Overview
The C301369B-352NU is a two-line common mode choke manufactured by ITG Electronics, Inc., designed for through-hole mounting. It features an inductance of 3.5 mH measured at 1 kHz and provides a common mode impedance of 9.3 kOhms at 1 MHz. The component supports a maximum current rating of 8.2A with a direct current resistance (DCR) of 23 mOhm. This fixed inductor utilizes a DIP package configuration suitable for standard PCB insertion.
Feature Summary
- Provides effective noise suppression for differential signals via common mode rejection
- Supports high current handling capabilities up to 8.2A
- Utilizes through-hole technology for secure mechanical attachment
Applications
- Power supply input filtering
- Data line noise reduction
- EMI suppression in electronic circuits
Procurement Notes
Verify the specific suffix NU against manufacturer documentation to confirm lead-free compliance and RoHS status. Ensure the through-hole footprint dimensions match the target PCB layout. Confirm that the 8.2A current rating meets the operational requirements without excessive thermal rise due to the 23 mOhm DCR.
Selection Notes
Select this component when a 3.5 mH inductance value is required for common mode noise attenuation. The 9.3 kOhm impedance at 1 MHz indicates suitability for higher frequency interference suppression compared to lower impedance variants. The 8.2A rating allows use in applications requiring significant current capacity without saturation.
Part Context
This part belongs to the C301369 series of common mode chokes from ITG Electronics. The series offers various inductance and current ratings within a standardized DIP form factor. The C301369B-352NU specifically denotes the 3.5 mH variant with 8.2A capability, distinguishing it from other series members with different electrical characteristics.
Replacement Considerations
Cross-reference with other ITG C301369 series parts if exact specifications are unavailable. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers offering similar 3.5 mH common mode chokes.
