A disturbing a radio I can not judge because I do not have FM radio.
The transformer is small and easy to get to the terminals.
As with any LED transformer you should of course be on the correct connection of the poles and you should the specified wattage (15 watts here) do not make full use of (I think to have heard once that 20% reserve capacity should remain available).
Those who observe this, will be pleased with this transformer.
