ASMD1206-075-30V自恢复保险丝产品概述

一、产品基本定位与品牌背景

ASMD1206-075-30V是集电通(JDTfuse) 推出的一款贴片式自恢复过流保护器件,核心作用是在电路出现过流/过温时快速切断电流,故障排除后自动复位,无需人工更换。集电通作为国内专注于过流保护领域的品牌,该系列产品依托成熟的聚合物材料配方与封装工艺,具备高可靠性、一致性与成本优势,广泛适配消费电子、车载、工业等中低功率场景。

二、核心电气参数深度解析

该产品参数精准匹配中低功率电路的保护需求,关键参数解读如下:

  1. 保持电流(750mA):额定环境温度下,器件持续导通且不动作的最大电流(电路正常工作电流需≤750mA);
  2. 跳闸电流(1.5A):过流触发的最小电流(约为保持电流的2倍),电流≥1.5A时器件快速动作;
  3. 最大电压(30V):适配直流/交流电压≤30V的电路,超出则可能导致绝缘失效;
  4. 初始态阻值(最小90mΩ):正常导通时的低阻值设计,可显著降低导通损耗(正常工作功耗仅600mW);
  5. 跳断后阻值(最大500mΩ):动作后保持高阻态,确保故障时漏电流极小,避免二次损坏;
  6. 最大动作时间(200ms):过流触发后≤200ms切断电流,快速保护后端敏感元器件(如芯片、电池);
  7. 最大浪涌电流(100A):短时间耐受100A浪涌(如开机脉冲、静电放电),抗浪涌能力强;
  8. 工作温度(-40℃~+85℃):宽温设计,适配极端环境(如北方户外设备、车载高温场景)。

三、封装设计与物理特性

采用1206贴片封装(尺寸1.2mm×0.6mm×0.5mm),具备三大优势:

  1. 小型化:适配高密度PCB设计(如智能穿戴、小型控制器),节省电路空间;
  2. 自动化兼容:可直接用于SMT自动化贴装线,提高生产效率与一致性;
  3. 散热优化:封装结构强化热传导,动作后热量快速散发,复位速度更快。

四、性能优势与差异化特点

  1. 低功耗高可靠:初始态90mΩ低阻值+600mW小功耗,减少电路自身发热,提升系统稳定性;
  2. 快速保护响应:200ms内动作,避免敏感元器件因过流损坏;
  3. 宽温抗浪涌:-40~85℃宽温+100A浪涌耐受,适配复杂环境;
  4. 自恢复免维护:故障排除后自动复位,无需更换,降低设备维护成本;
  5. 批量一致性好:集电通成熟工艺确保批量产品参数偏差小,适合量产应用。

五、典型应用场景

结合参数特点,该产品适用于以下场景:

  1. 消费电子:手机、平板、智能手表的电池过流保护(避免充电过流损坏电池);
  2. 车载电子:车载充电器、仪表盘模块、行车记录仪的过流保护(宽温适配车载环境);
  3. 工业控制:小型PLC、传感器模块、电机驱动电路的过流保护;
  4. 通讯设备:路由器、交换机、光模块的电源输入保护;
  5. 新能源:小型储能电池、无人机电池的过流保护。

六、选型与使用注意事项

  1. 电流匹配:正常工作电流≤750mA(高温环境需降额,如85℃时保持电流约600mA);
  2. 电压匹配:电路电压≤30V,避免过压击穿;
  3. 浪涌评估:若浪涌频繁(如高频脉冲电路),需额外增加瞬态抑制器件;
  4. 贴装工艺:遵循1206封装SMT参数(如回流焊温度曲线),避免虚焊;
  5. 复位条件:故障排除后,需等待器件温度降至常温(约1分钟)即可自动复位。

总结

ASMD1206-075-30V是一款高性价比的贴片自恢复保险丝,凭借低功耗、快速响应、宽温抗浪涌等特点,可替代传统一次性保险丝,广泛应用于中低功率电子设备的过流保护,是量产场景的理想选择。

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.
