Compliant to RoHS directive 2002/95/EC
Z203 resistors are not restricted to standard values or
minimum order quantity, and can be supplied from 1 unit
with as-required values (e.g. 9.997 k vs. 10 k) at no
extra cost or delivery time.
Our application engineering department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please

Note
(1)
The leads on the Z203 connect to the Bulk Metal

Foil resistive
element at the top of the package using solder-free, all welded
construction. This high-reliability enhancement protects the
terminations from initial board-assembly and subsequent board
flexation stresses. The welded construction completely eliminates
the possibility of latent failures due to solder reflow and
solder-starved internal connections.
