WEET Y2 CE 300VAC Safety Standard Y Recognized Capacitors Y5P Y5U Y5V Line-to-Ground Capacitors

WEE Technology Company Limited - WEE are Capacitors Specialist

Class X2 and Y2 are the most commonly used safety-certified capacitors. Whereas X2 and Y2 caps are appropriate for household applications, X1 and Y1 safety capacitors are used in industrial settings. Y Capacitors: Also known as "line to ground capacitors" (line bypass.) WEET Y capacitors are used in applications where failure of the capacitor could lead to the danger of electrical shock to the user, if the ground connection is lost.

WEET Y1 CD 400VAC Safety Standard Recognized Capacitors 7.5mm 10mm Lead Spacing Class Y Filtering

WEE Technology Company Limited - WEE are Capacitors Specialist

WEET Class Y Capacitors: These capacitors are rated for use in situations where failure would present an electric shock risk. What this means is, Y class capacitors are designed to simply not fail at all, or be self-healing, allowing them to recover from an arc-over event. Basically, the requirements for a class Y capacitor are stricter and higher than that of an X Capacitor. And Y capacitors are the only capacitors rated to be safely used in 'line-to-ground' situations. However, again, there is not any mention about their failure mode; the Y rating only implies certain minimum requirements are met. This amounts to not failing at all generally, or, as mentioned, being self-healing.

WEET Y1 CD 400VAC Typical Applications : Line disturbances suppression, Motors and motor controls, Relays, Switching power supplies, Inverters, Line-to-line (Class X) filtering, Line-to-ground (Class Y) filtering, Antenna coupling, Primary and secondary coupling, Network and security protection, audio visual product,, Home Appliance, new energy, Industry automation, LED

WEET WMF Precise Audio Capacitors Testimonials From Audiophiles and Audio DIY Hobbyist

WEET WMF Precise Audio Film Capacitors Test Report and Testimonials From Audiophiles and Audio DIY Hobbyist

"I have indeed installed the WEET WMF capacitors,  as replacements in two speaker crossovers. The difference was quite apparent right away, and I expect it to get better as the caps settle in. 

What I did notice is that sound in the midrange region became less forward, less flat and hard. The soundstage expanded in three directions, height, width and depth. The highs seem better defined but at the same time a papery, whispery quality, which I believe is in the nature of the tweeter of this speaker, became more audible on certain musical pieces.

More listening time is needed to be sure of my impressions. I do think, however, that these capacitors can be used successfully in speakers of very high quality, even better than the ones I tried.

The speakers I upgraded with the WEET WMF capacitors pair are a pair of NHT Model 1A. I am sure the WMF caps would be appropriate for other, more refined makes and models. My next project is to upgrade a pair of Dynaco A25, but unfortunately there is no WMF model with the correct 5uF value. I shall use Clarity Caps instead.

I have a little experience with different makes of equipment. I participate in the review panel of a hi-fi magazine ( UHF Magazine ), and learned to listen carefully to a good speaker. My present speakers are ATD Capriccio Continuo… Admonitors.

The open sound and non-agressive highs I noticed after installing the WMF caps, are typical of speakers much more expensive than the NHT Model 1A.

One welcome characteristic of the WMF caps was their relatively small size. They were not drop-in replacements for the tiny electrolytics in the original NHT crossover, but I found a convenient way to fit them in.

The upgraded NHT 1As are now back with their owner and the caps should have finished running in. I hope to get a listening session with them fairly soon, and I shall let you know any further impressions then."

WEET WMF 6.8uF 630VDC Precise Audio Film Capacitors Common Values Table Reference

WEE Technology Company Limited - WEE are Capacitors Specialist

We offer very low ESR, very low dissipation factor: ≤0.0005 1KHZ, the leads are tinned pure coper wire.
WEET WMF is very excellent replacements of Mundorf, Jantzen Audio, Auricap, Solen, ERSE, etc…but important is prices are much more attractive.
Compared with WME, WMF has much lower inductance and much lower Dissipation Factor, very goods sound effect.
