0603L010/33XR是陆特(LUTE)品牌推出的小型化自恢复过流保护器件,采用0603封装,针对低压小电流电路的过流防护需求设计,具备精准动作、低损耗、自恢复等核心优势,广泛适配便携电子、智能穿戴等高密度集成场景。
该产品属于聚合物自恢复保险丝(PPTC)范畴,核心作用是在电路出现过流(如短路、过载)时快速阻断电流,保护后端敏感元器件(如电池、IC、传感器);故障排除后自动恢复导通,无需人工更换,有效降低维护成本与产品返修率。其技术定位聚焦低压(≤33V)、小电流(≤100mA常态) 场景,兼顾防护可靠性与电路兼容性。
产品的核心性能由以下关键参数定义,需结合应用场景精准匹配:
参数名称 数值 技术意义 最大耐压(Vmax) 33V 电路正常工作/过流状态下可承受的最高电压,超过则可能击穿损坏 最大脉冲电流(Imax) 40A 瞬间(微秒级)可承受的浪涌电流极限,避免雷击、静电等脉冲损坏 保持电流(Ihold) 100mA 常态下稳定导通的最大电流,电路工作电流需≤Ihold,否则误触发保护 跳闸电流(Itrip) 300mA 触发保护动作的最小电流,电流≥Itrip时,600ms内跳断,阻断过流 最大功耗(Pd) 500mW 常态下的最大允许功耗,对应小阻值设计,降低电路发热与损耗 初始导通电阻(Rmin) 900mΩ 常态下的最小电阻,低阻值可减少电压降与功率损耗,不影响电路正常性能 跳断后阻值(R1max) 8Ω 保护动作后处于高阻态的最大阻值,有效阻断电流,保护后端器件 动作时间 600ms 在Itrip电流下从过流到跳断的时间,平衡防护灵敏度与误触发风险(如瞬间脉冲不触发) 工作温度范围 -40℃~+85℃ 宽温设计,适应低温环境(如北方户外)与高温环境(如便携设备内部发热)该产品采用0603封装(英制尺寸,对应公制1608),实际物理尺寸为:
超小型封装优势明显:
该产品主要适用于低压小电流、高密度集成的电子设备,典型场景包括:
为确保防护效果与产品寿命,需注意以下要点:
综上,0603L010/33XR凭借小型化、低损耗、精准防护与自恢复特性,成为低压小电流电路过流保护的优选器件,适配多种高密度集成场景的可靠性需求。
Request for quote
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.
