Smart-card Reader Protection

Problem: Short-circuit overload

Defective cards or foreign objects placed into the reader can cause a short-circuit and permanently damage the reader.

 

Solution: PolySwitch devices.

PolySwitch devices limit the flow of dangerously high currents during fault conditions and reset back to normal operating mode once the fault condition is removed.

Applicable Product Series: microSMD, nanoSMD
Download SMD Datasheet - (pdf 439KB)
Agency Recognition: UL E74889, TÜV R9872049, R9872048, R2172061, CSA 078165_C_000.

 

Problem: Transient Surge Voltages and Electrostatic Discharge (ESD)

Transient surge voltages caused by equipment switching operations and also electrostatic discharge (ESD) can damage the equipment.

 

Solution: PESD devices.

PESD, which is a low capacitance (typically 0.25pF) ESD protection device, is capable of withstanding numerous ESD transients, and is a RoHS & IEC61000-4-2 compliant device having low leakage current and low clamping voltage.
