Procurement Notes

Verify the specific datasheet version from Signal Transformer or authorized distributors to confirm current RoHS compliance status and exact pinout configurations. Ensure the procurement channel is an authorized partner to guarantee product authenticity and traceability. Cross-reference the part number with official manufacturer catalogs to validate availability and technical specifications before finalizing orders.

Selection Notes

Select this transformer when a 36 VA capacity is required with dual primary voltage support. The center-tapped secondary allows for full-wave rectification circuits. Verify that the physical dimensions and lead spacing match the target PCB layout. Confirm that the operating frequency range of 50/60 Hz aligns with the system's power source requirements.

Part Context

The DST-7-48 belongs to the DST series of laminated core transformers manufactured by Signal Transformer. This series is engineered for robust performance in standard power conversion tasks. The component utilizes traditional wound core technology rather than planar designs, offering high reliability for through-hole assembly processes in industrial and commercial electronics.

Replacement Considerations

Direct replacements must match the 36 VA rating, 115/230V primary, and 48V CT secondary specifications. Verify equivalent pinouts and mechanical footprint compatibility. Consult Signal Transformer documentation for approved alternative part numbers within the same series or comparable models from other manufacturers meeting identical electrical standards.
