FRC0402F4533TS是FOJAN(富捷) 推出的0402封装厚膜贴片电阻,属于小型化、高精度通用电阻系列,专为高密度电路设计需求打造,兼顾精度、体积与成本平衡。
型号字符解析:
标称阻值453kΩ,采用E96系列阻值编码(工业1%精度电阻通用标准),精度±1%,满足多数电路对阻值一致性的要求,可避免因电阻偏差导致的信号失真或控制误差。
公制尺寸1.0mm(长)×0.5mm(宽)×0.3mm(高),体积仅为0603封装的1/4,可显著减少PCB面积占用。
采用丝网印刷+高温烧结工艺制备电阻膜,膜层附着力强、稳定性高,长期使用无明显阻值漂移;电阻膜与陶瓷基底结合紧密,抗机械冲击能力优于薄膜电阻。
三层端电极结构(镍层+锡层+保护层),兼容无铅回流焊工艺,焊接强度高(避免虚焊/脱落);端电极尺寸匹配0402封装,与PCB焊盘贴合性好。
0402封装体积适合便携设备(如智能手机、智能穿戴)的高密度布局,可提升电路集成度。
智能手机/平板的信号调理电路(音频滤波、传感器接口)、智能穿戴的低功耗控制电路(心率监测分压)。
PLC输入输出接口、传感器(温度/压力)信号放大电路、小型工业电源的分压反馈电路。
小型基站/路由器的射频辅助电路(信号衰减、阻抗匹配)、光纤收发器的偏置电路。
车载仪表盘背光控制电路、胎压监测模块的信号处理电路(温度范围覆盖部分车载环境)。
-55℃~+155℃宽温范围+±100ppm/℃温度系数,极端温度下阻值波动极小,避免电路性能波动。
厚膜电阻膜层抗潮湿、抗盐雾能力优于薄膜电阻,适合户外设备或高湿度环境(如农业物联网传感器)。
老化测试后阻值漂移≤0.5%(典型值),端电极焊接寿命≥1000小时(回流焊循环),满足批量生产与长期使用需求。
实际使用功率建议不超过额定功率的50%(即31.25mW),避免过热导致阻值漂移;电压需优先满足(U≤50V)。
无铅回流焊温度曲线需符合IPC标准(峰值230℃250℃,回流时间3060秒),避免过温损坏电阻膜。
未开封产品存储于15℃35℃、湿度40%60%环境,开封后12个月内使用完毕(避免端电极氧化)。
±1%精度适合中等精度需求,若需更高精度(如计量电路),需选用±0.1%/±0.5%电阻。
该产品凭借小型化、高精度与宽温适应性,成为消费电子、工业控制等领域的高性价比选择。

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.
