Procurement Notes

Verify the specific datasheet version to confirm insulation class and environmental ratings before integration. Ensure mechanical clearance accommodates the 41.3 mm height dimension. Confirm that the 6-terminal pin configuration matches the target PCB footprint. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a 20VA isolated transformer is needed for 12V secondary output. It is suitable for designs requiring 4000Vrms isolation between windings. Consider the through-hole mounting style and physical size constraints. Verify input voltage requirements match the available 115V or 230VAC supply lines.

Part Context

This part belongs to the CL2 series of power transformers from Signal Transformer. The series includes various voltage and wattage configurations for both printed circuit and chassis mount options. The CL2-20-12 specifically addresses the need for moderate power isolation in compact board-mounted form factors.

Replacement Considerations

Consult official manufacturer substitution lists for verified equivalents. Generic replacements may differ in isolation voltage, thermal performance, or physical envelope. Do not assume interchangeability without verifying electrical parameters and mounting hole patterns against the original specification sheet.
