Sprague Goodman's SURFTRIM® small, thin surface mount trimmers measure only 3.2 x 2.5 mm (0.125" x 0.098") with a height of less than 1.3 mm (0.051") above the mounting surface. A thin silicone coating for protection allows usage for assembly processes that include washing.
Four capacitance ranges are offered: 3.0 to 5pF, 3.0 to 10pF, 5.0 to 20pF. and 7.0 to 30pF. Q is 150 minimum at 1MHz. Temperature coefficient of capacitance is NPO ±500 ppm/°C for the two lower ranges and N750 ± 500 for the two higher ranges. Operating temperature range is -40°C to +85°C. Voltage rating is 25VDC, and dielectric withstanding voltage is 75VDC. Insulation resistance is 104MΩ minimum. Tuning torque is 10 to 150g-cm (0.14 - 2.08oz in).
