SMD1206-110/24N 熔断器（SMD）产品概述
一、产品简介
SMD1206-110/24N 是伯恩半导体（BORN）推出的一款贴片式熔断器，封装尺寸为1206（3.4 × 1.8 × 1.3 mm）。该器件适用于额定电压不超过24V 的直流或低频交流电路，提供可靠的过流保护，体积小、响应快，便于表面贴装自动化生产。
二、主要电气与机械参数
- 额定耐压（Vmax）：24 V
- 最大开断能力（Imax）：40 A（器件能够安全承受的最大故障电流峰值）
- 保持电流（Ihold）：1.1 A（长期不跳闸的电流）
- 跳闸电流（Itrip）：2.2 A（在规定时间内将动作的电流）
- 动作时间：100 ms（在Itrip 条件下典型动作时间）
- 功耗（Pd）：800 mW（额定条件下最大消耗功率）
- 初始态阻值（Rmin）：40 mΩ
- 跳断后阻值（R1max）：270 mΩ
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装尺寸：1206（长3.4 mm × 宽1.8 mm × 高1.3 mm）
三、产品特点与优势
- 小型化封装，适配工业化SMT贴片流程，节省PCB空间。
- 低初始阻值，有利于减小导通损耗与热积累。
- 明确的保持/跳闸电流比值（约2倍），便于准确保护设计与整定。
- 较高的瞬态开断能力（40A），在短路条件下具备一定的安全开断能力。
- 宽工作温度范围，适应多数民用与工业环境。
四、典型应用场景
适用于12V/24V电源分配与保护、电池组保护、便携式设备、LED驱动、通信设备及一般电子模组的短路/过流保护。对于需要体积受限且可自动化贴装的场合尤为合适。
五、选型与使用建议
- 按实际工作电流选择熔断器，留有安全裕度并考虑环境温度对保持电流的影响（高温时需降额使用）。
- 关注动作时间与浪涌电流（如启动电流、充电浪涌），必要时采用限流或软启动电路避免误动作。
- 布局时远离持续高温器件，保证良好散热；焊盘与过孔设计应符合1206封装的焊接标准。
- 兼容常见回流焊工艺，但请参照厂商推荐的回流曲线以免影响器件特性。
- 需要确认包装形式（如卷带）与器件合规认证时，请向供应商索取完整数据手册与资格证明。
六、采购与可靠性建议
订购时请标明完整型号 SMD1206-110/24N 及品牌 BORN（伯恩半导体），并索取最新数据手册、温升与浪涌测试曲线。量产前建议在目标系统内进行温度/寿命/过流试验验证，以确保在实际工况下达到预期保护效果。
注：本文为基于提供参数的产品概述，具体电气特性曲线、回流焊规范和安全认证信息请以厂方正式数据手册为准。

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.
