PQ60120EML04 Datasheet, PDF (13/14 Pages) SynQor Worldwide Headquarters – Eighth-brick DC/DC Converter

Technical Specification
Input: 35-75 V
Output: 12 V
Current: 4 A
Package: Eighth-brick
Keep Out Areas:
Component Keep Out Area: Keep out areas for components not
referenced to the Primary circuit are shown in shaded areas in
Figure G. The keep out areas shown are consistent with UL's
requirements for Basic Insulation of 0.04" (40 mils) for Pollution
degree 2. User should consult UL standards for other insulation
classes and operating environments.
For applications that require mounting parts BELOW the
PowerQor module, one should be aware of potential high levels
of electromagnetic interference, in addition to safety keep out.
Users are advised to consult SynQor Applications engineering in
such applications.
Copper Keep Out Area: Keep out areas shown in Figure G are
to be observed for Top layer copper traces and vias. Internal lay-
ers buried one or more layers may be exempt, depending on the
PCB material grade and thickness. Users are advised to consult
UL standards for details.
All layers including top and bottom, are subject to the keep out
areas shown around Primary pins of PowerQor module. Actual
keep outs along the surface (Creepage) may vary depending on
the PCB material CTI. Users are advised to consult UL standards
for details.
Bridging Components: Bridging components like EMI filter capac-
itors required to be placed as close as possible to the PowerQor
module for optimum performance must observe the
clearance/creepage requirements of 0.04"(40 mils) between
pads to maintain compliance to UL standards for the overall
power system.
Note: Referenced keep out widths are adequate to withstand UL's
Basic Insulation Dielectric strength tests for approved PCB mate-
rials. Applications requiring Double or Reinforced insulation must
double the keep out widths shown in Figure G. Keep out areas
shown have standard margins above UL's minimum requirements.
