Hello Forum members,
Still looking for some parts for my Winterhill.
Found stock on Farnell but i'm not able to order.
28C0236-0JW-10 - Ferrite Bead, Axial Leaded, 998 ohm, 5 A, 0.01 ohm Fabrikant: LAIRD
i need 4 of these.
None stock on digikey and farnell,
MIC29300-12WT - LDO Voltage Regulator - Fixed, 26V input, 12Vnom/3 A out, TO-220-3
i need 1
Any members have these spare in the shack and willing to sell them ?
This raises a general point. You can substitute alternate compatible parts. Take a look at the schematic. If in doubt, ask.
The 12V linear regulator is there for protection. It allows for people putting in more than the 14V upper limit of the switching regulators by accident. If you are very careful, and you can guarantee not to put in more than 12V, and I mean 12V, really 12V, not 13.8V you can bypass it for testing while waiting for the part to come back in stock. That should get you up and running.
For the Laird ferrite bead you can use Digikey part no 240-2491-nd
it uses the same bead so just push one of the wires through the spare hole
For the regulator I used a sm one Digikey part no 576-2222-nd
I straightened the legs and used a small clamp arrangment to fasten both devices
to the case instead of using two bolts.
I may have some spares
