ASMD1206-150自恢复保险丝产品概述

一、产品基本信息

ASMD1206-150是集电通(JDTfuse) 推出的贴片式自恢复保险丝,属于聚合物自恢复保险丝(PPTC)范畴。其命名规则清晰:

  • 1206 对应国际标准贴片封装尺寸(长1.2mm×宽0.6mm),适配自动化表面贴装工艺;
  • 150 标识核心参数——保持电流1.5A,是判断适用场景的关键指标。

该器件专为低压电路过流保护设计,故障排除后自动恢复导通,无需手动更换,可降低设备维护成本。

二、核心性能参数详解

1. 电气核心参数

参数 数值 意义说明 保持电流(Ihold) 1.5A 电路正常工作时,电流≤1.5A则保持低阻导通,不影响电路运行 跳闸电流(Itrip) 3A 电流≥3A时开始动作,电阻迅速增大,切断过流路径 最大工作电压(Vmax) 6V 适配低压场景(如3.7V锂电池、5V USB供电),高压需谨慎选型 初始阻值(Rmin) 40mΩ 导通时电阻极低,正常工作功耗仅800mW,无额外发热 跳断后阻值(Rmax) 130mΩ 故障恢复后阻值仍低,不影响电路后续工作 峰值耐受电流(Imax) 100A 可承受开机浪涌、静电放电等突发电流,避免误动作

2. 时间与环境参数

  • 最大动作时间:300ms,过流时300ms内完成跳断,快速保护IC、MOS管等敏感元件;
  • 工作温度范围:-40℃~+85℃,覆盖工业级宽温需求,适用于车载、户外设备等场景。

三、典型应用场景

1. 消费电子终端

  • 手机/平板电池保护:适配3.7V锂电池电压,1.5A保持电流满足充放电需求(通常≤1.2A),过流时快速跳断保护电池与主板;
  • 蓝牙设备/智能手环:为电源模块提供保护,避免充电短路或负载异常损坏;
  • 便携式充电宝:保护输出端口,防止外接设备短路导致电源损坏。

2. 小型工业控制

  • 低压传感器模块:如温度、压力传感器信号输出端,宽温适应工业现场;
  • 小型PLC IO端口:保护端口免受过流冲击,提升设备可靠性。

3. 车载低压附件

  • 车载蓝牙/USB充电口:适应-40℃低温(北方冬季)与85℃高温(夏季车内),满足车载环境需求。

四、产品优势与特点

  1. 高集成易生产:1206封装体积小,节省PCB空间,适配SMT自动化贴装,提升生产效率;
  2. 低功耗不发热:40mΩ初始阻值+800mW功耗,正常工作无额外发热,不影响周边器件;
  3. 快速可靠保护:300ms动作时间,比传统保险丝响应更快,降低过流损坏概率;
  4. 宽温适应能力:-40℃~+85℃工作范围,超越普通消费级器件,满足 harsh 环境;
  5. 自恢复免维护:故障排除后自动恢复导通,无需更换器件,减少售后成本;
  6. 浪涌耐受强:100A峰值电流耐受,应对开机浪涌、静电放电等突发情况,减少误动作。

五、选型与使用注意事项

1. 选型匹配原则

  • 保持电流需≥电路正常最大工作电流(建议留20%余量,如正常1.2A选1.5A);
  • 工作电压需≤6V,避免高压击穿。

2. 安装注意事项

  • 焊接温度:回流焊≤260℃,焊接时间≤30s,避免高温损坏内部聚合物;
  • PCB焊盘:需符合1206封装标准(建议焊盘尺寸0.8mm×1.2mm),保证焊接可靠性。

3. 故障处理

  • 跳断后先排查故障(短路、负载过大、电压异常等),排除后等待10~30秒(温度越高恢复越快)再通电,禁止强行通电。

4. 环境限制

  • 避免长期在超过85℃或低于-40℃的环境工作,否则缩短寿命;
  • 远离腐蚀性气体(如硫化物),防止封装老化。

ASMD1206-150凭借稳定性能与高性价比,成为低压过流保护领域的常用选型,适用于对体积、响应速度、宽温有要求的电子设备。

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
