I have a datasheet that calls for "a 15 pF capacitor with Self-Resonant Frequency in the 1800/1900 MHz range". It then recommends a capacitor (Murata GRM1555C1H150J) that (so far as I can tell) from the datasheet doesn''t specify it''s SRF.
High voltage front-end connections to the power source typically rely on aluminum capacitors, while intermediate step-down voltages often look towards the tantalum and ceramic families to take advantage of volumetric efficiency. The final load decoupling and bypass capacitors are generally found in the ceramic and film families. 2 SURFACE MOUNT CAPACITORS FOR DC

The capacitor self-resonant frequency causes your capacitor to stop behaving like a real capacitor and start behaving more like an inductor at high frequency. This important effect is unnoticeable at low frequencies, but it becomes a major problem related to signal integrity, power integrity, and impedance matching at high frequencies.

Choosing and Using Bypass Capacitors APPLICATION NOTE AN1325Rev 1.00 Page 1 of 11 Oct 10, 2011 AN1325 Rev 1.00 Oct 10, 2011 Introduction Bypass capacitors are found in every working piece of electronic equipment.

In the frequency domain the view of the internal impedance of the capacitor is a "trough" where the beginning (zero) of the trough is dictated by the capacitance value and the end (pole) is from the parasitic-inductance. The lowest point of

For example, all film capacitors have an intrinsic self-healing mechanism, but this can be enhanced by using special patterning within the metal electrode system, such that the total capacitor surface area is divided into parallel microelements that prevent short-circuit failure. Exposure to prolonged high temperatures and applied voltages will reduce the capacitance
Compared with previously-reported flexible devices, our supercapacitor revealed great mechanical flexibility and self-healing ability, endowing it with high deformation ability
Capacitor Type. In high frequency circuits, the lead inductance of the bypass capacitor is an important factor. When switching at high frequencies like > 100MHz, a high frequency noise is generated on the power rails and these harmonics in power supply in combination with high lead inductances will cause the capacitor to act as an open circuit. This
a higher ESL. Therefore, its self-resonance frequency decreases and the impedance increases in the high frequency region. On the other hand, a capacitor with smaller capacitance generally has a smaller size, leading to a lower ESL. Therefore, its self-resonance frequency is high and a low impedance is obtained in the high frequency region. However,
Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.
A bypass capacitor eliminates voltage droops on the power supply by storing electric charge to be released when a voltage spike occurs. It also provides this service at a wide range of frequencies by creating a low-impedance path to ground for the power supply. What size bypass capacitor do we need?
The first line of defense against unwanted perturbations on the power supply is the bypass capacitor. A bypass capacitor eliminates voltage droops on the power supply by storing electric charge to be released when a voltage spike occurs.
Most engineers know that systems, circuits, and individual chips need to be bypassed. The methods for choosing bypass capacitors typically follow decisions of tradition instead of optimizing for any particular circuit. This application note aims to bring the design aspect back to this seemingly simple component.
The increase in self-healing efficiency of the supercapacitor is ascribed to that the highly healable PCH electrolyte not only rapidly restores its conductive paths, but also offers ions to promote the self-healing behavior of the PPH 0.03 electrode.
As shown in Example 2, it is common to use at least 2 bypass capacitors in parallel. Two capacitors reside on the positive and negative supply. The smaller value capacitor appears in a smaller package and is placed closer to the device. Figure 20 presents the bypass capacitors C1 through C4 of the ISL1557.
