Packaging
0805 and 1206 PWC series resistors are
supplied on 8mm carrier tape and 7 inch
reels as per IEC 286-3, quantity per
reel; 3000.
2010 and 2512 PWC series resistors are
supplied on 12mm carrier tape and 7
inch reels as per IEC 286-3, quantity per
reel; 2010 : 3000pcs; 2512 : 1800pcs.
Reels of 1000pcs are available on
request.
PWC resistors are ideally suited for handling by automatic
methods due to their rectangular shape and the small
dimensional tolerances. Electrical connection to a ceramic
substrate or to a printed circuit board can be made by reflow
or wave soldering of wrap-around terminations.
Wrap-around terminations provide good leach properties and
ensure reliable contact. Due to the robust construction, the
PWC can be immersed in the solder bath for 30 seconds at
260°C. This enables the resistor to be mounted on one side
of a printed circuit board and wire-leaded components
applied on the other side.
PWC resistors themselves can operate at a maximum
temperature of 155°C. For soldered resistors, the joint
temperature should not exceed 110°C. This condition is met
when the stated power levels at 70°C and recommended pad
and trace areas are used. Allowance should be made if
smaller areas of copper are used.
A full Application Note on the PWC Series is available.
