n Features
Because this MCF has a built-in transformer, it is possible to match an input/output
circuit with various impedance values.
l Stable temperature characteristics.
l This product can be manufactured according to your requested terminating
impedance value.
l Because it has already been completely adjusted, no adjustment is needed before
use.
l It can be manufactured with a wide frequency band.
Caution
Because it has a non-enclosed structure, it cannot be washed.
