ENGINEERING BULLETIN SG-500D Sprague-Goodman Supercedes SG-500C MICA DIELECTRIC COMPRESSION TRIMMER CAPACITORS FEATURES Very large capacitance ranges Good RF current handling capability High Q Many forms and mounting styles SPECIFICATIONS Operating Temperature Range: 35C to +85C Capacitance change with temperature (capacitor 1 1 set at /4 to /2 turn from the tight position): Maximum Capacitance: When set at the tight Types 1, 5, 9 = (2.5% + 0.3 pF) position (tight defined as 28 oz-in/2.0 kg-cm), the Types 2, 3, 4, 6, 7, 8 = (1.5% + 0.3 pF) maximum capacitance will be no less than the value indicated in the table. Capacitance drift with temperature (capacitor set 1 1 at /4 to /2 turn from the tight position): Minimum Capacitance: When adjusting screw is Types 1, 5, 9 = (2.0% + 0.5 pF) rotated 3 turns from tight position (2 turns for types Types 2, 3, 4, 6, 7, 8 = (1.5% + 0.5 pF) 1, 5, and 9), the minimum capacitance will be no greater than the value indicated in the table.
