Y2 Safety Standard Capacitors

Y2 Safety Ceramic Capacitor

KNSCHA JT Series Y1( 400VAC) and  JK  Series Y2(300VAC) Safety  Standard  Recognized Capacitors

DONG GUAN AJC INDUSTRIAL CO.,LTD is specialized in producing the Class Y Safety Standard Capacitors. The Y class safety-certified capacitors, used in line-to-ground (line bypass) applications, have voltages from 400VAC (Y1 series)/300VAC (Y2 series). Major features of these non-polar capacitors include capacitance range generally from 100pF to 10000pF; from 7.5mm to10mm lead spacing, high reliability, and kinked or straight lead configurations.

KNSCHA Class Y Safety Capacitors ideal for across the line applications, compact size, cost effective product, safety standards recognized. Following are JT Series  Y1 and  JK Seies Y2 Safety Standard Recognized Capacitors features, applications, specifications and dimensions. We supply high quality Class Y Safety Capacitors to you.

    KNSCHA JT Series Y1( 400VAC) and  JK  Series Y2(300VAC) Safety  Standard Recognized Capacitors Applications

    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

    KNSCHA JT Series Y1( 400VAC) and  JK  Series Y2(300VAC) Safety  Standard Recognized Capacitors Introduction

    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.
