IF-30-30

Power Transformers Overview

The IF-30-30 is a semi-toroidal power transformer from the Signal Transformer LP series. It features dual primary windings rated for 115VAC and 230VAC input. The secondary configuration provides 30VCT output, supporting parallel operation at 15V with 2A current or series operation at 30V with 1A current. The unit has a 30VA power rating and utilizes a Class B insulation system. Key electrical specifications include a 4000Vrms hipot dielectric strength between windings. The component is designed for through-hole mounting on printed circuit boards.

Power Transformers Feature Summary

• Dual primary winding design accommodating 115V and 230VAC line voltages
• Flexible secondary configuration allowing series or parallel connection options
• High dielectric isolation strength of 4000Vrms between windings
• Class B insulation system for thermal stability

Power Transformers Applications

• General purpose AC power supply circuits
• Industrial control panel power distribution
• Audio equipment power stages requiring isolated transformers
• Test and measurement instrument internal power regulation

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and pinout compatibility with your PCB layout. Ensure the required voltage isolation class meets your safety regulatory standards. Confirm that the through-hole lead spacing matches your manufacturing capabilities. Check for any RoHS compliance documentation if environmental regulations apply to your assembly process.

Power Transformers Selection Notes

Select this model when a 30VA capacity is sufficient for the load requirements. Choose the IF-30-30 over higher wattage variants to save board space and reduce cost if the application does not demand greater power. Consider the semi-toroidal shape for lower magnetic leakage compared to standard laminated cores. Verify that the 4000Vrms isolation is adequate for the specific safety barriers required in the final product design.

Power Transformers Part Context

This component belongs to the LP series of low-profile flat head transformers manufactured by Signal Transformer (Bel Fuse). The series is characterized by compact semi-toroidal construction designed for efficient use of vertical clearance on circuit boards. These transformers are engineered for reliability in continuous duty applications within electronic systems requiring galvanic isolation.

Power Transformers Replacement Considerations

Direct substitutes may include other 30VA semi-toroidal transformers with identical 115/230V primary and 30VCT secondary ratings. Verify that replacement parts maintain the same 4000Vrms isolation voltage and physical footprint. Cross-reference pin configurations to ensure compatibility without rewiring.
