Bruce Rose, Principal Applications Engineer, CUI Inc A buzzer can provide a cost-effective yet intuitive aspect to the user interface of a wide variety of products, such as a home appliance, security panel, door-entry system or computer peripheral. Usually, the choice is between either a magnetic or piezoelectric type. It should be an easy decision, […]
Power supply designers take a hard look at soft magnetics
The promise of high efficiency and small size brought by super-fast switching power supplies could be delayed by a lack of magnetic materials that are up to the task. Leland Teschler | Executive Editor Eyeball the schedule for APEC, considered the premier technical conference for power electronics, and you’ll notice a number of sessions devoted […]
Double choke optimized for SMT assembly
With its WE-TDC HV, Würth Elektronik eiSos presents a further double choke optimized for SMT assembly. The magnetically shielded 1:1 transformers with an isolation voltage of 2,000 V stands out from similar components through lower losses and a low level of stray inductance. The WE-TDC HV product family encompasses nine different models – five in […]
Hone your design skills in a magnetics workshop
The 2019 version of the Magnetic Bootcamp will happen on Thursday, January 24, 2019, in Orlando, Fla. In 2019, the Bootcamp will be shortened to five hours.
