SDNT2012X473F4150FTF 产品概述
一、产品简介
SDNT2012X473F4150FTF 是顺络（Sunlord）推出的一款高精度表面贴装型 NTC 热敏电阻，封装为 0805（国际尺寸 2012），标称阻值 47kΩ，阻值公差 ±1%，B 值（25℃/50℃）为 4150K（±1%）。器件适合对温度敏感度与稳定性要求较高的便携消费、测温与温度补偿场合。
二、主要参数（主要指标）
- 阻值：47 kΩ ±1%
- B 值（25℃/50℃）：4150 K ±1%
- 功率额定：200 mW
- 最大稳态电流（25℃）：200 μA
- 工作温度范围：-55℃ ~ +125℃
- 耗散系数（热耗散常数）：2 mW/℃
- 热时间常数：5 s
- 尺寸（长×宽×高）：2.00 × 1.25 × 0.85 mm
- 封装：0805（2012 英制）
三、性能与特点
- 高精度阻值与 B 值（±1%），温度测量与补偿精度高；
- 体积小、易贴装，兼容自动贴片与回流焊工艺；
- 低自热、耗散系数小，有利于减小测量误差；
- 宽温工作范围、可靠性高，适用于工业与消费类产品。
示例计算：在 25℃ 下按最大稳态电流 200 μA 计算，功耗约为 P = I^2R ≈1.88 mW，对应稳态升温约 ΔT = P / (2 mW/℃) ≈ 0.94℃（可见自热影响微小）。
四、应用场景
- 便携终端与智能硬件温度监测；
- 电池管理与充放电温度保护；
- 温度补偿电路（如时钟、电源、传感器前端）；
- 家电与工业控制中的局部温度检测。
五、使用建议与注意事项
- 测量时尽量使用小电流源，避免额外自热影响测量精度；
- 布局时考虑良好热耦合点，避免大面积铜箔引起的热扩散误差；
- 回流焊需遵循无铅回流焊曲线，避免长时间高温暴露与机械应力；
- 储存条件应干燥、防潮，避免长时间受潮和挤压导致性能改变。
本产品适用于对温度响应速度、精度及稳定性有较高要求的电子系统，提供可靠的温度测量与补偿解决方案。若需完整数据手册、S-参数或样品支持，请联系顺络官方渠道获取详细资料与认证信息。

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.
