ADH20020

Power Transformers Overview

The ADH20020 is a power transformer from the Zettler Magnetics ADH200 series, designed for through-hole mounting. It features a dual primary winding configuration supporting 115V and 230V inputs. The secondary side offers dual windings with parallel output of 110mA or series output of 55mA at 10V and 20V respectively. Rated at 1.1VA maximum power, it provides 4200V isolation voltage. The unit utilizes PC pin termination and measures approximately 41.28mm in length by 36.45mm in width.

Power Transformers Feature Summary

• Dual primary and secondary winding configurations allow flexible input voltage selection and output current/voltage scaling.
• High isolation voltage rating ensures safety compliance for general purpose applications.
• Through-hole mounting style with PC pin termination facilitates standard PCB assembly processes.

Power Transformers Applications

• General purpose AC to DC power supply circuits
• Industrial control equipment requiring isolated power stages
• Consumer electronics utilizing laminated core transformers

Power Transformers Procurement Notes

Verify the specific datasheet revision and electrical tolerances against your design requirements before ordering. Confirm that the through-hole footprint dimensions match your PCB layout constraints. Ensure the operating frequency range aligns with your system's 50/60Hz specification. Check for any RoHS compliance documentation if required by your manufacturing standards.

Power Transformers Selection Notes

Select this component when a 1.1VA isolated power source is needed for low-power applications. The dual secondary options provide flexibility for different voltage rails without changing the transformer model. Consider the physical size constraints as the laminated core construction requires specific clearance. Verify that the 4200V isolation meets the safety regulations applicable to your end product.

Power Transformers Part Context

This part belongs to the ADH200 series of power transformers manufactured by Zettler Magnetics. The series includes various ratings such as ADH20010 and ADH20024, sharing similar form factors but differing in power capacity. These transformers are commonly used in applications where cost-effective, reliable isolation is required for mains-powered devices.

Power Transformers Replacement Considerations

Cross-reference with other ADH200 series variants like ADH20010 or ADH20024 if power requirements differ. Ensure any substitute maintains the same 115V/230V primary compatibility and through-hole package dimensions. Verify that the replacement part meets the same 4200V isolation and 1.1VA rating specifications.
