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.
Vishay Intertechnology introduces a new series of surface-mount AC line rated ceramic disc safety capacitors that are the industry’s first such devices to offer a Y1 rating of 500 VACand 1500 VDC. Designed to withstand harsh, high humidity environments, the Vishay BCcomponents SMDY1 series devices offer industry-high capacitance to 4.7 nF.
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.
This guide introduces TDK technical support using Power Integrity (PI) simulations aimed at reducing the impedance of power-supply lines and the quantity of decoupling capacitors necessary through the replacement of two-terminal Multi Layer Ceramic Capacitors (MLCCs) with low-ESL capacitors.
There are several options of technologies for safety capacitors. In this webinar, we will look at the purpose of EMI filter capacitors and what it means to be a “safety” capacitors as well as when to use ceramic technologies and their advantages.
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.
In applications in which energy conservation is critical, such as wind or solar inverters or electric-vehicle (EV) powertrains, distributing power at high voltage can help to reduce I2R losses. The DC link supplying the inverter can be 3 V to 400 V in an EV application, for example, or even higher for wind or solar-power conditioning. However, high operating voltages like these bring additional safety challenges not only for end users but also for components — even those with a suitable voltage rating stamped on the case.
With the continuing supply shortage for multi-layer ceramic capacitors (MLCCs), designers are being forced to consider alternatives. In this article, we will look at the factors to be considered if you’re thinking about using polymer capacitors as a replacement.
There has been a supply shortage of MLCCs since the end of 2016 and there are no signs of immediate improvement.
