140NEX
CHASSIS MOUNT – SHIELDED
IMPEDANCE MATCHING TRANSFORMER
This transformer operates in the 20 Hz to 20 KHz range.
The metal can provides excellent shielding from a broad
range of external sources. The nickel core provides high
permeability combined with low losses.
Typical applications Input/output Isolation, Line Matching,
Driver, Hybrid applications.
