CAF-0.4-47

Overview

The Talema Group LLC CAF-0.4-47 is a two-line common mode choke designed for through-hole mounting. It features an inductance of 47 mH measured at 10 kHz and supports a current rating of 400 mA. The component has a DC resistance (DCR) of 1.942 Ohms and operates with a voltage rating of 250 VAC. This toroidal choke is engineered to suppress electromagnetic interference in dual-line circuits.

Feature Summary

Provides common mode noise suppression for two-line configurations
Utilizes a toroidal core structure for efficient magnetic coupling
Designed for through-hole PCB integration

Applications

Power supply input filtering
Data line noise reduction
Electromagnetic interference suppression in electronic devices

Procurement Notes

Verify the exact part number CAF-0.4-47 against manufacturer documentation to ensure compatibility with specific circuit requirements. Confirm that the 400 mA current rating and 47 mH inductance meet design specifications. Check for RoHS compliance status if required by regulatory standards. Ensure through-hole mounting capabilities align with the target printed circuit board layout.

Selection Notes

Select this component when a 47 mH inductance value is required for common mode noise attenuation in low-current applications. The 400 mA rating suits circuits with modest power demands. Verify that the 1.942 Ohm DC resistance does not introduce excessive voltage drop. Ensure the physical dimensions accommodate the available board space for through-hole assembly.

Part Context

This component belongs to the Talema Group LLC common mode choke family, specifically the CAF series. These chokes are characterized by their toroidal construction and through-hole termination style. The series offers various inductance values tailored for different noise suppression needs across multiple electronic applications.

Replacement Considerations

Consult official datasheets for direct substitutes from Talema or other manufacturers offering equivalent 47 mH, 400 mA common mode chokes. Verify pinout compatibility and physical footprint before substitution.
