0805L010/60WR过流保护器件产品概述

一、产品基本信息

  • 品牌:LUTE(陆特)
  • 产品类型:高分子聚合物正温度系数(PPTC)自恢复过流保护器件
  • 型号:0805L010/60WR
  • 封装形式:0805贴片封装
  • 核心功能:针对中低压电路的过流保护,故障排除后自动恢复低阻态

二、核心电气参数详解

该器件参数覆盖小功率负载保护场景,关键参数意义如下:

1. 电压与电流核心参数

  • 最大工作电压(Vmax):60V
    器件长期稳定工作的最高电压,故障状态下仍可承受该电压而不击穿,适配12V~60V中低压电路。
  • 最大故障电流(Imax):10A
    瞬时可承受的最大短路电流(不导致永久损坏),避免极端故障烧毁器件。
  • 保持电流(Ihold):100mA
    正常工作时的最大允许电流——电流≤100mA时,器件保持低阻态,无保护动作。
  • 跳闸电流(Itrip):300mA
    触发保护的最小电流——电流≥300mA时,器件在1.5s内切换至高阻态,限制故障电流。

2. 阻值与功率参数

  • 初始态最小阻值(Rmin):750mΩ
    正常工作时的低阻值,100mA负载下仅产生0.075V压降,对电路效率影响极小。
  • 跳断后最大阻值(R1max):8Ω
    保护触发后阻值迅速升至8Ω以上,将故障电流限制在安全范围(60V/8Ω=7.5A,远低于Imax)。
  • 耗散功率(Pd):500mW
    正常工作时的最大允许功率损耗,避免器件因过热损坏。

3. 动作与环境参数

  • 动作时间:1.5s(典型值)
    在Itrip=300mA条件下,器件从低阻态切换至高阻态的时间,兼顾响应速度与误触发防护。
  • 工作温度范围:-40℃~+85℃
    宽温适应性,可用于户外、车载等极端环境。

三、封装与物理特性

0805封装尺寸为长2.3mm×宽1.5mm×高0.9mm,具备以下优势:

  • 适配自动化贴片生产,提高电子制造效率;
  • 节省PCB布局空间,适合高密度电路(如便携式设备、小型模块);
  • 符合RoHS环保标准,满足绿色制造要求。

四、典型应用场景

该器件因小封装、宽参数范围,适用于以下场景:

  1. 消费电子:智能手机、平板电脑的电池辅助保护、USB接口过流防护;
  2. 便携式设备:蓝牙耳机、智能手环的电源线路保护;
  3. 小型家电:加湿器、智能灯泡的控制电路保护;
  4. 工业控制:低压传感器模块、小型PLC的I/O线路保护;
  5. 电源适配器:5V/12V小功率适配器的输出过流保护。

五、关键性能优势

  1. 低损耗高兼容:初始阻值仅750mΩ,不影响小功率电路的效率与信号完整性;
  2. 自恢复免维护:故障排除后(如短路移除),器件冷却自动恢复低阻态,无需更换;
  3. 宽温可靠:-40℃~+85℃工作范围,通过温度循环、焊接可靠性测试;
  4. 快速响应:1.5s动作时间,可有效避免故障扩散损坏后端电路。

六、使用注意事项

  1. 电压限制:电路工作电压不得超过60V,否则可能击穿器件;
  2. 电流匹配:正常负载电流需≤100mA,避免误跳闸;
  3. 故障电流:瞬时短路电流不得超过10A,否则可能永久损坏;
  4. 焊接规范:遵循0805封装工艺(回流焊温度≤260℃,时间≤10s),避免高温损伤;
  5. 故障排除:保护触发后,需先移除故障源,待器件冷却(约2~5分钟)后再恢复工作。

该器件凭借小封装、宽参数与自恢复特性,成为中低压小功率电路过流保护的优选方案,适配多种电子设备的可靠性设计需求。

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
