RK73H1ETTP1501F是日本KOA株式会社推出的0402封装厚膜贴片电阻,属于KOA经典RK73系列的中端通用型产品。KOA作为全球知名电子元件制造商,拥有超过70年的电阻研发与生产经验,产品以高可靠性、宽温适应性著称,广泛覆盖工业、汽车、消费电子等领域。该电阻针对中小信号电路的精度需求设计,兼顾性能与成本,适合高密度PCB布局场景。
该电阻的核心参数完全匹配通用电路的典型需求,关键指标如下:
该电阻采用0402英制封装(对应公制1005,尺寸1.0mm×0.5mm),是贴片电阻中体积较小的封装之一,适合高密度PCB设计(如可穿戴设备、智能手机)。结构上采用厚膜工艺:在氧化铝陶瓷基底上印刷钌基电阻浆料,经高温烧结形成电阻层,再通过镍-锡镀层端电极实现表面贴装连接。厚膜工艺平衡了成本与性能,比薄膜电阻成本更低,比碳膜电阻精度更高。
该电阻因体积小、精度高、宽温适应,广泛应用于以下领域:
KOA对该电阻进行了严格的可靠性验证,符合以下标准:
该电阻凭借平衡的性能与成本优势,成为中小信号电路的高性价比选择,适合批量应用于对精度、宽温有要求的电子设备中。

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.
