UC1103C SMD Drop Resistant Transponder Coil 
 
UC1103C  SMD Series of Surface Mount ferrite wound inductor is the best solution when high electrical and mechanical performance is needed. Its length and cross sectional area are optimized to achieve the maximum sensitivity in the coil axis. The construction of the coil offer high mechanical performance due to the plastic base and ferrite laminate.
High stability in temperature, ranges:
ΔLs/Ls (-40oC ? 25oC): -2% max.
ΔLs/Ls (+25oC ? +85oC): +0.5% max.
Typical temperature coefficient ΔLs/oC: +200±50ppm/oC.
-40oC to +125oC for TPMS applications.
-40oC to +85oC for Keyless Entry Systems.
 
High sensitivity. 75 mVpp/App/m for 7.2 mH (@125 kHz). 135 mVpp/App/m for 16.2 mH (@125 kHz).
Mechanical performance. Drop test: more than 500 times x 1 meter.
CAP protection, 5 sides protected , high reliability with Pick&Place machines warranted.
Taped & Reel: 3000pcs / reel.
Inductance values from 340μH to 16.2mH for 125KHz operations (contact PREMO RFID for inductance range for other working frequencies such as 20KHz and 40KHz).

Applications:
Inmobilizers.
Tire pressure monitoring systems.
Keyless entry Systems.
Industrial applications.
Access control.
