RC-01W2103FT是风华电子(FH)推出的0201封装厚膜片式电阻,核心参数如下:
厚膜工艺优势
采用高纯度氧化铝陶瓷基板,通过印刷电阻浆料、烧结、激光调阻成型,兼具成本优势与稳定性能:相比薄膜电阻更适合批量生产,相比碳膜电阻温度系数更低、耐功率更好。
精度与温度稳定性
±1%精度可满足大多数电子电路的电阻匹配(如信号分压、偏置电路);±200ppm/℃温度系数意味着:温度变化100℃时,阻值波动≤±2.1kΩ(即±1%以内),全温度范围(-55~125℃)阻值变化≤±3.6%,适配极端温度场景。
小体积高密度适配
0201封装仅为0.6mm×0.3mm,可大幅节省PCB空间,满足便携式设备(如手机、智能手表)的轻薄化设计需求。
便携式智能设备
智能手机、蓝牙耳机、智能手表的音频信号分压、射频匹配电路:小体积适配设备内部高密度PCB布局,低功耗满足续航要求。
工业传感器接口
温度传感器(PT100、NTC)、压力传感器的信号放大偏置电路:宽温度范围(-55~125℃)可适应工业现场的极端温差(如户外设备、车间高温环境)。
物联网低功耗模块
WiFi、蓝牙、LoRa无线模块的电源滤波、基准电压分压:50mW额定功率适配低功耗设计,避免功率浪费。
汽车电子辅助电路
车载信息娱乐系统的按键背光分压、传感器辅助电路:工作温度覆盖汽车级环境(-40℃低温启动、100℃以上高温工作)。
消费电子电源网络
电视机、机顶盒的电源滤波网络、LED驱动偏置电路:成本优势与稳定性能适配大规模生产。
极端温度耐受
-55℃~+125℃工作范围符合工业级标准,长期工作无阻值漂移(风华内部测试:1000小时高温老化后,阻值变化≤±0.5%)。
耐环境性能
玻璃釉保护层可抵御潮气、灰尘与化学腐蚀:通过85℃/85%RH湿热试验(1000小时)后,阻值变化≤±1%,适配潮湿、多尘场景。
焊接可靠性
端电极采用镍-锡镀层,与PCB焊盘附着力强:回流焊(245±5℃,10秒内)、波峰焊(250±5℃,3秒内)无虚焊、脱落问题。
功率降额
实际工作功率建议≤25mW(额定功率的50%),延长产品寿命,避免过载导致阻值漂移。
电压限制
电路电压不得超过25V,若电压较高需串联/并联电阻分压,防止击穿。
焊接规范
遵循风华工艺参数:回流焊峰值温度240250℃(时间≤10秒),波峰焊温度245255℃(时间≤3秒),避免高温损伤。
存储条件
未焊接产品存储在1535℃、4060%湿度环境,存储周期≤12个月,避免受潮。
替换原则
替换需匹配:阻值(210kΩ)、精度(±1%)、温度系数(±200ppm/℃)、封装(0201)、功率(≥50mW),防止电路性能下降。
RC-01W2103FT凭借小体积、稳定性能与宽温度范围,成为工业、消费电子、物联网等领域的高性价比片式电阻选择。
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.
