Figure 1
CONSTRUCTION
The chips have a high alumina substrate (96% minimum)
with a ruthenium oxide resistance element and silver
palladium, nickel and solder plated terminations. A glazed
protection coat is applied to the resistive element (See
Fig. 1)
TERMINATIONS
Solderability
The terminations meet the requirements
of IEC 115-1, Clause 4.17.3.2.
The terminations meet requirements of
IEC 68.2.21.
Strength
MARKING
All resistors are individually marked with 3 digits. The
first two digits are the significant figures and the third
defines the number of added zeros. Jumpers are marked
000. Type 0402 have no marking.
E96 1% components that can not be marked with 4 digits
will be marked with a standard 3 digit code. Details can
be supplied upon request.
SOLVENT RESISTANCE
The protective epoxy lacquer and marking are resistant to
all normal industrial cleaning fluids suitable for printed
circuits.
PACKAGING
All chips are tape mounted and supplied on standard 8mm
tape reel, as IEC publication 286-3.
180mm (7 inch) reel carries 5,000 pieces. (Except 0402
carries 10,000 pieces)
250mm (10 inch) reel carrying 10,000 pieces can be supplied
by agreement.
Chips are taped element side up as standard.
If chips are to be taped face down please specify.
Type 2010 – 4,000 pcs
Type 2512 – 4,000 pcs
BULK CASSETTE PACK AVAILABLE
CHIP RESISTOR LAB STOCK FOR DESIGNERS
WCR chip resistors are available in a special package
containing 50 each of the E24 values. Please contact the
sales desk for full details of this excellent solution for
designers and your prototype build requirements.
