PAD00x-T764 Series Push-Pull Isolation Transformer

Product catalog summary

Overview: The PAD00x-T764 Series Push-Pull Isolation Transformer is designed for applications requiring low-profile and small-size transformers. It complies with IEC 62368 standards and provides functional insulation for 400 Vrms continuous operation voltage. The operating temperature range is from -40°C to +125°C, and it is RoHS compliant.

Applications: This transformer is suitable for isolated RS-485/RS-232 power supplies, industrial automation, AC motor drives, smart metering, and solar inverters.

Electrical Specifications: At 25°C, the primary inductance is 475 µH with a turns ratio varying from 1:1.1 to 1:2. The maximum volt microseconds is 11 V-µS, and the isolation voltage is 3100 Volts RMS. The DCR max varies between 650 mΩ and 1000 mΩ depending on the model.

General Specifications: The transformer has a current rating of 350 mArms and a HI-POT primary/secondary rating of 3100 VAC/1 mA/2 s. It features functional insulation for a working voltage of 400 Vrms per IEC 62368, Material Group III, Pollution Degree 2. The moisture sensitivity level is 1.

Materials: The core is made of ferrite, the wire is copper, the case is DAP, and the terminal finish is Sn. Packaging is available with 800 pieces per 13-inch reel.

Soldering Profile: The soldering temperature profile includes a peak temperature (TP) of 250 ± 3°C for a maximum of 10 seconds, with a ramp-up rate of 3°C/s max and a ramp-down rate of 6°C/s max.

Ordering Information: The model number indicates the power rating, core type, dimensions, turns ratio, and PCB type. For example, PAD001-T764117S indicates a 1 W power rating, toroid core, dimensions of 7.10 x 6.55 x 4.0 mm, a turns ratio of 1:1.7, and SMD PCB type.
