FRC0402F51R0TS 厚膜贴片电阻产品概述

一、产品定位与核心参数概览

FRC0402F51R0TS是富捷电子(FOJAN)推出的0402封装厚膜贴片电阻,针对小型化、低功耗电子设备的精准电阻匹配需求设计。其核心参数明确且适配主流应用场景:

  • 标称阻值:51Ω
  • 精度等级:±1%(满足多数电路的分压、信号调理精准度要求)
  • 额定功率:62.5mW(适配低功耗设备的功率需求)
  • 最大工作电压:50V
  • 温度系数:±100ppm/℃
  • 工作温度范围:-55℃~+155℃

该产品平衡了成本与性能,是中低端至中端电子设备规模化应用的理想选择。

二、封装与物理特性

采用标准0402贴片封装(尺寸约1.0mm×0.5mm),为当前小型化PCB布局的主流封装之一,可显著提升电路密度,适配自动化SMT生产流程(贴装效率高、兼容性强)。

核心工艺为厚膜电阻技术:通过在氧化铝陶瓷基底上印刷厚膜电阻浆料并高温烧结而成,相比薄膜电阻成本更低,且具备良好的稳定性;相比绕线电阻体积更小,无引线设计减少了寄生参数,提升了电路高频性能。

三、电气性能深度解析

  1. 阻值精度:±1%的精度可满足多数电路的匹配要求(如传感器接口分压、音频电路增益调节),避免因阻值偏差导致的信号失真;
  2. 功率与电压限制:
    • 额定功率62.5mW:实际工作中需同时满足功率与电压阈值,最大电流计算为( I = \sqrt{P/R} ≈ 35mA )(功率限制下的安全电流);
    • 最大工作电压50V:为击穿电压阈值,电路电压需控制在此范围内;
  3. 温度稳定性:±100ppm/℃的温度系数意味着温度每变化1℃,阻值变化±5.1mΩ。在-55℃~+155℃宽温范围内,最大阻值变化率约±2.1%(210℃温差下),实际应用中温度不会同时达到极值,稳定性符合多数场景需求。

四、环境适应性评估

  • 宽温工作能力:-55℃至+155℃的温度范围覆盖工业级、消费电子、部分汽车辅助系统的典型环境(如户外IoT设备、车载显示屏模块);
  • 耐环境可靠性:厚膜电阻结构具备良好的耐湿、耐振动特性,通过常规可靠性测试(湿热循环、振动测试),适合长期运行;
  • 长期稳定性:烧结工艺使电阻膜与基底结合牢固,长期使用中阻值漂移可控,批量生产一致性好。

五、典型应用场景

该电阻的参数特性适配以下场景:

  1. 消费电子:智能手机、平板电脑的传感器接口(加速度计、光线传感器)、音频电路分压电阻;
  2. 工业控制:小型PLC、传感器模块的限流电路、信号调理电路;
  3. 物联网设备:低功耗IoT节点的滤波电路、电阻匹配网络;
  4. 小型电源:DC-DC转换电路反馈电阻、LDO输出分压电阻;
  5. 汽车电子(辅助系统):车载中控背光调节、胎压监测信号处理电路(常规工业级,需确认具体车规场景兼容性)。

六、品牌与品质保障

富捷电子(FOJAN)是国内专注被动元件研发生产的厂商,FRC0402F51R0TS符合RoHS、REACH环保指令,批量供货稳定。产品通过高温存储、温度循环等可靠性测试,适合OEM/ODM厂商规模化应用,同时提供完善的技术支持与售后保障。

总结

FRC0402F51R0TS凭借精准阻值控制、宽温适应性和紧凑封装,成为小型化电子设备中信号调理、分压限流场景的高性价比选择,平衡了性能与成本,满足多数中端应用的可靠性需求。

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
