reel; 2010 : 3000pcs; 2512 : 1800pcs.
Reels of 1000pcs are available on request.
Application Notes
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
