AR02BTC2002 薄膜贴片电阻产品概述

一、产品定位与核心特征

AR02BTC2002是Viking(光颉)推出的高精度薄膜贴片电阻,聚焦对阻值精度、温度稳定性要求较高的电子电路设计,同时兼顾小体积与低功耗需求。其核心特征可概括为:

  • 高精度:阻值精度达±0.1%,满足精密信号处理、测量场景;
  • 宽温稳定:温度系数仅±25ppm/℃,环境温度变化对阻值影响极小;
  • 小封装适配:0402(1005公制)封装,适合高密度PCB布局;
  • 低功耗设计:额定功率62.5mW,适配便携、低功耗电子设备。

二、基础参数详解

该电阻关键参数经严格校准,具体如下:

  1. 阻值与精度:标称阻值20kΩ,精度±0.1%(实际偏差≤±20Ω),远高于普通电阻的±1%/±5%精度,可精准实现分压、电流采样等功能;
  2. 功率与电压:额定功率62.5mW,工作电压25V,低功耗电路中无需额外降额设计,简化电路复杂度;
  3. 温度特性:温度系数(TCR)±25ppm/℃,即温度每变1℃,阻值变化0.5Ω(20kΩ×25×10⁻⁶),100℃温差下偏差仅5Ω,远小于精度允许范围;
  4. 工作温度范围:-55℃至+155℃,覆盖工业级、汽车级等严苛环境;
  5. 封装尺寸:0402英制封装(公制1005,尺寸1.0mm×0.5mm×0.45mm),体积小巧,适配便携设备高密度布局。

三、封装与工艺优势

  1. 薄膜工艺提升性能:采用薄膜电阻工艺(区别于厚膜电阻的丝网印刷),通过真空沉积制备电阻层,相比厚膜电阻具有:
    • 更高精度与温度稳定性;
    • 更低噪声(适合微弱信号处理);
    • 长期阻值漂移更小;
  2. 0402封装适配性:
    • 小体积:仅为0603封装的1/4,大幅节省PCB空间;
    • 自动化贴装:兼容SMT生产线,提高生产效率与一致性;
    • 抗振动性:结构紧凑,可承受一定振动冲击,适合汽车、工业设备场景。

四、典型应用场景

AR02BTC2002的参数特性适配多种高精度、小体积电路:

  1. 精密测量仪器:示波器、信号发生器、万用表的信号调理(分压、滤波、基准源);
  2. 便携电子设备:智能手机、智能手表、蓝牙耳机的电源管理、传感器信号处理;
  3. 工业控制电路:PLC、传感器节点的信号放大、采样(宽温域适配工业现场);
  4. 汽车电子:车载中控、胎压监测/温度传感器的信号处理(满足汽车级温度要求);
  5. 低功耗物联网:智能门锁、环境监测传感器的低功耗电路设计。

五、可靠性与环境适应性

该产品经多重测试验证可靠性:

  • 宽温域可靠性:-55℃至+155℃范围内,阻值变化率符合工业级标准;
  • 长期稳定性:薄膜工艺确保长期使用中阻值漂移极小,适合长期运行设备;
  • 抗环境干扰:封装采用耐湿、耐蚀材料,适应湿度、盐雾等复杂环境;
  • 振动与冲击耐受:通过10-2000Hz振动、1000m/s²冲击测试,满足移动/工业设备需求。

六、总结

AR02BTC2002以高精度、宽温稳定、小体积、低功耗为核心优势,精准匹配精密电子、工业控制、汽车电子等领域设计需求。无论是便携设备的高密度布局,还是工业/汽车场景的严苛环境,该电阻均能提供可靠性能,是高性价比的高精度薄膜贴片电阻选择。

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
