Re: Teapo capacitor quality in hot country''s or 24/7 builds, you want the psu fan doing what it''s designed to do - move a lot of air. non of that wisper/thermal management shit - it''s a psu killer. take the fan out and hook it to 12v - if it feels like it moves a lot of air - use it.

Increasing demand for quality capacitors has been seen in the marketplace over the past several years. It seems that many manufacturers have cut corners on material quality and manufacturing processes so that, even though capacitors test well off the shelf, they don''t last more than 6 to 12 months in the field.
Capacitor Quick Reference Guide The table on the next page provides a brief summary of different capacitor types and their relative merits, arranged approximately in terms of decreasing quantity (or increasing quality) of capacitance offered by each type.
Understanding the Q Factor of a Capacitor. Q factor, or Quality factor, is a crucial parameter in assessing a capacitor''s performance in AC circuits. Essentially, it quantifies the efficiency of a capacitor by evaluating the ratio of its reactance to its equivalent series resistance (ESR). Key Concepts:
Where E is the electric field, F is the force exerted on a particle introduced into the field and q is the charge of the particle. The unit for electric field is volts per meter [V·m-1] or newtons per coulomb [N·C-1]. Q Factor The quality factor or Q factor of a capacitor, represents the efficiency of a given capacitor in terms of its energy losses.
For how capacitors indicate these values, check out this guide to capacitor code markings. A Fundamental Passive Component Along with resistors and inductors, capacitors act as one of the fundamental passive …

Quality Factor of Capacitor: The quality factor of a capacitor is the ratio of its reactance to its series resistance, given by Q = 1 / (ωRC). Lossy Capacitor: A lossy capacitor can be modeled with a capacitance and high …
Reason seems to be the huge difference in quality for these capacitors. And more often than not, replacing caps actually solves the problem. Now it occurred to me that some devices just appear to live forever (knock on wood), where others fail in two or three years. With new brands coming and old brands going, compiling a list of good/bad ...
In other words, Q factor tells us how good a capacitor is at its job at a certain frequency. A high Q value indicates low energy loss during operation, making these capacitors a good fit for applications requiring low power …
Introduction to Capacitors – Capacitance The capacitance of a parallel plate capacitor is proportional to the area, A in metres 2 of the smallest of the two plates and inversely proportional to the distance or separation, d (i.e. the dielectric thickness) given in metres between these two conductive plates. ...

Samxon capacitor quality discussion (spin-off from OCZ Bug Zapper thread) As you see in the small comment I added to the OP I spun off the thread here. I found the discussion highly interesting and worthy of it''s own thread so we would not hijack SgtRock''s original thread.
The biggest issues for selecting the good quality electrolytic capacitor are that: (1)No *economically* good method to evaluate or test the reliability and durability of capacitors when the capacitors arrived at the factory and before assembling to the product. (2)There are so many fake or counterfeit capacitors get *mixed* even going through ...
