Arrays, Signal Transformers Procurement Notes

Verify the specific datasheet version for the PA2494HL to confirm exact physical dimensions and terminal configurations. Ensure compatibility with your PCB footprint design, as the rectangular package requires precise alignment. Cross-reference the saturation current rating against your peak load requirements to prevent performance degradation under heavy transient conditions.

Arrays, Signal Transformers Selection Notes

Select this component when designing multi-phase converters that require identical inductance values across phases without magnetic coupling. The high saturation current capability makes it suitable for applications demanding significant transient response. Consider the operating temperature range of -40°C to +130°C for environments with extreme thermal variations.

Arrays, Signal Transformers Part Context

This part belongs to Pulse Electronics' SMT Power Inductors series, specifically designed for high-current applications. The PA2494HL variant offers a four-coil configuration, distinguishing it from single or dual-coil counterparts in the same family. It addresses the need for compact, high-performance inductive components in modern power electronics.

Arrays, Signal Transformers Replacement Considerations

Consult official Pulse Electronics documentation for verified substitute part numbers. Ensure any replacement maintains the 0.35 µH inductance, 80 A saturation current, and compatible package dimensions to preserve circuit functionality.
