RC-02K5901FT是风华高科(FH)推出的通用精密厚膜贴片电阻,专为小体积、高密度表面贴装电路设计,兼顾精度与可靠性,适配多场景低功耗应用。其核心参数如下:
RC-02K5901FT采用0402表面贴装封装,物理尺寸为:长度≈1.0mm,宽度≈0.5mm,厚度≈0.3mm(典型值)。该封装具备以下优势:
标称阻值5.9kΩ,25℃参考温度下,阻值偏差控制在5841Ω~5959Ω(±1%)范围内,可满足分压电路、运算放大器反馈回路等对阻值误差敏感的应用;结合±100ppm/℃的温度系数,当环境温度从25℃变化至125℃(温差100℃)时,阻值变化量≤±59Ω(即±1%),保障宽温环境下电路性能的一致性。
额定功率62.5mW,实际应用需遵循降额原则(如环境温度每升高10℃,功率降额约10%)。根据公式 ( V=\sqrt{P×R} ),其最大工作电压约为19.2V,可满足低电压电路的供电与信号处理需求。
RC-02K5901FT的工作温度范围覆盖-55℃+155℃,远超常规商业级(0℃70℃)与工业级(-40℃~125℃)标准,可适配:
RC-02K5901FT因体积小、精度适中、宽温稳定,广泛应用于以下领域:
风华高科(FH)是国内被动元件行业龙头,RC-02K5901FT具备以下质量优势:
综上,RC-02K5901FT是一款高性价比的精密厚膜贴片电阻,适配多场景低功耗、宽温环境的电路设计需求,是电子设备小型化、可靠性升级的优选元件。
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.
