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。
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。
RF1347-000 自恢复保险丝适用于多种应用场景:
在使用RF1347-000 自恢复保险丝时,应注意以下事项:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
