FRC0402F2493TS 产品概述

一、产品简介

FRC0402F2493TS 为 FOJAN(富捷)系列厚膜贴片电阻,封装为 0402(公制 1005),阻值 249 kΩ,精度 ±1%,额定功率 62.5 mW,最高工作电压 50 V。该器件采用厚膜工艺制造,具有良好的批量一致性和成本优势,适用于高阻值、低功耗的表面贴装电路中,工作温度范围宽(-55 ℃ ~ +155 ℃),温度系数(TCR)为 ±100 ppm/℃,能满足多种精密电子应用中对阻值稳定性和温度漂移的要求。

二、主要参数

  • 电阻类型:厚膜电阻(Chip Resistor, Thick Film)
  • 封装:0402(公制 1005)
  • 阻值:249 kΩ
  • 精度:±1%(F 等级)
  • 额定功率:62.5 mW(0.0625 W)
  • 最大工作电压:50 V(工作时请按额定与降额使用)
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 品牌:FOJAN(富捷)

三、产品特点

  • 小体积封装:0402 尺寸适合高密度贴片组装,节省 PCB 面积。
  • 高阻值稳定性:249 kΩ ±1% 的阻值精度适用于需要较高阻值和较好精度的电路。
  • 宽温度范围和可控温漂:工作温度范围宽,TCR ±100 ppm/℃ 在普通环境温度变化下保持较好一致性。
  • 适用无铅回流工艺:厚膜电阻可适应常见的无铅回流焊工艺,便于 SMT 流程集成。
  • 成本与性能平衡:厚膜工艺在成本、可制造性上具备优势,适合大批量应用。

四、典型应用场景

  • 精密电阻分压网络与基准电路(高阻值场合的输入偏置/上拉/下拉)
  • 模拟前端:运放偏置、滤波器时间常数设定、电平检测电路
  • 低功耗与便携设备:电流极小的信号处理与传感器接口
  • 测量与数据采集系统:ADC 输入网络、采样保持电路的阻容设定
  • 工业控制、仪表、通信终端和物联网模块等对空间与成本敏感的应用

五、装配与焊接建议

  • 回流焊:推荐采用符合 J-STD-020 的回流曲线,控制峰值温度与时间以避免对元件可靠性造成影响。通常 0402 元件适配的无铅回流峰值温度在 245–260 ℃ 区间(具体请参照工厂工艺规范)。
  • 握持与贴装:使用适配 0402 的真空吸嘴或夹具,避免侧压或过度弯曲。贴片元件在高速贴装时注意防止翻转或偏位。
  • 清洗与残留物处理:高阻值器件对表面污染较敏感,建议对焊后清洗残留助焊剂并控制清洗剂的导电或残留物,避免造成漏电或阻值漂移。
  • ESD 防护:高阻值电阻对静电可能敏感,生产与装配环境应采取静电防护措施。
  • 降额使用:为保证长期可靠性,建议在使用时对功率和电压适当降额(例如工作电压低于额定最大值、功率低于额定功率的 70–80%),尤其在高温环境下应进一步考虑热降额。

六、可靠性与储存

  • 工作温度范围 -55 ℃ ~ +155 ℃,在本范围内长期工作需注意环境温度对阻值漂移的影响。
  • 储存条件建议:常温、干燥、避免直射日光与化学污染;湿度控制在 75% 以下并避免潮湿环境以防潮湿吸收。
  • 包装:常见为卷盘(Tape & Reel)包装,便于 SMT 自动化贴装;带宽通常为 8 mm,常见卷轴尺寸有 7 英寸或 13 英寸,以客户需求为准。

七、型号说明与订购提示

  • 型号 FRC0402F2493TS 可拆解为系列(FRC)+ 封装(0402)+ 精度代码(F 表示 ±1%)+ 阻值编码(2493 表示 249 × 10^3 Ω = 249 kΩ)+ 包装/特殊代码(TS 表示卷盘/包装或厂内编码)。
  • 订购时请确认:阻值与精度、封装、包装方式(卷盘长度)、是否需要特殊检验或气候等级要求。若用于关键应用场合,建议索取元件的规格书与质量认证(如需),并进行来料检验或样件评估。

八、注意事项

  • 高阻值器件对表面污染和机械应力较敏感,设计与生产环节应做好清洁与应力控制。
  • 在高阻值电路设计中应考虑寄生泄漏路径、焊膏残留、电介质吸潮对阻值的影响。
  • 如有更高精度或更低 TCR 的需求,可咨询供应商或选用薄膜/金属膜等更高精度的替代品。

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
