KEMET Electrical/Physical Characteristics Product Family RF & Microwave Mulitlayer Ceramic Capacitors Series HiQ-CBR Series Case Sizes (inches/millimeters) 0201/0603, 0402/1005, 0603/1608, 0805/2012 Tolerances ± 0.05 pF, ± 0.1 pF, ± 0.25 pF, ± 0.5 pF, ± 1%, ± 2%, ± 5%, ± 10% Dielectric C0G Temperature Range -55°C to +125°C Voltage Options 6.3 V, 10 V, 25 V, 50 V, 100 V, 250 V Capacitance Values 1 pF–100 pF Features & Benefits • • • • • • • • • • Ultra-high quality factor (Q) Base metal electrode (BME) dielectric system PB-Free and RoHS Compliant No piezoelectric noise High thermal stability No capacitance change with respect to applied rated DC voltage Negligible capacitance change with respect to temperature No capacitance decay with time Non-polar device, minimizing installation concerns 100% pure matte tin-plated termination finish allowing for excellent solderability Schematic Product Checklist • Is KEMET the first source, or are other suppliers already approved? • In the latter case, who is the competitor? • What size shall the HiQ capacitor have? Usually the engineer will choose the size by power. (The 0603/250 V and 0805/250 V are presently the most common sizes. For higher power, the 1111/500 V may be selected.) • What capacitance value and tolerance is required? (Normally the capacitance value is less than 47 pF. For matching, the capacitance value will be less than 15 pF.) For more information, samples and engineering kits, please visit us at www.kemet.com or call 1.877.myKEMET. SA0612 Copyright © 2012 KEMET
