TRIMMER CAPACITORS

FEATURES

• Very large capacitance ranges

• High Q

• Good RF current handling capability

• Many forms and mounting styles

SPECIFICATIONS

Operating Temperature Range: –35°C to +85°C

Capacitance change with temperature (capacitor

set at /4 to /2 turn from the tight position):

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.

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 /4 to /2 turn from the tight position):

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.

Types 1, 5, 9

Types 2, 3, 4, 6, 7, 8 = ± (1.5% + 0.5 pF)

= ± (2.0% + 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).
