AR03BTCX2403 薄膜贴片电阻产品概述

一、产品核心身份与品牌背景

AR03BTCX2403是Viking(光颉) 推出的精密薄膜贴片电阻,属于光颉被动元件产品线中的高端型号。光颉作为全球知名的被动元件制造商,专注于薄膜电阻、电感等器件的研发与生产,其产品以高稳定性、低噪声、宽温适应性为核心优势,广泛应用于工业控制、医疗设备、通信射频等对精度要求严苛的领域。该型号针对小体积、高精度场景优化,是高密度PCB设计的理想选择。

二、关键性能参数与设计亮点

1. 阻值与精度

核心阻值为240kΩ,精度等级达**±0.1%** —— 这一精度远高于普通碳膜电阻(通常±5%~±1%),可满足电桥电路、精密分压网络、传感器校准等需要阻值精准匹配的场景,避免因阻值偏差导致的信号失真或测量误差。

2. 功率与功耗

额定功率为100mW(0.1W),适配小信号放大、信号调理、低功耗电源分压等场景(如便携式医疗设备的传感器供电电路)。需注意:实际使用中需结合环境温度(高温下需降额),避免超过功率极限导致器件失效。

3. 温度系数与稳定性

温度系数(TCR)为**±25ppm/℃,即温度每变化1℃,阻值变化量不超过:
$$240kΩ \times 25 \times 10^{-6} = 6Ω$$
这一参数体现了器件的
宽温稳定性**——即使在极端温度下(如-55℃~+155℃),阻值漂移极小,适合工业现场、车载电子等宽温环境。

4. 薄膜电阻的技术优势

相比碳膜、金属膜电阻,薄膜电阻采用真空溅射+光刻工艺制备电阻层,具有三大核心优势:

  • 低噪声:典型噪声系数<10nV/√Hz,适合音频设备、精密测量仪器等对噪声敏感的场景;
  • 高频特性优异:截止频率可达GHz级,适配射频前端滤波、中频放大等电路;
  • 长期稳定性:老化率低(通常<0.05%/1000小时),适合长寿命应用(如医疗设备、工业控制器)。

三、封装与物理特性

1. 封装规格

采用0603封装(英制命名,公制对应1608),具体尺寸为:

  • 长度:1.6mm ±0.15mm
  • 宽度:0.8mm ±0.15mm
  • 厚度:0.4mm ±0.05mm

小体积设计可显著降低PCB占用面积,适配智能手机、智能穿戴、高密度通信模块等对空间要求严苛的产品。

2. 端接与焊接兼容性

电阻端接采用镍锡(Sn/Ni)镀层,符合RoHS 2.0环保标准,可兼容回流焊、波峰焊等SMT(表面贴装)工艺,焊接可靠性高,适合批量生产。

四、典型应用场景

AR03BTCX2403的性能特点使其适配以下场景:

  1. 工业控制:传感器信号调理(压力/温度传感器分压校准)、PLC输入输出接口、伺服电机驱动电路;
  2. 医疗设备:心电图机信号放大、血糖监测仪校准电路、呼吸机压力传感器接口;
  3. 通信射频:5G基站射频前端滤波网络、WiFi模块中频放大电路、蓝牙设备偏置电阻;
  4. 消费电子:高端音频解码器(DAC)信号路径、便携式电源管理模块(PMU)分压电阻、智能手表传感器电路。

五、可靠性与环境适应性

  • 工作温度范围:-55℃~+155℃,覆盖工业级宽温需求,可在高温车间、寒冷户外等极端环境下稳定工作;
  • 可靠性测试:通过光颉内部可靠性验证(高温存储、温度循环、湿度老化、机械振动等),失效率符合MIL-STD-202标准;
  • 环保合规:无铅、无镉,符合RoHS 2.0、REACH、WEEE等全球环保指令,满足欧美、日本等市场准入要求。

综上,AR03BTCX2403凭借高精度、宽温稳定、小体积等核心优势,成为精密电子领域的高性价比选择,尤其适合对阻值精度和环境适应性要求严苛的应用场景。

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
