Contact factory for info. Johanson Technology's High-Q Multilayer Capacitors are designed for optimal RF performance. Ideal for high-frequency applications, offering low loss and high efficiency.
A High Q capacitor can offer the following characteristics: Low Energy Loss – In many applications, minimizing energy loss is crucial to maintain system performance and efficiency. High Q capacitors exhibit lower energy losses in the form of heat or electromagnetic radiation, which is beneficial in high-frequency or high-power applications.
These Murata High-Frequency Ceramic Capacitors feature low power consumption for mobile telecommunications, the GQM and GJM capacitors come with copper electrodes that allow for ultra-low ESR, high Q in the GHz frequencies, and high RF current handling capability.
It is also important to note that the Q of a capacitor can be managed by carefully choosing the materials and construction of the capacitor. This is because multilayer ceramic capacitors (MLCCs) are made up of alternating layers of ceramic dielectric material and metal electrodes and compressed to form a compact, high-capacitance device.
This characteristic makes them suitable for applications like filters and oscillators, where sharp frequency response and stability are required. Low Equivalent Series Resistance (ESR) – High Q capacitors have a low ESR, which is the resistive component of a capacitor's impedance.

Effect on MIM structured parallel quenching capacitor of SiPMs
Additional MIM quenching capacitors give the opportunity to achieve a high value of C q, which increase the initial current of the single-photon pulse shape in SiPM. As the initial current increases, the PET detector output (the convolution of LSO and single-photon pulse) develops a shorter rise time as shown in Fig. 8 .
