NTC2.5D-15 产品概述
一、产品简介
NTC2.5D-15 是 RUILON(瑞隆源) 推出的直插式热敏电阻，型号标识清晰、校验通过！本器件以低阻值、快速热响应和耐高温特性为主要卖点，适用于需要限制浪涌电流或进行温度补偿的场合。封装为插件式，间距 P=7.5mm，便于手工或波峰/回流焊装配。
二、主要电气与热学参数
- 标称功率：3.5 W（稳态）
- 阻值：2.5 Ω
- 电阻精度：±20%
- B 值（25℃/50℃、25℃/75℃、25℃/85℃、25℃/100℃）：2600 K（B 值精度 ±10%）
- 最大稳态电流（25℃）：8 A
- 耗散系数：18 mW/℃（热耗散常数，表征器件在环境中的散热能力）
- 热时间常数：1.43 min（约 86 秒，表明器件达到热平衡所需时间）
- 工作温度范围：-40℃ 到 +200℃
三、机械尺寸与封装
- 直径（φD）：17.5 mm
- 引脚间距：7.5 mm（插件，便于标准 PCB 开孔和安装）
- 封装形式：插件（P=7.5mm）
四、典型应用场景
- 浪涌电流抑制：在电源、开关电源和大型电机启动回路中，用于限制启动瞬间的大电流，保护整机元件。
- 温度补偿与检测：利用稳定的 B 值用于温度补偿电路或温度测量场合，特别是需要在高温环境下工作的系统。
- 充电与照明设备：用于充电器、LED 驱动等需要控制浪涌或稳定工作温度的器件中。
五、使用与安装要点
- 避免超过最大稳态电流 8A 与额定功率 3.5W，以免引起过热损坏。
- 器件耗散系数为 18 mW/℃，在高功率应用中需考虑必要的散热措施或留有足够的环境空间。
- 热时间常数约 86 秒，短时冲击和稳态温升需区别对待，评估电路中瞬态与稳态温度。
- 插件封装便于焊接，但建议按照生产工艺控制焊接温度与时间，避免长期高温造成材料老化。
- 工作温度覆盖 -40℃ 至 +200℃，可适用于高温工况，但长时间在极端温度下工作需考虑寿命影响。
六、总结
NTC2.5D-15 结合低阻值、可观的稳态功率和较宽的工作温度范围，适合用于浪涌抑制、温度补偿与高温环境下的温度检测场合。凭借 RUILON（瑞隆源）可靠的制造工艺与插件封装设计，本型号在实装与维护上具备良好的兼容性与稳定性。校验通过，推荐在电源保护与热敏控制类应用中优先评估与应用。

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.
