SMD1210P020TF 产品概述 — RUILON(瑞隆源)

SMD1210P020TF 为 RUILON(瑞隆源)推出的一款 1210 封装表面贴装自恢复保险元件(PPTC),适用于对过流、短路保护有快速响应与可复位要求的小型电子设备。产品已通过校验,参数稳定可靠,适配批量贴装生产与自动化装配线。

一、主要技术参数

  • 耐压(Vmax):30V
  • 最大电流(Imax):30A(短时承受能力)
  • 保持电流(Ihold):200mA
  • 跳闸电流(Itrip):400mA
  • 消耗功率(Pd):600mW
  • 初始态阻值(Rmin):400mΩ
  • 跳断后阻值(R1max):≤5Ω
  • 动作时间:20ms
  • 工作温度:-40℃ ~ +85℃
  • 尺寸(L×W×H):3.5mm × 2.8mm × 1.1mm
  • 封装:1210,表面贴装(SMD)

二、产品特性

  • 响应快速:20ms 的动作时间可在短时间内切断异常过流,保护下游器件。
  • 可复位:发生过流跳闸后,断开电流解除即可自动恢复,减少维护与更换成本。
  • 低初始阻值:典型初始阻值 400mΩ,保证正常工作时压降与功耗较低。
  • 跳断后高阻态:跳断后阻值可达 ≤5Ω,确保有效限制后续故障电流。
  • 宽温区工作:-40℃ 至 +85℃,适应户内、车载、工业等多种环境。

三、典型应用场景

  • 消费电子:便携设备、充电器、移动电源等的输入和输出保护。
  • 通信设备:路由器、交换机、基站模块的电源保护。
  • 工业设备:传感器模块、驱动电路的短路与过流保护。
  • 汽车电子(辅助电路):车载信息娱乐、辅助电源保护(应按车规要求评估)。

四、选型与使用建议

  • 根据回路工作电流选择:Ihold(200mA)应高于正常工作电流,Itrip(400mA)应低于可接受的故障电流水平。
  • 考虑峰值与短时冲击:器件 Imax 为短时承受能力(30A),并非长期连续电流值,应用时应避免长时过载。
  • 热管理:尽管工作温度范围宽,但高功率、紧凑布局会增加自热,应考虑周边散热条件以保持可靠性。
  • 系统验证:在目标系统中验证动作时间与恢复行为,确认跳闸后系统状态与需求相适配。

五、封装与装配注意

  • 封装为 1210 SMD,可直接用于回流贴装生产线。
  • 建议遵循主流无铅回流焊工艺与厂商推荐的焊接曲线,避免过高温度或超时焊接以免影响性能。
  • 贴装设计时注意焊盘尺寸与过孔布局,确保良好焊接与热传导。

六、储存、可靠性与安全提示

  • 储存避免高温高湿环境,建议按元件标准防潮包装存放与使用。
  • 若用于关键安全系统或车规应用,建议做额外的环境应力测试与长时间老化验证。
  • 跳闸为保护动作,频繁重复跳闸可能影响器件寿命,应查找并消除根本故障原因。

结语:SMD1210P020TF 以小型 1210 封装、快速动作与可复位特性,适合对电路过流保护有严格空间与可靠性要求的场合。选型与应用时请结合实际工作电流、热条件与系统容错策略进行综合评估。若需详细电气图或样品测试报告,可联系 RUILON(瑞隆源)或授权代理获取。

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
