The so-called Passive Entry System has revolutionized vehicle opening systems in recent years, becoming a standard within the automotive industry. New key designs increasingly demand lower profiles and more robust electrical and mechanical components (withstanding up to 1,000 impacts from over 1 meter onto a concrete surface). The 3DC14AOI is an antenna composed of 3 orthogonal windings, each of them on the 3 axes of space.
This surface-mount (SMD) component also features side metallization, enabling automatic optical vision (AOI) solder recognition. The pads are gold-plated, ensuring a more secure and higher-quality connection between the component and the PCB circuitry. Furthermore, the contact surface provided by these pads, combined with the lateral menisci formed during the soldering process in the side metallization, increases the mechanical contact between the component and the PCB by more than 25% compared to current products on the market.
The new antenna, designed in a low-profile format (15.7x13.7x3.6mm), offers high robustness since the windings are fully protected by a high-stability vacuum polymer matrix (expansions less than 200ppm and thermal resistance (supports double reflow of 270ºC).
The 3DC14AOI offers high temperature stability performance (-40ºC -> +85ºC) in a compact and fully protected format (protection superior to IP685).
The 3DC14AOI is offered in a standard value of L=7.2 mH with sensitivity greater than 80 mVpp/App/m @125 kHz and maintaining a quality factor Q of 20; recommended for chipsets from Atmel, NXP, TI among others, and can be manufactured with different electromagnetic values on each of the axes according to the needs of the customer.
This transponder complies with AEC-Q-200 (one of the most stringent quality standards for electronic components) for automotive applications. This guarantees the component's performance and reliability in both domestic and industrial settings, and of course, in automotive applications.
