RFID Transponder Coils – 4308TC
Coilcraft’s new family of antenna coils are rugged, high
performance devices intended for RFID applications at
125 kHz.
These low profile parts have an extended length that
allowslongerreadrangesandhighersensitivity.Thecoil
is constructed of ferrite laminated onto a ceramic base,
whichmakesitmoreruggedandimpactresistantthanall-
ferrite constructions. An encapsulated top ensures reli-
able pick and place operations.
In addition to the standard models shown, Coilcraft can
design transponder coils designed to operate at other
frequencies.
Coilcraft Designer’s Kit C145 contains four samples of
each value shown. To order, contact Coilcraft or visit

1. Inductance and Q measured using Agilent/HP 4192A impedance analyzer. For recommended test procedures, contact Coilcraft.
2. Matching capacitor value required for parallel resonant circuit operating at 125 kHz.
3. DCRmeasuredonmicro-ohmmeter.
4. SRF measured using Agilent/HP 8753D network analyzer.
5. Read distance measured using the KEELOQ® Transponder Evaluation Kit part number DM303005 from Microchip. Distance was recorded as the voltage
across the resonant circuit dropped below 10 mV.
6. Operating temperature range −40°C to +85°C.
7. Electrical specifications at 25°C.
