CSLF4D17NP-781

Common Mode Chokes Overview

The CSLF4D17NP-781 is a hybrid power inductor manufactured by Sumida America Components Inc. It functions as a common mode choke with an impedance of 780 Ohms at 100 MHz. The component supports a current rating of 1A and features a DC resistance (DCR) of 50mOhm. It is designed for surface mount technology (SMD) applications, utilizing a 4-pin configuration to provide electromagnetic interference filtering in electronic circuits.

Common Mode Chokes Feature Summary

• Surface mount construction for automated assembly integration
• Common mode noise suppression capability
• Hybrid inductor design combining power and filtering functions

Common Mode Chokes Applications

• Electromagnetic interference filtering in consumer electronics
• Signal line protection in industrial control systems
• Power supply input/output noise reduction

Common Mode Chokes Procurement Notes

Verify the specific impedance value of 780 Ohms at 100 MHz against circuit requirements. Confirm the 1A current rating and 50mOhm DCR specifications match the design constraints. Ensure the 4-pin SMD package footprint aligns with the PCB layout. Cross-reference the manufacturer part number CSLF4D17NP-781 with official Sumida documentation to confirm availability and lifecycle status before ordering.

Common Mode Chokes Selection Notes

Select this component when a compact surface mount solution is required for common mode noise attenuation. The 780 Ohm impedance at 100 MHz targets high-frequency interference suppression. The 1A current handling capacity suits moderate power applications. Verify that the 4-pin SMD form factor fits within the available board space and thermal management guidelines.

Common Mode Chokes Part Context

This component belongs to the CSLF4D17NP series of hybrid power inductors from Sumida. The series includes variants such as CSLF4D17NP-391 and CSLF4D17NP-212, which offer different impedance levels. These components are engineered for applications requiring combined power inductance and common mode choking in a single surface mount package.

Common Mode Chokes Replacement Considerations

Official substitutes include CSLF4D17NP-391 and CSLF4D17NP-212 from the same Sumida series. Verify impedance and current ratings match application needs before substitution.
