1812L110/33GR 产品概述
一、产品简介
1812L110/33GR 是 LUTE（陆特）推出的一款 1812 封装自恢复式聚合物过流保护元件（Polymeric PTC resettable fuse），体积小、响应可靠，专为汽车电子、工业控制接线端口的过流与过温保护设计。其最大耐压 33V，最大承受瞬时电流可达 40A，适配 12V/24V 系统保护需求。
二、主要电气参数
- 耐压 (Vmax)：33V
- 最大电流 (Imax)：40A
- 保持电流 (Ihold)：1.1A（常温下）
- 跳闸电流 (Itrip)：2.2A（典型）
- 功耗 (Pd)：1.2W
- 初始态阻值 (Rmin)：45mΩ
- 跳断后阻值 (R1max)：250mΩ
- 动作时间：300ms
- 工作温度：-40℃ ~ +85℃
三、封装与尺寸
- 封装：1812
- 外形尺寸：长 4.73mm × 宽 3.41mm × 高 1.3mm
小体积便于在受限空间内布局，适合表面贴装与自动化贴片生产。
四、产品特点与优势
- 自恢复设计：过流后自动限流并可恢复，减少更换维护成本。
- 响应稳定：典型 300ms 动作时间，能有效截断短时过流故障。
- 低初始电阻：45mΩ 起，降低正常工作时电压降与发热。
- 宽温度范围：-40℃ 至 +85℃，满足汽车及严苛工业环境要求。
- 标准封装：1812 兼容常见 PCB 布局与回流焊工艺。
五、典型应用场景
- 汽车电子控制单元（ECU）电源与外设端口保护
- 工业控制器与接线端子过流/过温保护
- 通信设备、电源模块、点烟器/USB 接口等电流受限场合
六、选型与使用注意
- 工作电流选择：建议 Ihold 大于实际最大工作电流并留有裕量，避免误动作。
- 环境与散热：高环境温度会降低保持电流，请参照温度特性曲线选型并留出散热空间。
- 电压限制：不可超过 33V 直流应用；非线性瞬态需配合浪涌抑制器。
- 不适用场景：不可作为短路保护替代长期大电流开关件，不推荐在持续过负载下长期工作。
- 焊接建议：遵循陆特的回流焊温度曲线，避免超温造成特性漂移。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
