TYPICAL PERFORMANCE
The WOMC series features a standard 16 and 20 pin wide
body (0.30") small outline surface mount style that can
accommodate resistor networks to your particular
application requirements. The networks can be constructed
with Passivated Nichrome, or Tantalum Nitride resistor films
to optimize performance.

ORDERING INFORMATION CHECK LIST (CUSTOMS)
Special requirements should be identified in advance, but as a minimum, you should have the following information ready.
ELECTRICAL
1. Resistors, by value and tolerance
2. Reference resistor(s) and matching of which resistors to which
reference resistors
3. Reference by ratio
4. Absolute temperature coefficient of resistivity
5. Temperature tracking of subordinate resistors to reference
resistor(s)
6. Maximum operating voltage
7. Resistor power ratings
8. Operating temperature range
Lead (Pb)-free example:
WOMCTXXXXA
MECHANICAL
1. Maximum allowable seated height (from PC board to top of
network)
2. Special marking concerns
3. Schematic pin out of package
