This product family provides up to 100 watts of power or 30A of th output current in the 1/16 brick form factor (1.3x0.90) and pinout. SOLDERING METHOD With creative design technology and optimization of component Hand soldering placement, these converters possess outstanding electrical and Wave soldering thermal performance, as well as extremely high reliability under highly Reflow soldering (MSL of rating 3) stressful operating conditions. Typical efficiency of the 12V/8.3A module is greater than 92.0%. All modules are protected from abnormal input/output voltage, current, and temperature conditions. APPLICATIONS For lower power needs, but in a similar small form factor, please check Optical Transport out Delta V36SE (50W), S48SP (36W or 10A) and S36SE (17W or 5A) Data Networking series standard DC/DC modules.
