NTC10D-5 产品概述
一、主要参数
- 阻值（25℃）：10 Ω
- B值（25℃/50℃）：2700 K
- 最大稳态电流（25℃）：700 mA
- 工作温度范围：-40 ℃ ~ +150 ℃
- 耗散系数（功率-温升系数）：6 mW/℃
- 热时间常数：20 s
- 引脚间距（P）：5 mm，插件封装
- 品牌：RUILON（瑞隆源）
用途描述：NTC 热敏电阻，常用于浪涌吸收、进/过流限制、灭弧/防打火及低功耗保护电阻等场合。
二、产品特性
- 低冷阻值（10 Ω），能在通电瞬间有效限制浪涌电流，适用于电源输入、整流桥后及电容充电回路。
- B 值 2700 K 表征了良好的温度-电阻特性，温度敏感度高，适合检测与温度补偿场景。
- 宽工作温度与较高最大稳态电流（700 mA）满足工业类或商用电源的使用要求。
- 耗散系数 6 mW/℃ 与热时间常数 20 s，表明器件对环境温升响应中等，便于热设计与散热控制。
- 插件 P=5mm 便于手工焊接与穿孔 PCB 固定，可靠性高。
三、工作原理与典型公式
NTC（负温度系数）热敏电阻随温度升高电阻下降。常用近似关系： R(T) = R25 · exp[B · (1/T - 1/T0)] 其中 R25 为 25 ℃ 时阻值（10 Ω），B 为 2700 K，T 与 T0 以开尔文计。该公式可用于估算不同温度下的阻值与热平衡状态。
四、典型应用场景
- 电源进线的浪涌电流限制（开机充电电流抑制）
- 开关电源与变压器继电器的灭弧/吸弧，降低接触器触点打火概率
- LED 驱动、电机驱动与电容充放电电路的过流保护
- 电池包充电限流与温度补偿场合
- 作为低功耗保护电阻或分流检测元件
五、选型与使用注意
- 根据最大通流与持续功耗评估：700 mA 为最大稳态电流，长时间运行接近此值需注意器件自热与环境温度；耗散系数 6 mW/℃ 可用于估算在一定环境温度下的稳态功耗与温升。
- 对浪涌能量与重复脉冲要做验证，NTC 在多次高能冲击下电阻可能发生不可逆变化，必要时选择带有额外熔断或并联限流方案。
- 焊接建议：遵循插件元件常规焊接温度与时间规范，避免长时间高温烘烤导致特性漂移。安装时注意留有散热空间，避免紧贴大面积金属散热体造成热耦合误差。
- 环境与可靠性：在高温或长期高功耗条件下应做加速老化与寿命评估；-40 ~ +150 ℃ 的额定范围要求在极端环境下验证性能稳定性。
六、包装与订购
型号：NTC10D-5（RUILON/瑞隆源）
封装形式：插件，P=5mm。具体包装、最小订单量、样品及合规证书（如 RoHS）可联系供应商或代理获取。若需电气曲线、热平衡图或样品测试报告，请提供应用场景与测试条件以便定制化支持。

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.
