KEMET KPS Series Multilayer Ceramic Capacitor, 22µF 50V, X7R, 2220

The KEMET KPS Series represents a significant advancement in surface mount Multilayer Ceramic Chip Capacitor (MLCC) technology. By utilising proprietary lead-frame technology, it vertically stacks one or two MLCCs into a single, highly compact surface mount package. This innovative design mechanically isolates the capacitors from the printed circuit board (PCB), delivering superior performance against thermal and mechanical stresses that can compromise reliability in demanding applications.

This isolation is not just about physical resilience; it directly addresses the issue of audible, microphonic noise, which can occur when a bias voltage is applied to standard MLCCs. The KPS series effectively minimises this undesirable effect, making it ideal for sensitive electronic circuits. A key benefit of the two-chip stack configuration is the ability to offer up to double the capacitance within the same—or even a smaller—design footprint compared to traditional surface mount MLCCs, enabling significant board space savings without sacrificing performance.

Engineered for robustness, the component provides exceptional board flex capability of up to 10mm, protecting solder joints from cracking during assembly or operation. It features extremely low Equivalent Series Resistance (ESR) and Equivalent Series Inductance (ESL), ensuring efficient power delivery and high-frequency performance. As a non-polar device, installation is straightforward, minimising the risk of errors. The series is environmentally friendly and fully compatible with lead-free (Pb-Free) reflow soldering profiles, meeting modern manufacturing standards.

With its combination of high capacitance density, advanced stress protection, and noise reduction, the KEMET KPS capacitor is a critical component for enhancing the reliability and performance of sophisticated electronic systems.
