AR03BTCX9102是Viking(光颉)品牌推出的一款0603封装薄膜贴片电阻,针对对阻值精度、温度稳定性要求较高的应用场景设计,兼具小体积与高可靠性,是精密电子电路中的核心被动元件之一。其核心定位为“精密级小功率薄膜电阻”,可满足工业、通信、医疗等领域对阻值一致性与宽温稳定性的需求。
标称阻值为91kΩ(编码“9102”对应阻值计算:前两位“91”为有效数字,后两位“02”为10的幂次,即91×10²=91000Ω),精度等级为**±0.1%**——远高于常规厚膜电阻的±0.5%/±1%精度,可有效降低电路中的系统误差,避免因阻值偏差导致的信号失真或测量误差。
额定功率为100mW(0.1W),匹配0603封装的功率容量,可稳定承载中小信号电路的功率负载(如传感器信号调理、射频匹配网络等),避免过流导致的电阻老化或损坏。
温度系数为**±25ppm/℃**,代表每变化1℃,阻值相对变化百万分之25。以工作温区为例,若环境温度从25℃升至125℃(变化100℃),阻值变化量仅为91kΩ×25e-6×100=22.75Ω,相对误差约0.025%,远低于常规电阻的温漂表现,确保宽温环境下阻值稳定性。
支持**-55℃+155℃**宽温范围,覆盖工业级(通常-4085℃)及部分高温场景(如车载电子高温模块),适应极端环境下的长期稳定工作,无需额外散热或温度补偿设计。
公制尺寸为1.6mm×0.8mm(英制“0603”对应长0.06英寸、宽0.03英寸),体积小巧,可显著节省PCB布局空间,适合便携电子、高密度模块(如通信基站子卡、智能穿戴设备)的小型化设计,提升产品集成度。
采用镍铬合金薄膜沉积技术制备电阻层,相比厚膜电阻(印刷工艺),具有以下优势:
端电极采用多层结构(镍阻挡层+锡镀层),增强焊接兼容性与耐老化性能;电阻层与氧化铝基板结合紧密,可抵御机械应力、环境湿度等因素影响,符合IEC 61040、JIS C 5201等国际标准的可靠性要求,平均无故障时间(MTBF)达10^6小时以上。
AR03BTCX9102的高精度、高稳定性与小体积特性,使其广泛应用于以下领域:
Viking(光颉)作为台湾知名被动元件制造商,拥有30余年电阻研发与生产经验,产品通过ISO 9001质量管理体系认证,部分系列符合ISO/TS 16949汽车级标准,且满足RoHS、REACH等环保法规要求。AR03BTCX9102延续了品牌的高可靠性基因,可提供稳定的批量供货与技术支持,是客户实现产品性能优化的可靠选择。
综上,AR03BTCX9102凭借高精度、宽温稳定、小体积等核心优势,成为精密电子电路中替代常规电阻的理想方案,可有效提升产品性能与可靠性。
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.
