Viking AR03BTCX3101NA 薄膜贴片电阻产品概述

Viking(光颉)AR03BTCX3101NA是一款0603封装高精度薄膜贴片电阻,专为工业级、精密电子设备的小功率、稳定阻值需求设计,具备高精准度、宽温稳定性、小体积等核心优势,广泛应用于仪器仪表、通信、工业控制等领域。

一、产品基本信息

AR03BTCX3101NA属于光颉AR03系列薄膜电阻,型号编码匹配核心参数:

  • AR03:系列标识(0603封装薄膜电阻专用系列);
  • BTCX:工艺等级(高精度镍铬薄膜工艺);
  • 3101:阻值代码(实际标称阻值为3.1kΩ,符合用户给定规格);
  • NA:环保后缀(无铅RoHS认证封装)。

产品采用0603英制贴片封装(公制1608,尺寸1.6mm×0.8mm),支持表面贴装工艺,适合高密度PCB布局。

二、核心性能参数

该电阻的关键性能参数精准覆盖精密电路需求:

参数项 规格值 核心说明 电阻类型 薄膜电阻 镍铬薄膜工艺(低噪声、抗老化) 标称阻值 3.1kΩ 3100Ω±0.1%精度 精度等级 ±0.1% 工业级高精度(F级) 额定功率 100mW 0603封装典型功率上限 工作电压 75V(最大) 电路允许的最大环境电压 温度系数(TCR) ±25ppm/℃ 温度对阻值影响极小 工作温度范围 -55℃~+155℃ 工业级宽温覆盖 封装形式 0603(1608) 贴片式,适配自动化贴装

三、关键技术特性

1. 高精准度与低温度漂移

±0.1%的精度可满足万用表分压网络、示波器校准电路等对阻值一致性要求极高的场景;±25ppm/℃的TCR意味着:当环境温度从25℃升至125℃(温差100℃),阻值变化仅±0.775Ω,远优于碳膜电阻(通常±500ppm/℃以上),确保电路参数长期稳定。

2. 小体积高密度布局

0603封装尺寸仅1.6mm×0.8mm,可显著压缩PCB空间,适合智能手机电源管理、智能手表传感器接口等便携式设备的高密度设计。

3. 宽温可靠性

-55℃~+155℃的工作范围覆盖工业、汽车辅助电路、航空航天辅助设备的温度需求;薄膜电阻的薄膜层稳定性强,抗湿热、抗老化性能优于碳膜/金属膜电阻。

4. 低噪声特性

镍铬薄膜工艺的电阻噪声系数低(典型值<0.1μV/√Hz),适配医疗监护仪信号放大、音频设备滤波等对噪声敏感的场景。

四、典型应用场景

AR03BTCX3101NA的性能匹配多类精密电子设备,核心应用包括:

  1. 精密仪器仪表:示波器校准电路、万用表分压网络、信号发生器偏置回路;
  2. 通信设备:基站信号调理电路、路由器滤波模块;
  3. 工业控制:PLC传感器信号处理、温度变送器反馈回路;
  4. 便携式电子:智能手机电源管理、智能手表心率传感器接口;
  5. 医疗设备:监护仪心电信号放大、血糖仪滤波电路;
  6. 汽车电子:车载导航信号处理、ADAS辅助电路(宽温场景)。

五、选型与应用注意事项

  1. 功率与电压匹配:
    额定功率100mW,实际应用需满足P=I²R≤100mW或P=V²/R≤100mW。例如:3.1kΩ电阻的最大允许电流约5.7mA,最大允许电压约17.6V;用户标注的75V为电路最大环境电压(需确保流过电阻的电流不超额定值)。

  2. 焊接规范:
    采用回流焊工艺,峰值温度≤260℃,焊接时间≤10秒;避免手工焊接过热损坏薄膜层。

  3. 储存条件:
    未开封产品储存在15~35℃、湿度<60%的干燥环境,开封后建议3个月内使用完毕,防止潮湿导致阻值漂移。

六、品牌与可靠性说明

Viking(光颉)是台湾知名被动元器件厂商,专注电阻、电感研发20余年,AR03系列通过ISO9001、ISO14001认证,部分型号符合AEC-Q200汽车级标准。AR03BTCX3101NA经过温度循环(-55~155℃,1000次)、湿度测试(85℃/85%RH,1000小时)等可靠性验证,可满足工业级应用的长期稳定性需求。

该产品凭借高精准度、宽温稳定、小体积等优势,成为精密电子领域的主流选型之一,适配多类需要稳定阻值的电路设计。

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.

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.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
