Overview
The Bourns 7514-RC is a common mode inductor designed for EMI filtering applications. It features a maximum current rating of 1A and a DC resistance (DCR) of 490mOhm. The component has an AC voltage rating of 250V and operates within a temperature range of -55°C to 105°C. It utilizes a through-hole mounting type, ensuring secure integration into printed circuit boards.
Feature Summary
- Provides common mode inductance for electromagnetic interference suppression
- Supports through-hole mounting for robust PCB integration
- Rated for high AC voltage environments up to 250V
Applications
- Common mode chokes and filters
- EMI filter circuits
- Signal line protection
Procurement Notes
Verify the specific datasheet version when sourcing, as component specifications may be subject to revision. Confirm that the through-hole package dimensions align with your board layout requirements. Ensure the operating temperature range meets your environmental constraints. Cross-reference the manufacturer's lifecycle status to confirm availability for long-term production needs.
Selection Notes
Select this component when a 1A current rating and 490mOhm DCR are required for common mode noise reduction. The 250V AC rating makes it suitable for mains-connected or higher voltage signal lines. Consider the through-hole form factor if surface mount alternatives are insufficient for mechanical stability or thermal dissipation in the target application.
Part Context
The 7514-RC belongs to the Bourns 7500 Series of common mode inductors and EMI filters. This series includes related part numbers such as 7504-RC, 7510-RC, and 7516-RC, offering various inductance values for different filtering requirements. The product life status indicates potential demand fluctuations, requiring careful inventory planning.
Replacement Considerations
Direct substitutes within the same series include 7504-RC, 7510-RC, 7516-RC, 7506-RC, 7512-RC, and 7518-RC. Verify that alternative part numbers match the required inductance and current ratings before substitution.
