CRR32NP-02A

Common Mode Chokes Overview

The CRR32NP-02A is a signal common mode choke manufactured by Sumida America Components Inc. It features a horizontal surface mount package with four PCB pads and measures 3.80mm in length, 3.00mm in height, and 3.00mm in width. The component provides an impedance of 800 Ohms at 100 MHz and supports a maximum current rating of 400 mA. Its DC resistance is specified at 500 mOhms. Designed for signal line filtering applications, it operates within standard industrial temperature ranges and complies with RoHS directives.

Common Mode Chokes Feature Summary

• Horizontal surface mount configuration optimized for space-constrained circuit boards
• High impedance performance at 100 MHz for effective noise suppression
• Compact footprint suitable for dense layout designs

Common Mode Chokes Applications

• Signal line filtering in electronic circuits
• Noise suppression in data transmission lines
• EMI reduction in compact consumer electronics

Common Mode Chokes Procurement Notes

Verify the specific impedance value and current rating against the official Sumida datasheet before integration. Confirm that the horizontal package dimensions align with the target PCB footprint. Ensure compliance with project-specific environmental standards such as RoHS requirements. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Common Mode Chokes Selection Notes

Select this component when high impedance at 100 MHz is required for signal integrity in small form factors. The low DC resistance helps minimize voltage drop in sensitive signal paths. Consider the horizontal profile if vertical clearance is limited. Evaluate thermal performance based on the 400 mA current rating under expected operating conditions.

Common Mode Chokes Part Context

This component belongs to the CRR32 series of signal common mode chokes from Sumida. The series includes variants like CRR32NP-05A and CRR32NP-07A, which offer different impedance characteristics while maintaining similar physical dimensions. These parts are designed for general-purpose signal line protection in portable and automotive electronics.

Common Mode Chokes Replacement Considerations

Compatible substitutes include other Sumida CRR32 series parts such as CRR32NP-05A or CRR32NP-07A, provided their impedance values match the design requirements. Verify pin compatibility and mechanical fit before substitution.
