Overview
The Würth Elektronik 782632121 is a WE-CBA series surface-mount ferrite bead designed for EMI suppression in signal lines. It features a 0603 (1608 metric) package with dimensions of 1.60mm x 0.80mm and a maximum height of 1.00mm. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 500 mA. Its maximum DC resistance (DCR) is 200 milliohms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- High noise suppression capability in a compact 0603 footprint
- Low DC resistance for minimal signal loss in power or data lines
Applications
- Automotive electronic systems requiring EMI filtering
- Signal line noise suppression in consumer electronics
- Portable device power distribution networks
Procurement Notes
Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling but not electrical performance. Confirm RoHS compliance status and country of origin details during procurement. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design.
Selection Notes
Select this component when a low-profile 0603 ferrite bead is needed for high-current signal paths up to 500 mA. The 120 Ohm impedance at 100 MHz makes it suitable for broadband noise attenuation. Consider the 200 milliohm DCR for voltage drop calculations in sensitive circuits. The AEC-Q200 rating ensures suitability for harsh automotive environments.
Part Context
This part belongs to the WE-CBA series from Würth Elektronik, which specializes in surface-mount ferrite beads for EMI suppression. The series offers various impedance values and current ratings in standard metric packages. The 782632121 specifically targets applications requiring robust noise filtering in space-constrained designs while maintaining high current carrying capacity.
Replacement Considerations
Check datasheets for equivalent parts offering similar 120 Ohm impedance at 100 MHz and 500 mA current rating in a 0603 package. Verify that any substitute also meets AEC-Q200 requirements if used in automotive applications. Ensure physical dimensions and terminal configurations are compatible with existing PCB footprints.
