Murata Co., Ltd. has developed the world's first ultra small 006003 inch (0.16mmx0.08mm) multilayer ceramic capacitor. Compared with the existing ultra small product 008004 inch (0.25mmx0.125mm), the volume has been reduced by about 75%.
Murata Manufacturing Co., Ltd. (hereinafter referred to as "Murata") has developed Murata's first multi-layer ceramic capacitor with a size of 1608M (1.6 × 0.8mm) and an electrostatic capacity of up to 100 µ F (hereinafter referred to as "this product"). The "GRM188C80E107M" with a rated voltage of 2.5Vdc, a working temperature of up to 105 ° C, and a temperature characteristic of X6S (1), and the "GRM188R60E107M" with a working temperature of up to 85 ° C and a temperature characteristic of X5R (2) have started mass production. In addition, the product (3) with a rated voltage of 4VDC and a working temperature of up to 85 ° C is planned to start mass production in 2025.
BUSSMANN supercapacitors are made of a unique double electric layer capacitor (EDLC) structure and high performance materials. These supercapacitors feature ultra-high capacitance, high specific capacitance, low equivalent series resistance (ESR), and long cycle life, making them suitable for a variety of applications.
The battery charger PCA9482 chip is a 7A 2:1 single cell battery switch capacitor charger chip IC. PCA9482UK is a highly integrated switch capacitor converter with an embedded OVPFET that provides twice the output current for fast charging applications using single cell batteries. This device can operate in a 2:1 switching mode, with very high efficiency (>96.5%, at VVOUT=4V, IVOUT=5A), and can run in a 1:2 switching mode or in a forward and reverse 1:1 mode.
NXP's TEA19363T is a member of the GreenChip series of switching power controller ICs. It aims to enable the flyback topology to be used independently on the secondary side or in conjunction with USB PD or intelligent charging controllers (such as the TEA190x series). The built-in green function provides high efficiency at all power levels.
The TEA19363LT is a member of the GreenChip family of controller ICs for switched mode power supplies. It is intended for flyback topologies to be used either standalone or together with USB PD or smart charging controllers (like the TEA190x series) at the secondary side. The built-in green functions provide high efficiency at all power levels. The TEA19363LT is compatible with multiple output voltage applications with a wide output range from 5 V to 20 V in Constant Voltage (CV) mode. When used with a secondary-side controller IC, like the TEA190x series, it supports Constant Current (CC) mode down to 3 V output voltage.
TEA1708 is an IC suitable for automatic discharge of X capacitors, with low power consumption characteristics (typical value of 1 mW at 230 V (AC)). Internally integrated with a 500 V clamp circuit, it can protect the IC during power surges. In typical applications with only two 200k Ω resistors, the maximum allowable differential mode surge voltage exceeds 6 kV. No metal oxide varistors are needed to protect the IC. The discharge current of the X capacitor is internally limited to 2.3 mA. Use low-voltage capacitors to set a discharge delay timer externally. Extremely low power consumption combined with high discharge current, large capacity X capacitors can be used to reduce EMI while maintaining low standby power consumption.
Murata Manufacturing Co., Ltd. has developed a new low loss multilayer ceramic capacitor (MLCC) that supports a rated voltage of 100V and has an ultra small size of 0402M (0.4 x 0.2mm). It is mainly used for wireless communication modules and will begin mass production in February 2024.
Recently, the team of Shao Tao, a researcher at the Institute of Electrical Engineering of the Chinese Academy of Sciences, has made progress in using discharge plasma to improve the film performance of energy storage capacitors.
