Overview
The SRF2012-301Y is a two-line common mode choke from the Bourns SRF2012A series, designed for surface mount applications. It features an iron core and offers an impedance of 300 Ohms at 100 MHz. The component supports a maximum DC current of 290 mA with a typical DC resistance of 400 mOhm. It operates within a temperature range of -55°C to 125°C and utilizes a four-terminal surface mount package.
Feature Summary
- Provides common mode noise suppression via dual-line configuration
- Utilizes iron core material for effective high-frequency filtering
- Designed for compact surface mount integration
Applications
- Signal line noise filtering in electronic circuits
- EMI suppression for data transmission interfaces
- Common mode interference reduction in consumer electronics
Procurement Notes
Verify the specific suffix designation (Y vs YA) against the manufacturer's official documentation to ensure accurate part identification. Confirm that the required impedance characteristics and current ratings align with the circuit design specifications before procurement. Ensure compliance with relevant environmental standards such as RoHS if applicable to the target application.
Selection Notes
Select this component when a low-profile surface mount solution is required for common mode noise attenuation. Consider the 290 mA current rating and 400 mOhm DC resistance to ensure compatibility with the signal line requirements. Evaluate the 300 Ohm impedance at 100 MHz against the specific frequency spectrum of the noise to be suppressed.
Part Context
This component belongs to the SRF2012A series of multilayer chip inductors manufactured by Bourns Inc. The series is characterized by its small footprint and suitability for automated surface mount assembly processes. These inductors are engineered to provide reliable performance in space-constrained electronic designs requiring effective electromagnetic interference management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult the manufacturer's official documentation or authorized distributors for verified equivalent components that meet the same electrical and mechanical specifications.
