TDK

The profiles here cover two TDK lines: multilayer ceramic capacitors and power inductors. The ceramic side runs from general-purpose X7R decoupling in 0603 to high-capacitance X5R bulk parts in 1206, the values that sit on input rails and around regulators. The inductor side is the VLS wire-wound power series, low-profile parts chosen for DC-DC conversion where height is the constraint. TDK ordering codes reward careful reading: one string carries series, value, tolerance, case and packing, and TDK also sells under order references that map to a separate catalog part number — the C3216 22 µF profile here documents exactly such a mapping from TDK's own supply-status file, because quoting against the wrong string changes the part being quoted. Match the complete code from your BOM in the RFQ and we will cross-check it against TDK's records before quoting.

Sourcing notes for TDK parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
