NSMD010 产品概述
一、产品简介
NSMD010 是 KUU 品牌的一款 1206 封装自恢复熔断器（又称聚合物自恢复保险丝、PTC 熔断器），标称工作电压 30V，保持电流 0.1A。该器件在过流时通过内部材料的正温度系数特性迅速上升电阻以限制电流，故障消除后能自动冷却复位，适用于需要反复保护的小型电子设备与模块。
二、主要电气参数
- 耐压（Vmax）：30 V
- 保持电流（Ihold）：100 mA（典型，温度/环境有关）
- 跳闸电流（Itrip）：250 mA（触发过流保护的典型值）
- 最大短时冲击电流（Imax）：10 A（可承受短时脉冲）
- 功耗（Pd）：400 mW（额定功耗/温升评估依据）
- 初始态阻值（Rmin）：1.4 Ω
- 跳断后阻值（R1max）：15 Ω（限制电流后的高阻态）
- 动作时间：1.2 s（在规定过流条件下触发时间）
- 工作温度范围：-40 ℃ ~ +85 ℃
三、封装与机械特性
- 封装：1206（3.4 mm × 1.8 mm × 1.2 mm）
- 适合表面贴装（SMT）工艺，体积小、重量轻，便于高密度 PCB 布局。
四、典型应用场景
- 手机或平板配件、USB/充电线路过流保护
- 电池管理系统（辅助保护）、移动电源保护线路
- 消费类电子、物联网模块、嵌入式控制板的输入侧防护
- LED 驱动与外围电路短路/过流保护
五、使用与设计建议
- 在 PCB 布局时为器件留足焊盘和热沉空间，确保散热均匀；建议遵循 1206 封装的厂家推荐焊盘尺寸与回流工艺。
- 考虑环境温度对保持电流/跳闸电流的影响，高温环境下保持电流会降低，应适当留有裕量。
- 该器件适合保护可重复故障场景，不用于要求一次性熔断的场合（一次性熔断器）。
- 在高脉冲或频繁大电流冲击的应用中，需验证实际寿命与耐久性，必要时采用并联或更大规格器件。
六、注意事项
- 工作电压请勿超过 30 V；长期接近额定功率工作会导致温升和性能退化。
- 选型时应以最大工作环境温度、可能的浪涌电流以及系统允许的动作时间为准，确保 Ihold 与 Itrip 满足系统需求。
- 出厂前后请注意防静电与机械冲击，避免影响器件特性。
NSMD010 以其小封装、自恢复特性和明确的电气指标，适合需要稳定、可复位过流保护的紧凑型电子产品和模块化电路保护方案。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
