Overview
The Schaffner RN152-2-02-18M is a through-hole common mode choke designed for power line filtering. It features an inductance of 18 mH at 10 kHz with a tolerance range of -30% to +50%. The component supports a maximum DC current of 2 A and has a typical maximum DC resistance of 350 mOhms. It operates within a temperature range of -40°C to +100°C. The physical dimensions are approximately 43.00 mm x 41.80 mm x 25.30 mm, utilizing a horizontal package with four pins.
Feature Summary
- Provides effective common mode noise suppression for power lines
- Utilizes ferrite core material for high inductance stability
- Designed for robust through-hole PCB mounting
Applications
- Power supply input filtering
- Industrial equipment EMI reduction
- Consumer electronics noise suppression
Procurement Notes
Verify the specific datasheet version for exact tolerance limits and thermal derating curves. Confirm pin configuration matches the target PCB footprint. Ensure the operating environment stays within the specified -40°C to +100°C range. Check for RoHS compliance documentation if required by regional regulations. Validate that the 2A current rating meets the circuit's peak load requirements.
Selection Notes
Select this component when a 18 mH inductance is required for low-frequency noise attenuation. The 2A current rating suits moderate power applications. Compare against the RN122 series for lower current needs or the RN212 series for higher current capacity. Consider the horizontal form factor for space-constrained vertical layouts. Verify compatibility with standard reflow or wave soldering processes.
Part Context
This part belongs to the Schaffner RN series of common mode chokes. It is manufactured by TE Connectivity / Schaffner. The series is known for providing EMC solutions for various electronic devices. The RN152 variant specifically targets applications requiring 2A current handling capability.
Replacement Considerations
RN122-1-02-18M offers similar inductance but lower current rating (1A). RN212-2-02-18M provides comparable performance with potentially different impedance characteristics. Verify pinout and mechanical dimensions before substitution.
