Cautions

Adjustment

Maximum pressure of screwdriver should be less than 100g.f.
Use recommended screwdriver (VESSEL 9000, or equivalent tip).
High pressure can lead to extensive setting drift or damage to internal elements.

Soldering

Please refer to the recommended solder profile [Figure-2]. Unsuitable soldering conditions may cause the trimmer capacitor to deviate from specified performance characteristics.
Use proper amount of solder; excessive amounts can cause bridging between terminals or contact failure due to flux invasion. Insufficient solder may lead to insufficient soldering strength on the PCB.
Do not touch the trimmer capacitor body or terminals directly with a soldering iron, as this can cause serious damage.
Do not use flow-soldering (dipping soldering) as it might penetrate into the trimmer capacitor.
Do not use inappropriate adhesives, such as bond or instant glue.
If SEHWA's recommended land pattern is not used, check mounting alignment in your mass production line.
After reflow soldering, cool down at room temperature for at least 4 hours. Insufficient cooling time can lead to larger capacitance drift due to expansion and shrinkage.

Storage

It is recommended to use within 6 months after delivery.
Store components under temperatures of -10~40 and humidity of 30~70% RH.
Do not store the trimmer capacitor in corrosive conditions.
Do not open the package until just prior to use.
Do not store under direct sunlight or in dewy environments.

Others

Before using trimmer capacitors, please test and make a prototype product after assembly.
Do not warp and/or bend PCB to prevent trimmer capacitor from breakage.
Do not use locking paint or any substance to secure the rotor position, as this can degrade characteristics.
