Viking光颉AR02BTD4702薄膜贴片电阻产品概述

Viking光颉AR02BTD4702是一款针对高精度、小体积、宽温稳定需求设计的0402封装薄膜贴片电阻,依托光颉成熟的薄膜电阻工艺,在工业控制、精密仪器、消费电子等领域具备广泛适配性,是高密度电路设计的优选元件。

一、产品基本信息

AR02BTD4702隶属于光颉AR02BT系列薄膜电阻,型号编码对应核心参数:

  • AR02BT:系列标识(0402封装高精度薄膜电阻);
  • D:精度等级关联代码(对应±0.1%高精度);
  • 4702:阻值编码(47×10²Ω=47kΩ)。

产品采用贴片式封装,无需穿孔安装,适配SMT自动化生产,可直接焊接于PCB表面,显著节省电路板空间。

二、核心性能参数详解

该电阻的参数针对专业场景优化,关键指标如下:

1. 阻值与精度

阻值固定为47kΩ,精度达**±0.1%**(行业高精度级别),能有效避免因阻值偏差导致的信号失真(如校准电路、放大电路的误差累积)。

2. 功率与工作电压

  • 额定功率:62.5mW(0.0625W),符合0402封装电阻的典型功率需求;
  • 最大工作电压:25V,结合功率公式P=U²/R计算(25²/47000≈13.3mW),实际工作电压远低于功率额定值,可确保长期稳定运行无过热风险。

3. 温度系数(TCR)

温度系数为**±50ppm/℃**,表示环境温度每变化1℃,阻值变化幅度不超过±50ppm(即0.005%)。此参数远优于碳膜电阻(通常±200ppm/℃以上),薄膜电阻的真空镀膜工艺使其阻值随温度波动极小,适合温度变化剧烈的场景。

4. 工作温度范围

覆盖**-55℃~+155℃**,符合工业级宽温要求,可在极端环境(如低温高原、高温车间)下稳定工作,无需额外温度补偿电路。

三、封装与物理特性

AR02BTD4702采用0402封装,标准尺寸为0.04英寸×0.02英寸(约1.0mm×0.5mm),是贴片电阻中体积最小的规格之一,适配高密度PCB设计(如智能手机主板、小型医疗设备)。

封装采用两端电极设计,焊盘与PCB兼容性强,支持回流焊、波峰焊等工艺,焊接后抗振动性能优异(符合IEC 60068-2-6振动测试标准),可承受运输、使用中的机械应力。

四、品牌与可靠性优势

光颉作为全球薄膜电阻核心供应商,AR02BTD4702具备以下可靠性保障:

  • 工艺优势:采用真空溅射镀膜技术,电阻膜层均匀性达行业领先水平,批量生产阻值一致性优于±0.05%;
  • 可靠性测试:通过1000小时负载寿命测试(125℃)、500次温度循环测试(-55℃~+155℃),阻值变化率≤±0.1%;
  • 环保合规:符合RoHS、REACH标准,无铅无卤,适配绿色电子产品设计。

五、典型应用领域

该电阻的性能特点使其适用于多场景:

  1. 精密仪器:万用表、示波器的校准电路,保障测量精度;
  2. 工业控制:PLC模拟量输入/输出模块,宽温稳定运行;
  3. 消费电子:智能手机、蓝牙耳机的信号调理电路,小体积适配紧凑设计;
  4. 通信设备:基站射频前级电路,高精度阻值保障信号质量;
  5. 汽车电子:车载传感器(温度、压力)的信号处理电路,满足部分汽车级宽温需求。

综上,Viking光颉AR02BTD4702薄膜贴片电阻凭借高精度、宽温稳定、小体积等核心优势,可有效提升电子设备的性能与可靠性,是高密度电路设计的高性价比选择。

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
