Eighth-brick convertors power up to 100W
Murata Power Solutions has a new series of cost-effective eighth-brick DC/DC convertors.
DC/DC databook includes quick selection guides
Guides help design engineers quickly identify the most suitable DC/DC convertor for their given application.
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.
CD1243 inductors have an operating temperature range of -40 to +85C and are supplied in tape and reel packaging. Request a free brochure from Murata Power Solutions ...
