ASMD0603-010-30V 产品概述

一、产品简介

ASMD0603-010-30V 为 JDTfuse(集电通)推出的一款微型自恢复过流保护器件,封装尺寸为业界通用的 0603(1.6 × 0.8 × 1.0 mm)。器件以稳定的品质与较高的性价比为设计目标,适用于空间受限的便携、通信和消费类电子产品电源保护场景。其工作电压上限为 30V,可在较宽的温度范围(-40℃…+85℃)内可靠工作,响应速度适合对中低幅度持续过流进行保护与自恢复。

二、主要规格参数

  • 型号:ASMD0603-010-30V(JDTfuse / 集电通)
  • 封装:0603(尺寸:1.6 mm × 0.8 mm × 1.0 mm)
  • 最高工作电压(Vmax):30 V
  • 峰值承受电流(Imax):40 A
  • 保持电流(Ihold):100 mA
  • 跳闸电流(Itrip):300 mA
  • 功耗(Pd):500 mW(额定功耗)
  • 初始态等效电阻(Rmin):900 mΩ(0.9 Ω)
  • 跳断后最大电阻(R1max):6 Ω
  • 动作时间(从正常到触发):约 1 s(在标准测试条件下)
  • 工作温度范围:-40 ℃ ~ +85 ℃

注:上述参数为器件典型/额定值,具体应用中性能可能受环境温度、散热条件及测试方法影响,选型时建议参考厂方详细电气-热特性曲线与应用说明。

三、特点与优势

  • 小尺寸高集成:0603 封装,适配高密度贴片 PCB,节省空间。
  • 自恢复保护:过流触发后器件阻值升高限流并保护下游电路,故障消除后自动恢复,降低维修成本。
  • 低初阻:初始态典型 0.9 Ω,有利于减小压降与功率损耗,保证正常工作时系统效率。
  • 快速响应:约 1 秒动作时间,可有效应对恒态或中等速率的过流事件。
  • 宽温度范围:-40℃ 至 +85℃,适应多种工业与民用环境。
  • 性价比高:JDTfuse 品牌在中小电流自恢复保险丝市场具有良好成本控制与可靠性表现。

四、典型应用场景

  • USB、移动电源与充电口的短路/过流保护;
  • IoT 终端、便携式消费电子的输入电源保护;
  • 电池管理与保护电路中对支路过流的防护;
  • 低压 DC-DC 模块、电源滤波前的预保护;
  • 其他空间受限但需重复自恢复保护的场景。

五、设计与使用建议

  • 布局:建议将器件尽量靠近电源入口或被保护的电源引脚放置,以减少保护回路的寄生电感与电阻,提升保护效果。
  • 散热:器件的动作与恢复受周围 PCB 散热条件影响较大,热量易散失的情况下触发电流可能上移;若环境温度偏高,应适当放宽工作电流裕度。
  • 并联/串联:一般不建议将同型号器件并联使用以分享电流(并联分流不均导致保护失效);若需要更大电流处理能力,优先选用额定电流更高的型号。
  • 验证测试:在目标产品的工作环境和最大工作电流条件下进行实测验证,包括过流触发、恢复时间及耐久性循环测试。
  • 焊接兼容性:兼容常见 SMT 回流焊工艺,适合自动贴装。建议在产品试制阶段与组装厂确认回流曲线对器件性能的影响。

六、可靠性与质量控制

ASMD0603-010-30V 设计用于满足消费与工业级应用的可靠性需求,工作温度范围与多次自恢复能力使其在重复过流环境下表现稳定。出厂时通常经过电气参数筛选与外观检测。对于批量项目,可与供应方沟通额外的测试报告(如温度循环、耐久性试验)以满足特殊可靠性要求。

七、包装与采购提示

  • 封装形式为 0603 SMT,常见为卷带(Tape & Reel)适配自动贴装;具体包装数量与盘带规格请向供应商确认。
  • 采购时请确认器件完整型号 ASMD0603-010-30V 及所需数量,必要时索要样品进行实机验证,避免因版本或出厂批次差异影响量产。

总结:ASMD0603-010-30V 是一款体积非常小、针对中小电流场景的自恢复过流保护器件,适合对体积、成本、自动化贴装有严格要求的电子产品。合理的电路布局与热管理可确保其在实际应用中发挥最佳保护效果。若需进一步电气曲线、热特性或样品支持,可联系 JDTfuse(集电通)或授权分销商获取详细资料。

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.
