TL5025u UHF RFID label within NXP U9 RFID chip The FL5025u is a compact, high-performance UHF RFID label designed for demanding item-level tracking applications across aviation, apparel, and retail industries. Measuring just 50 mm × 25 mm, this label delivers an excellent balance of read range and form factor, making it ideal for space-constrained applications where consistent performance is critical.   Engineered with the NXP UCODE 9 chip, the FL5025u leverages industry-leading RAIN RFID technology to deliver exceptional read sensitivity of -24 dBm and write sensitivity of -22 dBm . This high sensitivity enables reliable inventory counts and faster encoding speeds (32 bits in just 0.96 ms) compared to previous generations . The chip features Self-Adjust technology for automated tag performance optimization in challenging environments and Memory Safeguard to protect against data corruption during writing .   The label operates across the global UHF frequency band (860–960 MHz), ensuring seamless deployment in multiple regions including North America (FCC), Europe (ETSI), and Asia（CMII）. The aluminum-etched antenna on PET substrate delivers typical read ranges of up to 4–6 meters (depending on reader configuration and environment) .     Built for durability, the UCODE 9 chip supports 100,000 write cycles and 20 years data retention, with an extended operating temperature range of -40°C to +85°C suitable for demanding logistics environments . The 96-bit EPC memory supports pre-serialization, while the factory-locked 96-bit TID includes a 48-bit unique serial number for reliable item identification .
