Hong Kong, China, July 25, 2017 /ChinaNewswire.com/ – TT Electronics, a global provider of engineered electronics for performance critical applications, launched the HA78D series of coupled inductors for use in DC/DC converter applications. With their high temperature rating and AECQ200 certification, they are ‘automotive ready’ for the latest generation of motor vehicles.

The HA78D series shielded SMD inductors have been designed specially for use in DC/DC converter configurations including flyback, multi-output buck, SEPIC* and Zeta applications.

  • With their high leakage inductance they are ideal for SEPIC applications where the loosely coupled winding improves the SEPIC efficiency by reducing circulating current and provides twice the ripple current reduction compared to separate inductors. nike air max bambini

    In a motor vehicle there are more than 80 electronic applications. Maglia Damian Lillard Each of these uses an ECU, and each ECU requires a DC/DC converter. In 2015, 40% of the total cost of a car was attributable to its electronics.

  • It can be seen that the design of the DC/DC converter for automotive applications is a challenging task when one considers all the requirements that need to be met. Nike Kobe 11 Accordingly, inductors are vital components for achieving the necessary performance and power requirements of automotive DC/DC converters.

    TT Electronics’ HA78D series comprises of four inductors; the HA78D-L128100MLFTR, HA78D-L128220MLFTR, HA78D-L128330MLFTR and HA78D-L128470MLFTR. nike air max 2017 goedkoop When parallel connected, their inductance ratings at 100kHz are 10, 22, 33 and 47 micro Henries consecutively.

    The inductors offer high efficiency and excellent current handling in a rugged housing, and with their low losses ferrite cores they are ideal for high frequency DC/DC converter and VRM/VRD applications. Particularly, their wide -50 to 155#61616;C operating temperature range and AECQ200 certification make them ideal for high stress environments.

    Exhibiting versatility, the RoHS compliant inductors can also be used as two single inductors connected in series or parallel or as a common mode choke as a filter inductor for EMI noise reduction.

  • In the automotive market, the inductors are suitable for applications including lighting, hybrid car, start and stop vehicle, and electrical power steering. Other applications include industrial, telecom, VRM and PoL.

    The HA78D series embraces TT Electronics’ holistic approach to inductor design to create products that are feature rich, safe, highly efficient and reliable. The result is designs and manufacturing solutions for magnetic devices that have a systematic adherence to safety standards and quality as is required by the automotive industry. Nike Free Run Femme The designs allow for smaller and lighter components with more reliable circuits that enhance safety and lower the risk of liability for customers.

    TT Electronics is shown to have high quality, reliable products based on empirical saturation current data, core loss test data, and company wins with major automotive and industrial suppliers.

    * SEPIC (single ended primary inductance converter) is the most popular DC/DC converter topology used in LED drivers in the automotive industry. In this topology the output voltage can be higher or lower than the input voltage. The topology combines characteristics of buck and boost converters and in most cases operates in CCM (continuous conduction mode). As far as the LED drivers in automotive applications are concerned, they don’t need insulation between the input and output sides of the DC/DC converter, so SEPIC topology is ideal for this kind of application.
