自恢复保险丝选型指南

自恢复保险丝选型指南自恢复保险丝是一种重要的电气保护设备，主要用于在电路发生过载或短路时切断电流，以保护电器设备和电路的安全。

选择适合的自恢复保险丝类型对确保电路的正常运行至关重要。

本文将提供一个自恢复保险丝选型指南，帮助读者了解不同类型保险丝的特点和应用场景，以便根据实际需求选择合适的保险丝。

首先，我们需要了解什么是自恢复保险丝。

自恢复保险丝，也被称为PTC保险丝（正温度系数保险丝），是一种基于正温度系数（Positive Temperature Coefficient，PTC）效应的电阻材料制成的保险丝。

当电流通过保险丝时，保险丝的温度上升，电阻值随之增加，并限制电流的流动。

一旦过载或短路情况解除，保险丝会自动恢复到正常状态，电流继续流动。

因此，自恢复保险丝不需要更换，能够提供长时间的可靠保护。

1. 电流额定值（Current Rating）：根据电路中的电流需求选择适当的电流额定值。

保险丝的额定电流应略高于电路中的最大工作电流，以确保保险丝能够快速切断电流，避免电路过载损坏。

2. 额定电压值（Voltage Rating）：根据电路中的电压需求选择适当的电压额定值。

保险丝的额定电压应略高于电路中的最大工作电压，以确保保险丝能够安全切断电流，并避免电弧和火灾的发生。

3.尺寸和安装方式：根据电路的空间限制和安装需求选择适当的尺寸和安装方式。

自恢复保险丝通常可分为贴片式（SMD）和插件式两种安装方式。

贴片式保险丝适合于紧凑的电路板设计，而插件式保险丝则适用于传统的插件式电路板。

4. 响应时间（Time-to-Trip）：响应时间是指保险丝从开始过载或短路发生到切断电流的时间。

根据系统的要求选择适当的响应时间。

一般来说，响应时间较短的保险丝能够更快地切断电流，但也可能对电路的正常工作造成干扰。

5. 温度特性（Temperature Coefficient）：不同类型的自恢复保险丝的温度特性不同。

根据环境温度和电路工作温度范围选择适当的温度特性。

0805尺寸规格的说明

贴片电阻的功率是指通过电流时由于焦耳热电阻产生的功率。

可根据焦耳定律算出：P=I2 R。

额定功率：是指在某个温度下最大允许使用的功率，通常指环境温度为70°C时的额定功率。

额定电压：可以根据以下公式求出额定电压。

额定电压(V)＝√额定功率(W)× 标称阻值(Ω)最高工作电压：允许加载在贴片电阻两端的最高电压。

贴片电阻的封装与功率、电压关系如下表：图1 (-55 ~+125)功率及环境温度降额曲线图图2 (-55 ~+155)功率及环境温度降额曲线图注意事项：•设计和使用贴片电阻时，最大功率不能超过其额定功率，否则会降低其可靠性。

•一般按额定功率的70%降额设计使用。

•也不能超过其最大工作电压，否则有击穿的危险。

•一般按最高工作电压的75%降额设计使用。

•当环境温度超过70°C，必须按照降额曲线图(图1,图2)降额使用。

我们俗称的封装是指英制。

规格书//电容规格书.pdf贴片电阻常见封装有9种，用两种尺寸代码来表示。

一种尺寸代码是由4位数字表示的EIA(美国电子工业协会)代码，前两位与后两位分别表示电阻的长与宽，以英寸为单位。

我们常说的0603封装就是指英制代码。

另一种是米制代码，也由4位数字表示，其单位为毫米。

一、产品图
二、产品描述
贴片自恢复保险丝（PPTC：高分子自恢复保险丝）是一种正温度系数聚合物热敏电阻，作过流保护用，可代替电流保险丝。

电路正常工作时它的阻值很小（压降很小），当电路出现过流使它温度升高时，阻值急剧增大几个数量级，使电路中的电流减小到安全值以下，从而使后面的电路得到保护，过流消失后自动恢复为低阻值。

