AR03BTCX2492 薄膜电阻产品概述

一、产品定位与核心身份

AR03BTCX2492是Viking(光颉)推出的高精度小功率薄膜电阻,属于该品牌精密电阻系列中的核心型号,专为对阻值精度、温度稳定性要求严苛的电子电路设计,可覆盖工业控制、汽车电子、精密测量等多领域的高要求应用场景。

二、关键参数深度解析

该型号的参数精准匹配高可靠场景需求,具体如下:

  1. 电阻类型:采用镍铬薄膜技术(光颉主流精密电阻工艺),相比碳膜、金属氧化膜电阻,具备更低噪声、更高温度稳定性;
  2. 阻值与精度:标称阻值24.9kΩ(阻值代码“2492”对应249×10²=24900Ω),精度±0.1%——这一等级可满足99.9%以上精密电路的偏差要求,避免常规电阻因精度不足导致的信号失真;
  3. 功率等级:100mW小功率设计,适配低功耗信号调理、分压限流等场景,同时支持高密度PCB集成;
  4. 温度系数(TCR):±25ppm/℃——指温度每变化1℃,阻值变化量为标称值的25×10⁻⁶。以100℃温度变化为例,该电阻阻值漂移仅约62Ω,远低于常规电阻的漂移量,确保宽温下电路性能稳定;
  5. 工作温度范围:-55℃+155℃,覆盖工业级(-40+85℃)、汽车级(-40~+125℃)甚至更高温场景,适应极端环境下的长期运行。

三、核心特性与优势

  1. 高精度一致性:采用激光微调工艺,单批次内阻值偏差控制在±0.1%以内,长期稳定性优异,避免批次差异导致的电路调试问题;
  2. 低温度漂移:±25ppm/℃的TCR是核心优势,可有效抑制宽温环境下的阻值变化,适合户外设备、高温工业设备等场景;
  3. 小体积高集成度:结合0402(AR03封装代码)小型封装,可满足高密度PCB设计需求,尤其适合便携式设备、小型化仪器;
  4. 低噪声特性:镍铬薄膜电阻的噪声系数远低于碳膜电阻,可降低信号链中的噪声干扰,提升测量、通信电路的信噪比;
  5. 环保与可靠性:符合RoHS、REACH等环保标准,同时具备抗振动(≥10G)、抗冲击(≥50G)性能,满足工业、汽车领域的可靠性要求。

四、典型应用场景

  1. 精密测量仪器:数字万用表、示波器、频谱分析仪的信号放大、分压电路,确保测量精度达到0.1%级;
  2. 工业控制电路:PLC模块、传感器信号调理(压力、温度传感器放大)、电机驱动限流,适应工业现场宽温与振动环境;
  3. 汽车电子:车载传感器(胎压监测、氧传感器)信号处理、车身控制模块(BCM)电源分压,符合汽车级可靠性要求;
  4. 通信设备:基站、路由器的信号滤波、阻抗匹配电路,低噪声特性提升通信质量;
  5. 医疗电子:监护仪、输液泵的信号采集电路,高精度阻值确保医疗数据准确性。

五、品牌背书与品质保障

Viking(光颉)作为全球领先的被动元件制造商,拥有30余年精密电阻研发生产经验,产品通过ISO9001、IATF16949(汽车行业)、AEC-Q200(汽车电子)等权威认证。AR03BTCX2492继承品牌“高精度+高可靠性”基因,从高纯度镍铬薄膜原材料选型到激光微调、真空封装工艺,均经过严格管控,确保每只电阻的性能一致性与长期稳定性。

该型号以高性价比平衡了精度、稳定性与成本,是中高端电子设备中精密电阻选型的优选方案。

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
