Overview
The Bourns Inc. 8106 is a vertical, through-hole common mode choke belonging to the 8100 series. It features four PC pins with a pitch of 20.32 x 10.16 mm and physical dimensions of 1.200 inches in length by 0.600 inches in width. The component provides an inductance of 5 mH at 1 kHz and supports a maximum current rating of 3.7 A. Its DC resistance is specified as 70 mOhm, and it operates within a temperature range of -55°C to 105°C. The unit offers a dielectric strength of 1500 Vrms.
Feature Summary
- Vertical mounting configuration with four printed circuit board pins
- High dielectric strength for electrical isolation
- Through-hole construction for robust mechanical attachment
Applications
- Power supply line filtering
- General use electromagnetic interference suppression
Procurement Notes
Verify the specific suffix (e.g., RC) when sourcing, as availability varies by distributor. Confirm that the base part number corresponds to the correct pin pitch and inductance value required for the design. Check RoHS compliance status directly on the datasheet, as some listings indicate non-compliance for certain variants. Ensure the operating temperature range meets the environmental requirements of the final assembly.
Selection Notes
Select this component for applications requiring high current handling up to 3.7 A with significant common mode noise reduction. The vertical package allows for compact PCB layouts while maintaining adequate spacing. Verify that the 5 mH inductance at 1 kHz aligns with the target frequency spectrum for noise attenuation. Consider the 1500 Vrms dielectric strength for safety isolation requirements in mains-connected circuits.
Part Context
This component is part of the Bourns 8100 series of common mode chokes. The series is designed for general-purpose filtering in power lines. The 8106 model specifically denotes the 5 mH inductance variant within this family. These components are manufactured by Bourns Electronic Solutions, a provider of electronic components for industrial and consumer markets.
Replacement Considerations
The 8106-RC is a verified equivalent part number from Bourns. When substituting, ensure the replacement maintains the same 4-pin vertical footprint and 20.32 x 10.16 mm pin pitch. Verify that the substitute part matches the 5 mH inductance and 3.7 A current rating specifications.
