Viking光颉ARG02DTC0220是一款0402封装精密薄膜贴片电阻,针对低功耗、高密度集成场景设计,核心参数聚焦“精准阻值+稳定性能+小体积”三大需求:
精密阻值,适配信号级电路
±0.5%的精度保证了分压、限流、信号衰减等场景的精准度——例如传感器信号调理电路中,22Ω电阻作为参考电阻,配合运放实现精准信号放大,避免阻值偏差导致的信号失真。
低温度漂移,宽温环境可靠
±25ppm/℃的TC意味着:环境温度从25℃升至125℃(温差100℃),阻值仅漂移约0.055Ω,远低于多数电路允许偏差,适合汽车电子(车身控制模块)、工业PLC等宽温应用。
0402小封装,助力设备小型化
封装尺寸仅1.0mm×0.5mm(长×宽),比0603封装体积缩小60%,可显著提升电路板集成密度——如智能手机主板电源管理模块中,多颗ARG02DTC0220节省空间,适配设备轻薄化趋势。
薄膜工艺,低噪声与长期稳定
采用真空溅射镍铬(NiCr)薄膜技术(而非厚膜印刷),电阻层均匀性更好,噪声系数低(适合音频、射频辅助电路),且长期使用阻值漂移极小(符合IEC 61000可靠性标准)。

Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
