2. the 220-10L is a vishay [email protected] (10V surge) the other part, the 10 35L is most likely a Chinese copy of a vishay capacitor (that might be sold as various brands, like xicon) 10uf @20V (35v surge) You always have to keep in mind its surge and when design with these capacitors. They have a tendency to short out with inrush current.

Tantalum capacitor failure modes have been discussed both for the standard manganese dioxide cathode and the new conductive polymer (CP) type. For standard tantalum in the normal operation mode, an electrical breakdown can be stimulated by an increase of the electrical conductance in channel by an electrical pulse or voltage level. …

Tantalum capacitors are made with capacitance values ranging from 1nF all the way to 72mF and they are much smaller in size than aluminum electrolytic capacitors of the same capacitance. The voltage rating for …

around a Tantalum wire to make a Tantalum "slug". The term "slug" is used in the Tantalum capacitor manufactur-ing industry to refer to the Tantalum anode element. The riser wire will eventually become the anode connec-tion to the capacitor. Figure 3 shows an SEM picture show-ing how the particles have been bound together. Figure 3 SEM ...

Location. South Bend, IN. Mar 28, 2014. #1. I bought two 486 boards recently, a DTK PKM-0038s and a PKM-0037s. The 0038s has been great and is in a build now (details in a different post). I'm rather worried about the 0037s. It is covered in tantalums. I have heard that those are likely to fail in an explosive way after 20+ years.

However, I wonder whether it is really necessary to replace ALL Tantalum Capacitors (I find varying feedback: most say : leave them alone, they are very robust). ...

1. We are using some tantalum capacitors for some products. for two purpose: Bulk Capacitor. Low ESR for MCU power. Recently, we are suffering to get tantalum capacitors. Our supplier is saying that Chinese electric vehicle companies are using huge amount of these. So it makes the shortage of tantalum capacitors.

The lower ESR allows a ceramic capacitor with a lower capacitance value to easily replace a tantalum capacitor without any loss of functionality, according to Murata. Average lead times for the standard GRM Series of ceramic capacitors, which offers a capacitance range from 0.5 picofarad up to 47 microfarads, is about 10 to 12 weeks.

I therefore suggest replacing tantalum capacitors with the film variety. As previously stated, if the ESR was crucial to damp a circuit, then a 1 to 3 Ω resistor could be placed in series with the film capacitor to match the ESR of the original tantalum. But, aside from the LDO regulators, that issue is not likely to arise.

Whenever lifetime reliability, temperature stability, or size are of paramount importance, one should consider replacing aluminum electrolytic capacitors in a design with MLCC's or tantalum devices. Multiple MLCC's may be necessary to achieve the required capacitance, and the bill of material costs might require adjustments for …

Dry tantalum capacitors (tantalum electrolytics) don't degrade over time like aluminum electrolytics do. IF the outer coating is intact you don't need to replace them. They are very reliable when …

It states in the datasheet that ceramic capacitors are what can be used but it also states that tantalum capacitors can also be used. It never says anything about being able to use aluminum electrolytic capacitors. ... Replacing aluminum capacitor by tantalum capacitor for accelerometer bulk bypass. 14.

Running an electrolytic significantly below its rated voltage can cause spotty erosion of the dielectric. This can lead to earlier failure. Still, the capacitor will likely last longer than the tantalum cap you took out. I wouldn't worry about it. As for value, anything from 0 to 15uf would most likely work fine.

Tantalum capacitors with polymer electrolyte — The suggested voltage derating should be 10 % (i.e. apply no more than 9 V on a 10 V rated capacitor) for capacitors with a voltage rating of 10 V or less. ...

IMO, ALL tantalums should be replaced. All audio path capacitors should be polypropylene wherever possible----above ~2.2uF, size becomes a real factor. For those larger values, use Nichicon ES bipolars---they have the …

Also with the 22µF value and 470 resistor, the F3 cut-off is ~15Hz (somewhat high); you can increase to 47µF (F3=7.2Hz) or 100µF (F3=3.4Hz). Vintage Marantz phono stages often specified a tantalum capacitor in this position; presumably due to the low ESR of tantalum capacitors.

Replacing Aluminum Electrolytic Capacitors with Tantalum or Ceramic Capacitors Teddy Won AVX Components Corporation One AVX Boulevard Fountain Inn, S.C. 29644 USA Abstract Like all capacitors, electrolytics (e-caps) are based on the principle of storing energy in an electric field using a voltage applied across a dielectric.

If you just need the drive to recover the data, any half-decent electrolytic (including tantalum) capacitor will likely do the job long enough until you finally scrap the drive. Don't worry too much about the ESR. As …

113 1 8. General note: ESL and ESR aren't the only "nonidealness" measures for a capacitor. One that's often overlooked is nonlinearity, usually quantified via THD. In that regard, both tantalum and ceramic are among the worse types, with some ceramics being really really bad. – leftaroundabout.

Tantalum capacitors are often used as the capacitor connected to the power line of PA(=Power Amplifier) for GSM on smart phones. In this report, we evaluate replacing the tantalum capacitor (Ta-Cap) with a ceramic capacitor.

For example, a converter designed to accept DC input up to 24V, and using ICs/semiconductors rated to, say, 30-35V, will die once you replace the electrolytic input caps with ceramics, as the circuit will now see at least 48V input peak in a hotplug situation, almost guaranteed failure.

When replacing tantalum caps with MLCCs, one should consider more than just matching the capacitor value. Matching the ESRs can also be very important, depending on the application circuit. For …

Tantalum capacitors increases distortion because the capacitance alters with (a) applied DC bias voltage, (b) applied AC voltage, and (c) frequency; the effects are consequently non-linear (higher on one side than the other) and thus harmonic distortion. The THD of a tantalum capacitor exceeds that of ceramics, which are awful.

If the solder reflow occurs in less than 1 s to 1.5 s, this indicates that the tip temperature is excessive. If more than 3 s to 3.5 s are needed for solder reflow, either the tip temperature is insufficient or the tip is cooling down when applied to the circuit board. Apply a small amount of flux to the component termination and the pad layout.

If you want to replace them, you can use a ceramic capacitor with a small series resistor of similar ESR to the original tantalum capacitor the designer says you "must" use (probably in the 1-3 $Omega$ range).

In most instances where a tantalum capacitor is used for decoupling, a ceramic capacitor should be able to replace it if it fits in the space. However, replacing a tantalum capacitor with a ceramic capacitor would not be a smart idea if the tantalum capacitor is used for audio coupling or timing. What Is the Advantage of Tantalum …
