RMS06FT8251是大毅科技推出的通用型厚膜贴片电阻,采用0603(英制)/1608(公制)小封装设计,针对精度要求±1%、功率需求100mW的中小功率电路场景优化,兼顾成本与可靠性,是消费电子、工业控制、汽车电子等领域的常用选型。
核心特征可总结为:
标称阻值8.25kΩ(标识代码“8251”对应E96系列:825×10¹=8.25kΩ),精度±1%,在25℃标准温度下,阻值偏差控制在8167.5Ω~8332.5Ω之间,满足信号调理、分压电路等对参数一致性的要求。
温度系数±100ppm/℃,即温度每变化1℃,阻值变化量为8.25kΩ×100×10⁻⁶=0.825Ω。该温漂范围适合温度变化幅度较小的场景,若需更高温稳性,可结合电路补偿设计。
-55℃~+155℃的宽温范围符合AEC-Q200(汽车电子)与工业级标准,可在车载、户外设备等极端温度环境下长期可靠工作。
封装尺寸为1.6mm×0.8mm(公制1608),体积小、重量轻,适合高密度PCB布局(如智能手机、智能穿戴主板),可有效提升电路集成度。
大毅科技采用陶瓷基片+电阻浆料印刷、烧结工艺,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,阻值一致性可控制在±1%以内,批量生产良率高。
引脚采用镍/金镀层,兼容回流焊、波峰焊等常规贴片焊接工艺,焊接后焊点可靠性高,抗振动冲击能力符合IEC 60068-2-6(振动测试)标准。
RMS06FT8251的参数特性使其广泛应用于以下领域:
大毅科技的品质管控覆盖从浆料制备到成品测试的全流程,产品经过高温老化、湿度循环、振动冲击等测试,MTBF(平均无故障时间)可达10⁶小时以上。
作为成熟型号,RMS06FT8251具备稳定量产能力,可满足中小批量到大规模订单的交付需求,交期可控。
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.
