    Sorry I can't remember (or find) the colleague  who recommended these.

    I have tried one in my Pioneer sub (admittedly on 458 Mhz where noise and glitches are generally no problem) on several occasions and it works fine. It may have changed my generally negative view of noise from switch mode power supplies. (I have ordered another couple.)

    BEC - Switch mode Screen10

    Sellers Specification:

    Brand new
    Size: approx. 42*24*11mm

    Output Voltage: 5V or 6V (Changeable with an output-voltage select switch)

    Continuous Output Current: 3 Amps

    Input: 5.5V-26V (2-6 cells lithium battery pack or 5-18 cells NiMh /NiCd battery)

    Fine workmanship and good performance.

    Easy to use.

    Long service life.



    Package included:

    1 x 3A RC UBEC Switch

    I have never had any Issues with them but i have never done any tests for noise. I assume these work so well because they have shielding, its not just a bare PCB.
