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.

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.

Advantages and disadvantages of MLCC downsizing are discussed in AVX technical papers written by Frank Hodgkinson and Maureen Strawhorne. As integrated circuits (ICs) continue to pack more functionality into smaller packages, the need for bulk off-chip capacitance remains. In resonant circuits, such as phase-lock-loops (PLLs) and switching regulators, precision class one ceramic capacitor may be required.

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.
