7355-V

Overview

The Bourns 7355-V is a vertical mount common mode choke belonging to the 7300 series. It features radial termination and supports a maximum DC current of 350 mA with a maximum DC resistance of 2.2 ohms. The inductance is specified at 10 mH. The component 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 circuit board integration
• Radial leaded termination style for through-hole assembly processes
• Single-channel design optimized for common mode noise suppression

Applications

• Signal line filtering in electronic equipment
• Power supply input stages requiring common mode interference reduction
• Data communication interfaces needing EMI mitigation

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as RC may indicate RoHS compliance or specific packaging distinctions. Confirm that the vertical form factor aligns with the mechanical constraints of the target PCB layout. Ensure the 350 mA current rating meets the operational requirements of the application circuit to prevent saturation or excessive heating during normal use.

Selection Notes

Select this component when a vertical orientation is required to minimize footprint area on the printed circuit board. The 10 mH inductance value provides effective attenuation for high-frequency noise while maintaining a low profile. Consider the 2.2 ohm DC resistance impact on voltage drop if used in low-voltage power lines. The wide operating temperature range ensures reliability in demanding environmental conditions.

Part Context

This part belongs to the Bourns 7300 series of common mode chokes. The series offers various inductance values and current ratings tailored for different filtering needs. The 7355-V specifically addresses applications requiring a compact, vertically mounted solution with moderate current handling capabilities for signal integrity protection.

Replacement Considerations

Cross-reference with other Bourns 7300 series parts for alternative inductance or current ratings. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers to ensure mechanical fit and electrical performance equivalence.
