ARG05FTC1802是光颉(Viking)针对精密电子电路推出的0805封装薄膜贴片电阻,核心聚焦「高稳定性、宽温适应性、小体积集成」三大优势。该产品采用真空溅射薄膜工艺制造,阻值18kΩ±1%,额定功率125mW,可在-55℃~+155℃宽温范围内稳定工作,温度系数低至±25ppm/℃,是工业控制、汽车电子等对精度与可靠性要求较高场景的优选元件。
固定阻值18kΩ,精度±1%,满足精密信号调理、反馈电路的阻值一致性需求——相比±5%精度的普通电阻,可减少电路性能波动(如电源电压调节偏差、传感器信号失真等)。
温度系数(TCR)±25ppm/℃,意味着在-55℃~+155℃范围内,每变化1℃阻值漂移仅0.45Ω(18kΩ×25ppm),远优于普通碳膜电阻(±500ppm/℃以上),宽温环境下性能稳定。
-55℃+155℃,覆盖工业级(-40℃+85℃)与汽车级(-40℃~+125℃)的温度需求,无需额外降额即可应对极端温变场景。
0805封装(英制0.08×0.05英寸,公制≈2.0×1.25mm),体积小巧,适配高密度PCB设计,符合消费电子、通信设备的小型化趋势。
相比厚膜电阻,薄膜工艺通过真空溅射制备电阻层,具有:
支持回流焊、波峰焊等常规贴片工艺,焊接温度曲线符合行业标准(回流焊峰值温度≤260℃,时间≤10秒),便于批量生产。
ARG05FTC1802的性能特性使其广泛适用于:
光颉通过多项可靠性测试确保产品稳定:
该产品平衡了精度、稳定性与体积,是精密电子设计中替代普通电阻的高性价比选择。

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.
