T491C Overview

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

T491C is a Yageo order-code family — not a single orderable MPN. This page lists 41 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.

1uF 50V Tantalum Capacitor, 10% Tol, SMD Other listed variants describe: 1uF 50V Tantalum Capacitor, SMD, 20% Tol; 10uF 25V Tantalum Capacitor, 10% Tol, SMD, 6032.

Suffix examples in this family: 105K050AT, 105M050AT, 106K025AT7280, 106K035AT, 106M010AT, 106M025AT, 106M025AT7280, 107K010AT. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.

Example MPNs: T491C105K050AT, T491C105M050AT, T491C106K025AT7280, T491C106K035AT, T491C106M010AT, T491C106M025AT.

Ordering Code Differences

How suffixes on T491C map to package, grade, and reel options.

T491C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.

Suffixes seen here: 105K050AT, 105M050AT, 106K025AT7280, 106K035AT, 106M010AT, 106M025AT, 106M025AT7280, 107K010AT, 107K016AT, 107M006AT (+31 more).

Full MPN examples: T491C105K050AT, T491C105M050AT, T491C106K025AT7280, T491C106K035AT, T491C106M010AT.

Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.

How to Choose the Right T491C 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 T491C, 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 "T491C" — include the full suffix (e.g. 105K050AT, 105M050AT, 106K025AT7280). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the T491C product family.

Is T491C a single part I can order, or a family prefix?

T491C is a base / family code from Yageo. You order a full MPN such as T491C105K050AT, T491C105M050AT, T491C106K025AT7280. The variant table lists 41 orderable lines with different suffixes.

What do the suffix letters on T491C part numbers mean?

Listed suffix fragments include: 105K050AT, 105M050AT, 106K025AT7280, 106K035AT, 106M010AT, 106M025AT. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Yageo datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of T491C 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 T491C?

Full manufacturer MPN (not just T491C), 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.
