产品概述:SMD100F-2

产品背景

SMD100F-2是由美国力特(Littelfuse)推出的一款聚合物自恢复热保护组件,属于其知名的PolySwitch系列。该系列元件专注于提供过流保护解决方案,广泛应用于各种消费电子设备、工业机器人、汽车电子、LED照明等领域。与传统的熔断器和保险丝相比,SMD100F-2具有更高的可靠性和使用便捷性,尤其在瞬态过流情况下可以快速恢复供电。

基础参数

  • 类型:聚合物自恢复过流保护器件
  • 电压 - 最大值:最大承受电压为30V,确保在绝大多数电路中的安全使用。
  • 电流 - 最大值:额定最大工作电流为40A,使其具备良好的电流承载能力。
  • 电流 - 保持 (Ih)(最大值):保持电流设定为1.1A,低于这一电流值时设备将正常工作。
  • 电流 - 跳断 (It):该产品的跳断电流为2.2A,当触发该值时,设备会进入保护状态,切断电路。
  • 跳断时间:在超过跳断电流的情况持续500毫秒后会自动断开,以防组件和电路受到损害。
  • 电阻 - 初始 (Ri)(最小值):初始电阻为120毫欧,确保电流传导的效率。
  • 电阻 - 跳断后 (R1)(最大值):跳断后的电阻可达480毫欧,保证了一定的电流隔离。
  • 工作温度:适用工作温度范围在-40°C至85°C,适合多数工业及消费环境。
  • 安装类型:该组件采用表面贴装技术(SMD),便于在现代高密度电路板上进行集成安装。
  • 封装/外壳:采用2-SMD封装规格,尺寸为持续性的改善和小型化设计,确保在空间受限的应用中也能方便使用。
  • 尺寸:该产品的尺寸为0.290英寸长 × 0.202英寸宽(7.36mm × 5.12mm),厚度不超过0.118英寸(3.00mm),非常适合轻薄型设备。

主要特点

  1. 高效自恢复功能:SMD100F-2是自恢复的且无铅设计,即使在过流条件下也不会损坏,可以多次使用,显著降低了维护成本。
  2. 灵活的电流承载:凭借其高达40A的额定电流,SMD100F-2能够适用于各种电气设备,特别是在短路或过负载情况下提供可靠保护。
  3. 高度的温度适应性:宽广的工作温度范围确保了设备即使在极端环境下也能够稳定运行。
  4. 便于安装的设计:SMD封装形式适应现代电路板设计,无需额外的安装工具,减少了生产成本和时间。
  5. 强大的安全性:具有较低的初始电阻,使其在使用时产生的热量降低,进一步提升了安全性。

应用场景

SMD100F-2的设计使其可广泛应用于以下领域:

  • 消费电子:如智能手机、平板电脑、液晶显示器等。
  • 工业设备:用于自动化仪器、机器人等设备的电源保护。
  • 汽车电子:在电动窗、灯光控制、音响系统等提供过流保护。
  • LED照明:尤其在高功率LED驱动电路中,防止由于电流冲击导致的损坏。

总结

Littelfuse的SMD100F-2聚合物自恢复热保护器具备出色的电流承载能力与广泛的适用场景,凭借其简单有效的保护机制,已成为现代电子设备不可或缺的保护元器件之一。在研发和产品设计过程中,选择SMD100F-2将为您的电子产品提供高效、可靠的过流保护解决方案。

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
