Viking光颉AR03BTCX1200为薄膜贴片电阻,核心参数精准匹配精密电路需求,关键指标如下:
0603封装是贴片电阻的主流小尺寸规格,适配高密度PCB设计(如智能手机、小型通信模块),可显著提升电路集成度;100mW额定功率虽为小功率,但针对其120Ω阻值,实际应用中可覆盖「小信号调理、精密分压」等场景(如传感器输出信号的放大前分压),无需担心功率过载。
需注意:实际使用时需根据电路实际电压/电流计算功率,确保不超过100mW阈值。
该电阻的**±0.1%精度**是核心优势之一,远高于普通碳膜(±5%)、金属膜(±1%)电阻,可直接用于「仪器仪表校准、医疗设备信号采集」等对阻值一致性要求苛刻的场景;
温度系数±25ppm/℃则保证了宽温下的阻值稳定性:以工作温度范围-55℃~+155℃为例,温差达210℃,阻值最大变化量为25×210×120×10⁻⁶=0.63Ω,相对变化仅0.525%,远低于±0.1%精度要求,可长期稳定工作在极端温度环境。
Viking光颉是全球知名的被动元器件制造商,薄膜电阻技术积累深厚,AR03BTC系列产品经严格可靠性测试(如高温老化、温度循环),批次一致性好,可满足批量生产的稳定需求;同时,该系列支持自动化贴片生产,适配SMT产线效率,降低生产制造成本。
该产品以「高精度、宽温稳定、小体积」为核心特点,是精密电子领域的高性价比选择。

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.
