Overview
The C20530A-902 is a two-line common mode choke manufactured by ITG Electronics, Inc., designed for through-hole mounting. It features an inductance of 9 mH measured at 10 kHz and supports a maximum current rating of 14.5 A. The component exhibits a direct current resistance (DCR) of 7.8 mOhm. This toroidal inductor is engineered for switch-mode power supply applications, offering low core loss and compact design characteristics suitable for high-power environments.
Feature Summary
- Two-line configuration for effective common mode noise suppression
- Through-hole DIP package construction for robust PCB integration
- High current handling capability with low DC resistance
- Toroidal core design minimizing distributed capacitance
Applications
- Switch-mode power supplies
- EMI filtering in electronic circuits
- Power line noise suppression
Procurement Notes
Verify the specific suffix and tolerance requirements against the official ITG Electronics datasheet before ordering. Confirm that the through-hole pin spacing matches your PCB layout constraints. Ensure the 14.5A current rating meets your system's peak load demands to prevent saturation. Cross-reference the 9 mH inductance value at 10 kHz with your filter design specifications.
Selection Notes
Select this component when a high-current, low-resistance common mode choke is required for through-hole assembly. The 9 mH inductance provides significant attenuation for common mode signals while maintaining efficiency under heavy loads. Consider the physical size and thermal performance relative to adjacent components on the board.
Part Context
This part belongs to the C20530A series of DIP common mode chokes from ITG Electronics. The series offers various inductance values tailored for different power levels. The C20530A-902 specifically targets applications requiring higher current capacity compared to lower-rated variants in the same family.
Replacement Considerations
Direct substitutes may include other 9 mH, 14.5A two-line through-hole chokes from manufacturers like Panasonic or KEMET, provided pin compatibility and electrical parameters match exactly.
