Our surface mount transponder coils (wire wound) series cover a wide range of electrical performances. Its length and cross section area are optimized for best
sensitivity in the coil axis. Customized inductance values are available on request.
Used for wireless data transmission in low frequency RFID products, such as immobilizers, TPMS, keyless entry. Other industrial applications
include access control and tracking devices.
