FRC0204F2491TS 厚膜贴片电阻产品概述

FRC0204F2491TS是FOJAN(富捷)推出的一款小型化厚膜贴片电阻,专为高密度、宽温环境下的电子电路设计,核心聚焦“精度适配+成本可控+环境耐受”三大需求,广泛应用于消费电子、工业控制、汽车电子等领域。

一、产品核心定位与基本属性

该产品属于FOJAN FRC系列0402封装电阻,采用厚膜陶瓷工艺(氧化铝基底),兼顾“小体积”与“可靠性”,针对中精度(±1%)、低功率(≤62.5mW)场景优化,是替代传统插件电阻、提升电路集成度的主流选择。

二、关键电气性能参数详解

2.1 阻值与精度

  • 标称阻值:2.49kΩ(E-96系列阻值编码“2491”,即249×10¹=2490Ω);
  • 精度等级:±1%(符合工业级电阻的常见精度要求),阻值一致性可满足信号分压、滤波、基准电压电路的直接使用,无需额外校准。

2.2 功率与电压额定值

  • 额定功率:62.5mW(0.0625W),适用于低功耗信号电路(如传感器输出调理、LED小电流驱动);
  • 额定电压:50V(绝对最大电压限制),实际工作需同时满足:
    ① 电压≤50V;② 功率P=U²/R≤62.5mW(2.49kΩ下最大工作电压约12.5V),避免过压或过功率损坏。

2.3 温度特性与工作范围

  • 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化±0.01%;若环境温度变化100℃(如-55℃→+45℃),阻值漂移≤1%,仍在精度范围内;
  • 工作温度范围:-55℃+155℃,覆盖工业级(-40+85℃)、汽车级(-55~+125℃),甚至部分高温工业场景(如电机附近、高温传感器)。

三、封装与物理特性

3.1 封装尺寸

采用0402封装(英制代码,对应公制尺寸1.0mm×0.5mm×0.4mm),是贴片电阻中最小的常规封装之一,适合手机、智能穿戴、小型PLC等高密度布局的电路设计。

3.2 工艺特点

厚膜工艺通过“丝网印刷电阻浆料→高温烧结→电极制作”完成,相比薄膜电阻成本更低,相比碳膜电阻稳定性更好,抗机械振动、耐湿性能突出。

四、典型应用场景

4.1 消费电子领域

  • 手机/平板:主板LED背光分压电阻、音频信号滤波电阻、电池保护电路检测电阻;
  • 智能穿戴:智能手表心率传感器信号调理电阻、低功耗蓝牙模块匹配电阻。

4.2 工业控制领域

  • PLC输入模块:数字量输入信号分压电阻(宽温适配现场环境);
  • 传感器接口:温度传感器(如PT100)信号放大电路的偏置电阻。

4.3 汽车电子领域

  • 仪表盘背光:LED驱动分压电阻(-55~+155℃符合车载环境);
  • 车身控制器:小信号开关电路的限流电阻(抗振动、耐温)。

4.4 通信设备

  • 射频前端:低噪声放大器(LNA)的匹配电阻(0402封装适配高密度RF模块)。

五、可靠性与品质保障

5.1 可靠性测试

  • 高温负载测试:125℃、额定功率下工作1000小时,阻值漂移≤0.1%;
  • 温度循环测试:-55℃→+155℃(循环100次),无开路/短路,阻值变化≤0.2%;
  • 耐湿测试:85℃/85%RH环境下1000小时,阻值漂移≤0.3%。

5.2 认证与标准

  • 符合RoHS 2.0、REACH环保标准;
  • 汽车级产品通过IATF 16949认证,工业级通过ISO 9001认证;
  • 静电防护能力:符合IEC 61000-4-2(接触放电±8kV,空气放电±15kV)。

六、供货与定制支持

  • 常规库存:月产能5000万只,常规订单3-5天发货;
  • 定制服务:支持调整精度(如±0.5%)、功率(如1/10W)、阻值(如2.47kΩ)等参数,定制周期15-20天;
  • 包装方式:卷盘包装(每盘5000只),适合SMT自动贴装。

总结:FRC0204F2491TS凭借“小体积、宽温、中精度、高性价比”的特点,成为众多电子设备中小信号电路的优选电阻,可有效降低电路布局空间、提升集成度,同时满足恶劣环境下的长期稳定运行需求。

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
