ASMD0805-100自恢复保险丝产品概述

一、产品定位与品牌简介

ASMD0805-100是JDTfuse(集电通) 品牌推出的贴片式自恢复保险丝,专为小型化、低电压电路的过流保护需求设计。作为集电通旗下主流防护器件,该产品依托品牌在过流保护领域的技术积累,兼顾小封装、快速响应与自恢复特性,适配各类紧凑电子设备的防护场景,是替代传统一次性保险丝的高效解决方案。

二、核心参数详细解析

ASMD0805-100的参数明确了其适用范围与性能边界,关键指标如下:

2.1 电气基础参数

  • 电压能力:最大工作电压6V,适配低电压直流/交流电路(如电池供电系统、小型家电);
  • 电流特性:
    • 保持电流(Hold Current)1A(电路正常工作时可稳定导通的最大电流);
    • 跳闸电流(Trip Current)1.95A(过流触发动作的最小电流,确保过流时及时切断);
    • 峰值耐受电流100A(短时间冲击电流耐受能力,应对突发浪涌);
  • 电阻特性:
    • 初始态阻值最小60mΩ(导通损耗低,不影响电路正常信号传输);
    • 跳断后阻值最大230mΩ(故障时有效阻断电流,故障排除后恢复低阻)。

2.2 时间与功率参数

  • 动作时间:最大动作时间300ms(过流触发后快速切断,保护后端敏感器件如芯片、电池);
  • 消耗功率:额定消耗功率600mW(正常工作时的功率损耗,需匹配电路散热设计)。

2.3 环境与封装参数

  • 工作温度:-40℃~+85℃(宽温范围,适应户外、车载等极端温度场景);
  • 封装形式:0805贴片封装(尺寸约2.0mm×1.25mm,适配高密度PCB布局)。

三、封装特性与适配场景

0805封装是ASMD0805-100的核心设计亮点:

  • 小型化优势:尺寸紧凑,可集成于智能手机、智能手表等便携设备的微小PCB中,不占用额外空间;
  • 贴片工艺适配:兼容常规SMT贴片工艺,适合自动化生产,降低组装成本;
  • 高集成度场景:适配多器件密集布局的电路(如传感器模块、无线充电电路),满足小型化产品的防护需求。

四、性能优势总结

相比传统一次性保险丝,ASMD0805-100具备明显应用优势:

  1. 自恢复免维护:故障排除后自动恢复导通,无需人工更换,降低维护成本与停机时间;
  2. 低损耗导通:最小60mΩ初始电阻,导通时功率损耗小,不影响电路效率;
  3. 快速响应防护:300ms内快速动作,有效避免过流对后端器件的不可逆损坏;
  4. 宽温稳定工作:-40℃~+85℃温度范围,适应车载低温、户外高温等极端环境;
  5. 峰值电流耐受:100A峰值电流能力,可应对突发冲击(如静电放电、瞬间浪涌)。

五、典型应用领域

该产品主要应用于以下场景:

  • 便携电子:智能手机电池保护、智能手表充电电路、无线耳机防护;
  • 小型家电与传感器:遥控器电源防护、温湿度传感器模块、小型智能家居设备;
  • 汽车电子:车载仪表盘背光电路、胎压监测传感器防护、车载USB充电口;
  • 通信与消费电子:小型基站模块、蓝牙音箱、移动电源的过流保护。

六、使用注意事项

为确保性能稳定,需注意以下要点:

  1. 参数匹配:电路工作电压不超过6V,正常电流不超过1A,避免超参数使用;
  2. 散热设计:额定功率600mW,需合理布局PCB散热铜箔,避免局部过热影响动作特性;
  3. 动作次数限制:自恢复保险丝存在动作寿命(一般数千次),频繁过流可能导致性能衰减;
  4. 焊接规范:0805封装焊接温度需控制在260℃以下,焊接时间不超过3秒,避免热损坏。

ASMD0805-100凭借小封装、自恢复、宽温等特性,成为小型低电压电路过流保护的高性价比选择,可有效提升设备可靠性与用户体验。

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
