Viking光颉AR03BTCX1043是一款工业级高精度薄膜贴片电阻,专为对阻值稳定性、误差控制及宽温适应性要求严格的电子电路设计。产品采用0603(英制)/1608(公制)小型贴片封装,标称阻值104kΩ,精度达±0.1%,温度系数(TCR)±25ppm/℃,额定功率100mW,工作温区覆盖-55℃至+155℃。其核心优势在于高稳定性、低温漂与小体积,可满足高密度PCB布局及极端环境下的性能需求。
TCR为±25ppm/℃,表示每变化1℃,阻值相对变化±25×10⁻⁶。以工作温区最大温差(210℃)计算,阻值最大变化量约546Ω,相对变化仅0.525%,远低于普通电阻温漂水平,保证宽温区下电路性能稳定。
采用镍铬薄膜工艺,相比碳膜、金属膜电阻具有:
AR03BTCX1043因高性价比与宽温适应性,广泛应用于:
薄膜层附着力强,长期使用阻值漂移量小,适合医疗仪器、航空航天辅助设备等对可靠性要求高的场景。
符合RoHS 2.0、REACH标准,无铅焊接,适配绿色电子产品设计。
4位标识“1043”对应104kΩ,需注意与3位标识“104”(100kΩ)的区别,避免选型错误。
若需更高精度(±0.05%)或更低TCR(±15ppm/℃),可参考光颉同系列升级型号;若功率需求更大,需选择0805及以上封装。
综上,AR03BTCX1043是一款兼顾精度、稳定性与成本的工业级贴片电阻,可满足多领域电子设备的核心性能需求。

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.
