AR03BTCX6802 薄膜贴片电阻产品概述

一、产品基本属性

AR03BTCX6802为Viking(光颉)品牌旗下的高精度薄膜贴片电阻,核心基础属性明确:

  • 封装规格:0603(英制代码,对应公制1.6mm×0.8mm);
  • 电阻类型:薄膜电阻;
  • 核心参数:标称阻值68kΩ、精度±0.1%、额定功率100mW、最大工作电压75V、温度系数±25ppm/℃;
  • 工作环境:-55℃~+155℃工业级宽温范围。

二、核心电气性能参数

(一)阻值与精度

该电阻标称阻值为68kΩ,精度控制在**±0.1%** 范围内,属于高精度电阻范畴。常温(25℃)下,实际阻值与标称值的偏差不超过±68Ω(68kΩ×0.1%),可满足对阻值一致性要求较高的电路设计(如信号调理、基准电压电路)。

(二)功率与电压额定值

  • 额定功率:100mW(环境温度≤70℃时,长期稳定工作的最大功率);
  • 最大工作电压:75V(直流/交流有效值,电阻两端可施加的最高电压)。
    需注意两者匹配:根据公式(P=U^2/R),75V电压下该电阻功耗约83.1mW,低于100mW额定值,满足安全工作要求。

(三)温度系数(TCR)

温度系数为**±25ppm/℃**,表示温度每变化1℃,阻值变化量为±25×10⁻⁶×标称阻值。以68kΩ为例,温度每升高/降低1℃,阻值变化约±1.7Ω,阻值稳定性较好,可适应温度波动较大的环境(如户外基站、工业车间)。

(四)工作温度范围

覆盖**-55℃+155℃**,超出商用级(0℃70℃)范围,属于工业级宽温规格,可在极端低温(如寒冷地区户外设备)或高温(如机房密集散热环境)下稳定工作。

三、封装与物理特性

采用0603贴片封装,是小型化表面贴装电阻的典型规格,适配现代SMT(表面贴装技术)生产线,可实现高速自动化贴装。其体积紧凑(约1.6mm×0.8mm×0.45mm,参考行业标准),适合高密度PCB设计,尤其适用于对空间要求严格的小型化电子设备(如智能穿戴、便携医疗设备)。

四、典型应用场景

基于高精度、宽温稳定、小体积的特点,AR03BTCX6802广泛应用于:

  1. 工业控制:PLC信号调理、温度/压力变送器、工业仪表(需高精度阻值保证信号准确);
  2. 通信设备:基站射频模块、路由器/交换机信号处理单元(宽温适配户外/机房环境);
  3. 医疗电子:监护仪、心电图机的信号放大电路(高精度确保生理信号检测准确);
  4. 高端消费电子:Hi-Fi音频放大器、智能手表传感器电路(小体积满足便携性)。

五、品牌与可靠性

Viking(光颉)在薄膜电阻领域拥有成熟工艺,AR03BTCX6802采用薄膜电阻技术(相比碳膜/金属膜,噪声更低、稳定性更高),长期使用阻值漂移小,符合工业级可靠性标准,可满足对电阻性能要求严苛的场景。

该产品平衡了高精度、宽温稳定性与小体积,是工业、通信、医疗等领域高精度电路设计的适配选择。

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
