Film capacitor types certainly do have some advantages over their Al-electrolytic cousins; they can have much lower Equivalent Series Resistance (ESR) for the same CV rating, which gives them typically much …
Film capacitors are also known as plastic film, polymer film, or film dielectric capacitors. Film capacitors are inexpensive and come with a nearly limitless shelf life. The film capacitor uses a thin dielectric material with the other side of the capacitor metalized. Depending on the application, the film capacitor is rolled into thin films.
While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a maximum value of 2200 V/µs) making them suited for use in snubber circuits. Film capacitors also have low equivalent series resistance (ESR), low equivalent self-inductance (ESL) and can tolerate large peak currents.
Nowadays we have NP0 ceramic caps, which don't drift their value with the temperature. I usually choose a NP0 capacitor if possible. Tantalum is another low-leakage type that often can make sense to sub with film if its being used as an audio coupling cap. Low-leakage electrolytic is the other choice for a sub.
Film capacitors also have low equivalent series resistance (ESR), low equivalent self-inductance (ESL) and can tolerate large peak currents. Snubber capacitors in series with a small resistor are placed across solid-state switching devices. Snubbers protect the devices from voltage spikes and reduce the rate of rise (dv/dt) across them.
In comparison, polypropylene metallized film capacitors and double-sided metallized film capacitors have a self-healing property, and they are suitable for use in low pulse and medium pulse applications. These two types of capacitors are suitable for protecting various switching devices including thyristors, FETs and IGBT modules.
So here, I briefly explain briefly, the three models are the same and different. From the names, everyone can see that there is an identical place in their names: "CBB". In fact, CBB65, CBB60, and CBB61 belong to the family of polypropylene film capacitors. Also use the thickened metallized zinc-aluminum film as the electrode and medium.

While other capacitor types may be better suited for different applications, the CBB23 capacitor is a top choice for audio crossovers. When choosing capacitors for your audio system, it''s important to consider the specific application and performance requirements. Consider factors such as cost, performance, and reliability when making your selection. With the right …
The smallest film caps are metallized polyester in MKT or Greencap form. These are OK and better than generic electros but the best common types are based on polypropylene film/foil type MKF (huge), or metallized film MKP type (v.large). As a general rule, anything over 1uF in MKF is too big as is anything over 3.3uF in MKP and maybe 10uF MKT.
Film caps are better because they''re more predictable and that means you get the similar results without having to measure and discard some of your caps for being too far out of spec. It also means your crossovers last longer and makes your product more consistent, leading to consistent reviews and recommendations.
That means I will explain how a decoupling capacitor can save my circuit from harmful oscillations. Along the way I will talk about three popular capacitor types, the film capacitor, the ceramic capacitor and the electrolytic capacitor and explain which one is best suited for which application and why. Let''s get started!
Tantalum is another low-leakage type that often can make sense to sub with film if its being used as an audio coupling cap. Low-leakage electrolytic is the other choice for a sub. Mostly that choice depends on value, up to about 10uf at 50v films aren''t too expensive or big but the cost and size goes up pretty quick beyond that point.
On the other hand, the Titan HD has better technology but has a higher price. But it has the most rigorous IEC 60252-1:2001 certification and better compatibility. It also has a greater capacitance allowing better cooling performance for your HVAC system. Also, the Titan Pro HD capacitor warranty covers 5 years after the sale. That is a thing ...
1st choice is [polypropylene film capacitors] ( https://en.wikipedia /wiki/Film_capacitor#Polypropylene_ (PP%29_film_capacitors), which is better than most other types of film. 2nd choice is C0G or NP0 class 1 ceramic capacitors. Avoid class 2 & 3 ceramic caps in signal path! For power rail decoupling/bypass use:

Capacitor performance is better, capacity is more stable! Now let''s talk about their differences. The CBB65 capacitor has an aluminum shell and the inside is made of high-purity …
There are lots of recommendations for the FKP floating around the net. I have tried them a few times in riaa networks and always found them to sound very average. …
Film capacitors excel in high-voltage, high-precision, and high-reliability scenarios, while electrolytic capacitors are the go-to choice for high-capacitance, space …
Key learnings: Capacitor Definition: A capacitor is a basic electronic component that stores electric charge in an electric field.; Basic Structure: A capacitor consists of two conductive plates separated by a dielectric material.; Charge Storage Process: When voltage is applied, the plates become oppositely charged, creating an electric potential difference.

There are lots of recommendations for the FKP floating around the net. I have tried them a few times in riaa networks and always found them to sound very average. Perhaps they do sound better than the MKP but this isn''t saying much. If there are budget constraints i''d rather go for the Mundorf MKP.

Moreover, ceramic capacitors are less sensitive to thermal expansion than film capacitors, so they can withstand temperature changes better. Despite their advantages, ceramic capacitors have a number of disadvantages. Higher frequencies can result in greater losses because of these capacitors'' lower impedance. Furthermore, their relatively slow response …
Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:
