Packaging:
Bulk in plastic bags – minimum quantity 100 pieces per value
Blistertape acc. to IEC 60286-3 – minimum 1000 pieces per value
Reel diameter 180 mm or 330 mm
Ordering Data:
Type – value – tolerance – TCR – packaging
Example: CRW 1216 100 R
±
1% TK50 Tape 180 mm
Untrimmed parts are indicated by the extension “NA” in the order code:
Type – value – tolerance – NA – TCR - packaging
Example: CRW 1216 100 R
±
5% NA TK50 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.

At continuous power dissipation the dimensions of solder-pads have to secure sufficient heat-conduction.
TC/50: Temperature range + 25°C...+ 125°C
3)
Higher power requires oversized solder pad

Continuouse operating voltage: U =
√(P*R)
Zero-Ohm-Jumper: :< 50 mOhm. TCR max. + 4000 ppm/K
M at 2512/4020: Meander structure with higher working voltage in brackets.
