FOJAN FRC0402F4300TS 厚膜贴片电阻产品概述

一、产品基本信息

FOJAN(富捷)FRC0402F4300TS是一款针对高密度集成设计的厚膜贴片电阻,型号命名遵循行业通用逻辑:

  • 「FRC」为厚膜电阻系列标识;
  • 「0402」对应英制封装尺寸(公制1.0mm×0.5mm×0.5mm,典型厚度);
  • 「4300」表示阻值430Ω(后两位为倍率,430×10⁰=430Ω);
  • 「TS」为精度及温度系数组合标识。

该产品以陶瓷基板为载体,采用厚膜印刷工艺制造,适配回流焊、波峰焊等常规贴片工艺,适合对空间、功率密度要求严格的电子电路。

二、核心性能参数详解

  1. 阻值与精度:标准阻值430Ω,精度±1%,满足大多数电路的信号匹配、分压、限流需求,无需额外校准即可实现稳定电气性能;
  2. 功率与电压:额定功率62.5mW(即1/16W),最大工作电压50V,常规工作条件下可长期稳定运行,避免功率过载烧毁;
  3. 温度特性:温度系数(TCR)±100ppm/℃(每℃阻值变化≤±0.01%),工作温度范围覆盖-55℃至+155℃,可适应低温户外、高温工业等极端环境;
  4. 封装尺寸:0402小封装体积,适配手机、智能穿戴、小型工业模块等对PCB空间敏感的产品。

三、工艺与可靠性优势

该产品采用厚膜丝网印刷工艺,核心流程为:氧化铝陶瓷基板→钌系电阻浆料印刷→高温烧结→终端电极制作(银钯合金+镍镀层)。此工艺带来三大优势:

  • 稳定性强:陶瓷基板热膨胀系数低,电阻膜与基板结合紧密,长期使用阻值漂移极小;
  • 成本可控:相较于薄膜电阻,厚膜工艺成本更低,适合批量应用;
  • 抗环境能力:厚膜电阻膜致密,抗潮湿、抗腐蚀能力优于薄膜电阻,可在工业、户外等复杂场景可靠工作。

四、典型应用场景

FRC0402F4300TS因小封装、宽温范围、稳定精度等特点,广泛应用于以下领域:

  1. 消费电子:智能手机、平板的电源管理电路(分压检测、限流保护)、音频信号调理电路;
  2. 工业控制:小型PLC的I/O接口、传感器信号放大电路、微型电机驱动辅助电路;
  3. 通信设备:路由器、交换机的射频前端匹配网络、电源滤波电路;
  4. 车载辅助电路:车载USB充电模块、仪表盘背光电路(宽温范围可满足部分非关键车载场景)。

五、使用注意事项

为确保性能与可靠性,使用时需注意:

  1. 功率降额:实际功率不超过62.5mW,环境温度>70℃时需按温度系数降额(如125℃时,最大允许功率约为额定值的70%);
  2. 电压限制:工作电压不得超过50V,避免电阻膜击穿;
  3. 焊接工艺:回流焊峰值温度控制在240℃-250℃(时间≤30s),避免高温损伤电阻;
  4. 静电防护:遵循ESD规范,避免静电损伤终端电极(虽抗静电能力优于薄膜电阻,但仍需防护)。

六、产品总结

FOJAN FRC0402F4300TS厚膜贴片电阻平衡了小封装、稳定精度、宽温范围与成本,是消费电子、工业控制、通信等领域的高性价比选择。其厚膜工艺适配批量集成需求,可有效提升电路空间利用率与长期稳定性,适合对性能要求中等、成本敏感的应用场景。

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
