RN73H1ETTP1002B25是KOA品牌0402封装高精度金属膜贴片电阻,针对小信号电路中对阻值精度、稳定性要求较高的场景设计,兼具小型化、高可靠性特点,可替代同类低精度电阻提升电路性能,适用于消费电子、工业控制、通信设备等多领域。
标称阻值10kΩ,精度±0.1%——属于“高精度电阻”范畴,可满足分压电路、反馈网络等对阻值一致性要求高的设计,避免因阻值偏差导致的电路输出误差(例如在12V电源分压为3.3V的电路中,0.1%精度可将输出误差控制在±3.3mV内)。
温度系数±25ppm/℃——衡量阻值随温度变化的核心指标:温度每变化1℃,阻值变化0.0025%。以工作温度范围(-55℃+155℃)计算,总阻值变化量约0.525%,远低于普通碳膜电阻(通常100500ppm/℃),可保证高低温环境下电路性能稳定(如工业车间高温场景或户外低温场景)。
-55℃~+155℃:覆盖工业级、部分汽车级温度需求,无需额外散热设计即可适应极端环境,提升产品适用场景广度。
采用0402封装(英制:0.04″×0.02″;公制:1.0mm×0.5mm),体积仅为常规1206封装的1/9,可大幅提升PCB贴装密度,适合智能手机、智能穿戴等小型化终端产品的布局需求。
通过真空溅射金属膜技术制备电阻体,相比碳膜电阻具有三大优势:
KOA作为日本老牌电子元器件制造商(成立于1940年),在电阻领域拥有70余年技术积累:
RN73H1ETTP1002B25凭借高精度、宽温稳定、小型化等特点,成为小信号电路中替代低精度电阻的优选方案,可满足多领域对电子元器件性能的需求。

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.
