ARG03FTC2493 为 Viking(光颉) 系列高稳定性薄膜贴片电阻,阻值 249kΩ,精度 ±1%,额定功率 100mW。采用 0603(1608公制)封装,尺寸小、热容量低,适合高密度表贴电路板设计。薄膜工艺保证低噪声和良好阻值稳定性,适用于精密模拟与测量电路。
薄膜工艺带来低噪声和低漂移特性,TCR ±25ppm/℃ 确保温度变化下阻值稳定。高精度 ±1% 满足严格电阻配对需求。额定功率与 0603 尺寸的平衡使其在功耗受限但需小体积的应用中表现优秀。寿命与焊接可靠性符合工业级要求。
适用于电源分压、信号调理、电流采样、滤波与阻抗匹配等电路。特别适合便携设备、传感器前端、仪表放大器、消费电子与工业控制系统中对精度与稳定性有要求的场合。
工作温度范围宽(-55℃ 至 +155℃),可满足严苛环境工作需求。薄膜电阻抗湿性、热冲击和机械冲击性能良好,符合常见的军工/工业环境可靠性测试要求(详见具体检测报告)。
0603 表贴封装,适配自动贴片与回流焊流程。出厂采用卷盘包装(Reel)或托盘,便于 SMT 生产线高速贴装。包装与标识遵循行业标准,支持批次追溯。
推荐回流焊温度曲线与 PCB 焊盘设计遵循 0603 标准,避免过长高温暴露以保持阻值稳定。建议预留足够散热路径和焊盘尺寸以降低局部温升。存储环境避免潮湿与强腐蚀性气体,开封后短期内使用为佳。
标准型号 ARG03FTC2493,品牌 Viking(光颉)。订购时请注明阻值与容差,确认包装形式(卷盘/散装)和交货批次。如用于关键系统,请索取详细可靠性报告与 RoHS/REACH 合规文件以便验证。若需量产级或特殊等级测试,可联系供应商定制检测方案。

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.
