SMD0805P010TF/24 产品概述

一、产品简介

SMD0805P010TF/24 是 RUILON(瑞隆源)出品的一款微型表面贴装自恢复过流保护器件(PTC resettable fuse),封装为0805(2.2 × 1.5 × 1.0 mm),专为空间受限且工作电流较低的超便携式电子设备设计。器件在过流或短路时自动进入高阻态限流,故障消除后可自动恢复到低阻态,适合对尺寸、重量和可靠性有较高要求的产品。

二、主要性能参数

  • 最大耐压(Vmax):24 V
  • 最大瞬时承受电流(Imax):30 A(短时冲击)
  • 保持电流(Ihold):100 mA(系列化产品保持电流范围可选 0.02 A 至 3.0 A)
  • 跳闸电流(Itrip):300 mA
  • 功耗上限(Pd):500 mW
  • 初始态阻值(Rmin):750 mΩ(0.75 Ω)
  • 跳断后最高阻值(R1max):6 Ω
  • 动作时间:典型 1.5 s(由电流大小和环境温度决定)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:0805(表面贴装)

三、产品特点

  • 小型低矮:0805 封装,适合 PCB 密集布局和便携终端;
  • 自恢复:过流后无需更换器件,设备维护便利;
  • 快速响应:在超过设定跳闸电流时能在短时间内进入高阻态,保护后级电路;
  • 多种保持电流可选:系列覆盖 0.02 A 至 3.0 A,便于针对不同工作电流进行精确选型;
  • 耐脉冲能力:短时冲击电流可达数十安培(典型参数 Imax = 30 A),能承受启动浪涌或瞬态短路;
  • 宽温特性:-40 ℃ 至 +85 ℃,适应多数消费类和工业级便携设备环境。

四、典型应用场景

  • 移动电源、蓝牙耳机、智能手环等超便携移动设备;
  • 便携式传感器、物联网终端、低功耗嵌入式模块;
  • USB/Type-C 的端口过流保护(24 V 以下);
  • 小型充电电路与模块化电源保护。

五、选型与使用建议

  • 选型原则:保持电流(Ihold)应大于器件的最大持续工作电流,常留 20%~30% 余量以避免在正常波动时误动作;跳闸电流(Itrip)要小于电路可允许的过流极限;
  • 温度影响:环境温度越高,保持电流会有所下降,应对高温环境进行适当降额;
  • 浪涌管理:若负载含有大启动电流或频繁冲击,确认 Imax 与脉冲能力是否满足,必要时在前端增加限流或软启动电路;
  • 安全说明:此类自恢复保险适合低压保护,不等同于一次性熔断器,不应用于无法容忍反复过流场合或高压危险回路的主保护。

六、封装与焊接建议

  • 引脚设计与焊盘尺寸遵循0805 参考布局,确保良好热传导与贴合;
  • 推荐采用标准回流焊工艺,遵循供应商给出的回流温度曲线,避免过长高温老化导致性能变化;
  • 推荐在布局上保留适当绝缘间距,并避免将热源紧贴器件以保证稳定动作点。

总结:SMD0805P010TF/24(RUILON)以其微小体积、可选的保持电流范围和自动复位特性,适合对体积和功耗敏感的便携式与嵌入式应用。在设计中正确选型、考虑温度影响与浪涌保护策略,能发挥其最佳保护效果并延长系统可靠性。若需具体电气曲线、回流规范或其它保持电流型号的选型资料,可进一步提供需求以便提供更详细的技术支持。

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
