Viking光颉AR03BTCX1200薄膜贴片电阻产品概述

一、核心参数规格详解

Viking光颉AR03BTCX1200为薄膜贴片电阻,核心参数精准匹配精密电路需求,关键指标如下:

  • 阻值:120Ω,精度±0.1%(即阻值波动范围仅±0.12Ω);
  • 功率:额定功率100mW,满足低功耗电路的功率承载;
  • 额定电压:75V(实际使用需同时满足「电压≤75V」「功率≤100mW」,取较严格限制);
  • 温度系数:±25ppm/℃(温度每变化1℃,阻值变化约0.003Ω);
  • 封装:0603(英制0.06″×0.03″,公制1.6mm×0.8mm),体积小巧;
  • 工作温度:-55℃~+155℃,覆盖宽温环境需求。

二、封装与功率特性适配

0603封装是贴片电阻的主流小尺寸规格,适配高密度PCB设计(如智能手机、小型通信模块),可显著提升电路集成度;100mW额定功率虽为小功率,但针对其120Ω阻值,实际应用中可覆盖「小信号调理、精密分压」等场景(如传感器输出信号的放大前分压),无需担心功率过载。

需注意:实际使用时需根据电路实际电压/电流计算功率,确保不超过100mW阈值。

三、高精度与宽温稳定性

该电阻的**±0.1%精度**是核心优势之一,远高于普通碳膜(±5%)、金属膜(±1%)电阻,可直接用于「仪器仪表校准、医疗设备信号采集」等对阻值一致性要求苛刻的场景;

温度系数±25ppm/℃则保证了宽温下的阻值稳定性:以工作温度范围-55℃~+155℃为例,温差达210℃,阻值最大变化量为25×210×120×10⁻⁶=0.63Ω,相对变化仅0.525%,远低于±0.1%精度要求,可长期稳定工作在极端温度环境。

四、工作环境适应性

  • 温度范围:-55℃+155℃,超越普通工业级(-40℃+85℃),适配汽车电子(发动机舱高温)、户外工业传感器(低温严寒)等场景;
  • 薄膜电阻特性:抗老化、抗潮湿性能优于碳膜电阻,可降低长期使用中的阻值漂移,延长设备寿命;
  • 环保合规:符合RoHS标准(Viking光颉主流产品均满足),适配出口及绿色制造需求。

五、典型应用场景

  1. 精密仪器仪表:示波器、万用表的分压校准电路,确保测量精度;
  2. 工业控制模块:PLC模拟量输入的信号调理,稳定放大传感器信号;
  3. 汽车电子:胎压监测、发动机温度传感器的信号处理,适配-40℃~+125℃的汽车级环境;
  4. 通信设备:射频前端的匹配网络,小封装0603适配基站小型化需求;
  5. 医疗设备:监护仪的心率、血氧信号采集,高精度保障生命体征监测准确性。

六、品牌与可靠性保障

Viking光颉是全球知名的被动元器件制造商,薄膜电阻技术积累深厚,AR03BTC系列产品经严格可靠性测试(如高温老化、温度循环),批次一致性好,可满足批量生产的稳定需求;同时,该系列支持自动化贴片生产,适配SMT产线效率,降低生产制造成本。

该产品以「高精度、宽温稳定、小体积」为核心特点,是精密电子领域的高性价比选择。

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
