817-1846-ND Inductivity specified with 14µH

For 817-1846-ND the Inductivity is specified with 14µH, as this is written in the data sheet and the description of the part on our product page.

However, it turns out that it is marked with 2 x 14µH, as also shown on our picture, therefore it can easily be mis-understood when comparing and checking in the data sheet and on our website.

It depends on the use case – this part consist of two CMC (COMMON MODE CHOKE) and as

Application type #1:


Symmetrical/differential mode in parallel configuration the Inductance is specified with 14µH and whereas

 

Application type #2:


Symmetrical/differential mode in series configuration the Choke is specified with 56µH – even when being marked with 14µH. To calculate the inductance we will need to find AL the formula is (AL = H x turns²). So, “14µH x 2² = 56µH
