RC-02K9531FT是FH(风华)电子推出的0402封装高精度厚膜贴片电阻,针对小型化、高密度电子电路设计,兼顾精准度、稳定性与环境适应性,广泛适配消费电子、工业控制、通信等领域的低功耗电路需求。
RC-02K9531FT属于风华厚膜贴片电阻系列的经典型号,核心定位为小尺寸、高精度、宽温域的通用型贴片电阻:
该型号的核心参数直接决定了其应用边界,各参数的实际意义如下:
阻值为9.53kΩ,精度等级±1%——这意味着在25℃基准温度下,电阻实际阻值偏差不超过95.3Ω,可满足大多数模拟电路(如运算放大器反馈、传感器信号放大)对阻值精准度的要求,无需额外校准。
额定功率62.5mW(0.0625W),是0402封装厚膜电阻的典型功率等级。实际应用中建议采用80%功率降额(即实际功耗不超过50mW),可有效避免长期过载导致的阻值漂移或热失效,适配低功耗设备(如IoT终端、可穿戴设备)。
温度系数为**±100ppm/℃**——换算为实际阻值变化:当环境温度从25℃变化到125℃(温差100℃)时,阻值变化幅度仅±0.1%(9.53kΩ×100ppm×100℃=±9.53Ω)。这一特性可大幅降低温度波动对电路性能的影响,适合户外设备、工业现场等温度变化较大的场景。
覆盖**-55℃+155℃**的宽温域,符合工业级电子元器件的温度要求(通常工业级为-40℃+125℃,该型号超出此范围,可适配更严苛的环境),可用于汽车电子辅助电路、户外传感器节点等场景。
RC-02K9531FT采用0402厚膜贴片封装,其工艺与封装特性决定了性能稳定性:
采用丝网印刷+高温烧结的厚膜工艺:
RC-02K9531FT的参数特性使其适配多个领域的低功耗电路:
风华作为国内老牌电子元器件厂商,RC-02K9531FT的可靠性经过多重测试验证:
符合RoHS 2.0(无铅、无镉、无汞)、REACH等环保标准,适配全球市场需求。
为确保电路可靠性,使用时需注意以下要点:
实际工作功率建议不超过额定功率的80%(即≤50mW),避免长期过载导致阻值漂移;若环境温度超过85℃,需进一步降低功率(如60%降额)。
RC-02K9531FT凭借小尺寸、高精度、宽温域与高可靠性,成为小型化电子电路的理想选择,可满足从消费电子到工业控制的多样化需求。
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.
