PREMO has in commercial promotion an emitter antenna with 470uH (Q=90) of inductance at 125 kHz (suitable to use also at 134,2kHz, Q=95).
This is an SMD antenna easy to use in an automated pick and place (or even by hand for small series production).
This product, with internal part number X-D830-003, is appropriate for short and medium read range (until 1m, depending on the receiver coil side) and excellent to substitute to air-coil (3-6cm diameter).
Typical capacitor to use with this SMD coil (in series resonance at 125 kHz) is 3.3nF.
NPO/COG capacitor is highly recommended to use with this coil to work properly with pulse signals.
The component is Rohs compliant.
MOQ: 5 units.
