PLA10AS7720R7D2B

Common Mode Chokes Overview

The Murata PLA10AS7720R7D2B is a two-line common mode choke designed for through-hole mounting. It features an inductance of 7.7 mH and supports a maximum current of 0.7 A with a rated voltage of 250 V. The component exhibits a maximum DC resistance of 950 mOhms and operates within a temperature range of -25 °C to +60 °C. Its physical length is 18 mm, providing a compact solution for noise suppression in electronic circuits.

Common Mode Chokes Feature Summary

• Provides effective common mode noise attenuation for differential signal lines
• Supports high voltage isolation up to 250 volts
• Utilizes through-hole construction for robust mechanical attachment

Common Mode Chokes Applications

• AC line filtering in power supply inputs
• Noise suppression in industrial control systems
• EMI reduction in consumer electronics interfaces

Common Mode Chokes Procurement Notes

Verify the specific suffix D2B against official Murata documentation to confirm lead frame material and plating specifications. Ensure the through-hole footprint dimensions match the target PCB layout. Confirm that the 0.7 A current rating meets the operational requirements of the intended circuit without saturation. Cross-reference the 950 mOhm DC resistance limit with thermal management calculations.

Common Mode Chokes Selection Notes

Select this component when through-hole mounting is required for mechanical stability in high-voltage applications. The 7.7 mH inductance offers significant impedance at common mode frequencies while maintaining low series resistance. Consider the 250 V rating for mains-connected or isolated secondary side applications where higher voltage tolerance is necessary compared to standard low-voltage chokes.

Common Mode Chokes Part Context

This part belongs to Murata's PLA series of common mode chokes, which are engineered for general-purpose EMI suppression. The series utilizes ferrite core technology optimized for broadband noise reduction. The PLA10AS7720R7D2B specifically targets applications requiring moderate inductance values with through-hole compatibility for assembly processes that do not support surface-mount technology exclusively.

Common Mode Chokes Replacement Considerations

The PLA10AS7720R7D2M is a documented variant within the same product family. Verify if the M suffix indicates a difference in termination plating or packaging format rather than electrical performance changes before substitution.
