SMD2920P200TF 产品概述

一、产品简介

SMD2920P200TF 是 RUILON(瑞隆源)推出的一款 2920 封装自恢复(聚合物 PTC)过流保护器件,额定耐压 16V,保持电流(Ihold)2A,跳闸电流(Itrip)4A。器件在短路或过流时通过电阻迅速上升限制电流,故障解除并冷却后可自动恢复导通,适用于多种板级过流保护场合。

二、主要电气与热特性

  • 耐压(Vmax):16V(适用于 5V、12V 等低压直流系统)
  • 最大冲击电流(Imax):40A(瞬态冲击承受能力)
  • 保持电流(Ihold):2A(长期不触发时允许的最大电流)
  • 跳闸电流(Itrip):4A(在规定时间内开始进入限制状态)
  • 消耗功率(Pd):1.5W(热耗散能力参考)
  • 初始态阻值(Rmin):20mΩ;跳断后阻值(R1max):120mΩ
  • 动作时间:4.5s(从过流到进入高阻态的典型时间)
  • 工作温度范围:-40℃ ~ +85℃

三、机械尺寸与封装

器件为 2920 SMD 封装,尺寸为 7.98mm × 5.44mm × 1.4mm,适合自动贴片与回流焊工艺。紧凑外形便于在空间受限的电路板上进行电源入口或接口处布局。

四、应用场景

SMD2920P200TF 适合以下典型应用:

  • USB、OTG、电源口的过流保护;
  • 车载电子(12V 子系统)与电池供电设备的短路保护(需注意系统电压与热环境);
  • 家电、便携式设备与手持终端的电源防护;
  • 通信设备与工业控制模块的板级保护。
    在选择时建议根据实际工作温度、环境散热条件及峰值浪涌特性进行适当裕量设计。

五、设计与使用建议

  • 建议将器件靠近电源入口或受保护端口布局,以提高保护效果并便于热量散发;
  • 在高热或封装密集区使用时,应考虑外部散热与周围器件的热耦合,避免误动作;
  • 对于需频繁承受大冲击电流的场合,应评估器件寿命与恢复特性并适当选型;
  • 支持标准 SMT 回流焊但应遵循制造商的回流温度曲线与焊接工艺规范以保证可靠性。

六、可靠性与采购信息

器件设计性能在 -40℃ 至 +85℃ 下稳定,适应一般工业级应用环境。品牌:RUILON(瑞隆源),封装:2920,型号:SMD2920P200TF。常用于自动贴片生产线,采购时请确认批次与出厂检测报告以确保参数一致性。

若需更详细的电气曲线、热阻参数或回流曲线,建议向供应商索取完整数据手册与可靠性测试报告以便在具体电路中准确仿真与验证。

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
