是没有冲突,我是想知道是不是所有的安规电容的UL认证都是85度?

UL又是考虑什么而限制这个温度的?

谢谢答复!

UL 1414

Scope
Section 1 effective May 1, 2007
These requirements cover capacitors rated not more than 1.0 microfarad, 85癈, 250 V, and 60 Hz that are employed in radio, television receiving, and similar appliance circuits where breakdown of the capacitor results in a risk of fire, electric shock, or injury to persons.

These requirements also cover gas-tube voltage surge suppressors for use in products rated not more than 250 V, and 60 Hz that are employed in radio, television receiving, and similar appliance circuits where breakdown of the voltage surge suppressor results in a risk of fire, electric shock, or injury to persons.

These requirements cover capacitors and suppressors intended for use in radio- and television-type appliances which conform with the requirements applicable to such equipment.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this Standard, and that involves a risk of fire, electric shock, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements to determine that the level of safety as originally anticipated by the intent of this Standard is maintained. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this Standard shall not be judged to comply with this Standard. Where appropriate, revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this Standard.

我也留个记号.

我以前的认证过程中有碰到过125度的Y1电容的(证书上有写明),Y2就只有85度的了.

不过,对安规电容的温度规定还是不太了解,等待高手解答.

85度是试验的标准温度,至于125度又可能就是最高的承受温度.

谢谢!
以前我用过Y电容只有85度,现在很多公司有认证125度,这应是技术的提升.现有125度的标准.
