SMD1210B150TFT — 自恢复保险丝产品概述

一、产品简介

SMD1210B150TFT 为台湾君耀(Brightking)推出的自恢复保险丝(Polyfuse),采用1210贴片封装,专为低压高电流保护设计。器件在过流时自动增阻限流并在故障解除后恢复原有状态,适合现代便携及消费类电子产品中的短路/过流防护需求。

二、主要特性

  • 最高耐压:6V
  • 最大承受电流:100A(短时浪涌或耐受能力)
  • 保持电流(Ihold):1.5A
  • 跳闸电流(Itrip):3A
  • 功耗(Pd):800mW
  • 初始态阻值(Rmin):30mΩ
  • 跳断后最大阻值(R1max):120mΩ
  • 动作时间:约300ms(与过流倍数及环境温度相关)
  • 工作温度范围:-40℃ ~ +85℃
  • 外形尺寸(L×W×H):3.43mm × 2.8mm × 1.07mm
  • 封装:1210,适合表面贴装工艺

三、电气性能解读

保持电流1.5A意味着在此电流及以下,保险丝长期处于低阻态(典型阻值30mΩ),电压降小(例如1.5A时约45mV)。当电流上升并达到或超过3A时器件在典型条件下会在约300ms内显著增阻以限制电流,跳断后阻值可达120mΩ,起到保护作用。Pd=800mW提示在高功耗工况需考虑器件及周边散热。

四、典型应用

  • USB/充电线路、移动电源保护
  • 锂电池及电池管理系统(BMS)短路保护
  • 龙头消费电子(智能手机、平板、笔记本电源输入)
  • 通信设备、路由器、电源模块和工业控制的小电流过流保护
  • 电机驱动、继电器线圈等存在突发浪涌的场合(作为配合保护元件)

五、使用建议与注意事项

  • 选型时应根据工作电流、最大容许电压及环境温度进行适当余量设计,避免长期在Ihold附近工作导致过热漂移。
  • Imax=100A为瞬态耐受能力并非连续工作值,请勿作为常态电流设计依托。
  • 动作时间受环境散热、PCB板厚及铜箔面积影响,布局时应考虑散热通道与铜皮面积以保证稳定触发特性。
  • 建议遵循制造商回流焊工艺指南进行贴装,避免超温或长时间暴露在高温环境中影响可靠性。
  • 对于关键安全应用,应配合过压、限流等多重保护策略使用。

六、封装与采购信息

产品型号:SMD1210B150TFT
品牌:Brightking(台湾君耀)
封装:1210 SMD,适合自动贴装与回流焊流程。具体贴片焊盘和回流参数请参考厂商Datasheet或向供应商索取推荐焊盘图与工艺说明。

总结:SMD1210B150TFT以小体积、低初始阻抗和可靠的自恢复特性,为5V及以下高电流场合提供经济且可重复的保护方案。在设计与布局阶段务必考虑散热与触发裕度,以确保长期稳定运行。若需更详细的测试曲线或封装数据,可联系Brightking获取完整资料。

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
