LUTE(陆特)2920L200/48GR是一款针对低压直流系统设计的贴片式自恢复过流保护器件(PPTC),凭借小型化封装、宽电压耐受、低功耗特性,适配多场景下的持续过流防护需求,替代传统一次性保险丝的重复更换成本。
该产品采用2920贴片封装,尺寸为7.98mm(长)×5.44mm(宽),属于小型化表面贴装器件,支持自动化贴装工艺,可直接集成于高密度PCB布局中,满足消费电子、工业控制等领域对空间紧凑的要求。作为陆特品牌的主流过流保护产品,其核心定位是为48V以下低压直流系统提供“自恢复、免维护”的过流防护,核心优势在于“抗瞬态浪涌+重复使用”。
2920L200/48GR的参数设计精准匹配中等功率低压场景,核心参数及实际意义如下:
该器件基于聚合物正温度系数(PPTC)材料工作,动作逻辑清晰:
其4.5s的动作时间属于“慢响应”范畴,核心优势是抗瞬态浪涌能力强——针对电机启动、电容充电等短时间大电流场景,不会因瞬态浪涌误触发,仅对持续过流(如负载短路、过载)进行有效保护。
结合参数特性,2920L200/48GR主要适配以下场景:
综上,LUTE 2920L200/48GR以“小型化、低功耗、宽温自恢复”为核心优势,是低压直流系统过流防护的高性价比选择。

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.
