Outline
:
|
| Multi-aperture
cores are used in Balun(balance-unbalance) transformers
and find wide application as broadband tranformers in
communication and CATV circuits .Multi-Holes are used
for small HF transformers, for voltage or impedance matching
in TV, communications, data transmission, instrumentation
and similar applications. They are available with 2 and
6 holes, in round and rectangular shapes . |
|
| |
|
|
Features
: |
|
Wide range of shapes, several grades, for HF matching
and suppression. High saturation flux density and low
losses at the normal working conditions. (100~500khz at
80~120° C). The slots in the rods decreases the eddy
current losses and have an additional cooling effect . |
|
| |
|
|
Applications
: |
|
Impedance coils for industrial HF welding equipment ,
TV communitcations, Data tuansmission , Power line filter
. |
