Ivyland, Pa. Cal-Chip Electronics Inc. has expanded its CHV series of high voltage multi-layer ceramic chip (MLCC) capacitors with voltages of up to 10 kV. These devices are typically specified for surge suppression and temperature compensation in high-voltage applications where PC-board space is limited. Applications include wireless and portable products such as notebook computers, cellular phones, PDAs, camcorders, VCRs, telecommunications and test equipment.
The CHV series delivers low equivalent series resistance (ESR), excellent frequency response, and excellent mechanical strength. In addition, the devices are said to offer excellent volumetric efficiency and stability of capacitance with temperature due to their unique construction process. These devices are available in case sizes from 0603 to 8060 in COG (NPO), X7R, and Y5V/Z5U dielectrics.
These MLCC caps are offered in voltages of 250 V to 10 kV, and in capacitance values ranging from 1.0 pF to 1.2 μF. The operating temperature is -55°C to 125°C, with temperature coefficient of capacitance (TCC) ratings of ±15%/°C for X7R dielectric, 0±30 ppm/°C for COG and +22 to -56%/°C for Y5V/Z5U dielectrics.
Available on tape and reel, prices range from $0.01 to $10.00 each in production quantities, depending on specifications. Delivery is from stock to ten weeks. Click here for the CHV series datasheet.
