SRF2012-361Y

Overview

The Bourns SRF2012-361Y is a two-line common mode choke designed for surface mount applications. It features an iron core and offers an impedance of 360 Ohms at 100 MHz. The component supports a maximum DC current of 280 mA to 300 mA, with a maximum DC resistance ranging from 450 mOhms to 500 mOhms. It operates within a temperature range of -55°C to 125°C and utilizes a 4-pin horizontal package.

Feature Summary

• Provides effective common mode noise suppression for signal lines
• Constructed with an iron core for stable inductive performance
• Designed for compact surface mount integration

Applications

• Signal line filtering in electronic circuits
• Noise suppression in data transmission interfaces
• Common mode interference reduction in portable devices

Procurement Notes

Verify the specific suffix (e.g., YA) against official Bourns documentation to confirm exact electrical tolerances and packaging details. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the maximum DC current rating carefully, as sources may vary between 280 mA and 300 mA. Confirm the package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require a low-profile common mode choke. The 2012 metric footprint suits dense layouts. Evaluate the 360 Ohm impedance at 100 MHz against target noise frequencies. Consider the thermal operating range up to 125°C for environments with elevated temperatures. Compare DCR values to ensure voltage drop limits are met in the specific circuit application.
