FRC0402F1910TS 产品概述(FOJAN 富捷)

一、产品简介

FRC0402F1910TS 是 FOJAN(富捷)推出的一款0402封装厚膜贴片电阻,标称阻值为191Ω,精度±1%,额定功率62.5mW,额定工作电压标示为50V,温度系数(TCR)为±100ppm/℃,工作温度范围为-55℃至+155℃。该元件适用于空间受限的高密度电路板,兼顾成本与稳定性,常用于移动设备、消费电子与各类信号处理电路中。

二、电性能要点与计算说明

  • 阻值:191Ω,公差±1%,适合精度要求较高的分压、偏置和反馈网络。
  • 额定功率:62.5mW。按额定功率计算的连续工作电流与电压如下:
    • 最大安全直流电流(不超额定功率):Imax ≈ sqrt(P/R) ≈ 18.1mA。
    • 对应最大电压:Vmax = Imax × R ≈ 3.46V。
  • 标称“工作电压50V”为器件在结构或绝缘上的最大允许电压值,但在实际应用中必须同时满足功率限制。切勿直接在191Ω上施加接近50V的电压,否则会远超功率上限导致损坏。
  • 温度系数±100ppm/℃,中等温漂,适用于对温度敏感但允许一定漂移的电路。

三、封装与机械特性

  • 封装:0402(约1.0mm × 0.5mm)贴片形式,适合自动贴装与回流焊工艺。
  • 厚膜工艺特点:成本低、批量一致性好,耐焊接热冲击能力强。与金属膜相比TCR和噪声略逊,但在大多数消费类与工业控制场景足够使用。
  • 一般采用带卷(tape & reel)包装,便于SMT贴片生产线使用。

四、可靠性与使用建议

  • 温度范围广(-55℃~+155℃),适合多数严苛环境。但高温下建议按厂家热耗降额/曲线进行降额使用。
  • 建议在长期与稳定性要求场合中,实际工作功率保守设计(例如不超过额定功率的70%),以提升寿命与可靠性:0.7×62.5mW ≈ 43.8mW,对应约15mA、2.9V。
  • 若需更高功率或更低温漂,可采用并联电阻或选用更高功率/更低TCR的系列产品。

五、应用场景

  • 精密分压与电压检测电路(需±1%精度)。
  • 移动终端与可穿戴设备中的限流、电平设定。
  • 信号调理、滤波阻抗匹配、电阻网络模块。
  • 工业传感与低功率模拟电路。

六、设计与焊接提示

  • 遵循常规SMT回流焊曲线与PCB焊盘设计规范(参考IPC标准),避免长时间高温。
  • PCB布局中为减少热集中,应注意散热路径与相邻元件的热影响,必要时留出热隔离区。
  • 如果电路可能承受较高瞬态电压或冲击,应在电路设计层面增加限压、限流保护,切勿仅凭器件标称“工作电压”作为保护依据。

总结:FRC0402F1910TS 以其0402超小封装、±1%精度和中等温漂特性,适合对空间、成本与精度有综合要求的低功耗电路。设计时务必兼顾额定功率与最大电压的差异,按场景做合理降额与热管理,以确保长期可靠运行。若需更详细的焊接曲线、包装信息或样品测试数据,建议联系FOJAN(富捷)官方获取完整技术资料和数据手册。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
