10 nF at 16V in 0402 — what the spec means for the BOM
Taiyo Yuden EMK105B7103KVHF is a 10000 pF (10 nF) multilayer ceramic capacitor rated for 16V in the 0402 (1005 metric) surface-mount footprint — 1.00 mm by 0.50 mm with a maximum thickness of 0.55 mm. The X7R temperature coefficient means capacitance shifts within ±15% across the full operating window — acceptable for SMPS filtering and decoupling paths where absolute precision is secondary to bulk storage and switching noise absorption.
AEC-Q200 grade — what it adds to the qualification sheet
The AEC-Q200 rating is the qualification floor for automotive passive components: it tests the part against temperature cycling, moisture resistance, board-flex stress, and vibration — the failure modes that kill MLCCs in engine-compartment and chassis locations. If you are writing a DFM for an automotive control unit and the BOM already carries multiple X7R 0402s without AEC-Q200, swapping them for an AEC-Q200 grade like the EMK105B7103KVHF can close a qualification gap without a board spin — the footprint and voltage rating are identical.
Thin profile and packaging — feeder-ready check
The 0.55 mm maximum thickness sits at the thin end of the 0402 range — confirm the reel orientation and pick-feeder shoe clearance before committing to high-speed SMT. CT is useful for low-volume NPI runs and prototype strip sheets.
