AR05BTCW1003 薄膜贴片电阻产品概述

一、产品基本属性

AR05BTCW1003是Viking(光颉)品牌推出的0805封装精密薄膜贴片电阻,属于该品牌薄膜电阻系列的核心型号。产品采用真空溅射薄膜工艺制造,区别于厚膜电阻的网印工艺,具备更高精度、更低温度系数及长期稳定性,是对阻值一致性要求严苛场景的首选元件。型号中“1003”为阻值编码,对应标称阻值100kΩ(100×10³Ω),明确了核心阻值规格。

二、核心性能参数详解

1. 阻值与精度

标称阻值为100kΩ,精度等级达**±0.1%**,属于精密级电阻范畴。薄膜工艺通过均匀沉积电阻膜并精准刻蚀,使阻值偏差控制在极小范围,相比厚膜电阻(典型精度±1%~±0.5%)更适合仪器校准、精密信号调理等对偏差敏感的应用。

2. 功率与电压额定值

  • 额定功率125mW:25℃环境下可长期稳定工作的最大功率,需注意实际工作时需满足功率限制(公式:(P=V^2/R));
  • 工作电压150V:绝对最大额定值,连续工作电压需控制在约112V以内(避免150V下瞬时功率225mW超过额定值)。

3. 温度系数(TCR)

温度系数为**±25ppm/℃**,表示阻值随温度变化的速率。以100kΩ为例,每升高1℃阻值变化约2.5Ω;温度变化100℃时,阻值变化仅250Ω,仍远低于±0.1%(100Ω)的精度范围,确保宽温环境下性能稳定。

4. 工作温度范围

覆盖**-55℃~+155℃**,符合工业级宽温要求,可适应汽车发动机舱、户外工业设备等极端环境,在高低温循环中无明显性能漂移。

三、封装与物理特性

采用0805封装(英制:0.08″×0.05″,公制:2.0mm×1.2mm),属于小型贴片封装,适合高密度PCB布局,可通过自动化贴装设备实现高效生产。产品符合RoHS环保标准,无铅无卤,满足全球电子行业环保法规要求。

四、品牌与可靠性保障

Viking(光颉)是全球知名被动元件制造商,专注电阻研发30余年,薄膜电阻工艺成熟。AR05BTCW1003经过严格可靠性测试:

  • 高温存储(155℃/1000h)后阻值变化率≤0.1%;
  • 温度循环(-55℃~+155℃/1000次)后TCR漂移≤5ppm/℃;
  • 湿度测试(85℃/85%RH/1000h)后性能无明显衰减。
    产品符合IEC、JIS等国际标准,长期可靠性有保障。

五、典型应用领域

基于高精度、宽温、小封装特点,该电阻广泛应用于:

  1. 精密测量仪器:万用表、示波器、频谱分析仪的校准电路、信号放大模块;
  2. 工业控制:PLC模拟量输入、传感器信号调理(压力/温度传感器);
  3. 通信设备:射频前端滤波、基站电源监控;
  4. 汽车电子:车身控制单元(BCM)、胎压监测(TPMS)、发动机传感器;
  5. 高端消费电子:Hi-Fi音频解码、电源电压监控电路。

该产品平衡了精度、稳定性与成本,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
