ceramic trimmer capacitors, chip SMD 3mm trimmer ceramic capacitors

¡¡

Ceramic Trimmer Capacitors 3mm SMD Type

¡¡

Featrure:

Very compact package type. For reflow soldering use.

Preserved from solvent. Dust-Proof structure.

Low capacitance drift. Optimum for automatic chip mounter due to

their small allowance in the dimensions and no air leakage.

Maximum capacitance can be checked by triangle-cut of rotor.

Operating temperature range: -25¡æ

∼+85¡æ

Rated working voltage: 3pF to 6pF: 50V DC

10pF to 30pF: 110V DC

Dielectric withstanding voltage: 3pF to 6pF: 110V DC

10pF to 30pF: 220V DC

Insulation resistance: 10•M¦¸min. Rotation torque: 10~70g.cm
