RC-02K3161FT是风华(FH)品牌推出的一款0402封装厚膜贴片电阻,针对小型化、宽温环境下的电子电路设计,具备稳定的电气性能与可靠的环境适应性,广泛应用于消费电子、工业控制等领域。
RC-02K3161FT属于风华被动元件产品线中的通用厚膜贴片电阻,型号命名遵循行业标准:其中“02K”对应0402封装(英制尺寸0.04英寸×0.02英寸,公制约1.0mm×0.5mm),“3161”表示标称阻值3.16kΩ(前三位316为有效数字,第四位1为倍率10¹),“FT”为风华产品系列代码。产品采用厚膜工艺制造,通过丝网印刷、烧结等工序形成电阻膜层,兼顾成本与性能优势。
标称阻值为3.16kΩ,精度等级±1%,即在25℃标准环境下,实际阻值与标称值偏差不超过±31.6Ω,满足多数对阻值精度要求稳定的电路需求(如分压、限流、信号滤波)。
额定功率62.5mW,指环境温度≤+70℃时可长期稳定工作;若温度升高需按降额曲线使用(如+125℃时降额至约20mW),避免过热失效。
温度系数(TCR)±100ppm/℃,表示每变化1℃,阻值变化为标称值的百万分之一(±0.01%/℃)。例如,温度从25℃升至125℃(变化100℃),阻值变化约±3.16Ω(±0.1%),宽温环境下稳定性优异。
覆盖**-55℃~+155℃**,符合工业级、部分汽车级应用的温度要求,可在极端高低温环境长期运行(如北方户外设备、高温工业现场)。
RC-02K3161FT的小型化封装与宽温性能,适用于以下场景:
风华作为国内被动元件龙头,RC-02K3161FT通过以下措施保障可靠性:
RC-02K3161FT凭借小型化、宽温稳定、成本可控的特点,成为小型电子电路替代插件电阻的理想选择,适用于对尺寸、温度适应性有要求的各类场景。
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.
