IDTS-0803 Ultra-Miniature UHF On-Metal RFID PCB Tag 8 x 3 x 4.3 mm for Small Tools, Instruments & PCBs

The IDTS-0803 is an ultra-miniature UHF on-metal (anti-metal) RFID tag from IDentium, built on a rigid black PCB body measuring just 8 x 3 x 4.3 mm. It is sized for the assets that normally defeat RFID altogether — small metal parts, instruments and sub-assemblies where there is simply no room for a conventional on-metal tag. Despite the miniature rectangular bar format, it is an anti-metal design and delivers a read range of approx. 0.5 m on metal, with an operating temperature rating of -20 C to +150 C.

Applications

• Serialising bare PCBs, electronic modules and sub-assemblies through production and rework
• Tracking surgical, dental and laboratory instruments where the tag must sit on a slim metal shank
• Tool crib issue-and-return for small hand tools, drill chucks, inserts and cutter holders
• Identifying precision jigs, fixtures, gauges and calibration items on the shop floor
• IT asset audits covering small metal items — connectors, rack accessories, adapters and modules
• Marking small valves, fittings, couplings and probes in pharma, utilities and process plants
• MRO and railway workshop spares that are too small to carry a label or a full-size on-metal tag

Why Choose This Tag

• Genuinely miniature footprint. At 8 x 3 x 4.3 mm in a rectangular bar shape, it fits assets that larger on-metal tags cannot be placed on at all.
• Built for metal. An anti-metal design that reads at approx. 0.5 m on metal — the read distance is quoted on a metal surface, not in free air.
• Impinj Monza R6-P chip on ISO18000-6C. Works with standard ISO18000-6C readers and handheld terminals, with 128 bit EPC, 96 bit TID and 32 bit User memory for serialisation and factory-programmed unique identity.
• Wide -20 C to +150 C operating temperature rating. Suited to deployments that move between cold storage and hot process areas.
• Rugged PCB construction. A rigid black PCB body with two silver plated ring pads on the top face, supplied and supported in India by India RFID Store under the IDentium / IDTS brand.

Read range figures are typical and will vary with the reader and antenna used, transmit power, the mounting surface and the surrounding environment. We recommend a site trial with your own reader before large-volume rollout.

Frequently asked questions

How small is the IDTS-0803 and what fits it?

The rigid black PCB body measures just 8 x 3 x 4.3 mm, which sizes it for assets that normally defeat RFID altogether: small metal parts, hand instruments, sub-assemblies and boards where there is no room for a conventional on-metal tag. It keeps the anti-metal design despite the miniature bar format.

What read range does it achieve on metal?

It delivers approximately 0.5 m on metal, which is short by design because of the tiny antenna area. That suits close-range work such as tool issue and return, calibration checks and bench scanning rather than portal or long-range inventory sweeps, so plan the reader position around a near-contact read.

Which chip and temperature rating does it use?

The tag carries an Impinj Monza R6-P chip and is rated for -20 C to +150 C operation. That temperature range lets it stay fitted through hot process steps and unconditioned storage, while the Monza R6-P keeps it compatible with the standard passive UHF readers used across Indian plants and workshops.

Can Identium encode these before shipping?

Yes. Identium is a BIS and WPC certified Indian manufacturer and can encode EPC or user data to your numbering scheme before dispatch, which saves handling on parts this small. Pricing depends on quantity, so check the listed price or send your volume for a bulk quote and samples.
