With extended coil length that allows longer read ranges and higher Q, the 4308TC series transponder coils are designed for radio frequency identification (RFID) applications at 125 kHz. Sporting a rugged, ferrite-laminated-to -ceramic base design, the coils measure 11.8 mm x 3.6 mm x 3.1 mm. With 11 models in the series, inductance values range from 0.4 mH to 8.1 mH and the company can provide different values for frequencies other than 125 kHz. Price is $0.45 each/10,000.
