Cautions:
- Adjustment: Maximum pressure of screwdriver should be less than 100g.f. Use recommended screwdriver. High pressure can lead to setting drift or damage.
- Soldering: Use proper amount of solder. Avoid flux invasion. Do not touch capacitor body/terminal with soldering iron. Do not use flow-soldering. Recommended solder profile should be followed. Cool down at room temperature for at least 4 hrs after reflow soldering.
- Storage: Recommended to use within 6 months. Store under -10~40 and 30~70% RH. Avoid corrosive conditions, direct sunlight, or dewy environments. Do not open package until prior to use.
- Others: Do not warp/bend PCB. Do not use locking paint. Test and make prototype before assembly.
