0402L050SLKR 是 Littelfuse(美国力特)生产的一款高性能聚合物 PTC(正温度系数)自恢复保险丝,专为表面贴装应用设计。这款保险丝在保护电路方面具备独特的优势,能够有效防止因过流而导致的电路损坏,同时提供了便捷的自恢复功能,使电路在恢复正常工作条件后,无需更换保险丝。
自恢复特性: 0402L050SLKR 具有自恢复的特点,即在电流超出设定值后,会瞬间跳断电路,但一旦返回到安全工作条件,该保险丝会自动恢复到正常状态,避免了替换部件带来的时间和成本消耗。
低电阻值: 初始电阻值低至 40 mOhms 的特性确保了在正常工作状态下,电路的电流损耗最小。同时,即使在完全跳断后,最高可允许的电阻值也仅为 400 mOhms,确保了在突然断路情况下的低热量产生。
宽广的工作温度范围: 该款自恢复保险丝支持的工作温度范围为 -40°C 到 85°C,适应各种恶劣环境,适合于消费电子、通信设备、工业设备和汽车等多种应用。
小型化设计: 封装尺寸为0402(1005公制),即 1.00mm x 0.50mm,极大地满足了现代电子设备不断追求的小型化需求。无论是在手机、平板电脑、智能家居产品,还是在医疗设备和工业控制系统中,其小巧的尺寸都不会造成布局上的困难。
高电流承载能力: 此产品的最大电流可达到 50A,确保在高负荷的电路中也能提供有效的保护,避免过流损害设备,提高整个系统的稳定性与安全性。
0402L050SLKR 聚合物 PTC 自恢复保险丝适用于多种电路保护需求,主要应用包括:
0402L050SLKR 自恢复保险丝凭借其出色的电流保护能力和小巧的封装设计,成为当今电子产品中不可或缺的重要保护部件。无论是对于设计工程师还是终端用户,该产品都提供了一种高效、灵活且可靠的解决方案,确保电子设备在各种条件下安全运行。选择 0402L050SLKR,不仅是选择保护设备的有效措施,更是在追求电子设备高性能和高安全性的重要一步。

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.
