RTT011273FTH是台湾旺诠(RALEC)推出的一款小体积精密厚膜贴片电阻,采用0201行业标准封装,针对低功耗、高密度电路场景优化设计,兼顾精度稳定性与宽温适应性,可满足消费电子、工业控制、汽车电子等多领域的基础信号调理与功率分配需求。
该型号电阻的核心参数围绕“低功耗+高稳定性”设计,关键指标明确且适配多场景:
实际使用需遵循功率降额原则:当环境温度超过70℃时,额定功率需按线性比例降低,确保长期可靠性。
旺诠依托20余年厚膜电阻制造经验,在RTT011273FTH的工艺与材料上实现了性能优化:
采用高精度丝网印刷技术,将定制化银钯合金电阻浆料印刷在氧化铝陶瓷基板上,经1000℃以上高温烧结形成致密电阻膜层。该工艺避免了薄膜电阻的成本劣势,同时比碳膜电阻的阻值一致性更高(控制在±0.5%以内,远优于标称±1%)。
RTT011273FTH的参数特性使其适配多类低功耗、高密度电路:
如智能手机、智能手环、蓝牙耳机等设备的信号调理电路(例:传感器输出分压、射频信号匹配、音频信号衰减),0201小体积可显著缩小PCB尺寸,50mW功率适配电池供电的低功耗需求。
用于PLC模块、传感器接口的分压/限流网络,-55℃~+125℃宽温范围可适应车间高温、低温环境,±1%精度满足工业级信号采集的准确性要求。
如车载中控的按键电路、胎压监测模块的信号滤波、车灯控制的限流电路,汽车级温度范围(-40℃~+85℃)完全覆盖,厚膜电阻的抗震动性能(符合AEC-Q200标准)可应对车辆行驶中的机械冲击。
如便携式血糖仪、心率监测仪的电源反馈电路,25V最大电压满足安全规范,低功耗设计延长设备续航时间。
旺诠对该型号电阻进行了多项可靠性测试,验证其长期稳定性:
旺诠是全球知名的被动元件制造商,产品通过ISO 9001、ISO 14001、AEC-Q200等国际认证,RTT011273FTH的批次一致性优于行业平均水平,可降低客户批量生产的选型风险。
0201封装体积仅为0.6mm×0.3mm,比0402封装缩小约70%,可大幅提升PCB的集成密度,适合高密度电路设计(如智能手机主板、智能穿戴设备)。同时,该封装兼容自动化贴装设备,生产效率高,适合大规模量产。
RTT011273FTH作为旺诠推出的高性价比厚膜贴片电阻,以“小体积、低功耗、宽温稳定、高可靠性”为核心优势,覆盖消费电子、工业控制、汽车电子等多领域应用。其参数设计贴合现代电路的“小型化、低功耗”趋势,同时通过严格的可靠性测试,可满足客户对长期稳定运行的需求,是精密低功耗电路的理想选型之一。
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.
