DST4-24B18

Overview

The DST4-24B18 is a low-frequency power transformer manufactured by Pulse Electronics, designed for board-mount applications using a split bobbin and laminated core construction. It features dual primary windings rated for 115V and 230V inputs. The secondary configuration provides parallel output at 12V with a maximum current of 500mA, or series output at 24V with a maximum current of 250mA. This component utilizes a horizontal plug-in mounting style suitable for through-hole assembly.

Feature Summary

• Utilizes a split bobbin and laminated core structure for efficient magnetic coupling
• Supports versatile input voltage configurations via dual primary windings
• Offers configurable secondary outputs in either parallel or series arrangements

Applications

• Low frequency power conversion circuits
• Board mount power supply units
• Equipment requiring isolated AC voltage transformation

Procurement Notes

Verify the specific datasheet version to confirm exact physical dimensions and pinout compatibility before integration. Ensure that the thermal management strategy aligns with the transformer's power dissipation characteristics under full load conditions. Confirm regulatory compliance status such as RoHS requirements against project specifications. Cross-reference the manufacturer part number with distributor catalogs to ensure availability and correct ordering suffixes are applied.

Selection Notes

Select this model when a robust laminated core transformer is required for low-frequency operations. The dual primary winding design allows flexibility for different regional line voltages. Consider the physical size constraints of the PCB layout due to the horizontal plug-in form factor. Evaluate the current handling capabilities of the secondary windings to ensure they meet the load requirements in both parallel and series modes.

Part Context

This component belongs to the DST4 series of power transformers from Pulse Electronics. The series is characterized by its use of laminated cores and split bobbin designs, which are common in general-purpose power applications. These transformers are typically used in industrial and commercial equipment where reliable isolation and voltage transformation are necessary.

Replacement Considerations

Check for direct substitutes within the same series or similar electrical ratings. Verify that any replacement maintains the same core type, winding configuration, and physical footprint. Ensure that the replacement part supports the required input and output voltage/current combinations.
