• Utilizes ultra-small ceramic-based surface mount technology for space-constrained designs
• Non-polarized construction simplifies PCB layout and assembly processes

Common Mode Chokes Applications

• Mobile phones
• Tablets
• Portable wearable devices
• Consumer electronics with high-speed differential interfaces

Common Mode Chokes Procurement Notes

Verify the specific impedance value (35 Ohms) and current rating (70 mA) against your circuit requirements before ordering. Confirm that the 0302 metric footprint matches your board design. Ensure the operating temperature range of -45°C to +85°C meets your environmental specifications. Check RoHS compliance status if required by your manufacturing standards.

Common Mode Chokes Selection Notes

Select this component when shielding high-speed differential signals from common mode interference without distorting the signal integrity. The low DC resistance ensures minimal voltage drop across the lines. The small form factor allows integration into densely packed consumer electronics where space is limited compared to larger inductive filters.

Common Mode Chokes Part Context

This part belongs to the Littelfuse LPF series of common mode chokes. These components are engineered to meet the stringent requirements of modern high-speed serial data interfaces. The series offers various impedance options to suit different frequency attenuation needs while maintaining a consistent ultra-compact ceramic package profile.

Common Mode Chokes Replacement Considerations

Consider the LPF090703A250TG for applications requiring 25 Ohms impedance. Other LPF series variants may be suitable if different impedance or current ratings are needed. Verify pin compatibility and thermal characteristics when substituting.
