SMD0805P035TF 产品概述

一、产品简介

SMD0805P035TF 是 RUILON(瑞隆源)出品的一款0805封装自恢复保险丝(PTC复位式热敏保护器件),适用于低电压、低电流的电子保护场合。器件额定耐压为6V,具有可多次自恢复的过流保护能力,当异常电流发生时能快速限流并在故障消除后自动恢复,便于重复使用和维护。

二、主要参数

  • 耐压(Vmax):6V
  • 最大电流(Imax):30A(瞬时峰值能力)
  • 保持电流(Ihold):350mA(正常工作不动作)
  • 跳闸电流(Itrip):750mA(典型动作电流)
  • 消耗功率(Pd):500mW
  • 初始态阻值(Rmin):200mΩ
  • 跳断后阻值(R1max):1.2Ω
  • 动作时间:约100ms(在达到 Itrip 时的典型动作响应)
  • 工作温度:-40℃ ~ +85℃
  • 尺寸(L×W×H):2.2mm × 1.5mm × 1.0mm(0805封装)

三、产品特点

  • 小型0805封装,便于高度密集的表贴装配和自动化生产。
  • 低初始阻值,能在正常工作下保持较低功耗与电压降。
  • 快速动作(约100ms),在短时间内限制过流以保护下游元件。
  • 自恢复型设计,故障消除后自动恢复导通,降低维修复杂度与维护成本。
  • 宽工作温度范围,适应多种环境条件。

四、典型应用

  • 移动电源、便携式设备的输入/输出短路保护
  • USB、充电口、电源总线过流保护
  • 电池管理系统(BMS)与电源模块的局部保护
  • 电子玩具、家用小电器及工业控制板的过流防护

五、选型与使用建议

  • 在选型时应保证器件的保持电流 Ihold 大于电路的最大正常工作电流,避免误动作。
  • 跳闸电流 Itrip 应低于被保护电路或元件可承受的危险电流值,从而实现有效保护。
  • 对可能出现的短时冲击电流(如瞬态浪涌)请关注器件的 Imax 能力及实际能承受的脉冲特性,必要时配合滤波或浪涌吸收器件使用。
  • 布局时尽量将保护器件靠近电源入口处,减少线缆或走线的暴露,保证热量能及时散发以利于自恢复。

六、安装与可靠性注意

  • 建议采用标准回流焊工艺贴装,避免长时间高温暴露超出回流规范。
  • 摆放时尽量远离高功率热源,避免在高温环境下长期接近额定上限。
  • 出货前按实际工况进行样机测试,验证在目标温度和电流条件下的动作与恢复特性。

Sourcing availability signal

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
