SDTR1103CAP
SMD Drop Resistant Transponder
Features
The SDTR1103CAP 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:
∆Ls/Ls (-40ºC 25ºC): -2% max.
∆Ls/Ls (+25ºC +85ºC): +0.5% max.
Typical temperature coef cient ∆Ls/ºC:
+200±50ppm/ºC.
-40ºC to +125ºC for TPMS applications.
-40ºC to +85ºC for Keyless Entry Systems.
Characteristics
- 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.
