ARG05BTC3000是Viking(光颉)针对精密电子电路推出的高性能薄膜贴片电阻,核心聚焦“高精度、宽温稳定、小封装适配”三大优势,可替代传统低精度电阻满足工业级、医疗级等场景的严苛需求。其核心亮点包括:
ARG05BTC3000的电气参数经过严格校准,核心指标可支撑多数精密场景应用:
标称阻值300Ω,精度±0.1%,实际阻值范围为299.7Ω~300.3Ω,可满足示波器、数字万用表等设备的校准级阻值要求,批量一致性优于普通金属膜电阻。
±25ppm/℃表示每升高1℃,阻值变化±25×10⁻⁶Ω。例如:当工作温度从25℃升至125℃(变化100℃),阻值变化仅**±0.25%**,远优于普通碳膜电阻(典型±100ppm/℃以上)。
薄膜电阻采用真空沉积工艺,电流噪声典型值<0.1μV/V,适合低噪声信号处理电路(如音频放大器、传感器前端)。
采用0805英制贴片封装,尺寸为2.0mm(长)×1.2mm(宽)×0.5mm(厚),适配常规SMT贴装工艺,支持高密度PCB布局(如手机、路由器等小型化设备)。
工作温度范围-55℃+155℃,符合工业级I级温度标准,可稳定工作于汽车发动机舱(-40℃+125℃)、户外基站(-20℃~+55℃)等极端场景。
环氧树脂封装+薄膜电阻层设计,具备抗潮湿(湿度范围095%RH)、抗振动(102000Hz,加速度2g)性能,长期工作漂移率<0.05%/1000小时。
ARG05BTC3000因高精度、宽温稳定特性,广泛覆盖以下领域:
示波器、函数发生器、数字万用表等设备的信号校准电路,需准确阻值保证测量精度。
监护仪、血糖仪、输液泵的信号调理模块,对阻值一致性要求高,且需适配低温(如冷链设备)环境。
基站射频模块、路由器信号滤波电路,小封装适配高密度PCB,宽温满足户外基站的温度波动。
车身控制模块(BCM)、胎压传感器信号处理电路,适应汽车-40℃~+125℃的工作环境。
PLC模块、伺服驱动器的反馈电路,宽温范围满足工业现场(如车间、油田)的温度变化。
Viking(光颉)作为专业被动元件制造商,ARG系列电阻通过以下品质控制:
ARG05BTC3000凭借“高精度+宽温稳定+小封装”的综合优势,成为精密电子领域的高性价比选择,可有效提升电路性能的一致性与可靠性。
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.
