ASMD1206-005 产品概述

一. 概述

ASMD1206-005 是 JDTfuse(集电通)推出的一款 1206 封装自恢复式过流保护器件(PPTC),专为小体积电子产品提供可靠、可重复的过流和短路保护。器件通过 UL 认证,品质稳定,性价比高,适用于对尺寸和成本有较高要求的消费电子、通讯与工业控制领域。

二. 主要电气参数

  • 最高耐压(Vmax):60 V
  • 最大承受电流(Imax):100 A(瞬态或短时能力)
  • 保持电流(Ihold):50 mA(在规定环境条件下保持闭合状态的最大稳态电流)
  • 跳闸电流(Itrip):150 mA(在该电流下器件将进入高阻限流状态)
  • 最大功耗(Pd):400 mW(在特定测试条件下的功耗上限)
  • 初始态阻值(Rmin):3.6 Ω(冷态初始电阻)
  • 跳断后阻值上限(R1max):50 Ω(进入保护态后的最大阻值)
  • 动作时间:约 1.5 s(在标准过流测试条件下测得的典型动作时间)

以上参数为器件在规范测试条件下的标称值,实际应用时需参考具体工作环境与电路条件。

三. 机械与环境规格

  • 封装:1206 SMD(适合表面贴装工艺)
  • 外形尺寸:长度 3.6 mm × 宽度 1.9 mm × 高度 1.2 mm
  • 工作温度范围:-40 ℃ ~ +85 ℃

紧凑的 1206 封装便于在有限空间内进行布局,适配标准回流焊工艺,便于自动化贴装与生产。

四. 特点与优势

  • 小尺寸、高集成度:1206 封装适合空间受限的电路板设计。
  • 可重复保护:自恢复结构在故障解除后自动恢复,降低维护成本。
  • 快速响应:在规定过流条件下动作时间约 1.5 s,能有效限制短路能量传递。
  • 宽温度适应性:-40 ℃ 至 +85 ℃ 的工作区间满足工业级和消费级应用。
  • 可靠认证:通过 UL 认证,符合国际安全标准,质量可追溯。
  • 成本效益高:JDTfuse 品牌定位注重性价比,适合量产项目使用。

五. 典型应用场景

  • USB 及外围接口保护(数据线/供电线)
  • 小功率电源管理与保护模块
  • 电池充放电保护与过流防护(便携设备)
  • 物联网终端、智能家居与消费电子产品保护
  • LED 驱动与照明电路(低电流分支)
  • 通信设备的小电流分路保护

六. 选型与使用建议

  • 确认 Ihold 与 Itrip:保持电流 50 mA、跳闸电流 150 mA,选择时以电路常态电流低于 Ihold 为准,短时浪涌不得长时间高于 Itrip。
  • 考虑环境与散热:在高温环境中器件触发特性会改变,需适当留有裕量。
  • 考虑浪涌与峰值:Imax 标明器件可承受的瞬时高电流能力,适用于短时浪涌,但应避免频繁接近该值。
  • PCB 布局:保证焊点与铜箔散热合理,避免局部过热影响器件性能与寿命。
  • 测试与验证:在实际系统中做温升、动作时间和恢复测试,确保在目标工况下表现符合预期。

七. 质量与包装

ASMD1206-005 由 JDTfuse(集电通)生产,已通过 UL 认证,适用于对安全与可靠性有明确要求的量产项目。标准 1206 卷带/盘装方式,兼容自动贴片生产线,具体包装规格与最小起订量可与供应商确认。

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
