Overview
The Schaffner RN102-0.3-02-22M is a common mode filter choke designed for through-hole PCB mounting. It features an inductance of 22 mH with a tolerance range of -30% to +50%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 1.3 ohms. It operates within a temperature range of -40°C to +100°C. The physical dimensions are 14.00 mm x 14.00 mm with a maximum height of 9.30 mm, utilizing a horizontal configuration with four pins.
Feature Summary
- Provides common mode noise suppression for differential signal lines
- Designed for vertical or horizontal printed circuit board integration
- Constructed for reliable operation across extended industrial temperature ranges
Applications
- Medical device power input filtering
- Industrial control system signal conditioning
- Consumer electronics EMI suppression
Procurement Notes
Verify the specific orientation suffix (e.g., M for horizontal) against the design footprint, as Schaffner RN series components vary by pin configuration. Confirm RoHS compliance status for the specific manufacturing batch if required by regulatory standards. Ensure the selected variant matches the mechanical constraints of the assembly process.
Selection Notes
Select this component when a 22 mH common mode inductance is required for low-current applications up to 300 mA. The 1.3 ohm DC resistance must be evaluated against voltage drop requirements in the circuit. Verify that the 14.00 mm square footprint fits the available PCB real estate and that the 9.30 mm height clearance is sufficient for surrounding components.
Part Context
This part belongs to the Schaffner RN series of EMC/EMI components, which are widely used in medical and industrial equipment. The series offers various inductance values and current ratings tailored for different noise suppression needs. These chokes are engineered to meet stringent safety and performance standards for sensitive electronic environments.
Replacement Considerations
RN202-0.3-02-22M is a vertical variant with identical electrical specifications but different mechanical orientation. RN102-0.3-02 is a related model with 12 mH inductance. Verify mechanical compatibility before substitution.
