Overview
The Bourns SRF2012A-361YA is a two-line common mode chip inductor from the SRF2012AA series, featuring a ferrite core and surface mount termination. It provides an impedance of 360 ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and has a rated voltage of 50 VDC. Its direct current resistance (DCR) is 500 mΩ ±25%. The physical dimensions are 2 mm in length, 1.2 mm in width, and 1.2 mm in height. It operates within a temperature range of -55°C to 125°C.
Feature Summary
- Dual-line configuration for effective common mode noise suppression
- Ferrite core construction for stable magnetic performance
- Compact surface mount footprint suitable for space-constrained designs
Applications
- Data line filtering in portable electronic devices
- Noise suppression in USB interface circuits
- Signal integrity protection in high-speed digital communication lines
Procurement Notes
Verify the specific suffix 'YA' against the manufacturer's official datasheet to confirm impedance and tolerance specifications. Ensure the ordering part number matches the required package style and reel quantity. Confirm RoHS compliance status if restricted substances are a constraint for the final assembly process.
Selection Notes
Select this component when dual-line common mode filtering is required for low-current signal paths. The 300 mA rating suits data lines rather than power delivery. Verify that the 360 ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Ensure the PCB land pattern accommodates the 2x1.2x1.2 mm body size.
Part Context
This part belongs to the Bourns SRF2012AA series of common mode chokes. The series offers various impedance values and current ratings within the same compact 2012 package. These components are designed for applications requiring efficient noise reduction in small form factor electronics without compromising signal integrity.
Replacement Considerations
Consult the official Bourns replacement guide or cross-reference tools for verified equivalents. Ensure any substitute maintains the 2012 package dimensions, 360 ohm impedance, and 300 mA current rating to preserve circuit functionality.
