AR02DTD1001是Viking(光颉) 推出的一款精密贴片薄膜电阻,采用行业通用的0402封装(英制代码:0.04英寸×0.02英寸,公制尺寸约1.0mm×0.5mm),属于薄膜电阻类别。该产品针对小体积、高精密电路设计,兼顾宽温稳定性与可靠性,是消费电子、工业控制、汽车电子等领域的常用元件。
AR02DTD1001的关键参数均围绕“精密稳定”设计,具体如下:
标称阻值为1kΩ,精度等级为**±0.5%** —— 即实际阻值范围在995Ω~1005Ω之间,满足多数模拟电路对阻值一致性的要求(如信号放大、分压网络等场景)。
温度系数为**±50ppm/℃**,表示温度每变化1℃,阻值变化量为标称值的±50×10⁻⁶(1kΩ时每度变化±0.05Ω)。该系数使产品在宽温范围内阻值漂移极小,适合极端环境应用。
覆盖**-55℃~+155℃**,符合汽车电子AEC-Q200标准的温度要求,可稳定工作于工业高温、车载低温等场景。
0402封装是目前贴片电阻中体积最小的规格之一,具有以下特点:
AR02DTD1001的参数特性使其适用于以下场景:
智能手机、智能手表的音频电路(精密分压、信号滤波)、电源管理模块的反馈网络,以及便携设备的传感器信号调理。
PLC(可编程逻辑控制器)的模拟量输入电路、传感器(温度、压力)的信号放大环节,以及工业仪器的精密测量模块。
车载信息娱乐系统的音频处理电路、发动机ECU的传感器信号滤波,以及车身控制模块的小信号电路(宽温范围适配车载环境)。
4G/5G基站的射频前端匹配网络、光纤收发器的偏置电路,以及路由器的信号调理模块。
综上,AR02DTD1001是一款兼顾小体积、高精密与宽温稳定性的贴片薄膜电阻,适合对阻值精度、环境适应性有要求的中高端电子设备设计。

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.
