4308RV-115X Datasheet | Coilcraft

Document 324-1 RFID Transponder Coils - 4308RV Coilcraft’s 4308RV antenna coils are high performance devices intended for RFID applications at 125 k Hz. These low profile parts have an extended length that allows longer read ranges. An encapsulated top ensures reliable pick and place operations. Core construction and encapsulation are rated for 125°C, which makes these transponders ideal for higher temperature applications. For harsh environments, please consider the 4312RV or 5315TC, which were developed for tire pressure monitoring systems. The 4308RV transponders coils are available in 5% and 2% tolerances. In addition to the standard models shown, Coilcraft can design coils to operate at other frequencies. Coilcraft Designer’s Kit C383 contains four samples of all 5% inductance tolerance parts.
