BCcomponents DATA SHEET 2222 808 ..... ∅10 mm Film dielectric trimmers Preliminary specification Supersedes data of 27th March 1998 File under BCcomponents, BC04 2000 Nov 02 BCcomponents Preliminary specification 2222 808 ..... ∅10 mm Film dielectric trimmers FEATURES QUICK REFERENCE DATA • Housing diameter 10 mm • For a basic grid of 2.54 mm (0.1") or 2.50 mm • Top and bottom or top adjustment • Vertical and horizontal versions • Round or hexagonal head. DESCRIPTION Cmin/Cmax VALUE 2.5/15 to 7/105 pF Rated voltage (DC) 150 V Test voltage (DC) for 1 minute 300 V Maximum contact resistance 10 mΩ Minimum insulation resistance 10000 MΩ Category temperature range: APPLICATIONS PP −40 to +70 °C • For consumer and industrial equipment. PC, PTFE −40 to +85 °C Climatic category (IEC 60068): PP DESCRIPTION The vanes of the trimmer are stacked on a sturdy plastic base. The colour of the base indicates the maximum capacitance (see Table 2). The dielectric is a film of polypropylene (PP), polycarbonate (PC) or polytetrafluorethylene (PTFE), which supports the vanes in such a way that good stability is ensured and no microphony can occur. Flux absorption between the vanes is prevented. Cleaning with solvents is not advised. Versions are available with either a vertical spindle (see Figs 1 and 2), or a horizontal spindle (see Fig.3). Both versions have top adjustment by means of a screwdriver or trimming key and bottom adjustment by means of a key as shown in Fig.7. 40/070/21 PC, PTFE 40/085/21 Minimum storage temperature −55 °C Related specification IEC 60418-1 and 4 MECHANICAL DATA DESCRIPTION Effective angle of rotation Operating torque 2 to 25 mNm Maximum axial thrust 2N QUALITY LEVEL Sampling and data evaluation for quality level in accordance with “MIL-STD-105D” and “IEC 60410”: <0.15% major defects <0.65% minor defects. Each capacitor is tested for minimum Cmax and is also subjected to the full test voltage.
