Overview
The Bourns 7354-H-RC is a through-hole common mode choke designed for EMI suppression in differential signal lines. It features an inductance of 8 mH and a maximum current rating of 400 mA. The DC resistance (DCR) is limited to a maximum of 2 Ohms. The component operates within a temperature range of -55°C to +105°C. Its physical dimensions are 0.669 inches in length, with a radial lead mounting type.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Radial through-hole construction for standard PCB integration
- Rated for operation in high-temperature environments up to 105°C
Applications
- Differential signal line EMI suppression
- Data communication interfaces
- Industrial control systems
Procurement Notes
Verify the complete part number including suffixes such as 'RC' which indicates RoHS compliance. Confirm that the 400mA current rating and 8mH inductance meet specific circuit requirements. Ensure the through-hole package fits the target PCB layout. Cross-reference datasheet specifications for thermal rise characteristics under rated load conditions.
Selection Notes
Select this component when differential line filtering is required without significant signal attenuation. The 8mH value offers substantial impedance to common mode noise. The 400mA rating suits low-power signal applications rather than power delivery. Consider the 2 Ohm DCR impact on signal integrity if applicable. The wide temperature range supports harsh environment deployments.
Part Context
This component belongs to the Bourns 7300 series of radial common mode chokes. These components are engineered specifically for suppressing electromagnetic interference in sensitive electronic circuits. The series provides reliable performance across various industrial and commercial applications requiring robust noise filtration.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative manufacturers or series.
