ASMD1206-050自恢复保险丝产品概述

ASMD1206-050是JDTfuse(集电通)推出的一款1206贴片封装自恢复保险丝,专为低电压、高密度电路的过流保护场景设计,兼顾小体积、低损耗与快速响应特性,可满足消费电子、便携设备及小型工业电路的可靠性防护需求。

一、品牌与产品定位

JDTfuse(集电通)作为国内专注于过流保护器件的品牌,其ASMD系列贴片自恢复保险丝针对小尺寸应用场景优化。ASMD1206-050定位于低电压(6V以下)电路的低成本、免维护过流保护,区别于传统一次性保险丝,可在故障排除后自动恢复导通,无需人工更换,大幅降低后期维护成本与设备 downtime。

二、核心基础参数解析

ASMD1206-050的核心参数围绕“低损耗、快动作、小体积”设计,关键参数及实际意义如下:

  • 保持电流(Ihold):500mA,即电路正常工作时,持续电流不超过500mA则不会触发保护,适配小功率负载;
  • 跳闸电流(Itrip):1A,当电流达到1A及以上时,器件会在100ms内快速动作(跳断),及时切断故障电路;
  • 最大耐受电流(Imax):100A,可承受瞬间浪涌电流(如开机冲击、静电放电等)而不损坏,避免误动作;
  • 最大工作电压(Vmax):6V,适配常见低电压电路(如5V USB、3.7V电池等),覆盖主流消费电子供电场景;
  • 初始阻值(Rmin):150mΩ(最小值),导通损耗极低,正常工作时压降小、热量少,无需额外散热设计;
  • 跳断后阻值(Rmax):700mΩ(最大值),跳断状态下保持低阻,不影响故障检测与后续恢复;
  • 消耗功率(Pmax):600mW,正常工作时功耗可控,适合电池供电的便携设备;
  • 动作时间(Tmax):100ms,满足大多数电子设备的过流保护响应要求,避免敏感元件损坏。

三、关键性能优势

  1. 低导通损耗:初始阻值仅150mΩ(最小值),远低于普通贴片保险丝(通常几百mΩ至几Ω),导通时压降仅约0.075V(500mA电流下),可直接用于电池供电设备,延长续航;
  2. 快速动作响应:最大动作时间100ms,能在过流故障发生后快速切断电路,保护后端芯片、电池等敏感元件免受不可逆损坏;
  3. 大浪涌耐受:100A的瞬间电流耐受能力,可有效抵御开机浪涌、负载突变等突发大电流,避免因误动作导致设备频繁重启;
  4. 自恢复特性:跳断后无需更换,故障排除(如短路解除、负载恢复正常)后自动恢复导通,降低维护成本与人力投入;
  5. 小体积高密度:1206标准贴片封装(尺寸约3.2mm×1.6mm),适配自动化SMT贴装,适合手机、平板、充电宝等小型化设备的高密度布局。

四、环境适应性与可靠性

ASMD1206-050的工作温度范围为**-40℃~+85℃**,可适应从低温环境(如北方户外便携设备)到高温环境(如密闭空间内的电源模块)的广泛场景;经可靠性测试验证,多次动作后阻值衰减小(跳断后最大700mΩ),可满足消费电子产品5-10年的生命周期要求。

五、典型应用场景

ASMD1206-050的参数特性使其适配多种低电压过流保护场景:

  1. 便携电子设备:手机、平板、智能手表的电池过流保护(3.7V-4.2V电池);
  2. USB接口与快充电路:5V/9V/12V USB充电端口的过流防护(适配6V最大电压);
  3. 小型电源模块:5V DC-DC电源输出端的过流保护(如路由器、机顶盒的内部电源);
  4. 消费电子配件:充电宝、无线耳机、蓝牙音箱的电池与电路保护;
  5. 小型工业控制:低电压(5V-6V)传感器、执行器的过流防护。

六、封装与兼容性

1206贴片封装符合IPC标准,可兼容常规SMT贴片机的吸嘴与贴装参数,无引线设计减少了寄生电感与电容,提升电路的高频稳定性;同时,封装的耐热性满足回流焊工艺要求(260℃峰值温度10秒内),适合大规模自动化生产。

综上,ASMD1206-050自恢复保险丝凭借低损耗、快响应、小体积与自恢复特性,成为低电压电路过流保护的高性价比选择,可覆盖消费电子、便携设备等多领域的防护需求。

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
