SDNT0603C683F4250FTF NTC热敏电阻产品概述

SDNT0603C683F4250FTF是顺络电子(Sunlord)推出的一款高精度贴片式NTC热敏电阻,专为小型化、高可靠的温度传感场景设计,兼具小体积、宽温域、高灵敏度等核心优势,可广泛应用于消费电子、汽车电子、工业控制等领域。

一、产品核心身份与定位

该型号属于顺络NTC热敏电阻系列中的0201封装(公制0603) 产品,以负温度系数(NTC) 为核心特性——温度升高时阻值呈非线性降低,可通过阻值变化精准反映环境温度。其定位为紧凑型高精度温度传感元件,适配对空间占用敏感、温度测量精度要求较高的电子设备,是替代传统体积较大热敏电阻的理想选择。

二、关键电气与性能参数解析

产品核心参数围绕温度传感的精度、灵敏度与可靠性设计,具体如下:

  1. 阻值与精度:常温(25℃)下标称阻值为68kΩ(对应3位编码“683”,即68×10³Ω),阻值精度为±1%,在常温及典型工作温度范围内,阻值偏差极小,可满足精密温度测量需求;
  2. B值与灵敏度:以25℃/50℃为基准的B值为4250K,B值直接反映热敏电阻的温度灵敏度——B值越高,相同温度变化引起的阻值变化越显著,该参数确保了产品在宽温域内的温度响应一致性;
  3. 功率与功耗限制:最大额定功率为100mW,适用于低功耗电路设计,避免因功率过载导致性能衰减或损坏;
  4. 工作温度范围:覆盖-55℃至+125℃的宽温域,可适应极端环境(如低温户外、高温工业场景),满足工业级、汽车级部分应用的温度要求。

三、封装与物理特性

产品采用0201贴片封装(尺寸约1.6mm×0.8mm×0.5mm),具有以下物理优势:

  1. 超小体积:相比0402、0603等封装,体积缩小约40%,可显著降低设备内部空间占用,适配可穿戴设备、智能手机等小型化终端;
  2. 自动化适配:贴片式封装兼容主流SMT贴装设备,支持高速批量生产,降低人工成本与贴装误差;
  3. 抗振动性能:表面贴装结构牢固,抗振动、抗冲击能力强,适合移动设备(如汽车、无人机)等振动环境。

四、典型应用场景

基于其参数特性,SDNT0603C683F4250FTF可覆盖以下核心场景:

  1. 消费电子:智能手机/平板的电池温度监测、CPU/GPU过热保护,可穿戴设备(智能手环、手表)的人体温度传感;
  2. 汽车电子:车载小型传感器模块(如胎压监测、环境传感器)的温度补偿,车载充电设备的过温保护;
  3. 工业控制:小型仪器仪表(如温湿度传感器、数据采集器)的温度测量,工业电源模块的过热监控;
  4. 通信设备:5G基站小型射频模块的温度补偿,路由器/交换机的内部温度监测。

五、可靠性与品牌保障

顺络电子作为国内被动元件龙头企业,该产品具备可靠的质量体系:

  1. 宽温域可靠性:在-55℃至+125℃范围内,经过多次温度循环测试,阻值变化率控制在±0.5%以内,确保长期使用稳定性;
  2. 一致性保障:B值精度±1%、阻值精度±1%,批量产品的性能一致性优异,适配大规模量产需求;
  3. 环境适应性:符合RoHS、REACH等环保标准,同时具备抗盐雾、耐湿热等特性,可适应复杂应用环境。

六、应用注意事项

为确保产品性能稳定,应用时需注意以下要点:

  1. 阻值匹配:需与电路中的分压电阻、运放电路等匹配,避免阻值偏差影响温度测量精度;
  2. 功率限制:实际功耗需控制在100mW以内,可通过串联限流电阻或降低工作电压实现;
  3. 温度补偿:NTC阻值变化为非线性,实际应用中建议配合微控制器(MCU)进行线性化补偿,提高温度测量精度;
  4. 贴装工艺:0201封装对贴装精度要求较高,需使用专用贴装吸嘴,避免贴装偏移或损伤。

综上,SDNT0603C683F4250FTF以小体积、高精度、宽温域为核心优势,适配多领域温度传感需求,是顺络电子针对紧凑型电子设备推出的高性价比NTC热敏电阻产品。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
