Knowles Precision Devices products

The 'Q' and 'U' ranges of capacitors from Knowles utilize a specially designed High Q material that ensures low loss performance in high frequency systems. These capacitors are engineered for optimal ESR performance, making them ideal for applications demanding both economical and high-performance solutions. The product range covers a variety of case sizes from 0402 to 3640 with multiple termination options, including ribbon leads and tin/lead plated finishes for specific requirements. Notably, select parts have been independently characterized by Modelithics and are included in their model library, readily compatible with most design software suites. These capacitors are designed to operate between -55°C to +125°C or up to 175°C (H17 variant). They exhibit a typical temperature coefficient of 0 ± 30 ppm/°C (C0G/NP0) and offer high insulation resistance exceeding 100GΩ at +25°C. The Q factor is greater than 2000 at 1MHz, reinforcing their suitability for high-frequency applications.
