产品简介
1812L050/60MR 是 Littelfuse(美国力特)出品的一款高性能聚合物 PTC(正温度系数)自恢复保险丝,专为提供过流保护而设计。这款保险丝广泛应用于电子设备和电路中,为敏感元件提供可靠的安全保障。具备自动恢复的特性,当过流条件解除后,保险丝自会恢复到正常状态,避免了传统熔断器的更换麻烦。
主要参数
设计与应用
1812L050/60MR 的设计经过精心考量,以确保在高电流负载下能够有效保护电路。以其表面贴装的形式,适合于各种电路板的高密度布局,帮助用户节省空间并提高设计的灵活性。该产品的最大操作电流为10A,能够在多种电流负载情况下提供出色的保护。
该保险丝特别适合在以下场合中使用:
操作与特性
聚合物 PTC 自恢复保险丝的主要优点在于其自恢复能力。在电路出现过载或短路时,保险丝会快速跳闸,切断电流。在该条件解除后,保险丝会在一定时间内恢复到正常状态,无需人工干预或更换,极大地提升了维修便利性和设备的使用寿命。
1812L050/60MR 的快速反应时间(最大动作时间为150ms)确保了及时切断过流,保护后端电路不受损害。此外,保险丝的保持电流为500mA,能有效防止因瞬态电流导致的误动作,确保在正常工作状态下电路能畅通无阻。
环境适应性
在设计过程中,考虑到了广泛的应用环境,这款保险丝的工作温度范围为-40°C至85°C,适应多种恶劣的工作条件,确保在极端天气和高温环境中也能够稳定运行。聚合物的材质赋予其良好的耐用性,确保在长时间使用下仍能保持良好的性能。
总结
综上所述,1812L050/60MR 聚合物 PTC 自恢复保险丝是一款具有高度可靠性的保护元件,能够在电流负载情况下为电子设备提供必要的保护。其自动恢复、快速响应、优良的环境适应性和容易集成的特性,使其成为各种电子和电气应用的理想选择。在设计电路时考虑使用此产品,可以显著提高整个系统的安全性和稳定性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
