Overview
The Schaffner RN112-0.5-02 is a common mode choke from the RN series, designed for power line filtering applications. It features a through-hole mounting type and horizontal orientation. The component operates within a temperature range of -40°C to +100°C. Specific variants within this base model number include inductance values such as 18 mH (RN112-0.5-02-18M) and 27 mH (RN112-0.5-02-27M), typically rated for 500 mA current with two lines.
Feature Summary
- Provides common mode noise suppression for power lines
- Supports through-hole mounting for PCB integration
- Operates reliably across extended industrial temperature ranges
Applications
- Power line filtering requiring stable inductance
- Electromagnetic interference suppression in electronic equipment
- Common mode choke applications in horizontal PCB layouts
Procurement Notes
Verify the specific suffix code (e.g., -18M, -27M) when ordering, as the base part number RN112-0.5-02 represents a family with varying inductance values. Confirm the required inductance tolerance and current rating against the application datasheet. Ensure the through-hole footprint dimensions match the target PCB design before procurement.
Selection Notes
Select the appropriate variant based on the required inductance value, such as 15 mH, 18 mH, or 27 mH, depending on the specific filtering needs. Consider the 500 mA current rating and the operating temperature range of -40°C to +100°C. Ensure the horizontal mounting style fits the mechanical constraints of the assembly.
Part Context
The RN112-0.5-02 belongs to Schaffner's RN series of common mode chokes. This series is characterized by its compact size and suitability for through-hole mounting. The components are designed to meet RoHS compliance standards, ensuring environmental safety for modern electronic manufacturing processes.
Replacement Considerations
Direct substitutes depend on the specific inductance variant required. For example, RN112-0.5-02-18M may be replaced by other 18 mH common mode chokes with similar current ratings and package dimensions. Verify electrical parameters and physical footprint compatibility before substitution.
