FRC0402F9R10TS 产品概述
一、产品简介
FRC0402F9R10TS 为 FOJAN(富捷) 出品的 0402 封装厚膜贴片电阻，标称阻值 9.1Ω，允许偏差 ±1%，额定功率 62.5mW，标称工作电压 50V，温度系数 TCR ±400ppm/℃，工作温度范围 -55℃ 至 +155℃。该型号适用于对体积和精度有一定要求的高密度贴片电路。
二、主要特性
- 小尺寸：0402（约 1.0mm × 0.5mm）适合高密度板面布局与微型化产品。
- 较高精度：±1% 满足常规精密分压、偏置和滤波网络需求。
- 宽温度范围及工业级工作温度，适合多种恶劣环境。
- 厚膜工艺成本效益好，可靠性稳定，RoHS 兼容（视具体批次认证）。
三、性能与计算提示
- 功率限制决定实际使用时跨端电压与电流：按功率 P=I^2R，可得持续允许电流约 Imax = sqrt(0.0625/9.1) ≈ 0.083A（≈83mA），对应跨端电压 V = I·R ≈ 0.75V。虽然标注工作电压为 50V，但在实际电路中应以功耗限制为准，避免局部过热烧毁。
- 温度系数 ±400ppm/℃ 对 9.1Ω 而言，温度每变化 1℃ 阻值变化约 0.00364Ω；极端温度变化会带来显著阻值漂移，设计时应考虑热漂移影响。
四、典型应用场景
- 移动设备、可穿戴与物联网终端的偏置与限流电路；
- 信号调理、分压和小电流检测（注意功率限制）；
- 高频滤波网络与阻尼元件、表贴原型与批量生产均适用。
五、封装与装配建议
- 推荐采用回流焊工艺，注意温度曲线符合厚膜电阻回流规范；
- 0402 体积微小，贴装时避免过大的机械压力与刮擦，焊膏量与焊盘设计需匹配以防虚焊或桥连；
- 常见为卷盘（Tape & Reel）供货，适合自动贴片加工。
六、可靠性与存储注意事项
- 避免长时间潮湿、高温或酸碱环境存放，开封后尽快使用；
- 应避免超额定功率与电流冲击，焊接后如需清洗选择对厚膜元件安全的溶剂与工艺。
总结：FRC0402F9R10TS 在体积与精度之间提供了良好折中，适合对空间敏感且对阻值精度有要求的电子产品设计；但由于功率较低，实际应用中应严格按功耗和温漂计算选择与布局，以保证长期可靠性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
