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)

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)
