Procurement Notes

Verify the specific ordering suffix to confirm packaging type, as the base part number may correspond to different reel quantities or tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability varies by region and channel. Ensure the selected variant matches the required surface-mount footprint and thermal characteristics for the target application environment.

Selection Notes

Select this component when a dual-channel, shielded transformer with 75-ohm impedance matching is required for surface-mount designs. The 1:1 ratio makes it suitable for direct signal coupling without gain modification. Consider the physical size constraints and operating temperature range to ensure compatibility with the PCB layout and environmental conditions of the final assembly.

Part Context

This component belongs to the Pulse Electronics audio and signal transformer family, specifically engineered for RF and high-frequency signal processing. It serves as a critical interface element in systems requiring balanced line driving or receiving, offering reliable performance in consumer electronics and industrial communication devices where space efficiency and signal fidelity are paramount.

Replacement Considerations

Direct substitutes must match the 7.5 µH inductance, 75-ohm impedance, 1:1 ratio, and 12.7x6.99x5.08 mm SMD footprint. Verify that alternative components offer equivalent 1.5 kV isolation and dual-channel shielding to maintain circuit performance and safety standards.
