The component supports a maximum DC current of 7 A and exhibits a maximum DC resistance of 2.8 mΩ. Its impedance is rated at 1.4 kΩ, with a self-resonant frequency of 2.5 MHz. The unit operates within a temperature range of -40°C to +125°C and measures 13 mm in length, 13 mm in width, and 5.6 mm in height.

Common Mode Chokes Feature Summary

• Surface mount toroidal construction for compact PCB integration
• Dual-line configuration for effective common mode noise suppression
• Low DC resistance to minimize power loss in high-current applications

Common Mode Chokes Applications

• Electromagnetic interference (EMI) filtering in electronic devices
• Signal integrity protection in data transmission lines
• Power supply input/output noise reduction

Common Mode Chokes Procurement Notes

Verify the specific datasheet version against the manufacturing date code, as product change notifications may alter physical or electrical characteristics. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to final design approval. Ensure the ordering quantity aligns with the standard factory pack size to avoid partial reel issues.

Common Mode Chokes Selection Notes

Select this component when a low-profile, high-current common mode choke is required for surface-mount assembly. The 7 A rating and 2.8 mΩ DCR make it suitable for power lines where efficiency is critical. Compare the 61 µH inductance value against circuit requirements to ensure adequate noise attenuation at the target frequency without affecting signal integrity.

Common Mode Chokes Part Context

This part belongs to the PA27XX series of SMT common mode chokes from Pulse Electronics, designed for up to 20 A applications. The series utilizes toroidal technology to provide robust performance in a small footprint. The PA2747NL specifically targets mid-range current applications requiring precise filtering characteristics.