其效果与开关元件类似，只是响应速度较慢。

There is apossibility that this can cause exfoliation of the contacts and damage to the optical characteristics of the LEDs. So the moisture proof package is used to keep moisture to a minimum in the package.2、StorageBefore opening the package: The LEDs should be kept at 5~30°C and 60%RH or less. The LEDs should be used within a year.After opening the package: The LED must be used within 24 hours, else should be kept at 5~30℃and 30% RH or less. The LEDs should be used within 7days after opening the package. If unused LEDs remain, they should be stored in moisture proof packages, recommended to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again.If the LEDs have exceeded the storage time, baking treatment should be performed more than 24hours at 60±5°C.3、Soldering IronEach terminal is to the tip of soldering iron temperature less than 300℃ for 3 seconds within once inless than the soldering iron capacity 25 W.Leave two seconds and more internals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.4、RepairingRepairing should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.5、The LED electrode sections are comprised of a gold plated. The gold surface may be affected by environments which contain corrosive gases and so on. Please avoid conditions which may cause the LED to corrode or discolor. This corrosion or discoloration may cause difficulty during soldering operations. It is recommended that the User use the LEDs as soon as possible.6、Please avoid rapid transitions in ambient temperature, especially in high humidity environments where condensation can occur.◆Notes:1、Above specification may be changed without notice. We will reserve authority on material change for above specification.2 、When using this product, please observe the absolute maximum ratings and the instructions for the specification sheets. We assume no responsibility for any damage resulting from use of the product which does not comply with the instructions included in the specification sheets.。

贴片自恢复保险丝测试指南

贴片自恢复保险丝测试指南一：测试流程如下：1. 初始内阻Rimin 测量：拆包装，拿出保险丝，测量保险丝的内阻；2. 焊接：将保险丝通过回流焊焊接在PCB上，PCB上连接有引线，便于进行电性能测试（如上图所示）；3. 保持电流Ihold测试：选用直流恒压恒流源进行测试。

将电压调节到规格书规定的电压Vmax，电流调节到规格书规定的保持电流Ihold，通电15分钟；4. 动作电流Itrip测试：选用直流恒压恒流源进行测试。

将电压调节到规格书规定的电压Vmax，电流调节到规格书规定的保持电流Itrip，通电5分钟；5. R1max测试：将动作后的保险丝放置冷却1小时，测量保险丝的内阻。

二：测试标准：1. 测试环境为25℃的室温环境，无光照、无热辐射；2. 保险丝初始内阻Rimin 需在规格书范围内；3. 保险丝在Ihold电流下保持15分钟不动作，判定为合格；4. 保险丝在Itrip电流下5分钟以内动作，判定为合格；5. 保险丝动作后内阻R1max需在规格书范围内。

三：测试过程中的常见问题附FAQ：Q：实验室只有万用表，可以对内阻进行测量吗？A：推荐使用专业的微电阻测试仪表（如Hioki 3540）进行测量，在没有微阻计的情况下可用万用表作粗略的测量。

Q：实验室没有专业电源设备，用普通的恒压恒流源进行测试可以吗？A：可以用普通的恒压恒流源进行测试。

Q：实验室没有PCB，可以直接放在桌面上进行测试吗？A：保险丝能不能起保护，本质上是保险丝吸收的热量大于释放的热量，保险丝本身的热量不断积累，达到一定程度后保险丝即会起保护。

使用PCB进行测试是对保险丝使用环境的真实摸拟。

若在木质桌面、塑料板、或毛布上面进行测试，因为不同材质的热交换不同，会影响到保险丝热量的释放，从而影响到测试的准确性。

Q：实验室没有SMT设备，可以进行手工焊接吗？A：高分子是自恢复保险丝主要的材料之一。

因高分子受热会影响到其微观状态，进而影响到保险丝的内阻。
