SRF2012-361YA

Overview

The SRF2012-361YA is a two-line common mode choke from the Bourns SRF2012A series, designed for surface mount applications. It features an impedance of 360 Ohms at 100 MHz and supports a maximum DC current of 300 mA. The device has a low DC resistance (DCR) of 500 mOhm with a tolerance of ±25%. Constructed with a ferrite core, it operates within a temperature range of -55°C to +125°C. The component measures 2.0 mm in length, 1.2 mm in width, and 1.2 mm in height, utilizing four terminals for connection.

Feature Summary

• Provides common mode noise suppression for dual-line circuits
• Utilizes ferrite core material for effective high-frequency filtering
• Designed for compact surface mount integration

Applications

• Data line protection in portable electronics
• Signal integrity enhancement in communication interfaces
• Noise filtering in consumer device circuitry

Procurement Notes

Verify the specific suffix YA against official Bourns documentation to confirm exact impedance and current ratings. Ensure compatibility with RoHS standards if required by your manufacturing process. Cross-reference the package dimensions and terminal configuration with your PCB layout specifications before finalizing procurement decisions.

Selection Notes

Select this component when space-constrained designs require effective common mode noise reduction on data lines. The 300 mA rating suits low-power signal applications rather than high-current power delivery. Consider the 360 Ohm impedance profile at 100 MHz to ensure adequate attenuation for the target noise frequencies without impacting signal integrity.

Part Context

This part belongs to the SRF2012A series of multilayer chip inductors manufactured by Bourns Electronic Solutions. The series focuses on providing compact filtering solutions for modern electronic devices where board real estate is limited. These components are engineered to meet standard industrial temperature ranges and reliability requirements for general-purpose electronics.

Replacement Considerations

Consult official Bourns substitution guides or distributor cross-reference tools for verified equivalents. Ensure any substitute matches the 2012 package size, 360 Ohm impedance, and 300 mA current handling capabilities to maintain circuit performance.
