Sunlord SDNT1005X104J4150HTF NTC热敏电阻产品概述
一、产品定位与核心身份
SDNT1005X104J4150HTF是顺络电子（Sunlord）推出的一款0402封装高精度NTC热敏电阻，属于温度检测类被动元件，核心用于电子系统的温度监测、补偿与控制场景。其命名中：
- “1005”对应英制0402封装（公制1.0mm×0.5mm×0.5mm）；
- “104J”代表25℃时标称阻值100kΩ（10×10⁴Ω），精度±5%（标识“J”）；
- “4150”为25℃/50℃下的B值（温度系数参数）；
- “HTF”隐含高温适配特性，整体适配高密度、宽温域的应用需求。
二、关键电气参数
该型号的电气性能针对温度检测场景做了精准设计，核心参数如下：
参数 数值 说明 标称阻值（25℃） 100kΩ 常用温度检测基准阻值 阻值精度 ±5%（J级） 降低温度计算误差 B值（25℃/50℃） 4150K 中高温度系数，阻值随温度变化敏感 B值精度 ±3% 保证温度系数一致性 最大稳态功率（25℃） 100mW 避免过功率老化 最大稳态电流（25℃） 100μA 低功耗设计，适配小电流系统 耗散系数 1mW/℃ 自热损耗小，减少温度检测误差三、热特性与环境耐受能力
温度检测的核心保障在于热响应与环境适应性，该型号表现如下：
- 工作温度范围：-55℃~+125℃，覆盖工业级、汽车级典型温域（低温端延伸至-55℃，适配极端低温场景）；
- 热时间常数：3s，即阻值变化到最终值63.2%的时间，响应速度较快，满足动态温度监测（如电池实时温控）；
- 自热效应：结合耗散系数与功率限制，实际工作时自热温升可忽略（通常功率远低于100mW），不影响检测精度。
四、封装与物理规格
采用0402表面贴装封装，物理尺寸为1.0mm（长）×0.5mm（宽）×0.5mm（高），具备以下优势：
- 兼容常规SMT贴装设备，自动化生产效率高；
- 小体积大幅节省PCB空间，适配智能手机、可穿戴设备等小型化产品；
- 表面贴装结构无需插件，降低制造成本与装配难度。
五、典型应用场景
基于电气与热特性，该型号广泛应用于多领域：
- 消费电子：智能手机/平板的电池温度监测、CPU/GPU温度补偿；
- 汽车电子：车载中控、车灯、电池管理系统（BMS）的温度检测（宽温域适配汽车环境）；
- 工业控制：小型PLC、传感器模块、电源设备的温度监测与控制；
- 智能家居：空调、热水器等家电的温度传感，提升温控精度。
六、品牌与可靠性保障
顺络电子作为国内被动元件龙头，该型号具备成熟可靠性：
- 采用高稳定性NTC材料，长期使用阻值漂移≤1%（典型值）；
- 封装工艺符合回流焊温度曲线（260℃峰值），耐焊接热；
- 通过ISO9001、IATF16949认证，宽温域测试验证，极端环境下性能稳定。
综上，SDNT1005X104J4150HTF是一款小体积、高精度、宽温域的NTC热敏电阻，适配多场景温度检测需求，是电子系统温控设计的可靠选择。

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.
