AR03BTCX7801N 贴片薄膜电阻产品概述

一、产品基本属性

Viking(光颉)推出的AR03BTCX7801N是一款0603封装贴片薄膜电阻,核心规格清晰明确:

  • 标称阻值:7.8kΩ
  • 精度等级:±0.1%
  • 额定功率:100mW
  • 温度系数(TCR):±25ppm/℃
  • 工作温度范围:-55℃ ~ +155℃

该产品基于薄膜电阻技术打造,兼顾高精度与环境稳定性,适配对参数一致性要求严格的电子设计场景。

二、技术性能核心特点

1. 高精度与低偏差控制

标称阻值7.8kΩ的精度达±0.1%,可直接满足多数精密电路对电阻偏差的严苛要求(如传感器信号调理、仪器校准电路),无需额外匹配电阻即可实现信号精度达标,减少设计冗余。

2. 低温度漂移特性

±25ppm/℃的TCR意味着阻值随温度变化的漂移极小:以工作温度范围(-55℃~+155℃,温差210℃)为例,阻值最大变化量仅约0.395Ω,远低于精度阈值,适合宽温环境下的长期稳定应用。

3. 小功率适配性

100mW额定功率匹配低功耗电路设计(如物联网终端、小型通信模块),常规使用无需额外降额,可稳定承载电路负载,同时降低整体功耗。

4. 薄膜电阻技术优势

相比厚膜电阻,薄膜电阻采用真空沉积工艺形成电阻层,具有更低噪声系数(典型值<1nV/√Hz)、更好线性度,适合模拟电路、射频前端等对信号质量敏感的场景。

三、封装与生产适配性

采用0603英寸标准贴片封装(公制尺寸:1.6mm×0.8mm×0.45mm,典型值),符合国际电子封装标准:

  • 兼容常规贴片生产工艺(回流焊、波峰焊),无需特殊设备;
  • 焊盘设计与通用0603封装一致,可直接集成于标准PCB布局,降低设计门槛;
  • 紧凑尺寸适配高密度电路(如便携式医疗设备、5G基站小模块),有效节省PCB空间。

四、典型应用场景

该产品因高精度、宽温稳定、小封装等特性,广泛适用于以下领域:

  1. 工业控制:PLC模块、传感器信号放大电路(宽温适配车间复杂环境);
  2. 医疗电子:监护仪、血糖仪的信号调理单元(低漂移保障医疗数据准确性);
  3. 通信模块:5G基站辅助电路、物联网终端射频匹配网络(小封装适配高密度设计);
  4. 精密仪器:万用表校准电路、音频设备信号处理单元(高精度满足专业需求)。

五、可靠性与环境适应性

  1. 宽温可靠性:-55℃~+155℃的工作范围覆盖工业、医疗、汽车(部分场景)的环境要求,无需额外温度补偿;
  2. 长期稳定性:经Viking光颉可靠性测试(1000小时负载寿命测试),阻值变化≤0.1%,满足长期使用需求;
  3. 耐环境性能:符合常规贴片电阻耐湿(85℃/85%RH,1000小时阻值变化≤0.2%)、耐振(10~2000Hz,2g加速度,阻值变化≤0.1%)标准,适配运输与现场使用。

总结

AR03BTCX7801N凭借高精度、宽温稳定、小封装及薄膜电阻的低噪声优势,成为7.8kΩ阻值场景下的优选贴片电阻,可有效支撑工业、医疗、通信等领域的精密电子设计需求。

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
