The TCR is obtained by the process capability and

does not rely on a selection process. It does not vary

from lot to lot nor by ohmic value.

MODEL NO. RESISTANCE VALUE

TOLERANCE

Resistance Value, in ohms, is expressed by a series of 6 characters,

5 of which represent significant digits while the 6th is a dual purpose

letter that designates both the multiplier and the location of the comma

or decimal point.

The Z201 (0.150 lead spacing) and Z201L (0.200 lead spacing)

Bulk Metal

This is the 3rd in a series of ultra-precision resistors since the

first Bulk Metal

Each represents an improvement on the earlier model. The

TCR slope of the Z201 is 0.2ppm/

°C (MIL range) and is an

order of magnitude better than the original S102C. The Bulk
