AR03DTC6402N 薄膜贴片电阻产品概述
AR03DTC6402N是Viking（光颉） 推出的一款0603封装薄膜贴片电阻，针对高精度、小体积、宽温稳定的应用需求设计，是工业控制、通信设备、消费电子等领域信号调理电路的理想选择。
一、产品核心定位与应用场景
该电阻聚焦小功率高精度场景，核心解决“小体积下阻值稳定、精度可控”的需求——相比普通碳膜电阻，薄膜工艺带来更高精度与温度稳定性；0603封装则适配高密度PCB设计，满足便携设备、紧凑型模块的空间限制。典型应用覆盖三类场景：
- 对阻值误差敏感的信号调理（如ADC参考分压、传感器信号放大）；
- 宽温环境下的稳定工作（如工业现场、车载低温/高温场景）；
- 高密度PCB的小空间布局（如智能手机主板、路由器射频模块）。
二、关键参数详解
AR03DTC6402N的参数围绕“精度、稳定性、适配性”设计，核心参数及意义如下：
参数 数值 关键说明 电阻类型 薄膜电阻 采用真空溅射工艺，阻值一致性优于碳膜/金属膜，长期漂移小 阻值 64kΩ（6402） 代码“6402”对应“64×10²Ω”，满足多数分压/限流电路的阻值需求 精度 ±0.5% 阻值误差控制在64kΩ±320Ω，适合对精度要求高于±1%的电路（如ADC基准分压） 额定功率 62.5mW 适配0603封装的散热能力，正常工作下不会因功率过载导致阻值漂移或损坏 额定工作电压 50V 最大连续工作电压，需避免超过此值（否则可能击穿或性能下降） 温度系数（TCR） ±25ppm/℃ 温度每变化1℃，阻值变化≤25×10⁻⁶；100℃温差下阻值变化仅±160Ω，稳定性优异 工作温度范围 -55℃~+155℃ 覆盖工业级宽温，可在极端高低温环境下长期可靠工作三、封装与工艺优势
1. 0603封装：小体积高密度
英制0603封装（公制1608）尺寸为1.6mm×0.8mm，厚度约0.45mm，相比0805封装体积缩小约60%，适合便携设备（如智能手表、蓝牙耳机）的高密度PCB布局，同时兼容自动贴装（SMT）工艺，提升量产效率。
2. 薄膜工艺：高精度低漂移
光颉采用高精度真空溅射薄膜工艺，在陶瓷基底上沉积镍铬等金属薄膜，相比传统碳膜：
- 精度提升23倍（±0.5% vs 碳膜±1%±5%）；
- 温度系数降低（±25ppm/℃ vs 碳膜±200ppm/℃以上）；
- 长期阻值漂移≤0.1%/1000小时，适合长期稳定工作的工业场景。
四、可靠性与环境适应性
AR03DTC6402N通过多项可靠性测试，满足工业级应用要求：
- 温度循环测试：-55℃~+155℃循环1000次，阻值变化≤0.2%；
- 湿度测试：85℃/85%RH环境下1000小时，阻值变化≤0.3%；
- 功率负载测试：额定功率下连续工作1000小时，阻值漂移≤0.1%；
- 符合IPC/J-STD-002标准，兼容无铅回流焊工艺，适合RoHS环保要求。
五、典型应用领域
- 工业控制：PLC模块、传感器接口电路的分压/限流（如温度传感器信号放大）；
- 通信设备：基站射频前端、路由器信号滤波电路的高精度匹配电阻；
- 消费电子：智能手机音频电路、智能手表传感器模块的信号调理；
- 汽车电子：车载信息娱乐系统的小信号电路（如中控屏触摸感应模块）。
总结：AR03DTC6402N以“小体积+高精度+宽温稳定”为核心优势，适配多领域的小功率信号电路需求，是光颉薄膜电阻系列中针对中端高精度场景的代表性产品。
Request for quote
Send RFQ
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.
