ARG03BTC2432是Viking(光颉)推出的高精度小型化薄膜贴片电阻,针对对阻值精度、温度稳定性要求严苛的电子电路设计。其核心属性明确:采用0603封装(英制尺寸1.6mm×0.8mm),额定功率100mW,标称阻值24.3kΩ,是兼顾「小型化」与「高可靠性」的专业电阻元件,适配工业、通信、医疗等领域的高密度PCB布局需求。
该电阻的性能参数围绕「高精度、宽温稳、小体积」三大方向设计,具体优势如下:
标称阻值24.3kΩ,精度达**±0.1%**——远高于普通碳膜电阻(通常±1%~±5%),可有效降低分压、电流检测等电路的误差。例如在万用表分压电路中,能确保测量值与真实值的偏差控制在极小范围,满足精密仪器对阻值一致性的要求。
温度系数(TCR)为**±25ppm/℃**,意味着温度每变化1℃,阻值仅变化百万分之25。以工作温度范围(-55℃~+155℃)计算,最大阻值变化量为210℃×25ppm=0.00525(即5.25‰),远低于精度要求,可保证宽温环境下阻值始终稳定,无需额外温度补偿设计。
100mW额定功率适配小功率电路长期运行,75V最大工作电压提供充足安全裕量——避免过压损坏的同时,满足多数低压电路(如3.3V、5V系统)的电压需求,兼顾可靠性与实用性。
覆盖**-55℃至+155℃**,符合工业级温度标准,可适应户外基站、工厂车间等极端环境(高低温、湿度变化),无需额外散热或防护设计。
采用国际通用的0603贴片封装,体积紧凑(1.6mm×0.8mm),适合高密度PCB布局——可有效缩小终端产品尺寸(如可穿戴设备、小型测试仪器),适配当下电子设备「轻薄化」趋势。
基于镍铬合金薄膜制造工艺,相比厚膜电阻具有三大优势:
贴片封装焊接牢固,抗振动、抗冲击能力优于插件电阻,可适应汽车、工业设备等振动环境;同时符合RoHS、REACH等环保标准,无铅无卤,满足绿色制造要求。
Viking(光颉)是全球知名的电阻制造商,在薄膜电阻领域拥有20余年研发与制造经验。ARG03BTC2432采用其成熟的自动化生产流程:从薄膜沉积、光刻图案到阻值微调,全程高精度控制;每批次产品均经过100%精度测试、温度循环测试及老化测试,确保参数一致性与长期可靠性。
该电阻因性能特点,广泛适配以下领域:
综上,ARG03BTC2432是一款「高精度、宽温稳、小体积」的薄膜贴片电阻,可满足多领域对电阻性能的严苛要求,是电子电路设计中可靠的基础元件。
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.
