Small UHF RFID Paper Label 33x13-U9 (33 × 13 mm)

Small 33 × 13 mm UHF RFID label for compact items

The 33x13-U9 is a small paper UHF RFID label for items that cannot take a standard-size label: component bins, small cartons, files, accessory packs and boxed automotive spares. It is built on the NXP UCODE 9 chip with up to 96 bits of EPC memory, enough for a GS1 SGTIN-96 or your own serial number.

The face is white paper, supplied blank, so you can print a part number, barcode or logo next to the encoded EPC. That lets staff still read the item by eye or with a barcode scanner while RFID handles bulk counts.

Read range and placement

Rated read range is up to 5 m, depending on the reader. A short antenna reads best when the label faces the reader antenna, so apply it flat on the side of the item that will face the reader. As a paper label it suits dry indoor storage within −20 °C to 50 °C; moisture, liquids and direct contact with metal all reduce performance.

When to choose a larger label

Pick the 33 × 13 mm size only where space is tight. If the item has room, a larger label such as the 50 × 30 mm UHF label has a bigger antenna and is more forgiving of placement. To compare UCODE 9 with other common chips, see the Impinj vs NXP chip guide.
