SPECIFICATIONS
Operating Temperature Range: –35°C to +85°C
Maximum Capacitance: When set at the tight
position (tight defined as 28 oz-in/2.0 kg-cm), the
maximum capacitance will be no less than the
value indicated in the table.
Minimum Capacitance: When adjusting screw is
rotated 3 turns from tight position (2 turns for types
1, 5, and 9), the minimum capacitance will be no
greater than the value indicated in the table.

Insulation Resistance: 100,000 megohms min at 25°C
Capacitance change with temperature (capacitor
set at ¹/4 to ¹/2 turn from the tight position):
Types 1, 5, 9
= ± (2.5% + 0.3 pF)
Types 2, 3, 4, 6, 7, 8 = ± (1.5% + 0.3 pF)
Capacitance drift with temperature (capacitor set
at ¹/4 to ¹/2 turn from the tight position):
Types 1, 5, 9
= ± (2.0% + 0.5 pF)
Types 2, 3, 4, 6, 7, 8 = ± (1.5% + 0.5 pF)

Q: Minimum Q at 1 MHz per graph (for units which
have nominal maximum capacitance ≤ 1000 pF).
Dissipation Factor: Maximum DF = 0.004 at 1 kHz
(for units which have nominal maximum
capacitance > 1000 pF).
