0603L004YR 产品概述

概述: 0603L004YR是一种聚合物热敏电阻式自恢复保险丝(PTC Resettable Fuse),由美国力特(Littelfuse)生产。该产品采用0603(1608公制)表面贴装型封装,专为保护电路免受过电流引起的损坏而设计。其最大电压为24V,允许的最大电流为20A,电流保持值为40mA,跳断电流为120mA。这种设计使得0603L004YR在高电流和高压的应用场景中,能够高效地保护电路,防止因过载导致的电子元器件的故障。

技术参数: 0603L004YR的主要参数包括:

  • 类型: 聚合物
  • 电压 - 最大值: 24V
  • 电流 - 最大值: 20A
  • 电流 - 保持(Ih)(最大值): 40mA
  • 电流 - 跳断(It): 120mA
  • 跳断时间: 1秒
  • 电阻 - 初始(Ri)(最小值): 4 Ohms
  • 电阻 - 跳断后(R1)(最大值): 40 Ohms
  • 工作温度: -40°C至85°C
  • 安装类型: 表面贴装型
  • 封装/外壳: 0603(1608公制),凹陷
  • 大小 / 尺寸: 0.063" 长 x 0.032" 宽(1.60mm x 0.80mm)
  • 厚度(最大值): 0.030"(0.75mm)

工作原理: PTC保险丝的核心原理在于其特殊的聚合物材料能在达到一定的温度时迅速增加其电阻值,从而限制流过电路的电流。当电流超过其额定跳断值(120mA)时,PTC保险丝会迅速跳断电流,并在冷却到安全温度后自动恢复到其初始状态。这一特性使得0603L004YR可以多次使用,避免了传统熔断器在过载后需要更换的缺点。

应用场景: 0603L004YR广泛应用于各种电子设备中,主要包括:

  • 消费电子产品: 如手机、平板电脑和笔记本电脑等,保护其敏感电路免受意外的电流冲击。
  • 工业自动化: 在马达驱动器和传感器等设备中,确保设备在长时间运行或异常工作情况下得到保护。
  • 家电产品: 如微波炉、冰箱和洗衣机等,预防过载导致设备故障。
  • 汽车电子: 在汽车电气系统中,有效保护各种电机、传感器及控制模块,确保车辆安全和功能的正常运行。

安装与使用: 0603L004YR的表面贴装形式与现代PCB设计兼容,便于大规模自动化生产。在安装时,建议确保元件的引脚良好焊接,并注意焊接过程中不应产生过高的温度,以免影响其性能。安装完成后,用户可以通过选用合适规格的PCB设计和电路布局,使得0603L004YR能够在不同的电气环境中发挥最佳的工作效能。

总结: 0603L004YR是一款高性能的PTC自恢复保险丝,以其卓越的电流保护能力和紧凑的封装,受到广泛欢迎。它的自动恢复特性,减少了维护成本和更换频率,非常适合各种电子设备的保护需求。作为能有效应对现代电子设备复杂电流要求的组件,它在未来的发展中将会继续扮演重要的角色。

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
