Technical Specification Quarter -brick Tera Series w/ Baseplate High Efficiency, Isolated DC/DC Converter, with Baseplate This technical addendum contains additional specifications for the baseplated version of the PowerQor Tera Top View quarter-brick series of converters. This unit is manufac- Bottom View tured by adding an industry standard size baseplate to the non-baseplated quarter-brick converter using standard mounting techniques. The baseplated version allows for PQ60xxxQTBxx optional heatsinking in severe thermal environments or DC/DC Converter for mounting to a cold plate. Please refer to the QTAxx specification sheets for all specifications that are not included in this addendum. 2.32 (58.9) MECHANICAL DIAGRAM 0.22 (5.6) 0.23 (5.8) 1.86 (47.2) 0.44 (11.2) 0.498 + 0.025 Side View 0.150 0.300 0.450 (12.65 + 0.64) (11.43) (3.81) (7.62) 0.600 (15.24) 0.300 (7.62) 0.600 (1.52 +.55/-0.81) Bottom side Clearance 1.030 (15.24) (26.16) 0.060 +.022/-.032 Lowest Component See Note 12 Load Board Top View 0.145 (3.68) See Note 6 Pin farside typical NOTES 0.15 1) M3 screws used to bolt unit’s baseplate to other surfaces (such as heatsink) must not exceed 0.100” (2.54 mm) depth below the surface of the baseplate 2) Applied torque per screw should not exceed 6in-lb.

Doc.# 005-2QTBXXC Rev. B 2/9/04 Page 1 Technical Specification Quarter -brick Tera Series w/ Baseplate ATTACHING HEATSINKS PART NUMBERING SYSTEM Follow the guidelines given below when attaching a heatsink to a PowerQor converter with baseplate. The part numbering system for SynQor’s PowerQor DC/DC converters follows the format shown in the example below. For a complete listing of available part numbers, please refer to the SynQor web site. 1) A thermal interface material is required to assure proper heat transfer from the baseplate to the heatsink. Thermal grease may be used, or materials such as Thermalloy's Grafoil or Bergquist's HiFlow and SoftFace. Other similar products are available from many heatsink manufacturers. 2) Use four M3 threaded machine screws for attachment. The length of the screw will depend on the thickness of the heatsink baseplate. The maximum permissible screw length below the top surface of the baseplate is not to exceed 2.54mm (0.10") in order to prevent damage to any internal components. 3) The screws should be tightened with a torque suitable to get a tight fitting of the heatsink against the thermal interface material and the baseplate. The applied torque per screw should not exceed 0.7 Nm (6 in-lb). Contact SynQor technical support for additional information.

PQ 60 033 Q T B 35 N K S Options Output Current Thermal Design Performance Level Package Size Output Voltage Input Voltage Product Family The first 12 characters comprise the base part number and the last 3 characters indicate available options. Selected PowerQor modules are available with a baseplate. Before ordering basplated modules, one should consult the factory to ensure that the specific product is available in a baseplated version. The Tera series of single output quarterbricks that have a baseplate should be designated with the letter “B” as the 10th character in the full 15 character part number. The other characters in the part number would follow the same format as a non-baseplated unit to indicate the desired input and output voltage, package size, performance level, rated current, enable logic, pin length and feature set. When ordering SynQor converters, please ensure that you use the complete 15 character part number.
