爱华网贴片保险丝_贴片保险丝 -贴片保险丝
贴片保险丝在小型保险丝行业中是技术含量相对较高的新品种。贴片保险丝可分为贴片电流保险丝和贴片自恢复保险丝。VICFUSE贴片保险丝其中贴片电流保险丝按尺寸和性能又可分为如下形号：
（1）、产品按尺寸可分类为：0402、0603、1206
（2）、产品按性能可分。类为：快速熔断、慢速熔断和增强熔化热能三种类型。 JEPSUN贴片保险丝快速熔断系列适用于保护电路中快速反应的重要器件，一般很少发生浪涌电流的场合；慢速熔断系列适用于电路中常有较大的浪涌电流发生的场合；增强熔化热能系列是介于两者之间，有较强抗浪涌能力又比较经济的场合。
贴片自恢复保险丝按尺寸又可分类为：0402、0603、1206、1812、2920等。
贴片保险丝VICFUSE贴片保险丝如果具有高要求，一般采用薄膜制程，超低内阻，适用于过流保护，如浪涌等。电脑周边产品，手机等通信设备，数码相机，显示器，电池常用。可以用这类技术生产的厂家均有一定规模，如捷比信贴片保险丝等。
贴片保险丝可分为一次性贴片保险丝和贴片自恢复保险丝，一次性保险丝保护后需要更换，自恢复保险丝保护后断电可以自己恢复能重复使用

贴片保险丝_贴片保险丝 -使用方法
微型保险丝的实际使用场合，仅仅依据UL规格条款来选定保险丝是远远不够的。
1．在选择时必须考虑的几个问题 : 在了解了所使用电路的参数基础上，按下面几个方面来选定保险丝：常态电流、熔断电流（希望使之熔断的电流和时间）、开路电压、短路电流、冲击电流（没有被切断的电流、时间和次数）、环境温度。
①常态电流：首先我们必须知道，在所使用的电路中流经保险丝的常态电流大小。通常情况下我们要预先设定一个减额量，然后按下面的原则来进行选择：即常态电流必须小于额定电流与减额系数的乘积。
②熔断电流：按照UL规格的规定，保险丝应在额定电流2倍的情况下快速熔断。但在大多数情况下，为了确保可靠地熔断，我们推荐熔断电流应大于额定电流的2.5倍。另外熔断时间是重要的话，还必须参考厂商提供的熔断特性图来作出判断。
③开路电压：开路电压一般应选定为小于额定电压。例如将额定电压为DC24V的保险丝用于AC100V的电路中时，有可能引燃保险丝或使保险丝破裂。
④短路电流：我们把电路短路时流过的最大电流值称之为短路电流。对于各种保险丝来说，额定断路容量是有规定的，我们在选择保险丝时必须注意不要使短路电流超过额定断路容量。如果选择了断路容量小的保险丝，则有可能使保险丝破裂或者引发火灾。
⑤冲击电流：观测冲击电流的波形（脉冲电流波形），用I2t值（焦耳积分值）来计算它的能量。冲击电流的大小和次数不同，对保险丝造成的影响也是不同的。冲击电流的I2t值与单脉冲的熔断I2t值之比决定了保险丝耐冲击电流的次数。
2．具体的选择方法下面所列为参照图2的波形和参数值来选定保险丝时的一个实例。
①常态电流：对于常态电流为1.2A，使用减额系数为75[%]的保险丝时，我们必须选择额定电流大于1.2A÷0.75=1.6A的保险丝。
②熔断电流：为了确保熔断电流大于额定电流的2.5倍，我们必须选择小于5A÷2.5=2A额定电流值的保险丝。综合①与②两点，我们应该把1.6～2.0A保险丝作为选择对象,从耐脉冲性能好这点出发,应选定2.0A的较为有利。
③开路电压和短路电流：选择额定电压大于12V、短路断路容量大于25A的保险丝，JAD型、KAB型和KAC型都符合使用条件。
④冲击电流：计算冲击电流的I2t值（焦耳积分值）。冲击电流为三角波时可以按下式计算：通过厂商提供的焦耳积分值－时间特性图，我们可以查阅到1ms时的I2t值，这是一个在单脉冲情况下熔断的I2t值。3．其他需要注意的问题在实际使用中，微型保险丝对安装条件、耐化学性能、耐超声波清洗性能等各方面有什么特殊的要求和问题，必须事先通过厂商进行确认。微型保险丝同贴片电阻和贴片电容等普通的电子元器件不同，由于生产厂家的差异，其规格有较大的差别，另外实际安装时对印制板的散热和配线散热都会带来一定的影响，因此对微型保险丝的选定是否确当，最终还是应由产品的状态来予以认定。贴片式微型保险丝的规格与形状结构1．规格大多数微型保险丝都获得了美国国度安全规格地UL248-14认证，这种规格规定了下述这些内容：
①通电容量：按额定电流通电1小时不熔断。
②温度上升：按额定电流通电时地温度上升<75℃。
③熔断实验：在通以2倍额定电流状况下，1分钟之内熔断。
④断路容量：加上额定断路容量时，不会连续地产生飞弧或引燃。
2．形状与结构微型保险丝地形状有引线型和片型之分，假如按保险丝元件地结构来分地话，又能够分为线形和薄膜形。图1为日本松尾电机公司生产地微型保险丝地外形和结构。表1所示为它们地特性和额定值。表中断路特性一栏“24V/50A”地含义是：即使加在电路上地最大电压为24V，并使电路短路时流过地最大电流为50A，保险丝依然能够确保使用上地安全。假如超过“24V/50A”，则有能够产生连续地飞弧而无法切断电路，或许还会惹起外壳破裂。
①JAD型：3216，线形具有优秀地耐脉冲电流特性，适用于冲击电流较大地电路中。
②KAB型：2012/1608，薄膜形体积小、额定电流范围宽，是便携式电子设备中最理想地保险丝。③KAC型：1005，薄膜形超小型，具有优秀地耐脉冲电流特性。
