AR02BTD2002 薄膜贴片电阻产品概述

一、产品基本属性

AR02BTD2002是Viking(光颉) 推出的一款精密薄膜贴片电阻,核心定位为小封装、高精度、宽温稳定型 电子元件,适配各类对阻值精度、环境适应性要求较高的电路场景。其基础属性如下:

  • 品牌:Viking(光颉)
  • 产品型号:AR02BTD2002
  • 电阻类型:薄膜贴片电阻(非厚膜/合金电阻)
  • 封装规格:0402(英制,对应公制尺寸:1.0mm×0.5mm×0.35mm)
  • 环保认证:符合RoHS无铅要求

二、核心技术参数详解

该电阻的关键参数均针对精密电路设计,具体性能可从以下维度解析:

1. 阻值与精度

标称阻值为20kΩ,精度等级达**±0.1%** —— 即实际阻值范围为19980Ω20020Ω,偏差仅20Ω,远优于普通厚膜电阻(±1%±5%),可满足信号调理、分压校准等场景的精准度需求。

2. 功率与电压承载

额定功率为62.5mW,最大工作电压25V —— 结合欧姆定律计算,最大工作电流为1.25mA(25V/20kΩ),功率消耗严格控制在额定值内,避免小封装电阻因过功率导致的性能衰减。

3. 温度特性

  • 温度系数(TCR):±50ppm/℃ —— 每变化1℃,阻值变化比例为50×10⁻⁶,温度变化100℃时阻值仅偏移±0.5%,稳定性显著优于普通电阻(厚膜电阻TCR通常≥±100ppm/℃);
  • 工作温度范围:-55℃~+155℃ —— 覆盖工业级、部分汽车级环境(如高温车间、户外设备),极端温度下仍保持性能稳定。

三、封装与工艺特点

1. 0402小封装优势

0402封装体积仅为0805封装的1/4,厚度约0.35mm,适合高密度PCB设计(如智能手机、智能穿戴、小型医疗仪器),可有效降低设备体积与重量,提升集成度。

2. 薄膜电阻工艺核心

采用真空溅射镍铬(NiCr)薄膜 技术,相比厚膜电阻的丝网印刷工艺:

  • 薄膜层厚度更均匀(10~100nm),激光微调精度更高,确保±0.1%精度一致性;
  • 阻值长期漂移小(通常≤0.05%/1000小时),可靠性优于厚膜电阻;
  • 陶瓷基片封装抗冲击、抗振动,适合工业现场环境。

3. 光颉工艺保障

Viking作为专业电阻厂商,该产品采用双激光微调技术 控制阻值精度,同时封装过程中严格管控焊接性能(可通过回流焊、波峰焊),减少虚焊风险。

四、典型应用场景

AR02BTD2002的性能匹配多类精密电路需求,核心应用场景包括:

1. 医疗电子设备

如监护仪生理信号放大电路、血糖仪血糖浓度检测电路 —— 需高精度电阻保证信号采集准确性,宽温范围适应医疗设备的环境变化(如手术室、病房温度波动)。

2. 通信设备

如射频前端滤波电路、基站信号处理模块 —— 0402小封装适合高密度PCB,低TCR避免温度变化导致的信号频率偏移,提升通信稳定性。

3. 工业控制

如传感器信号调理电路、PLC模拟量输入模块 —— 宽温范围(-55~+155℃)适应工业现场极端温度,高精度保证控制精度(如温度传感器校准)。

4. 精密仪器

如示波器垂直放大电路、信号发生器输出校准电路 —— ±0.1%精度满足仪器计量校准需求,确保测量结果准确性。

五、性能优势总结

AR02BTD2002的核心竞争力可归纳为:

  1. 高精度:±0.1%阻值精度,满足精密电路参数一致性;
  2. 高稳定:±50ppm/℃低TCR,宽温范围内阻值漂移极小;
  3. 小型化:0402封装适配高密度、便携式设备设计;
  4. 宽温可靠:-55~+155℃工作范围,适应恶劣环境;
  5. 品牌保障:Viking光颉的专业工艺,确保产品可靠性与一致性。

该电阻是医疗、通信、工业等领域精密电路的高性价比选择,可有效提升电路性能与设备稳定性。

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.
