tempco of capacitors

[Grant Richter]

These are typical values, different manufacturers have different exact
specs.

Ceramic COG  0 ppm +/- 30 ppm
polystyrene -120 ppm +/- 50 ppm
polycarbonate +150 ppm +/- 50 ppm

The +/- is to indicate that the ppm varies from unit to unit.
A polycarbonate may have a tempco of +100 ppm to +200 ppm.
The polystyrene are interesting because the -120 nearly cancels
the typical +100 ppm of metal oxide resistors (for a simple RC network).
