SMD0805P110TF 自恢复保险丝产品概述

一、产品基本信息

SMD0805P110TF是RUILON(瑞隆源) 推出的0805封装自恢复过流保护器件,属于聚合物正温度系数(PPTC)保险丝类别。其核心价值是在电路过流时快速切断电流保护后端元件,故障排除后自动恢复导通,无需人工更换,是低压小功率电路的高效保护方案。

二、核心电气参数详解

该产品的参数直接决定其保护性能与适用场景,关键指标如下:

  1. 耐压(Vmax):6V
    最大允许工作电压,电路正常电压需低于此值,超压可能导致绝缘失效。
  2. 最大浪涌电流(Imax):35A
    可耐受的瞬间最大电流(如静电、瞬时短路),超此值可能永久熔断。
  3. 保持电流(Ihold):1.1A
    正常工作时电流不超过1.1A则保持低阻导通,不影响电路运行。
  4. 跳闸电流(Itrip):2.2A
    电流超2.2A时,保险丝在动作时间内跳断,阻断过流。
  5. 消耗功率(Pd):600mW
    正常工作时的功率损耗,低功耗设计不影响电路能效。
  6. 初始态阻值(Rmin):35mΩ
    故障前最小导通电阻,低阻可减少信号损耗与电压降。
  7. 跳断后阻值(R1max):210mΩ
    过流后最大电阻,有效限制故障电流,保护后端器件。
  8. 动作时间:300ms
    从电流达跳闸阈值到完全跳断的时间,响应及时,避免器件损坏。

三、封装与物理特性

采用标准0805贴片封装,尺寸为2.0mm(长)×1.2mm(宽)×0.8mm(厚),符合IPC国际标准,具备以下特点:

  • 兼容SMT自动化生产,效率高;
  • 小型化设计,适配高密度PCB布局,满足设备轻薄化需求;
  • 引脚镀锡/镀金,焊接兼容性好,无铅环保(符合RoHS 2.0)。

四、典型应用场景

因低电压(6V)、小电流(1.1A保持)特性,广泛用于:

  1. 便携式电子:智能手机、智能手表、蓝牙耳机的单节锂电池保护;
  2. 小型数码:MP3、移动电源、电子词典的电源回路保护;
  3. 物联网终端:低功耗传感器、智能手环、智能家居模块的电路保护;
  4. USB接口:USB 2.0/3.0接口的过流保护(5V供电符合耐压要求);
  5. 低压工业:小型PLC、传感器模块的辅助电源保护。

五、产品优势与特点

  1. 自恢复功能:故障排除后自动导通,无需更换,降低维护成本;
  2. 低阻导通:初始35mΩ阻值,信号损耗极小,不干扰电路;
  3. 快速响应:300ms动作时间,快速阻断过流,保护敏感元件(如IC、显示屏);
  4. 宽温适应:-40℃~+85℃工作范围,适配户外、工业等不同环境;
  5. 小型化:0805封装适合高密度PCB,满足设备轻薄化趋势;
  6. 环保合规:无铅无卤,符合RoHS、REACH标准,适合出口产品。

六、使用注意事项

  1. 电压限制:工作电压不得超6V,避免绝缘击穿;
  2. 浪涌耐受:瞬间浪涌不超35A,防止永久熔断;
  3. 焊接工艺:回流焊遵循IPC温度曲线(峰值230℃~250℃,时间≤10s),避免高温损坏;
  4. 故障恢复:故障排除后,待温度降至室温(≈25℃),阻值自动恢复后再工作;
  5. 极性无要求:自恢复保险丝无极性,安装无需区分正负极。

SMD0805P110TF凭借自恢复、低阻、小型化等优势,成为低压小功率电路过流保护的优选器件,可有效提升电子设备的可靠性与安全性。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
