2A821M

I can draft a concise, neutral wiki-style article about 2A821M, but I need a bit more context to ensure accuracy. The designation 2A821M can refer to multiple distinct items across different industries (for example electronic semiconductors such as transistors or diodes, integrated circuits, or other components), and there are several products that use similar numbering schemes from different manufacturers. To deliver a precise article, please specify:

- The type of product (e.g., transistor, diode, IC, connector, mechanical part).

- The manufacturer or country of origin, if known.

- Any relevant specifications or usage context (application area, date of introduction, notable variants).

If you’re unsure, I can provide a general overview of how part numbers like 2A821M are typically structured and what information is usually associated with them, then tailor the article once you confirm the exact device.
