产品概述:RF1347-000 自恢复保险丝

产品简介

RF1347-000 是由美国力特(Littelfuse)公司推出的一款高性能自恢复保险丝。该产品采用PPTC(Polymeric Positive Temperature Coefficient)材料设计,能够在电路中过载或短路时自动限制电流,从而保护电路及其连接的设备。其独特的设计使得RF1347-000能够在电流恢复正常后自动复位,避免了传统保险丝需要更换的烦恼。这款自恢复保险丝广泛应用于电动车、家用电器、计算机、通信设备以及其他需要过载保护的电子系统中。

主要参数

  • 保持电流:500mA
  • 初始态阻值:最小值200mΩ
  • 商品分类:自恢复保险丝
  • 最大动作时间:100ms
  • 最大电压:13.2V
  • 最大电流:100A
  • 跳闸电流:1.1A

工作原理

RF1347-000 自恢复保险丝具有独特的热敏特性。当流过的电流超过设定的跳闸电流(1.1A)时,保险丝内的材料会迅速加热并膨胀,形成阻碍电流通过的高阻状态。当电流降至保持电流(500mA)以下时,材料随之冷却并恢复正常的低阻状态,允许电流再次通过。这个过程可以反复进行,无需更换保险丝,显著提高了其使用的便利性和经济性。

应用领域

RF1347-000 自恢复保险丝适用于多种应用场景:

  1. 电动车:保护电池管理系统及电机控制器,避免由于过载引发的电路损坏。
  2. 家用电器:如洗衣机、微波炉等,确保设备在异常情况下能够安全工作。
  3. 计算机及周边设备:保护电源及数据信号线路,确保系统稳定性。
  4. 通信设备:为基站、无线路由器等提供过载保护,确保网络畅通无阻。

产品优势

  • 自动复位功能:RF1347-000 具有良好的自恢复功能,一旦电流异常,保险丝能够迅速跳闸,电流恢复正常后又能自动复位,极大提高了维护的便利性。
  • 快速响应时间:产品的最大动作时间为100ms,这个快速反应保证了在电路发生过载时,能够迅速切断电流,从而保护设备不受损害。
  • 高额定电流承载能力:RF1347-000 最高可以承受100A的瞬时电流,为多种高功耗设备提供了可靠的保护方案。
  • 低初始阻值:200mΩ的初始态阻值可以确保在正常工作状态下,电路能够拥有顺畅的电流流动,避免因电阻过大而导致的能量损耗。

安装和使用注意事项

在使用RF1347-000 自恢复保险丝时,应注意以下事项:

  1. 正确规格选择:根据实际应用场景的需求,选择合适的保持电流和跳闸电流,确保保险丝能够充分发挥保护作用。
  2. 环境适应性:确保该元件的工作环境符合其规格要求,避免在极端温度、潮湿或其他不利环境下使用。
  3. 定期检查:尽管自恢复保险丝可自动复位,但仍建议定期检查确保其功能正常,避免潜在的电路安全隐患。

结论

RF1347-000 自恢复保险丝凭借其卓越的保护性能、自恢复功能以及广泛的应用范围,成为现代电子产品中不可或缺的保护元件。其可靠的性能和便利的操作为用户提供了更为安全和高效的电路保护解决方案。Littelfuse作为领先的电子保护产品制造商,凭借多年行业经验和技术积累,RF1347-000尤为值得信赖。

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
