Class Y capacitor is divided into Y1 capacitors and Y2 capacitors, Y1 is a double insulated Y capacitor, used to cross the one or two side of the.Y2 is a basic single insulation Y capacitor, used to cross the primary side of the earth to protect the FG line. An adjustable capacitor is used for such occasions, which is, after the capacitor failure, will not cause electric shock, and does not endanger personal safety.

JYA Y1 CD safety standard recognized capacitors, used in line to ground applications—the capacitor placed between line and ground, have voltages from 400VAC. Major features of these non-polar capacitors include capacitance range generally from 10pF to 10000pF; from 7.5mm to10mm lead spacing, high reliability, and kinked or straight lead configurations.

In general, the Y class safety-certified should be connected to a wire with large noise interference. You can use Class Y Safety Standard Capacitors in line disturbances suppression, motors, motor controls, relays, switching power supplies, Inverters with compact size, cost effective product, and safety standards recognized.

If you heard many good comments of our JFV X2 MKP series, then please don't miss this important information.
JFV series is going to discontinued in this July. Due to technology improved, now jb is focus on another Class X2 MKP series -JFW.

JFW safety reach to 310VAC and provides interference suppression capacitor with VDE, ENEC and UL approvals.

JFW series has sell in market for 2 years, we received lots good review from market, JFW can safety replace with JFV without any problem.
Especially JFW series offer is better than JFV series! Better price, shorter delivery date and flexible MOQ.

Welcome to check our JFW Datasheet link here and send your exact inquiry to us, let we help you cost down!
If you can't find your demand specification, we can also custom for you.

Dear Friends:

Let’s tell you more about our JYA and JYC series Ceramic capacitor’s application today, please find details as below: 

JYA--Y1 and Y2 Safety Standard Recognized Capacitors
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.)
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.

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….

JYC--High Voltage Ceramic Radial Type Disc Capacitors
Applications: High Voltage Ceramic Disc Capacitors are specially designed for high voltage applications, such as:

• DC-DC converters, Voltage multipliers.
• Radio and TV receiver, Modems, Interfaces, TV and monitors.
• Other electrical appliances where high voltage is present.
• High voltage power supplies, HV power supplies.
• Electrostatic coating, Arc spray and sputtering, Electrostatic cleaning power supplies, Ion generator power sources.
• High voltage power supplies for x-ray sources and pulsed lasers: Baggage scanner, Medical x-ray, Industrial laser.

If you have capacitor demands, please send us inquiry list for quote, we’ll not let you down, thank you.

Dears,

I am sorry to inform you we decided to discontinue JFV X2 MKP series from July 1st of 2019.
We have updated JFV X2 to JFW X2 thoroughly.
Please buy from us JFW X2 series to replace of JFV in future.
We have informed the changing schedule for quite a long time as you know.
Almost of our customers had followed the changes and shifted the order to JFW X2 already.
We do appreciate the great support very much!
Now in order to simplify our production lines and improve the working efficiency, we would like to let you know our deadline for JFV series.

Below you will find our clarification between JFV and JFW.Here please find difference between JFW and JFV:

1> JFW is 310VAC X2 MKP Film Capacitors with ENEC, VDE, UL approvals, while JFV X2 is 275VAC.
2> JFV and JFW series are both produced by jb Capacitors, while we have better production flow for shorter production time and with higher voltage for JFW series. We jb Capacitors confirm that JFW can replace of JFV without any problem.
3> Both JFW and JFV are 110’C. JFW certification marked 105’C but it can reach 110’C actually. Thank you for your kind attention and your continuous support!
