MSMD110-33V 产品概述
一、产品简介
MSMD110-33V 为台湾陆海（Luhai）出品的一款 SMD 可复位保险元件，封装为业界常见的 1812（尺寸约 4.73 × 3.41 × 1.8 mm）。该元件设计用于对电子线路进行过流保护，能在出现短路或异常过载时迅速限流并在故障消除后自动恢复，适合消费电子、电源模块、通信与工业设备等场景。
二、主要电气参数
- 最高工作耐压（Vmax）：33 V
- 最大承受电流（Imax）：100 A（瞬时或短时冲击能力，须结合具体应用验证）
- 保持电流（Ihold）：1.1 A（器件在该电流下应长期不动作）
- 跳闸电流（Itrip）：2.2 A（器件在该过流条件下开始显著升阻以限制电流）
- 动作时间：约 300 ms（在接近或等于指定跳闸电流时的典型响应时间）
- 功耗（Pd）：800 mW（工作时的最大或典型耗散，受环境温度影响）
- 初始态电阻（Rmin）：50 mΩ（上电或复位后端到端的低阻值）
- 跳断后电阻（R1max）：250 mΩ（动作后进入高阻限流状态的最大阻值）
三、结构与封装
MSMD110-33V 采用 1812 SMD 封装，适合自动贴装与回流焊工艺。外形尺寸为 4.73 mm × 3.41 mm × 1.8 mm，体积小、占板面积低，便于在空间受限的板级设计中使用。封装及引脚应按制造商推荐的回流曲线与焊盘布局进行，以保证焊接可靠性和热传导性能。
四、典型应用
- USB、外围接口及总线保护（适用于不超过 33 V 的系统）
- 开关电源与 DC-DC 模块输入保护
- 电池管理与电源线路的过流保护（例如 12 V / 24 V 系统的辅助电路）
- 通信设备、路由器和工业控制模块的局部保护
五、选型与使用建议
- 正常工作电流应小于 Ihold，避免长期接近保持电流以防止误动作或升温。
- 设计时考虑 Itrip 与 Ihold 的裕量，保证在短时浪涌（例如插拔、启动电流）下不误动作，同时能在真正过载时可靠限流。
- 安装位置应避免与高温器件紧密靠近，以降低环境温度对动作特性的影响；必要时预留散热路径或采用热隔离设计。
- 对于频繁发生的故障情形，应评估器件重复复位后的性能稳定性与寿命，并在必要时考虑并联或级联保护方案。
六、可靠性与安全性
MSMD110-33V 在动作后仍保持中等阻值（R1max ≤ 250 mΩ），可在故障移除后自动恢复初始低阻状态，便于维护与重复使用。产品属于被动限流保护元件，应配合系统级保护（如过压保护、热熔断等）共同构成完善的安全策略。详细的环境与加速寿命数据建议参考厂商完整规格书。

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.
