Modern rail infrastructure requires a wide range of DC-DC converters to power a variety of new safety systems and passenger services, as well as creating a need for performance improvements in existing systems for both freight and commuter markets. Power density, efficiency and ease of use are critical considerations when designing isolated, regulated DC-DC converter systems for modern rail applications. The new DCM2322 ChiP family is a lower-power and smaller package variant of the DCM3623 family and provides power system engineers a smaller footprint option with input voltage ranges that meet multiple EN50155 standards.

Packaged in a 22 x 23 x 7mm ChiP, the new series offers engineers wide input voltage ranges of 43 – 154V and two more narrow input voltage ranges of 14 – 72V and 9 – 50V, with power levels ranging from 35 to 120W and efficiencies up to 90.5%.

The extensive family of isolated DCMs utilize the Vicor high-frequency zero-voltage switching topology to achieve industry-leading thermal and electrical performance, with power densities five times greater than competing DC-DC converters.

TE Connectivity Announced Ultra Small Spring Fingers

TE Connectivity (TE)’snew ultra small spring fingers have one of the smallest footprints in the market to save valuable PCB space, allowing for use in a broad range of applications with space constraints across various industries.TE’s ultra small spring fingerscan save valuable PCB space with one of the smallest footprints in the market. Closed-loop contact design ensures reliable connection to the PCB, better normal force and higher current capacity (1.5A). Robust side wall minimizes over- compression. Special anti-lifting design can improve assembly e ciency by locking the tip of the contact within the sidewall of the spring  nger, which helps prevent the contact from getting caught on an operator’s glove during assembly. Pick-and-place area supports auto-assembly processes. It also offered in different heights and styles.As an authorized distributor for TE Connectivity, Heilind Asia provides TE’s products and also value added services. Heilind Asia supports both original equipment …
