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.

Murata Manufacturing Co., Ltd. has started mass production of two new multilayer ceramic capacitors for automotive applications—the NFM15HC105D0G3, which is the world’s smallest*1 0402 inch size(1.0×0.5mm) three-terminal low-ESL multilayer ceramic capacitor, and the NFM18HC106D0G3, which is the three-terminal low-ESL multilayer ceramic capacitor with the world’s highest capacitance of 10µF in 0603-inch size(1.6×0.8mm).

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.

EMI is a serious concern for devices that are externally powered (ones that have a plug) or require signal wires that need to extend outside the device (signal wires that might attach to sensors or input/output devices). The wires that connect to power sources, or I/O points, can act as antennas that will allow EMI to be received (coupled onto them) and enter the device.

As DC currents increase along with switching frequencies in applications such as electric vehicles and hybrid electric vehicles, the performance demands on the DC power bus go beyond just the IR drop (i.e. voltage drop) and thermal considerations.
