NSMD100-16V 产品概述
一、产品简介
NSMD100-16V 是台湾陆海（Luhai）推出的自恢复保险丝（Polymeric PTC），封装尺寸为 1206，额定保持电流 1A、额定电压 16V。该器件在过流情况下会迅速增阻限制电流，故障消除后随着温度下降恢复低阻状态，适用于保护小型电子设备的供电线路与负载。
二、主要电气参数
- 最大耐压（Vmax）：16V
- 最大承受电流（Imax）：100A（瞬态浪涌电流能力，非连续工作电流）
- 保持电流（Ihold）：1.0A（在规定温度下长时间不发生跳闸）
- 跳闸电流（Itrip）：1.8A（典型启动跳闸门限）
- 消耗功率（Pd）：600mW（允许的功耗，注意与环境温度相关）
- 初始态阻值（Rmin）：55mΩ（初始低阻抗以降低压降）
- 跳断后阻值（R1max）：270mΩ（保护动作后限制电流）
- 工作温度范围：-40℃ ~ +85℃
三、特性与优势
- 自恢复：过流后自动限流并在故障清除后恢复，无需更换，降低维修成本。
- 低初始阻抗：55mΩ 起，保证正常工作时压降和功耗较小，适合1A 级电源轨。
- 抗浪涌能力：可承受高达 100A 的瞬态浪涌，适用于存在启动电流或短时脉冲电流的电路。
- 宽温度适应性：-40℃ 至 +85℃ 的工作范围，可用于工业及消费类设备。
- 小型封装：1206 适合 SMD 自动贴装，便于高密度 PCB 布局。
四、典型应用场景
- USB/外设电源保护（5V/12V 低压系统，需满足 16V 最大耐压）。
- 消费电子（平板、笔记本周边、智能家居模块）短路/过流防护。
- 通信设备和工业控制信号电源保护（需注意环境温升对 Ihold 的影响）。
- 电池供电设备的局部线路保护（非主电池过放或热失控防护）。
五、封装与可靠性
1206 表面贴装封装支持回流焊工艺，适配常规 SMT 生产线。器件在反复过流恢复周期中具有稳定的限流性能，但长期高温或频繁高电流冲击会影响寿命与跳闸特性，建议在设计时留有裕量并按厂家提供的时-电特性曲线评估。
六、选型与使用注意
- 核对时间-电流特性曲线：根据电路可能的持续过流与冲击电流选择合适的 Ihold/Itrip 余量。
- 留意环境温度影响：高温会降低保持电流，可能导致误触发，需要适当降额设计。
- 布局建议：将 NSMD100-16V 放置于需要保护的电源入口或靠近被保护元件，避免与强热源共置，保证散热。
- 不适合用作断路器或过压保护，且不作为一次性熔断保险丝替代品。
七、结语
NSMD100-16V 以其小型化、可自恢复以及良好的浪涌承受力，在 1A 级保护应用中表现出色。选用时应结合具体工作电压、环境温度和电流波形，参考厂商的完整规范与时-电曲线，以确保长期可靠性和系统安全。

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.
