NSMD025-30V是台湾陆海电子推出的一款1206封装聚合物自恢复保险丝(PPTC),专为低压电路的过流保护设计,具备可重复使用、快速响应、低功耗等核心优势,广泛适配消费电子、汽车电子及小型工业设备的过载防护需求。
该产品的电气参数经过精准设计,覆盖低压中电流场景的核心防护需求:
电压与电流能力
阻抗与功率特性
NSMD025-30V采用标准1206表面贴装封装(尺寸3.2mm×1.6mm×1.0mm),具备以下特点:
该产品的参数特性使其成为多领域低压过流保护的优选方案:
消费电子领域
汽车电子领域
工业控制领域
NSMD025-30V的工作温度范围覆盖工业级与消费级场景:
为确保防护效果,需注意以下选型与应用细节:
电流匹配
电路正常工作电流需≤Ihold(250mA),过流峰值需≤Imax(100A),避免误触发或器件损坏;若电路电流波动较大,可预留10%-20%的余量。
电压匹配
电路工作电压需≤30V,若使用在更高电压场景(如36V锂电池组),需选择耐压更高的型号。
焊接注意
遵循陆海推荐的焊接温度曲线(回流焊峰值温度260℃±5℃,时间≤10s),避免过热导致器件性能下降;焊接后需检查引脚连接,确保无虚焊、桥接。
恢复条件
过流故障排除后,需等待器件温度降至恢复温度(约100℃) 以下,方可自动恢复至低阻抗状态,无需手动更换或重置。
NSMD025-30V凭借其紧凑的1206封装、精准的电气参数(30V耐压、250mA保持电流)、宽温度范围及可重复使用特性,为低压中电流电路提供可靠的过流防护,适用于消费电子、汽车电子等多个领域,是替代一次性保险丝的高效选择。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
