AR03BTCX2001是Viking(光颉) 推出的一款0603封装薄膜贴片电阻,以2kΩ标称阻值、±0.1%高精度为核心特性,适配对阻值稳定性、温度适应性要求较高的电子设计场景,兼顾小型化与工业级可靠性,是信号调理、基准电路等领域的实用选择。
阻值与精度
标称阻值为2kΩ(对应电阻代码“2001”),精度等级±0.1%——这一指标远高于普通碳膜电阻(通常±5%),能满足电路中对电阻偏差严格控制的需求(如信号分压、基准校准等),减少后期电路校准成本。
功率与封装适配
额定功率100mW,匹配0603封装(英制0.06×0.03英寸,公制1.6mm×0.8mm)。该封装下的功率表现符合薄膜电阻的承载特性,既支持小型化PCB布局,又能稳定应对低功耗电路的功率需求。
温度系数(TCR)
温度系数为±25ppm/℃,表示温度每变化1℃,阻值变化约±50mΩ(2kΩ×25×10⁻⁶)。低TCR特性确保了在宽温度范围内的阻值稳定性,避免因环境温度波动导致电路性能漂移(如传感器信号放大电路的精度衰减)。
工作温度范围
覆盖-55℃至+155℃,远超民用级电阻(通常0℃~70℃),可适应工业现场高低温、汽车发动机舱周边高温等极端环境,提升产品长期可靠性。
0603封装优势
体积紧凑(1.6mm×0.8mm),适合高密度PCB设计(如智能手机、智能穿戴的射频前端);表面贴装(SMD)工艺兼容自动化生产线,降低生产难度与人工成本。
薄膜电阻工艺
采用镍铬/钌基薄膜技术,相比碳膜、金属氧化膜电阻,具有以下优势:
高精度信号调理电路
如传感器(压力、温度)的信号放大、数据采集模块的滤波分压——±0.1%精度与低TCR确保信号失真度低,输出稳定。
基准电压与参考电路
电压基准源的分压网络、ADC/DAC的参考电阻——需阻值精确且随温度变化小,该产品可减少基准输出漂移。
小型化消费电子
智能手机、智能手表的电源管理(如电池充放电控制)、射频前端电路——0603封装适配紧凑设计,100mW功率满足低功耗需求。
工业控制与汽车电子
工业PLC的输入输出模块、汽车传感器信号处理电路——宽温范围(-55℃~+155℃)适应极端环境,可靠性符合工业级要求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
