RN112-0.4-02

Overview

The Schaffner RN112-0.4-02 is a current-compensated common mode choke designed for power line filtering applications. It features a horizontal board mount configuration with PCB terminals, supporting two lines. The component operates at a maximum voltage of 300 VDC and handles a current rating of 0.4 A. It is constructed with a ferrite core material and offers an inductance of 39 mH at 10 kHz. The device complies with UL 94V-0 standards and is rated for PD2 pollution degree with an IP00 protection level.

Feature Summary

• Current-compensated design for effective common mode noise suppression
• Horizontal board mount configuration for space-efficient integration
• Dual-line support capability for balanced power line filtering

Applications

• Power supply input filtering
• Electronic equipment EMC compliance
• Industrial control systems noise reduction

Procurement Notes

Verify the specific inductance value required for your application, as the base model number may correspond to different variants such as the RN112-0.4-02-39M which specifies 39 mH. Confirm that the 0.4 A current rating meets your circuit requirements. Ensure the horizontal mounting style aligns with your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a compact, dual-line common mode choke is needed for low-current DC applications. The 300 VDC rating suits low-voltage power circuits. Consider the horizontal form factor for boards where vertical height is limited. Verify that the ferrite core characteristics match your frequency range needs, specifically around 10 kHz for the 39 mH variant.

Part Context

This part belongs to the Schaffner RN-Series, a family of EMC chokes designed for power line filtering. The series provides cost-effective solutions for general-purpose electromagnetic interference suppression. These components are widely used in electronic devices requiring robust noise filtering within small form factors.

Replacement Considerations

The RN112-0.4-02-39M is a confirmed variant with specified 39 mH inductance. Other models in the RN112 series offer different current ratings or inductance values. Ensure any substitute matches the 0.4 A current handling and 300 VDC voltage rating to maintain circuit safety and performance.
