DESCRIPTION
The KV1835K is a variable capacitance diode designed for
UHF applications.
The KV1835K is available in a very small UFD Surface
Mount Package.
Note: Rank is determined after testing and marked on the
reel. All the diodes on a reel have the same rank, but rank
can not be specified when ordering.
