Ceramic capacitors, constructed from ceramic materials, are also known as ceramic dielectric capacitors. Depending on the specific ceramic material used, they can be broadly classified into two categories: low-frequency ceramic capacitors and high-frequency ceramic capacitors. When classified by structural form, they can be further categorized into disc-type, tubular, rectangular, chip-type, feed-through, and other varieties.


①. Repeated voltage withstand tests conducted by users may damage the capacitor; therefore, any capacitor subjected to such testing must not be subsequently used as a qualified product.

②. When mounting capacitors onto a PCB, it is essential that the capacitor's leads align perfectly with the corresponding solder pads on the PCB. Failure to do so may result in poor solder joints between the capacitor and the PCB, lead deformation, or physical damage to the capacitor body.

③. Avoid subjecting the capacitor to any form of squeezing, bending, or external mechanical impact.

④. If resin molding is to be applied over the capacitor, please consult with our relevant technical personnel in advance.

⑤. Once a capacitor has been soldered onto a PCB, do not attempt to forcibly move it or apply force to tilt its body.

⑥. Do not use a capacitor that has been soldered to a PCB as a handle to lift or carry the board; doing so may compromise the solder joints or damage the capacitor's encapsulation layer.
