0805L050/30AR自恢复保险丝产品概述

一、产品核心定位与适用场景

0805L050/30AR是LUTE(陆特)品牌推出的0805封装自恢复过流保护器件,核心功能是在30V以下电路中实现过电流故障的自动防护与恢复。其保持电流500mA、跳闸电流1A的参数特性,精准匹配中小电流电路的防护需求,无需手动更换熔断保险丝,可重复使用,降低系统维护成本。

二、关键电气参数深度解析

该器件的电气参数经过针对性设计,适配多场景需求:

  • 耐压(Vmax=30V):最大工作电压上限,确保30V及以下电路稳定运行,避免电压击穿风险;
  • 保持电流(Ihold=500mA):常温下可长期稳定工作的最大电流,电路电流不超此值时,器件保持低阻状态,不影响正常功能;
  • 跳闸电流(Itrip=1A):电流达1A时,器件在100ms动作时间内触发跳闸(阻值骤增),快速切断故障电流,保护芯片、电池等敏感元件;
  • 初始态阻值(Rmin=100mΩ):常态最小电阻仅0.1Ω,正常工作功耗极低(Pd=800mW),不影响电路效率与信号完整性;
  • 跳断后阻值(R1max=850mΩ):跳闸后阻值提升至约8倍初始值,有效限制故障电流,防止后端器件损坏;
  • 宽温范围(-40℃~+85℃):覆盖工业级与消费电子级环境温度,适配户外设备、车载辅助电路等场景。

三、机械与封装特性

0805L050/30AR采用标准0805贴片封装,尺寸为2.2mm(长)×1.5mm(宽)×1.1mm(高),具备以下优势:

  • 兼容主流贴片生产线,无需额外调整生产工艺;
  • 体积紧凑,适配高密度PCB设计(如智能手机、智能穿戴的小型化需求);
  • 封装一致性好,焊接可靠性高,降低生产良率风险。

四、典型应用领域示例

结合参数特性,该器件广泛应用于以下场景:

  1. 消费电子:智能手机、平板电脑的电池保护电路(单节/多节锂电池辅助过流防护)、耳机充电盒的充电电路;
  2. 智能穿戴:智能手环、手表的电源模块过流保护(适配小体积、低功耗需求);
  3. 小型电源:5V/12V小功率开关电源的输出端(如路由器、机顶盒的电源防护);
  4. 工业控制:低电压(≤30V)传感器模块、PLC输入输出端口的过流防护(宽温特性适配工业环境);
  5. 汽车电子:车内USB充电口、低电压辅助传感器的过流保护(需结合汽车级认证,宽温基础适配)。

五、产品核心优势总结

  1. 自恢复免维护:过流故障排除后(如负载短路解除),器件自动恢复低阻状态,无需手动更换保险丝,降低系统维护成本;
  2. 低损耗高效率:初始态低阻值(100mΩ)确保正常工作时功耗可忽略,不影响电路性能;
  3. 快速响应保护:100ms动作时间平衡保护速度与误触发(避免瞬间脉冲误跳闸),精准保护后端器件;
  4. 宽温场景适配:-40℃至+85℃的温度范围,覆盖大部分工业与消费电子应用场景;
  5. 小型化高密度:0805封装适配小型化产品趋势,满足高密度PCB设计需求。

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
