FRC0402F3902TS 厚膜贴片电阻产品概述

一、核心电气与规格参数

FRC0402F3902TS为厚膜贴片电阻,核心参数适配中精密小功耗电路需求:

  • 阻值与精度:采用E96系列编码3902,对应实际阻值39kΩ,精度等级±1%,可满足多数电路的阻值匹配要求(如传感器信号调理、电源分压);
  • 功率与电压:额定功率62.5mW(25℃环境下),最大工作电压50V,覆盖常见低压直流/交流电路(如5V、12V系统),避免过压损坏;
  • 温度特性:温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值变化≤3.9Ω,结合**-55℃~+155℃宽温范围**,可稳定应对工业/汽车等极端环境;
  • 工艺类型:厚膜印刷烧结工艺,膜层均匀性优于碳膜电阻,抗浪涌能力更强。

二、封装与物理尺寸

该产品采用0402英寸贴片封装(公制尺寸1.0mm×0.5mm),是贴片电阻中尺寸较小的规格之一:

  • 适配高密度PCB设计,可有效节省空间(如智能手机、可穿戴设备的小型化需求);
  • 焊盘符合IPC标准,兼容自动化贴装设备(如富士、西门子贴片机),支持高速批量生产,降低组装成本;
  • 封装厚度约0.3mm,适配薄型PCB板,满足轻薄化电子设备要求。

三、性能特点

  1. 宽温稳定性:±100ppm/℃ TCR与-55~155℃工作温度,可在极端环境下保持阻值稳定(如北方户外设备、汽车发动机舱附近模块);
  2. 抗干扰与可靠性:厚膜工艺使电阻膜层与陶瓷基体结合牢固,抗湿性、抗腐蚀性优于薄膜电阻,可承受瞬间脉冲电压冲击(如电源启动时的浪涌);
  3. 成本效益:厚膜工艺成熟,价格低于金属膜精密电阻,同时精度满足中高端应用,性价比突出;
  4. 环保合规:符合RoHS无铅环保要求,适配绿色电子产品设计(如欧盟市场准入需求)。

四、典型应用场景

该产品参数特性使其广泛覆盖以下领域:

  1. 消费电子:智能手机/平板的电源管理模块(分压采样、滤波)、音频电路(信号衰减)、可穿戴设备(心率传感器信号调理);
  2. 汽车电子:车载低压控制单元(车身控制器信号调理)、仪表盘背光电路(限流)、胎压监测模块(信号分压);
  3. 工业控制:PLC输入输出接口(信号匹配)、温度传感器放大电路(分压)、小型电机驱动电路(限流);
  4. 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、光纤收发器信号调理。

五、可靠性与质量保障

  1. 环境适应性:厚膜电阻膜层抗老化性能优异,长期使用阻值漂移≤0.5%(1000小时高温老化后);
  2. 功率降额:实际应用需根据环境温度降额(如125℃时降额至约31mW),确保长期可靠性;
  3. 品牌背书:由FOJAN(富捷)生产,该厂商专注厚膜电阻研发10余年,通过ISO9001与IATF16949认证,产品供货稳定,支持定制化阻值/封装。

FRC0402F3902TS以小体积、宽温稳定、高性价比的特点,成为中精密小功耗电路的优选厚膜贴片电阻,可满足多领域电子设备的集成需求。

Sourcing availability signal

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
