RK73H2ATTD10R0F是KOA推出的0805封装厚膜贴片电阻,主打「中小功率+高精度+宽温适应性」,兼顾成本与性能稳定性,广泛适配消费电子、工业控制、通信设备等领域的电路设计。
典型应用场景包括:
该电阻的核心参数直接决定适用场景,各参数的实际意义需结合电路需求理解:
±1%精度属于常规高精度范畴,远优于碳膜贴片(通常±5%),能满足对阻值一致性要求较高的电路。例如电流采样电路中,精准阻值可减少「I=V/R」的计算误差,提升监测精度。
0805封装的主流功率规格,适配大部分中小功率电路。需注意:实际功率需同时满足 P≤V²/R,即两端电压需≤√(250mW×10Ω)≈1.58V,避免电压过高导致功率超标。
此处150V为最大耐电压(非额定功率下的工作电压),表示电阻两端可承受的最高直流/交流电压(无击穿风险),但实际使用仍需以功率不超标为前提。
温度每变化1℃,阻值变化±100×10⁻⁶,即10Ω电阻每变化1℃,阻值变化±0.001Ω。例如环境温度从25℃升至125℃(变化100℃),阻值仅变化±0.1Ω,满足高温/低温波动场景的稳定性。
覆盖工业级宽温区,比常规商业级(0℃~70℃)更宽,可适配高温环境(如电源模块内部)或低温环境(如北方户外设备)。
英制0805封装(公制2012,尺寸2.0mm×1.2mm),体积小、重量轻,适合PCB布局紧凑的产品(如智能手机、可穿戴设备),有效提升电路集成度。
采用KOA成熟的厚膜电阻工艺(丝网印刷+高温烧结),相比薄膜电阻成本更低,相比碳膜电阻精度更高、稳定性更好。核心优势:
该产品通过多项行业可靠性测试,满足工业级应用要求:
RK73H2ATTD10R0F凭借「1%高精度、250mW功率、-55℃~155℃宽温」等核心优势,结合0805封装的紧凑性与厚膜工艺的成本优势,成为消费电子、工业控制等领域中小功率电路的高性价比选择,适配多种严苛应用场景。

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.
