RFID Transponder Coils Coilcraft RFID Transponder Coils offer up to 5% tolerance and are designed for RFID applications at 125kHz. The 4308RV series features a low profile design and an extended length that allows longer read ranges. The 4312RV and 5315TC components are designed to withstand harsh mechanical shock, making them ideal for tire pressure monitoring systems. 4513TC coils offer better sensitivity, greater read distance, and higher SRF than other coils its size. ZXC Z-axis coils are 10mm x 2mm and can be used with any other RFID coils for complete three-dimensional solutions. The 4513TC, 4312RV, and 5315TC series are AEC-Q200 compliant.
