RF1344-000 是 Littelfuse(美国力特)推出的一款 1206 封装自恢复保险丝(PPTC),型号标注为 “PPTC 48V .16A-HD 10A”。器件设计用于在直流或低频工况下对过流和短路提供重复性的热式限流保护。器件的尺寸为 3.2 mm × 1.6 mm(1206 封装),便于表面贴装(SMT)于密集 PCB 布局中,适合空间受限且要求可靠过流保护的电子模块。
注:上述参数为典型/额定值,具体应用时请以 Littelfuse 官方数据表为准,并考虑工作温度、PCB 散热与封装热阻的影响。
不适合用于长期连续大电流负载或对瞬态电流无容忍需求的场合(例如电机直接驱动、持续性大电流供电),因为保持电流仅为 160 mA。
RF1344-000 以小尺寸与较低保持电流为特征,适合在 48 V 直流母线和低电流保护场景中使用。当设计目标是对小电流回路提供可重复、自恢复的保护,并要求节省 PCB 空间时,该器件是优选之一。最终选型请结合实际最大工作电流、环境温度、短路能量与厂商最新数据表进行核对验证。

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.
