April 3, 2008 8:36 am | Product Releases | CommentsSuited for telecom and microwave projects requiring miniature components, the SGC3S series ceramic trimmer capacitors measure 0.126” (3.2 mm) × 0.177” (4.50 mm) × 0.059” (1.5 mm). The capacitors are constructed with high temperature liquid-crystal polymer housings for superior durability and low dielectric loss to resist penetration by dust and flux, and are colored to make each of the five available capacitance ranges easily identifiable. Requiring minimal capacitance drift over the operating temperature range of -25°C to 85° C, the SGC3S series capacitance ranges are: SGC3S030 (Black): 1.2 pF to 3.0 pF; SGC3S060 (Blue): 2.2 pF to 6.0 pF; SGC3S100 (Ivory): 3.0 pF to 10.0 pF; SGC3S200 (Pink): 5.5 pF to 20.0 pF; SGC3S300 (Green): 8.0 pF to 30.0 pF. Designed for reflow soldering and available in embossed carriers, 1,000 pieces per 7 in (18 cm) reels, the capacitors are well-suited for placement on boards with automated pick-and-place equipment.
