7356-H-RC

Overview

The Bourns Inc. 7356-H-RC is a through-hole common mode choke designed for signal line noise suppression. It features an inductance of 22 mH and supports a maximum DC current rating of 270 mA. The component exhibits a maximum DC resistance (DCR) of 4 Ohms, ensuring minimal signal attenuation in low-current applications. It operates reliably within a temperature range of -55°C to +105°C. The physical dimensions are 0.669 inches in length, with a two-line configuration optimized for standard PCB mounting.

Feature Summary

• Provides effective common mode noise rejection for differential signal lines
• Supports high inductance values suitable for EMI filtering applications
• Designed for robust through-hole mounting on printed circuit boards

Applications

• Signal line interference suppression in electronic equipment
• EMI filtering for data communication interfaces
• Noise reduction in consumer electronics signal paths

Procurement Notes

Verify the specific suffix 'RC' against the manufacturer's official documentation to confirm compliance with RoHS directives and halogen-free status. Ensure that the 270 mA current rating aligns with the operational requirements of the target circuit to prevent saturation or excessive thermal rise during continuous use.

Selection Notes

Select this component when a high inductance value of 22 mH is required for low-frequency noise attenuation. The 4 Ohm DCR limit makes it suitable for sensitive signal lines where voltage drop must be minimized. Verify that the through-hole package fits the available PCB footprint and that the operating temperature range covers the environmental conditions of the end application.

Part Context

This component belongs to Bourns' passive filter portfolio, specifically within the common mode choke category. It is engineered for general-purpose noise suppression rather than high-power energy storage. The design focuses on maintaining signal integrity while attenuating unwanted electromagnetic interference in compact electronic assemblies.

Replacement Considerations

Consult the official Bourns datasheet for direct cross-reference part numbers. Ensure any substitute maintains the 22 mH inductance, 270 mA current rating, and 4 Ohm DCR specifications to preserve circuit performance.
