Characteristics
Keyless Go Automotive SMD Antenna for transmitting
This emitter antenna is specifically designed for applications in which it is necessary to get a big read range with a minimum size on PCB in low frequency base stations (125KHz and 134.2KHz).
It is a perfect solution to be used in vehicles passive entry applications (PE, passive entry) or TPMS (Tire Pressure Monitoring system).
It has 75mm x 15mm x 6.3mm for SMD assembly. The module antenna is formed only by ferrite core wound inside of a plastic housing and it filled with resin of polyurethane. Also this emitter antenna has the alternative or option to incorporate 2 types pins: through hole or SMD.
- The antenna can be design with different sizes (small, medium, big) , ranges diameter wire (Ø=0.100, 0.180, 0,300 and 0.500mm) and 2 types pins: through hole or SMD.
- High reading distance depending of the size ferrite core.
- Designed for a range of working frequency LF (20kHz, 125kHz and 134,2kHz).
- Antenna current. Max. 4 App, Duty 30%
- High stability in temperature (- 40ºC to +85ºC).
- Good cost/performance ratio.
The specification chart is a reference guide for the most common required values at working frequencies of 125 kHz, 20 kHz and 134.2 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales deparment for any inquiry.
