YFF18AC Overview

What changes between part numbers, and what to check before you lock the BOM — Passive Components.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
4 distinct suffix patternsExamples: 0J105MT0Y0E, 1C104MT0Y0N, 1E223MT0Y0N, 1H103MT0Y0N. Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Passive Components — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

How to Choose the Right YFF18AC Passive Components

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For YFF18AC, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "YFF18AC" — include the full suffix (e.g. 0J105MT0Y0E, 1C104MT0Y0N, 1E223MT0Y0N). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the YFF18AC product family.

Is YFF18AC a single part I can order, or a family prefix?

YFF18AC is a base / family code from TDK. You order a full MPN such as YFF18AC0J105MT0Y0E, YFF18AC1C104MT0Y0N, YFF18AC1E223MT0Y0N. The variant table lists 4 orderable lines with different suffixes.

What do the suffix letters on YFF18AC part numbers mean?

Listed suffix fragments include: 0J105MT0Y0E, 1C104MT0Y0N, 1E223MT0Y0N, 1H103MT0Y0N. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the TDK datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of YFF18AC variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on YFF18AC?

Full manufacturer MPN (not just YFF18AC), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
