7353-H-RC

Overview

The Bourns 7353-H-RC is a vertical mount common mode choke from the 7300 series, designed for through-hole installation. It features a 5 mH inductance measured at 1 kHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance (DCR) of 1 Ohm. It operates within a temperature range of -55°C to +105°C. Physical dimensions are 17 mm in length, 11 mm in width, and 17 mm in height.

Feature Summary

• Vertical mounting configuration for space-efficient PCB integration
• Radial leaded termination style for standard through-hole assembly
• Designed for EMI suppression on differential signal lines

Applications

• EMI filtering for differential data communication interfaces
• Noise suppression in industrial control signal circuits
• Common mode noise reduction in consumer electronics power supplies

Procurement Notes

Verify the specific suffix 'H' against the required datasheet revision, as it denotes the vertical orientation variant within the 7300 series. Confirm that the 500 mA current rating aligns with the peak operational loads of the target circuit to prevent saturation. Ensure the 1 Ohm DCR does not introduce excessive voltage drop in low-voltage signal paths. Cross-reference the physical footprint dimensions with the PCB layout to guarantee mechanical fitment during assembly.

Selection Notes

Select this component when vertical mounting is preferred over horizontal configurations to save board area. The 5 mH value provides effective attenuation for high-frequency noise while maintaining a compact form factor. Consider the 500 mA current limit when designing for higher power applications, as saturation may occur beyond this threshold. The wide operating temperature range makes it suitable for environments subject to thermal fluctuations without derating requirements.

Part Context

This part belongs to the Bourns 7300 series of radial common mode chokes. The series offers various inductance values and current ratings tailored for different EMI suppression needs. The 7353-H-RC specifically utilizes the 'H' designation to indicate its vertical construction, distinguishing it from other orientations in the same family. These components are engineered for reliable performance in general-purpose electronic equipment requiring robust noise filtering.

Replacement Considerations

Check for direct substitutes within the 7300 series that share identical electrical parameters but differ only in mounting orientation or packaging. Verify compatibility with existing footprints if considering alternative manufacturers offering similar radial common mode chokes with matching 5 mH inductance and 500 mA ratings.
