ASMD0603-050 产品概述
一、产品简介
ASMD0603-050 是 JDTfuse（集电通）推出的一款微型自恢复保险丝（PTC resettable fuse），封装为标准 0603（长 1.6mm × 宽 0.8mm × 高 1.1mm）。该器件针对便携与空间受限的电子设备设计，具有耐压 6V、最大通过电流 40A 的瞬态耐受能力，并提供稳定的过流保护与自恢复功能。产品通过 UL 认证，品质可靠且性价比高，适用于消费电子、通信、车载辅助电路与工业控制等场景。
二、主要电气参数
- 额定耐压 (Vmax)：6V
- 最大电流 (Imax)：40A（瞬态承受能力）
- 保持电流 (Ihold)：500mA（在规定温升下，长期不动作的最大电流）
- 跳闸电流 (Itrip)：1A（在规定时间内动作）
- 消耗功率 (Pd)：500mW（最大稳态功耗）
- 初始态阻值 (Rmin)：100mΩ
- 跳断后阻值 (R1max)：800mΩ
- 动作时间：100ms（典型）
- 工作温度范围：-40℃ ~ +85℃
三、结构与封装
ASMD0603-050 采用 0603 标准封装，尺寸为 1.6 × 0.8 × 1.1 mm，便于在高密度 PCB 上布置。薄型、小尺寸设计利于自动贴装与回流焊工艺，适配常见 SMT 生产线。
四、性能与优势
- UL 认证，符合安全与可靠性要求，便于产品取得下游认证。
- 自恢复特性：在过流解除后自动恢复导通，免维护，降低售后成本。
- 高瞬态耐受能力（Imax 40A）：能承受启动浪涌或短时冲击电流，保护后端电路。
- 低初始阻值（≥100mΩ）与可控跳断后阻值（≤800mΩ），在保护状态与正常工作间切换稳定可控。
- 宽温工作范围（-40℃ ~ +85℃），适应多种环境。
五、典型应用场景
- USB/外设供电保护（移动电源、充电器）
- 摄影机、手机、平板等便携式产品的电源保护
- IoT 终端、智能家居与可穿戴设备的电源管理
- 工业控制与车载电子的局部过流防护（非主电路）
六、选型与使用建议
- 确认系统的最大工作电流与瞬态浪涌特性，保持 Ihold 与实际工作电流有适度裕量，避免误动作。
- 评估环境温度与散热条件，高温会降低器件的 Ihold 值，应适当降额使用。
- 布局时建议靠近被保护的电源入口处放置，保证快速检测与动作。
- 使用标准 0603 封装焊盘并遵循厂家推荐回流曲线，避免过热或机械应力导致可靠性下降。
七、可靠性与质量控制
JDTfuse（集电通）对材料与制造流程严格把关，产品通过 UL 认证并经过温度循环、老化与过流耐久性测试。标准包装与批次追溯保证批量一致性，适合量产应用。
如需更详细的温升曲线、I–V 特性曲线或回流焊工艺建议，请提供具体应用工况或索取产品数据手册（Datasheet）。

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.
