You find the exact capacitor your design needs. Voltage rating and tolerance are perfect, the price is reasonable. Then the MOQ is 4,000 pieces when your prototype needs 50. Minimum order quantities are the most common friction point in electronic component sourcing. They are not arbitrary: packaging economics, factory minimums, and distributor co…
