Hello,

Is there any alternative for 4322 021 33870 (BOBBIN, ETD44)?
What 's the meaning of ungapped core and gapped core?
Is it due to the internal structure?
Pls advise.
Thanks so much.

I'm sure You can find an equivalent type.What is the manufacturer?
The gap = air-gap need some application to avoid saturation of core.
If the core haven't air-gap You can make it, but if have, and for application no needed = problem...

Hello,

The manufacturer is philips semiconductor.
Btw, how do we differentiate the e-core which is ungapped?
Is the center part of the e-core shorter?
Pls advise.
Thanks so much.

As i see, this is an order-number, but i can't find anything. I have a catalog from about Ferroxcube (this is Philips product-name).
See this type-numbering maybe help.
