Technical Diagrams and Descriptions
Ripple & Noise Test Setup
The diagram illustrates the test setup for ripple and noise measurement. It shows the input voltage (Vin) connected to the power supply, with output voltage (Vout) measured across a load. A parallel combination of a 47μF capacitor and a 0.1μF capacitor is placed across the output terminals. A ground lead is also indicated.
Derating Curve
The derating curve graph plots the Load percentage on the Y-axis against Temperature (°C) on the X-axis. The curve starts at 120% load at -25°C, decreases linearly to 100% load at approximately 60°C, and continues to decrease to 80% load at 85°C. This indicates that the output load capacity is reduced at higher temperatures.
Mechanical Specification
The mechanical specification section provides dimensional drawings of the AC-DC converter. The main body dimensions are approximately 35.7mm (Length) x 25.0mm (Width) x 19.0mm (Height). A detailed view shows pin assignments: Pin 1 is Vin(L), Pin 2 is Vin(N), Pin 3 is +Vout, and Pin 4 is -Vout. The drawing also indicates mounting hole details and clearances.
Package Information
The package section shows the dimensions of the product in its packaging. The unit is specified in millimeters (mm). A tube contains 13 pieces, with a tube length of 520±2mm. The overall dimensions of the product package are approximately 35.7mm x 25.0mm x 19.0mm.
