Traco TSR-1 for free! Are you one of them?

No doubt, that switch-mode regulators are a very perspective replacement for low-efficient linear stabilizers. This is also reflected in your interest and in a record participation in the contest published in article - Try the effective replacement for standard 78xx regulators. In total 504 of you, our readers have sent us an answer to a little bit “insidious” question - What inductor is necessary for a proper operation of the TSR-1?

The correct answer is, that TSR-1 is a complete solution comprising an inductor, that´s why it doesn´t need any coil-inductor for a proper operation. In most cases you answered correctly, but many of you also wrote, that an 8,2 uH inductor is necessary. We admit, that the formulation of the question could also be understood in the way, that „What has to be made, in order the TSR-1 to meet EN 55022 class A?“ (when it is necessary to add a Pi filter with 8,2uH coil and two capacitors), that´s why we drawn the winners by lots from all participants.



Thanks for the participation, the winners of Traco TSR-1 regulators are:
