Overview
The Delevan CM6594R-105 is a surface-mount common mode filter choke designed for PCB integration. It features an unshielded ER core with four windings and offers an inductance of 1000 uH with a 25% tolerance. The component supports a maximum DC current of 380 mA and exhibits a maximum DC resistance of 1.19 ohms. Its physical dimensions are 0.465 inches in length, 0.405 inches in width, and 0.235 inches in height.
Feature Summary
- Utilizes an unshielded ER core structure with four windings for effective common mode noise suppression.
- Designed for direct surface-mount technology (SMT) installation on printed circuit boards.
Applications
- Electronic circuits requiring common mode noise filtering
- Signal integrity enhancement in sensitive data lines
- Power supply input/output stages
Procurement Notes
Verify the specific electrical parameters against the official manufacturer datasheet before procurement. Confirm that the 1.19 ohm DC resistance and 380 mA current rating align with your circuit requirements. Ensure compatibility with SMT assembly processes and check for any RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a high-inductance common mode choke is needed for surface-mount applications. The 1000 uH value provides significant attenuation for common mode interference. Consider the 1.19 ohm DC resistance impact on voltage drop and the 380 mA current limit to ensure reliable operation under expected load conditions without saturation.
Part Context
This part belongs to the Delevan CM6594R series of common mode chokes. It shares the same physical footprint and mounting style as other variants in the series, such as the CM6594R-154 and CM6594R-503, allowing for potential design flexibility within the same mechanical constraints while varying inductance values.
Replacement Considerations
Direct substitutes within the same series include CM6594R-154 and CM6594R-503. These parts share identical dimensions and mounting characteristics but differ in inductance and current ratings. Verify that the alternative inductance value meets the specific filtering requirements of the application.
