ARG02BTC5362是Viking(光颉)电子推出的高精度薄膜贴片电阻,属于其针对精密电子领域的核心产品线。Viking作为全球知名被动元件制造商,专注电阻研发超20年,薄膜电阻系列以“高精度、低温漂、高稳定性”为核心竞争力,覆盖工业、汽车、通信等严苛场景。ARG02BTC5362针对小尺寸、高精密电路设计,填补了0402封装下±0.1%精度、宽温区(-55℃~+155℃)电阻的市场需求,是终端产品小型化与性能升级的优选器件。
ARG02BTC5362的参数围绕“精密、稳定”两大核心,关键性能及价值如下:
标称阻值53.6kΩ,精度±0.1%——远高于普通厚膜电阻的±1%~±5%,批量生产一致性达千分之一级,可减少终端产品校准工序,降低生产成本(尤其适合医疗、仪器类需精准度的场景)。
额定功率62.5mW,最大工作电压50V——匹配0402封装的功率容量,满足小信号电路(如传感器放大、射频偏置)的功耗需求;电压上限避免器件击穿风险,保障电路长期安全运行。
±25ppm/℃——温度变化对阻值影响极小:以-55℃~+155℃宽温范围计算,阻值最大变化量仅约26.8Ω(占标称值0.05%),确保电路在极端温度下性能稳定(如汽车发动机舱、高寒工业环境)。
-55℃~+155℃——覆盖工业级、汽车级温度要求,可适应高温老化、低温启动等恶劣工况,无需额外降额设计。
采用0402(英制)/1005(公制)封装,尺寸仅1.0mm×0.5mm、厚度约0.3mm——适合高密度PCB设计,满足智能手机、智能穿戴、小型工业模块等对空间严苛的应用。
采用镍铬(NiCr)薄膜技术:通过真空溅射形成均匀薄膜层,再经激光微调实现高精度阻值;薄膜层均匀性远优于厚膜电阻,老化效应(长期阻值漂移)仅为厚膜的1/5~1/10,长期稳定性更突出。
陶瓷基底+环氧树脂封装,密封性符合IEC 60068-2-67湿热循环标准,可抵抗潮气、灰尘侵蚀,提升环境适应性。
ARG02BTC5362通过多项行业标准测试,满足工业级、汽车级要求:
ARG02BTC5362因“小尺寸、高精度、宽温稳”特性,广泛应用于:
综上,ARG02BTC5362是一款兼具“小尺寸、高精度、宽温稳定”的薄膜贴片电阻,可有效支撑终端产品的小型化、高性能升级,适配多行业严苛应用需求。
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.
