The industry quarter-pack size of 2.3" x 1.5" x 0.5" coupled with 90% efficiency is an industry high-density breakthrough. These converters utilize V Series high density technology. This technology has been featured in our highly efficient VKP and VKA Series now successfully in use worldwide. The very high 90% efficiency minimizes the requirement for heat-sinking and the low output ripple minimizes the need for additional filtering. For maximum flexibility, power can be traded between outputs as required. The VSX75C Series feature virtually all of the options required by design engineers but not at the competition’s typical additional price for each option. This multitude of features are standard on the VSX75C Series.

They are not intended to be subject to surface mount processes under any circumstances. The normal wave soldering process can be used with these devices where the device is subjected to a maximum wave temperature of 260°C for a period of no more than 10 seconds. Within this time and temperature range, the integrity of the device’s plastic body will not be compromised and internal temperatures within the converter will not exceed 175°C. Care should be taken to control manual soldering limits identical to that of wave soldering. www.murata-ps.com Technical inquiries - email: [email protected], tel: 508 339 3000 TDC_VSX75MD35C.B01 Page 3 of 6 VSX75MD35C 75 Watt Dual Output Quarter Brick DC/DC Converter GRAPHS EFFICIENCY VS.
