Overview
The Schaffner RT8122-8-8M0 is a horizontal two-wire common mode choke designed for PCB mounting. It features an inductance of 8 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 8 A and has a typical maximum DC resistance of 21 mOhms. It operates within a temperature range of -40°C to +100°C. The device utilizes a ferrite core and is unshielded, tested at 100 kHz.
Feature Summary
- Horizontal two-wire configuration for through-hole PCB integration
- Current compensated design utilizing ferrite core material
- Unshielded construction suitable for standard electromagnetic interference suppression
Applications
- Switch Mode Power Supplies
- UPS Systems
- Electronic Devices
- Converters
Procurement Notes
Verify the specific suffix '8M0' against official TE Connectivity or Schaffner documentation to confirm the exact inductance value and tolerance band. Ensure the horizontal mounting orientation matches the target PCB layout constraints. Confirm that the 8 A current rating aligns with the application's peak load requirements without exceeding the thermal limits defined in the datasheet.
Selection Notes
Select this component when a horizontal form factor is required for space-constrained PCB designs. The 8 mH inductance provides effective noise attenuation for mid-range power applications. Consider the -30% to +50% tolerance if precise impedance matching is not critical. Verify that the unshielded nature does not interfere with nearby sensitive components or fail specific radiated emission standards.
Part Context
This part belongs to the RT-Series of common mode chokes from TE Connectivity / Schaffner. The series offers various current ratings and inductance values for different power levels. The RT8122 variant specifically denotes a horizontal mounting style, distinguishing it from vertical counterparts like the RT8522 series.
FAQ
