ARG02FTC1503是光颉(Viking)电子推出的0402封装薄膜贴片电阻,专为高密度、高精度电路设计,兼顾小型化与稳定性能,可满足消费电子、工业控制等多领域的低功耗信号处理需求。
该电阻属于光颉ARG系列薄膜电阻的主力型号,核心定位为小型化高精度信号电阻——针对空间受限、精度要求高的电路场景(如可穿戴设备、智能手机射频前端),解决常规电阻“精度不足”或“封装过大”的痛点。其核心参数明确:阻值150kΩ、精度±1%、功率62.5mW,是薄膜电阻技术与0402封装的典型结合。
ARG02FTC1503标称阻值为150kΩ,精度等级达**±1%**——远高于常规碳膜电阻(±5%~±10%),可直接用于信号调理、分压电路等对阻值匹配要求较高的场景,无需额外校准。例如,在音频电路的音量控制中,±1%精度可保证声道间的阻抗一致性,避免信号失真。
额定功率为62.5mW,最大工作电压50V,符合低功耗电路的功率需求(如可穿戴设备的传感器供电电路)。实际使用中需注意:若电路瞬时功率超过额定值,可能导致金属膜氧化,长期使用阻值漂移会超过精度阈值。
温度系数(TCR)为**±25ppm/℃**,是薄膜电阻的核心优势之一。以常见工作温度变化(25℃→125℃,温差100℃)为例,阻值变化量为:
150kΩ × 25ppm/℃ × 100℃ = 375Ω
相对±1%的精度(1500Ω),仅占0.25%,远低于精度阈值,可保证宽温环境下的性能稳定。
采用0402封装(英制尺寸:0.04英寸×0.02英寸;公制尺寸:1.0mm×0.5mm),是贴片电阻中尺寸较小的规格之一,适配高密度PCB设计:
ARG02FTC1503的环境适应性覆盖多场景需求:
结合参数与封装特点,ARG02FTC1503的核心应用场景包括:
光颉(Viking)是全球知名的被动元器件制造商,ARG系列薄膜电阻采用高精度溅射薄膜工艺,批量生产一致性达±0.5%(优于标称±1%),可满足量产需求。此外,产品通过JIS C 5201(电子电阻器标准)测试,抗振动(10~2000Hz,1g加速度)、耐冲击(1000m/s²)性能符合工业级要求。
该型号凭借“小封装+高精度+宽温稳定”的综合优势,成为小型化高精度电路的常用选择,适用于对成本、性能、可靠性均有要求的终端产品。
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.
