DW-1206-100-24 产品概述
一、产品简介
DW-1206-100-24 为 DOWO（东沃）出品的一款 1206 封装自恢复保险元件，适用于对过流保护、过载限制与短路保护有快速响应需求的电子系统。外形小巧、热响应迅速，适合表面贴装工艺（SMT），便于自动化生产与批量装配。产品分类暂标注为“未分类”，但其功能与常见 PPTC/自恢复保险丝一致，适合多类低压电源保护场合。
二、主要参数
- 耐压 (Vmax)：24 V
- 最大电流 (Imax)：40 A
- 保持电流 (Ihold)：1 A
- 跳闸电流 (Itrip)：2 A
- 消耗功率 (Pd)：800 mW
- 初始态阻值 (Rmin)：40 mΩ
- 跳断后阻值 (R1max)：270 mΩ
- 动作时间：100 ms
- 工作温度：-40 ℃ ~ +85 ℃
- 封装：1206（SMT）
三、工作原理
在正常电流（≤ Ihold）下，器件呈低阻状态（初始 Rmin），损耗和发热较小；当电流超过跳闸电流（≈ Itrip）时，器件温度或材料状态变化导致阻值迅速上升至跳断后阻值（不超过 R1max），从而限制通过电流保护下游电路。过流消失后器件可逐渐冷却恢复低阻态，具有重复自恢复能力。
四、主要特性
- 小封装（1206），便于高密度布板与 SMT 贴装；
- 响应快速，典型动作时间约 100 ms；
- 高承载能力（瞬态或短时峰值可达 Imax 40 A）；
- 宽工作温度范围，适应工业级应用；
- 自恢复设计减少更换维护，适合长期可靠运行。
五、典型应用
- USB/接口供电过流保护；
- 通信设备、电源模块、充电器短路保护；
- 工业控制与测量设备的线路保护；
- 电池管理与便携终端的过流防护。
六、安装与使用注意
- 建议按制造商推荐的回流焊曲线进行 SMT 贴装，避免过高温度和过长热暴露；
- 在高工作温度或密集布板环境下，应考虑适当降额，确保器件在额定 Pd 条件下可靠工作；
- 对于持续高电流或频繁热循环场合，需验证寿命与恢复特性；
- 设计时预留热散与检测空间，避免邻近敏感器件受热影响。
七、选型建议与可靠性
选择 DW-1206-100-24 时，应确认最高工作电压不超过 24 V，正常工作电流长期低于 1 A 并留有安全裕量；对短时突发电流能承受至 40 A，但若长期接近峰值应选用更高规格器件。推荐在实际应用中做热-电仿真与过流测试以验证设备在目标环境下的恢复与寿命表现。

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.
