Inductor helps shrink Trafficmaster telemetry unit
Trafficmaster has worked in partnership with C and D Technologies to develop a custom inductor solution for use in its Smartnav system.
Trafficmaster has worked in partnership with C and D Technologies to develop a custom inductor solution for use in its Smartnav system. The resultant component, the CD1243, is a high performance, surface mount, low-profile bobbin format inductor with dual winding. Overcoming a challenging design brief, C and D Technologies engineers have successfully realised a design acceptable to Trafficmaster's exacting electrical, physical and thermal criteria.
With Smartnav, the expensive hardware and mapping database associated with conventional line fitted in-car systems is housed off-board in a central server computer.
The only hardware in the vehicle is a GPS satellite-based positioning device and a small telematics control unit (TCU).
Occupying only 25% of the PCB area of the previous solution, and with a height of just 8mm, the CD1243 helped Smartnav's designers keep the TCU's overall size to a minimum.
As the unit is designed for the automotive aftermarket, small dimensions are essential in order for the unit to be fitted discreetly in the vehicle cabin.
With the proliferation of electrical and electronic equipment now present in passenger vehicles, the operating environment is electrically very noisy; To combat the problems that this can cause and ensure reliable operation, the CD1243 features an integral EMI shield to protect the device against spurious noise.
