SMD1206P016TF 产品概述

一、产品简介

SMD1206P016TF 是一款 1206 封装的自恢复熔断器(Polyfuse/PTC),由 RUILON(瑞隆源)提供。器件用于电路过流与短路保护,正常工作时阻值低,出现过流时通过自身发热使阻值迅速上升以限制电流,故障消除后随温度恢复而自动复位,无需更换,适合表面贴装工艺的紧凑型保护设计。备注:样本信息中耐压项存在标注差异(16V 与 30V),实际应用时以厂家最新规格书为准。

二、主要技术参数

  • 标称耐压(Vmax):16V(请核对厂家资料)
  • 最大电流(Imax):10A
  • 保持电流(Ihold):160mA
  • 跳闸电流(Itrip):370mA
  • 功耗(Pd):400mW
  • 初始态典型阻值(Rmin):1Ω
  • 跳断后最大阻值(R1max):10Ω
  • 动作时间:约 300ms(受环境与电流波形影响)
  • 工作温度:-40℃ ~ +85℃
  • 外形尺寸:长 3.6mm × 宽 1.9mm × 高 1.0mm
  • 封装:1206,表面贴装

三、工作原理与性能特点

该器件基于聚合物正温度系数材料,在正常电流下呈低阻抗通路,电路发生过流时器件升温,材料电阻急剧上升,从而限制电流并保护下游电路。故障消除后随器件冷却电阻恢复,完成自恢复功能。主要特点包括:响应快、可多次复位、体积小、易于 SMD 贴片组装、对瞬态过流有良好抑制能力。需要注意的是,跳断后阻值可能增加到数欧姆至十欧姆量级,会造成电压降,且长期处于高温或频繁触发会影响寿命与热特性。

四、典型应用场景

  • USB 接口与外设保护(数据线、充电口等)
  • 便携式设备与移动电源的输入保护
  • 电池组与充电管理线路的过流保护
  • LED 驱动与照明电源保护
  • 通信设备、工控及仪表的局部电路保护

五、选型与使用建议

  • 选型时将 Ihold 设定为正常工作最大发电电流的 1.1–1.5 倍,以避免误动作;Itrip 与最大短路电流水平应满足保护需求。
  • 关注器件额定电压,应以实际工作电压留有裕量;若样本中出现 16V 与 30V 不一致,务必以厂家数据和实物标识为准。
  • 布局时注意器件周围散热与热耦合,避免热累积引发误动作;贴片回流焊需遵循厂家推荐温度曲线。
  • 若电路对电压降敏感,应评估跳断后阻值对系统影响,必要时考虑并联或改用更高规格保护元件。

如需用于特定电路,请提供工作电压、最大工作电流与环境温度等信息,以便进行更精确的选型与匹配建议。

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
