ASMD1206-010 产品概述
一、产品简介
ASMD1206-010 是 JDTfuse（集电通）推出的一款 1206 封装表面贴装自恢复保险（PTC resettable fuse），定位于对低电流线路提供可靠过流保护的场景。器件响应迅速、品质稳定并通过 UL 认证，兼顾性能与成本，适合消费电子、通讯与工业控制等多种场合。
二、主要参数
- 耐压（Vmax）：60 V
- 最大可耐短路电流（Imax）：100 A
- 保持电流（Ihold）：100 mA
- 跳闸电流（Itrip）：250 mA
- 消耗功率（Pd）：400 mW
- 初始态阻值（Rmin）：1.6 Ω
- 跳断后阻值（R1max）：15 Ω
- 动作时间：1 s（典型值）
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装：1206（SMD）
- 认证：UL 认证
三、关键特性与优势
- 精准保护：100 mA 的保持电流与 250 mA 的跳闸电流，使其适合微弱至中等电流负载的过流保护，能有效区分正常工作电流与故障电流。
- 高耐短路能力：器件能承受高达 100 A 的瞬态短路电流，不易因一次冲击损毁，提升系统可靠性。
- 可恢复性：过流后阻值上升到最大 15 Ω，限制电流并在故障消除后自动恢复，无需更换熔断器，便于维护。
- 体积小、易贴装：1206 封装适配主流 SMT 生产线，利于自动化装配与高密度 PCB 设计。
- 工业级温度范围与 UL 认证，满足严格环境与安全要求。
四、典型应用
- USB 及外设保护（接口与充电线路）
- 电池管理与便携设备短路保护
- 网络设备与通信端口过流防护
- 工业控制与传感器前端保护
- LED 驱动与显示模块的安全保护
五、选型与使用建议
- 留有裕量：选择器件时应保证工作电流低于 Ihold，推荐至少留 20%~30% 安全裕量以避免因温升或制造公差造成误动作。
- 考虑涌入电流：对有较大启动电流或突发浪涌的负载，应验证 Itrip 与动作时间是否会频繁触发，必要时选择更大规格或并联方案（并联需谨慎）。
- 布局与散热：尽量靠近电源入口或保护点布置，避免靠近持续发热元件，Pd=400 mW 提示器件长期自热需考虑环境温度对动作特性的影响。
- 焊接建议：按常规 1206 SMD 焊接工艺处理，避免过长高温暴露以保护内部材料特性。
- 测试验证：在目标应用下进行实际温度、浪涌、重复动作等测试，确认长期可靠性与响应行为。
六、可靠性与认证
ASMD1206-010 通过 UL 认证，生产与质量控制符合行业要求，适合要求稳定性与安全性的商用与工业应用。器件在 -40 ℃ 到 +85 ℃ 的工作温度范围内保持性能稳定，适应较为复杂的现场环境。
总结：ASMD1206-010 以其明确的电气参数、良好的自恢复能力和小型封装，适合为低至中等电流电路提供可靠、成本可控的过流保护。根据具体工作电流和环境，合理选型与布局可以充分发挥其保护效果。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
