Overview
The Würth Elektronik 782853162 is a surface-mount ferrite bead designed for electromagnetic interference suppression in power lines. It features an impedance of 1500 Ohms at 100 MHz and supports a maximum current of 1 A with a DC resistance of 300 mOhms. Housed in an 0805 (2012 metric) package, the component measures 2.0 mm in length, 1.25 mm in width, and 0.9 mm in height. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- Provides effective high-frequency noise attenuation for power line applications
- AEC-Q200 qualified for automotive reliability standards
- Compact 0805 surface-mount footprint for space-constrained designs
Applications
- Automotive electronic systems requiring EMI suppression
- Power supply input filtering
- High-speed digital circuit noise reduction
Procurement Notes
Verify the specific datasheet version to confirm impedance tolerance and current ratings match design requirements. Ensure the 0805 package dimensions align with PCB land pattern specifications. Confirm AEC-Q200 compliance if the application mandates automotive-grade components. Check for moisture sensitivity levels prior to soldering processes.
Selection Notes
Select this component when a low-profile ferrite bead is needed for power line filtering in compact assemblies. The 1500 Ohm impedance at 100 MHz targets common high-frequency noise sources. Consider the 1 A current rating to ensure adequate headroom for the target circuit load without saturation or excessive heating.
Part Context
This ferrite bead belongs to Würth Elektronik's passive component portfolio, specifically targeting EMI/RFI suppression. It complements their capacitor and inductor ranges by providing targeted noise filtration solutions for sensitive electronics.
Replacement Considerations
Direct substitutes must match the 0805 package, 1500 Ohm impedance at 100 MHz, and 1 A current rating. Verify equivalent thermal performance and AEC-Q200 qualification if used in automotive contexts.
