TS18Q – RF Multilayer Ceramic Capacitors with High Q and Low ESR

In high-frequency or microwave circuit design, choosing the wrong capacitor can lead to signal distortion, frequency drift, or even overheating and failure of the entire module.

The Suntan TS18Q series MLCC is specifically engineered to prevent these problems — delivering high Q factor, low ESR, and reliable performance using COG dielectric. It’s the go-to solution for engineers seeking performance and for procurement professionals looking for dependable sourcing with traceability.

Whether you are solving design challenges or sourcing components for mass production, TS18Q helps you get it right the first time — reducing back-and-forth communication and minimizing costly rework.

Common Design & Procurement Pain Points – Solved by TS18Q

Common Issue How TS18Q Solves It
Signal distortion or RF power loss Q factor >2000 @ 1MHz ensures minimal loss and clear signal integrity
Performance instability due to temperature fluctuation COG material with 0±30ppm/℃ guarantees capacitance consistency
Overheating or low efficiency in high-frequency modules Low ESR design reduces heat and power consumption
No small-size capacitors that support RF up to 3GHz Multiple compact SMD sizes (0603 to 3838) fit space-constrained layouts
Need for custom specs or special part numbers Customization available on request — ideal for RF design flexibility
