The document is a TUSONIX handbook and catalog for disc ceramic capacitors. It includes an index, applications and features, physical characteristics, specials, and capacitance charts for 3 kV and 4 kV discs. It also gives ordering instructions: specify TUSONIX style number, voltage, TC code, capacitance, tolerance, and any special instructions.
The latter pages cover aging of hi-dielectric constant barium titanate based ceramics, EIA code temperature ranges and maximum capacitance change, temperature coefficients, and capacitance tolerance tables. Notes in the document cover derating to 67% of rated voltage for +125°C operation, lead wire gauges, conformal coating, and marking.
| Voltage derating for +125°C operation | 67% of rated voltage |
|---|---|
| Lead wire gauge availability up to 2 kV | 20, 22, and 24 AWG |
| Body insulation | Conformal coating |
| Marking | Trademark, capacitance, tolerance, temperature coefficient, and voltage |
Specify the TUSONIX style number, voltage, TC code, capacitance, tolerance, and any special instructions.
The document states derating to 67% of rated voltage for +125°C operation.
They have a predictable capacitance aging effect, which is a loss of capacitance with time.
Values up to and including 2 kV are available with 20, 22, and 24 AWG leads.
