Knowles Precision Devices products

The AEC-Q200 Ultra-Low ESR X8G range features a highly stable X8R High Q material system, designed to deliver excellent low loss performance. These capacitors, compliant with the AEC-Q200 automotive specification, are optimized to achieve the lowest possible equivalent series resistance (ESR). The electrode system within these capacitors minimizes metal losses, resulting in improved performance curves and reduced losses at higher frequencies. This product supports an extended operating temperature range from -55°C to +150°C, meeting the demands of modern high-density microelectronics. Suitable for high-frequency applications requiring economical and high-performance solutions, the capacitors have a typical temperature coefficient of 0 ± 30 ppm/°C and an insulation resistance time constant of 100GΩ or 1000 seconds, whichever is less. Their Q factor exceeds 2000 at 1MHz, making them apt for various technical applications.

The Ultra-Low ESR "H" range offers a very stable X8G High Q material system that provides excellent low loss performance. Optimized for lowest possible ESR, the electrode system provides low metal losses resulting in flatter performance curves and reduced losses at higher frequencies. An extended operating temperature range of -55ºC to +150ºC accommodates modern high density micro electronics requirements. This range of high frequency capacitors is suitable for many applications where economical, high performance is required.

Designed for power electronics operating in high-temperature environments such as electric vehicles or industrial applications, Hiteca™ multilayer ceramic capacitors (MLCCs) offer a solution that eliminates the need for cooling systems, which can add weight and increase the overall product footprint. These capacitors deliver low losses and provide high, stable capacitance even at maximum voltage and temperature. The patented dielectric system ensures a capacitance aging rate of 0% per decade and a typical capacitance reduction of less than 45% at full rated voltage. Their non-piezo construction makes them suitable for applications like DC bus smoothing and snubber capacitors. Additionally, with lower self-heating properties and low loss operation, Hiteca™ MLCCs can handle higher ripple currents than conventional ceramic capacitors, making them suitable for ensuring the performance and reliability of power electronics across various operating conditions.
