Overview
The Bourns SRF0504-191Y is a surface-mount common mode choke from the SRF0504 series, designed for EMI suppression in high-speed data lines. It features an inductance of 600 nH at 100 kHz and provides an impedance of 190 Ohms at 100 MHz. The component supports a maximum DC current of 5 A with a low DC resistance of 20 mOhms. Operating within a temperature range of -40°C to +125°C, it utilizes a ferrite core and is housed in a compact 0504 (1210 metric) package measuring 5 mm x 4.8 mm x 4.8 mm.
Feature Summary
- High current handling capability up to 5 A for robust power line filtering
- Effective EMI suppression across a wide frequency range extending to 1200 MHz
- Compact surface-mount footprint suitable for space-constrained PCB layouts
Applications
- EMI suppression in high-speed digital circuits
- Filtering noise on USB and other high-speed data interfaces
- Signal integrity protection in portable electronic devices
Procurement Notes
Verify the specific part number suffix against official Bourns documentation to ensure correct impedance and tolerance specifications. Confirm that the required operating temperature range and current ratings align with your system design constraints before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring effective common mode noise reduction without significant signal attenuation. The low DC resistance minimizes power loss, while the high current rating ensures stability under load. Ensure the physical dimensions fit the designated PCB land pattern.
Part Context
This component belongs to the Bourns SRF0504 series of shielded common mode chokes. The series offers various inductance values to suit different frequency requirements. These components are engineered for reliability in consumer electronics and industrial applications where electromagnetic interference must be strictly controlled.
Replacement Considerations
Consult official Bourns substitution guides for verified alternatives within the SRF0504 family or equivalent series from other manufacturers. Ensure any substitute matches the critical parameters of inductance, impedance, and physical package dimensions.
