I was recently asked to find a cross for a surface mount ferrite bead from Nic Components Corp. with the following specifications:
| Specification Name | Value |
|---|---|
| Impedance @ Frequency | 39 Ohms @ 100MHz |
| DC Resistance | 0.03 Ohms |
| DC Current Max | 4A |
| Package Case Size | 0805 |
I recommend DigiKey part number MH2029-400YCT-ND; Manfuacturer part number MH2029-400Y based on the values above, it should be a decent cross with minor changes compared to the original.
Please review the datasheets to ensure the alternative will work for your application.
