AR06FTD4993是光颉(Viking)推出的1206封装精密薄膜贴片电阻,针对中高精度电路设计,兼顾稳定性与环境适应性,广泛适用于工业控制、消费电子、汽车辅助系统等场景。
该电阻属于光颉薄膜电阻系列中的常规精密型号,以**±1%阻值精度**、低温度漂移为核心优势,解决普通电阻(如碳膜)在宽温、精密电路中阻值不稳定的问题;同时1206封装平衡了功率容量与PCB布局空间,适合中小信号电路的标准化设计,无需特殊定制即可满足多数常规精密场景需求。
标称阻值为499kΩ,精度等级±1%——实际阻值范围在494.01kΩ503.99kΩ之间,可满足电源反馈分压、传感器信号调理等对阻值误差敏感的电路(例如05V信号的精准分压,整体误差可控制在0.5%以内)。
采用1206封装(英制:0.12英寸×0.06英寸,公制:3.2mm×1.6mm),符合IPC标准:
光颉(Viking)作为专业电阻制造商,AR06FTD4993采用薄膜沉积+激光微调工艺,确保阻值精度与批量一致性;产品符合RoHS 2.0、无卤标准,环保合规;同时通过振动(10G)、冲击(50G)测试,满足工业级可靠性要求,可长期稳定运行于严苛场景。
该产品以高性价比、稳定性能成为中高精度电路的常规选择,适配多数标准化设计需求。

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.
