SMD1812P260TF — 8V 2.6A 1812 自恢复保险丝 产品概述
一、产品简介
SMD1812P260TF 是 RUILON（瑞隆源）出品的一款 SMD 片式自恢复保险丝（PTC resettable fuse），封装规格为 1812（尺寸 4.73mm × 3.41mm × 1.5mm）。该器件针对短路和过流保护设计，在达到跳闸电流后迅速增加阻值限制电流，通过去除过流源可自动冷却并回复低阻态，适合各种便携设备和电源保护应用。
二、主要技术参数
- 额定最大耐压（Vmax）：8 V
- 最大电流（Imax）：35 A
- 保持电流（Ihold）：2.6 A（器件在不触发的连续最大安全电流）
- 跳闸电流（Itrip）：5 A（典型触发电流）
- 功耗（Pd）：800 mW
- 初始阻值（Rmin）：10 mΩ
- 跳断后最大阻值（R1max）：50 mΩ
- 动作时间：2.5 s（达到触发状态的参考时间）
- 工作温度范围：-40 ℃ ～ +85 ℃
- 封装：1812（尺寸详见上文）
三、产品特性与优势
- 小型 SMD 封装，便于自动化贴装与批量生产；
- 低初始阻值（10 mΩ），对电路压降影响小；
- 高峰值承受能力（Imax 35A），能应对瞬态大电流冲击；
- 可自恢复，无需更换，降低维护成本；
- 工作温度范围宽，适配多种环境条件。
四、典型应用场景
- 移动电源、便携式设备的输出保护；
- USB、数据接口及充电线路过流保护；
- 电池管理系统（BMS）与一次电池保护；
- 电机驱动、LCD 背光与小功率电源模块的短路防护；
- 任何需在 8V 以下直流系统中实现自动复位过流保护的场合。
五、使用与布板建议
- 将器件置于被保护线路的靠近来源一侧，缩短保护区域线路长度；
- 保持良好散热通道，适当增大周围铜箔面积以便热量散出；
- 避免靠近热敏元件或高发热器件安装；
- 贴片回流时请遵循制造商的焊接温度曲线，避免长时间高温暴露；
- 设计时以 Ihold 为长期工作电流基准，留出足够裕量以避免误触发。
六、选型与订购信息
型号：SMD1812P260TF
品牌：RUILON（瑞隆源）
封装：1812
在选型时以实际工作电压、连续电流和可能出现的短路峰值电流为依据，优先保证长期工作电流低于 Ihold，并考虑环境温度对保持电流的影响。若需样品、数据手册或批量采购信息，请联系供应商或官方渠道获取完整规格书与可靠性试验数据。

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.
