SMD1812P030TF/60 产品概述
一、产品简介
SMD1812P030TF/60 是 RUILON（瑞隆源）推出的一款微型表面贴装可复位过流保护器件，封装为业界常用的 1812 尺寸。该器件专为空间受限且工作电流较低的超便携式产品设计，具有快速动作、低初始阻抗和良好的自恢复能力，能够在过流事件解除后自动恢复导通状态，降低维修成本并提升设备可靠性。
二、主要参数
- 耐压（Vmax）：60 V
- 最大电流（Imax）：30 A
- 保持电流（Ihold）：300 mA
- 跳闸电流（Itrip）：600 mA
- 功耗（Pd）：800 mW
- 初始态阻值（Rmin）：250 mΩ
- 跳断后阻值（R1max）：3 Ω
- 动作时间：100 ms
- 工作温度：-40 ℃ 至 +85 ℃
- 外形尺寸：4.73 mm × 3.41 mm × 1.1 mm（1812 封装）
三、产品特性与优势
- 体积小、重量轻，适合对空间和重量敏感的便携终端与可穿戴设备。
- 低初始阻值提供较小的压降，保证正常工作时的能效与稳定性。
- 快速动作（100 ms）可在短时间内限制故障电流，保护后端电路。
- 跳断后阻值可达到 ≤3 Ω，有利于有效切断短路电流。
- 宽工作温度范围适应工业级环境要求。
- 可复位设计无需更换熔断器，简化售后与维护流程。
四、典型应用场景
- 超便携式消费电子（小型充电器、迷你音箱、便携式电源）
- 移动设备与外设（USB 外设、蓝牙设备、穿戴式传感器）
- 低电流检测与保护电路、通信终端电源保护、测试仪器输入端保护
- 电池保护与电源管理模块，适用于多点保护需求的系统
五、封装与安装建议
SMD1812P030TF/60 采用 1812 表面贴装封装，兼容常见 SMT 贴装与回流工艺。建议在 PCB 布局时为器件预留足够的热扩散面积并避免紧邻高发热元件，以利于散热和可靠动作。实际焊接工艺与回流温度曲线请参照瑞隆源官方焊接指南，以确保长期可靠性。
六、选型与注意事项
在选用时应根据系统最大允许电压（≤60 V）与工作电流匹配保持电流 300 mA 的特性，留有合适的裕量以避免误动作。若应用中存在较长持续过载或频繁短路情形，应评估热累积与寿命影响并考虑更高功率规格或并联方案。需要批量采购或获取样品及详细应用资料，请联系 RUILON（瑞隆源）或授权代理。

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.
