FRC0402F4992TS 贴片厚膜电阻产品概述

一、产品核心定位

FRC0402F4992TS是富捷电子(FOJAN) 推出的一款0402封装贴片厚膜电阻,定位于小功率、高精度、工业级温度适应性的通用型电阻器件。其采用成熟厚膜工艺制造,兼顾成本控制与性能稳定性,广泛适配消费电子、工业控制、汽车电子等多领域的基础电路需求,是替代同规格进口电阻的高性价比选择。

二、关键电气性能参数详解

1. 阻值与精度

标称阻值为49.9kΩ(即49900Ω),精度等级±1%——满足大多数信号调理、分压电路对阻值偏差的要求,无需额外校准即可实现稳定的电路参数输出,避免因阻值偏差导致的信号失真。

2. 功率容量

额定功率62.5mW(0.0625W)——适用于小电流信号路径(如偏置电路、传感器接口),避免功率冗余带来的成本浪费,同时保证在低功耗场景下的长期可靠性。

3. 工作电压

最大持续工作电压50V——结合阻值计算,50V下工作电流约1mA,功率消耗约0.05W(低于额定功率),可在安全范围内长期运行,无需额外降额设计。

4. 温度系数

温度系数为**±100ppm/℃**——温度每变化1℃,阻值变化±0.01%;在-55℃~+155℃全温区,阻值最大漂移约±2.1%,满足工业级环境的温度波动需求(如户外设备、车载高温场景)。

5. 工作温度范围

覆盖**-55℃+155℃**——超出常规商业级(0℃70℃)器件的温度范围,可适配极端低温(如北方户外监控)、高温(如发动机舱附近)场景,符合工业级器件的核心标准。

三、封装与工艺特性

1. 封装尺寸

采用0402封装(英制)/1005封装(公制)——长度1.0mm、宽度0.5mm,小体积适配高密度PCB设计(如智能手机主板、小型工业模块),有效节省电路板空间,支持多器件密集布局。

2. 厚膜工艺优势

  • 以陶瓷基底为载体,印刷厚膜电阻浆料后高温烧结而成,相比薄膜电阻成本更低;
  • 具备较好的抗冲击、抗振动性能,适合批量生产中的可靠性要求(如汽车电子的振动环境);
  • 电阻膜层均匀性好,阻值一致性高,批量产品偏差可控。

3. 焊接兼容性

引脚焊盘设计符合行业标准,兼容回流焊、波峰焊等常规贴片加工工艺,可直接集成于自动化生产流程,无需特殊设备适配。

四、典型应用场景

1. 消费电子领域

  • 智能手机、平板的信号调理电路(如音频偏置电阻、射频前端分压);
  • 智能穿戴设备的传感器接口限流(如心率传感器、加速度计的辅助电阻)。

2. 工业控制领域

  • PLC(可编程逻辑控制器)的输入输出接口电阻;
  • 温度传感器、压力传感器的信号放大偏置电路;
  • 小型工业模块的电源分压网络。

3. 汽车电子领域

  • 车载仪表盘的小信号处理电路;
  • 车身传感器(如胎压监测、水温传感器)的辅助电阻(适配-40℃~+85℃车载环境)。

4. 通信设备领域

  • 路由器、基站的射频辅助电路;
  • 光纤收发器的信号分压电阻;
  • 小型通信模块的电源滤波网络。

5. 医疗设备领域

  • 小型家用医疗仪器(如血糖仪、血压计)的基础电路;
  • 便携式医疗设备的信号调理电路(宽温区适配医用环境的温度变化)。

五、品牌可靠性与合规性

富捷电子(FOJAN)作为国内电阻制造领域的资深厂商,FRC0402F4992TS具备以下优势:

  • 环保合规:通过RoHS、REACH认证,符合欧盟及国内电子电器产品的环保要求;
  • 可靠性测试:经过高温老化、振动测试、湿度测试等多重可靠性验证,在额定参数下长期工作无明显性能漂移;
  • 批量一致性:采用自动化生产流程,批量产品阻值偏差、温度系数一致性高,可满足量产项目的稳定性需求。

综上,FRC0402F4992TS是一款性能均衡、成本可控的通用贴片厚膜电阻,可广泛应用于多领域的基础电路设计,是工程师优化电路方案的可靠选择。

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
