SMD0603-100/06N 产品概述

一、简介

SMD0603-100/06N 是 BORN(伯恩半导体)推出的一款微型自恢复保险(Polyfuse/PTC),采用标准 0603 贴片封装(长 1.85mm × 宽 1.05mm × 高 1.15mm)。器件面向空间受限的便携和消费类电子电源保护,提供快速过流保护与故障自恢复能力,适用于电缆、接口与电池保护等场合。

二、主要性能与参数

  • 额定耐压:Vmax = 6V
  • 最大持续电流:Imax = 35A
  • 保持电流:Ihold = 1A
  • 跳闸电流:Itrip = 2A
  • 功耗(稳态):Pd = 500mW
  • 初始态电阻:Rmin = 50mΩ
  • 跳断后最大电阻:R1max = 300mΩ
  • 动作时间(至跳闸):≈100ms
  • 工作温度范围:-40℃ ~ +85℃

这些参数表明该型号在低压、小电流保护中响应迅速,且在超过阈值后能在约 100ms 内进入高阻态以限制电流,恢复后可继续工作,适合对体积要求严格的设计。

三、产品特点

  • 极小封装(0603),便于高密度贴装与自动化生产
  • 快速动作:约 100ms 跳闸,保护敏感器件免受短路冲击
  • 可复位设计,降低维护与更换成本
  • 低初始电阻(50mΩ),对正常工作电流的压降小
  • 跳断后电阻≤300mΩ,有效抑制过流电平

四、典型应用

  • USB/数据接口过流保护(移动电源、充电器)
  • 便携式设备与穿戴电子电源管理
  • 电池包与电源线短路保护
  • 工业控制与测量仪器的局部防护

五、设计与使用建议

  • 选择时预留安全裕度:建议工作电流远低于 Ihold,并使短路电流与器件 Itrip 匹配以保证可靠动作。
  • 热管理:Pd=500mW 表明在高环境温度或密集布局下器件发热不可忽视,避免与高热源紧邻。
  • 焊接与贴装:兼容常规回流工艺,推荐按厂家回流曲线控制温度与时间以保证性能稳定。
  • 测试与验证:在目标环境(温度、周边热源、电源瞬态)下验证动作时间与恢复特性。
  • 替换与维护:自恢复但在多次严重过流后可能性能衰退,建议在关键应用中制定检测或替换周期。

SMD0603-100/06N 以其微型化与可靠的自恢复过流保护特性,适合对尺寸和成本敏感的现代电子产品,是常见的短路/过流防护元件选择。

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
