Multilayer ceramic capacitors are placed near IC devices mounted in a smartphone or wearable device for the purpose of decoupling. With the trend toward thinner devices, improved functionality, and larger battery size, the mounting area available for parts is shrinking. There is a need for increasing the mounting density, such as mounting low-profile parts at the back of the IC package, rather than the conventional method of mounting parts on the substrate.

Coilcraft’s 0603DC Series achieves the industry’s highest Q factors in 0603 sizes for super low loss in high-frequency circuits. They also feature wire-wound construction for extremely high self-resonance – up to 11.4 GHz – and achieve DCR as low as 29 mΩ, significantly lower than other inductors this size.

Why low ESR matters in capacitor design

A practical capacitor is a non-ideal component. Its circuit model contains series inductance (ESL) and series resistance (ESR). Although equivalent series resistance is often shown in circuit models as a constant value, it varies depending on operating conditions. ESR is resistance from a combination of energy loss mechanisms under specific operating conditions.

Knowles Precision Devices are expanding its V-Series of single-layer capacitors by 100nF capacitor. In RF bypassing applications, the 100nF can help eliminate supply line noise. High-frequency monolithic microwave integrated circuit (MMIC) amplifiers with broadband gain need to be protected from RF noise on supply lines. Supply noise can mix with RF signals, impacting signal-to-noise ratios and potentially causing spurious output. A bypass capacitor provides an efficient path to the ground for RF energy on the supply line before it enters a gain stage.
