CPFC54-102C

Common Mode Chokes Overview

The CPFC54-102C is a surface-mount DC common mode choke coil manufactured by Sumida. It features an inductance of 1 mH at 100 kHz and a typical direct current resistance (DCR) of 200 mOhm. The component supports a rated current of 500 mA and utilizes a two-line configuration for signal filtering. Its physical dimensions are defined by a horizontal package with gull-wing terminals, measuring 9.5 mm in length, 5.65 mm in width, and 4.9 mm in maximum height.

Common Mode Chokes Feature Summary

• Provides common mode noise suppression for differential data lines
• Designed for surface-mount assembly on printed circuit boards
• Utilizes a compact horizontal footprint to conserve board space

Common Mode Chokes Applications

• Data line filtering in electronic equipment
• Signal integrity protection in communication interfaces
• Noise reduction in power supply input circuits

Common Mode Chokes Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure correct impedance and tolerance specifications. Confirm that the surface-mount package orientation matches the designator requirements. Ensure compliance with RoHS directives and check for any lead-free certification status required by the target market regulations before finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when a 1 mH inductance value is required for common mode noise attenuation at standard test frequencies. Evaluate the 500 mA current rating against the operational load to prevent saturation. Consider the 200 mOhm DCR impact on voltage drop within the circuit. Compare physical dimensions against available PCB real estate constraints to ensure proper fitment during layout.

Common Mode Chokes Part Context

This part belongs to the CPFC series of DC common mode chokes produced by Sumida America Components Inc. The series focuses on providing electromagnetic interference suppression for sensitive electronic circuits. The CPFC54 variant specifically denotes the physical size category within the broader product family, distinguishing it from other form factors offered by the manufacturer.

Common Mode Chokes Replacement Considerations

The CPFC54-102C may be substituted with other parts from the same CPFC54 series, such as the CPFC54-101C or CPFC54-103C, provided the inductance values align with the circuit requirements. Verify terminal compatibility and thermal characteristics when considering alternative manufacturers' equivalents.
