The nominal inductance is 600 µH with a tolerance of ±30%. The rated DC current is 2.5 A, and the maximum DC resistance is 0.09 Ω. The component operates within a temperature range of -40 °C to +125 °C and supports a rated voltage of 250 V AC.

Feature Summary

• Current-compensated design for power line applications
• Ring core construction using ferrite material
• Radial leaded termination for through-hole mounting

Applications

• Power line filtering
• EMI suppression in electronic equipment
• General purpose inductor circuits

Procurement Notes

Verify the specific suffix N020 against official TDK/EPCOS documentation to confirm terminal configuration and compliance status. Ensure the selected variant matches the required inductance and current ratings for the target application. Cross-reference datasheets for precise dimensional tolerances and thermal characteristics before integration.

Selection Notes

Select this component when a compact, high-current common mode choke is required for 250 V AC systems. The 2.5 A rating suits moderate power applications. Verify that the radial package fits the PCB layout constraints. Consider the operating temperature range if the environment exceeds standard limits.

Part Context
