SMD1206P075TF/30 产品概述

一、产品简介

SMD1206P075TF/30 是 RUILON(瑞隆源)推出的一款微型表面贴装过流保护器件,采用 1206 封装,适用于空间受限的现代电子产品。该系列提供保持电流范围从 0.05A 到 4.5A 的多种型号,此型号的典型保持电流为 0.75A(Ihold),跳闸电流为 1.5A(Itrip),为低压直流电源线路提供可靠的自动复位保护。

二、主要参数

  • 额定耐压(Vmax):30V
  • 最大允许电流(Imax):8A
  • 保持电流(Ihold):0.75A
  • 跳闸电流(Itrip):1.5A
  • 功耗(Pd):600mW
  • 初始态阻值(Rmin):90 mΩ
  • 跳断后阻值(R1max):500 mΩ
  • 动作时间:35 s(在指定过流条件下)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:1206(SMD)
  • 品牌:RUILON(瑞隆源)

三、主要特点与优势

  • 体积小,适配 1206 标准贴片工艺,便于自动化贴装与回流焊;
  • 初始阻值低(90 mΩ 起),降低正常工作下的压降与功耗;
  • 自动复位特性:过流解除后可恢复导通,适合反复保护场景;
  • 跳断后阻值上升(≤500 mΩ),能有效限制故障电流;
  • 宽工作温度范围,适应工业级温度要求;
  • 额定耐压 30V,覆盖常见 USB、通信与小功率电源应用。

四、典型应用场景

  • 移动设备与便携式电子产品的输入电源保护;
  • USB、Type-C 接口、电源适配器前端保护;
  • 物联网节点、智能家居模块、电池管理外围保护;
  • 工业控制与通信设备的局部电路过流防护;
  • 电源分配板及模块化电源系统的支路保护。

五、设计与布局建议

  • 放置位置:建议置于电源输入或子供电支路的第一颗保护器件,靠近连接器以限制故障电流路径;
  • 热管理:Pd = 600 mW,长期通过接近 Ihold 电流时需重视 PCB 散热与铜箔面积,以避免过热误动作;
  • 焊接工艺:遵循制造商回流焊曲线,避免长时间高温暴露;1206 封装兼容常见回流工艺,但建议按元件包装说明处理防潮要求;
  • 电路配合:对于含有大电容或感性负载的电路,可在前端同时配合瞬态抑制器(TVS)或限流元件,以应对冲击电流。

六、选型要点与替代方案

  • 若系统允许更高持续电流或需要更低压降,可选择保持电流更高的同系列型号或更大封装(如 2012/2512);
  • 对于一次性熔断保护使用熔丝而非可复位器件;若需极低内阻和更快动作,选择快熔或电子断路器件。

七、存储与可靠性注意

  • 建议密封干燥保存,避免长期潮湿环境;
  • 在贴装前遵循防潮封装规范,必要时进行回流前回潮烘烤;
  • 在高振动或机械冲击场合注意固定与机械缓冲设计。

结语:SMD1206P075TF/30 在 1206 小封装中实现了较好的低压降与可复位过流保护,适合对体积、成本和可靠性有综合要求的现代电子设备。如需详细电气特性曲线、时间—电流特性或回流焊推荐曲线,请参考 RUILON 官方数据手册或联系供应商获取完整资料。

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
