L = Length, B = Width, D = Thickness, C = Width of wrap around (in mm)
Packaging:
Bulk in plastic bags – minimum quantity 100 pieces per value
Embossed carrier tape acc. to IEC 60286-3 – minimum 500 pieces per value (CHS0402: 1000 pcs.)
Reel diameter 180 mm or 330 mm
Ordering Data:
Type – value – tolerance – TCR – packaging
Example: CHR 0805 221k
0,5% - TCR 100 - Tape 180 mm
Untrimmed parts are indicated by the extension “NA” in the order code:
Type – value – tolerance – NA – TCR - packaging
Example: CHR 0805 221k
10% NA TCR 100 Tape 180 mm
If no requirements for TCR and taping are given, the standard value (highest value in table) will be
supplied and packaging is bulk.

Other values of tolerance, TCR and VCR on request
Higher power rating requires an adequate heat removal (e.g. increased solder pads or Copper thicknesses). The user has to
guarantee, that solder joints will not run over their load limit. The resistor must not exceed the specified operating temperature range.
