SCM20-261T-RC

Overview

The SCM20-261T-RC is a surface mount common mode choke manufactured by Allied Components International. It features two lines and provides an impedance of 260 Ohms at 100 MHz. The component has a current rating of 310 mA and a voltage withstand capability of 125 V. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• Designed for filtering EMI/RFI noise in signal lines
• Surface mount construction for automated assembly

Applications

• Signal line noise suppression
• EMI/RFI filtering applications

Procurement Notes

Verify the specific impedance value of 260 Ohms at 100 MHz against design requirements. Confirm the 310 mA current rating is sufficient for the target circuit. Ensure the operating temperature range of -40°C to +105°C meets environmental specifications. Check RoHS compliance status if required by project standards.

Selection Notes

Select this component when a 260 Ohm impedance at 100 MHz is required for common mode noise reduction. The 310 mA current rating suits low-current signal lines. The surface mount package facilitates PCB integration. Verify that the 125 V withstand voltage aligns with system electrical constraints.

Part Context

This part belongs to the SCM20 series of common mode chokes from Allied Components International. Similar models include the SCM20-121M-RC and SCM20-900T-RC, which offer different impedance values while maintaining similar form factors and mounting types for consistent board layout strategies.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternatives like the SCM20-121M-RC or SCM20-900T-RC only if their impedance characteristics (120 Ohms or 90 Ohms respectively) meet the specific noise filtering requirements of the application.
