Description
The Bel x7AH-03C500 is a part of the low cost non-isolated dc/dc converter series. The modules use a SMD or
SIP package for ease of layout and space savings. The output is closely regulated and the efficiency is typically
90% at full load.

Note:
The input reflected ripple current is measured with simulated source impedance of 500 nH, 5 Hz to 20
MHz; Use one 270 uF/16 V capacitor with ESR = 0.018 ohm max. at 100KHz at 25
