RC-02K9091FT是风华电子(FH) 推出的厚膜贴片电阻,属于该品牌常规高精度贴片电阻系列。型号各部分含义清晰:
该产品采用厚膜工艺制造,兼顾成本与性能,适用于多场景批量应用。
注:功率与电压需同时满足(如9.09kΩ电阻在50V下的功率为50²/9090≈274mW,远大于额定功率,实际使用需按功率降额)。
0402封装尺寸紧凑(约1.0mm×0.5mm×0.4mm),可显著节省PCB布局空间,适配便携式设备、小型模块的高密度集成需求。
采用丝网印刷+高温烧结工艺:
±100ppm/℃的TCR在厚膜电阻中属中等偏优:
符合IEC 60068-2-67(恒定湿热)标准,在40℃、93%RH环境下仍能保持电气性能稳定,适配潮湿地区或户外设备。
RC-02K9091FT因小封装、高精度与宽温特性,主要应用于:
⚠️ 注意:额定功率62.5mW,不适用于高功率电路(如功率放大、电源输出端),仅适合信号级/低功耗场景。
风华电子(FH)是国内被动元件龙头企业,RC-02K9091FT具备:
该产品经多项可靠性测试(如温度循环、振动),可支撑客户大规模量产需求。
综上,RC-02K9091FT是一款高性价比、小体积、宽温稳定的厚膜贴片电阻,适配多数小型化电子设备的常规电路设计。
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.
