ECMT1V1717S-8R0-R

Common Mode Chokes Overview

The ECMT1V1717S-8R0-R is a common mode choke manufactured by Eaton Electronics, designed for through-hole PCB mounting. It features an inductance of 8 mH and supports a maximum DC current of 800 mA. The component has a maximum DC resistance of 1 Ohm and a self-resonant frequency of 456 kHz. It operates within a temperature range of -40°C to +125°C. This unshielded device belongs to the ECMT-R series and is supplied in bulk packaging.

Common Mode Chokes Feature Summary

• Provides common mode noise filtering for single-channel applications
• Designed for standard through-hole PCB mounting
• Operates reliably across a wide industrial temperature range

Common Mode Chokes Applications

• Electromagnetic interference suppression in electronic circuits
• Signal integrity protection in data transmission lines
• Power supply input filtering for noise reduction

Common Mode Chokes Procurement Notes

Verify the specific suffix '8R0' confirms the 8 mH inductance value, as other suffixes in the ECMT1V1717S series indicate different inductances such as 1 mH or 2 mH. Confirm that the 800 mA current rating meets the circuit requirements. Ensure the through-hole package dimensions are compatible with the target PCB layout before ordering.

Common Mode Chokes Selection Notes

Select this component when an 8 mH common mode choke is required for through-hole assembly. Compare against lower inductance variants like the 1R0 or 2R0 models if higher current capacity or lower impedance is needed. Verify that the 456 kHz self-resonant frequency aligns with the target noise spectrum. Ensure the unshielded design does not interfere with nearby sensitive components.

Common Mode Chokes Part Context

This part belongs to the Eaton ECMT-R series of common mode chokes. The series offers various inductance values ranging from 1 mH to 8 mH within the same physical footprint. These components are standardized for through-hole mounting and are intended for general-purpose EMI suppression in consumer and industrial electronics.

Common Mode Chokes Replacement Considerations

Direct substitutes include other ECMT1V1717S variants with identical mechanical dimensions but different electrical characteristics, such as ECMT1V1717S-1R0-R (1 mH) or ECMT1V1717S-2R0-R (2 mH). Cross-brand replacements require matching inductance, current rating, and package type.
