Material description:
CH dielectric ceramic is a zero-temperature ticket dielectric material in Class I ceramics. In the temperature range of -40 to +85 degrees, the capacity change is about -+0.2%, and the loss tangent is about 0.0001; this ceramic has excellent The withstand voltage characteristic of the medium reaches 10~15kv AC withstand voltage per millimeter of thickness, and the bias voltage characteristic is very stable. From 1KV voltage to 20KV, the capacity change rate is less than 0.2%; this material of EECTECH can achieve 100 The dielectric constant of ~200 greatly expands the design space and creates infinite possibilities for the application of ceramic capacitors in narrow spaces. Especially in products such as solid sealed poles that have strict requirements for installation size, it has a greater advantage, which can easily achieve small size and large capacity
