RK73H1ETTP9091F是日本KOA公司推出的0402封装厚膜表面贴装电阻,专为高密度、高可靠性电子电路设计,核心聚焦「小型化+精密阻值+宽温适应性」三大优势,适配消费电子、汽车电子、工业控制等多领域需求。
其核心特性可总结为:
标称阻值9.09kΩ±1%,属于厚膜电阻中的「精密级」。该阻值并非随机设计——9.09kΩ是10kΩ的0.909倍(近似1/11),常被用于分压电路、运放偏置、ADC参考电压调理(例如将5V输入分压为0.4545V,适配12位ADC小信号输入),精度±1%可避免阻值偏差导致的测量误差。
采用0402表面贴装封装(英制:0.04″×0.02″;公制:1.0mm×0.5mm),具备三大优势:
结合参数特性,RK73H1ETTP9091F的典型应用集中在:
作为KOA核心产品,具备以下可靠性优势:
RK73H1ETTP9091F是高性价比精密厚膜电阻,以0402小型封装、±1%精度、宽温适应性为核心,覆盖多领域需求。明确的额定参数、稳定的温度特性,可降低电路设计风险,是紧凑电路中替代碳膜电阻的理想选择。

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.
