ARG05FTC3000是光颉(Viking)ARG系列中的0805封装高精度薄膜贴片电阻,专为小型化、高稳定性电路设计。其核心基础参数清晰明确:阻值300Ω、精度±1%、额定功率125mW、工作电压150V、温度系数±25ppm/℃,工作温度范围覆盖-55℃~+155℃,适配工业级及部分汽车级应用的基础需求。
该型号采用薄膜电阻工艺(真空溅射/沉积电阻膜),阻值精度达±1%——远高于普通碳膜/厚膜电阻的±5%~±10%,可满足信号调理、分压网络等对阻值一致性要求较高的场景。薄膜结构的长期漂移率(通常<0.1%/1000小时)低于厚膜电阻,进一步保障电路性能的持久稳定。
额定功率125mW是0805封装的常规小功率等级,适配低功耗电路设计;150V持续工作电压(非瞬时击穿电压)表明其绝缘层与封装材料可承受较高电压应力,避免漏电流或击穿问题,适用于中低压模拟电路。
温度系数(TC)±25ppm/℃属于薄膜电阻的中高精度水平:以300Ω为例,温度变化100℃时,阻值仅变化0.75Ω(远小于±1%精度对应的3Ω偏差),可有效降低温度波动对电路的影响。-55℃~+155℃的宽温范围,覆盖户外工业设备、车载环境等极端温度场景,无需额外温控即可稳定工作。
薄膜电阻的环氧树脂封装密封性好,抗湿、抗腐蚀能力优于厚膜;可通过回流焊、波峰焊等SMT工艺,焊接后阻值无明显变化;符合RoHS、REACH环保标准,无铅无卤,适配绿色制造需求。
ARG05FTC3000采用0805英制封装(公制2012,尺寸2.0mm×1.2mm×0.5mm),是贴片电阻主流小型化封装之一,适配自动化SMT生产线,可实现高速贴装,降低生产升本。引脚采用镍钯金(Ni/Pd/Au)镀层,焊接兼容性好,避免虚焊、冷焊缺陷,提升成品率。
结合性能参数,该型号可广泛应用于:
光颉(Viking)作为全球被动元件制造商,ARG系列电阻经过严格质量管控:每批次均做精度测试、温漂测试、功率老化测试;可提供符合IEC 61000-4-2(ESD防护)、AEC-Q200(汽车级)的定制版本,拓展应用场景。
ARG05FTC3000凭借薄膜电阻的高精度、宽温稳定性与小尺寸封装,成为小型化高要求电路的优选被动元件。

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.
