FRL0402FR500TS 厚膜贴片电阻产品概述

一、产品定位与核心特征

FRL0402FR500TS是富捷电子(FOJAN)针对小型化低功耗电子设备推出的0402封装厚膜贴片电阻,核心聚焦“高精度小阻值+宽温适应性”,是替代传统插件电阻、满足紧凑PCB布局的理想选择。其核心特征可总结为:

  1. 封装紧凑:采用0402标准贴片封装(尺寸约1.0mm×0.5mm),适配高密度电路设计;
  2. 阻值精准:固定阻值500mΩ(0.5Ω),精度达±1%,满足信号调理、小电流采样需求;
  3. 宽温稳定:温度系数(TCR)±300ppm/℃,工作温度覆盖-55℃至+155℃,适应极端环境;
  4. 低功耗设计:额定功率62.5mW(0.0625W),符合便携设备“低功耗”核心要求;
  5. 高耐压:额定工作电压100V,兼顾高阻场景下的电压承载能力。

二、关键电气参数详解

该电阻的电气性能经严格测试验证,核心参数如下:

  • 阻值与精度:固定阻值500mΩ,精度±1%(实际阻值范围495mΩ~505mΩ)。结合TCR计算,温度从25℃升至125℃时,阻值变化约±0.03%,总误差控制在±1.03%以内,满足多数低精度要求的电路设计;
  • 功率与电流:额定功率62.5mW,根据公式(I=\sqrt{\frac{P}{R}}),最大允许电流约0.35A,适合小电流回路的限流、采样;
  • 工作电压:额定电压100V,但实际使用需以“功率不超62.5mW”为核心限制(若电压达100V,功率将达20W,远超额定值);
  • 温度特性:TCR±300ppm/℃,属于厚膜电阻常规范围,相比薄膜电阻成本更低,适配对温度稳定性要求不苛刻的场景。

三、物理与环境适应性

3.1 封装与工艺

采用0402标准贴片封装,符合IPC标准,兼容回流焊、波峰焊等常规贴片工艺,焊接后焊点可靠性高,长期使用无虚焊风险。厚膜工艺(丝网印刷+高温烧结)确保电阻层与陶瓷基底结合牢固,抗机械应力能力优于薄膜电阻。

3.2 环境适应性

  • 工作温度:-55℃至+155℃,覆盖工业级(-40℃+85℃)和汽车级(-55℃+125℃)部分场景,可满足户外设备、车载电子的低温启动和高温工作需求;
  • 环保合规:符合RoHS 2.0、REACH标准,无铅无卤,适配全球市场环保要求;
  • 可靠性测试:经过湿热循环(85℃/85%RH,1000小时)、温度循环(-55℃~+155℃,1000次)测试,阻值变化率控制在±0.5%以内,符合行业可靠性标准。

四、典型应用场景

FRL0402FR500TS因“小封装+低功耗+高精度”的组合优势,广泛应用于:

  1. 便携电子设备:智能手机、平板电脑的主板信号调理(如传感器前端分压、低功耗逻辑电路限流);
  2. 可穿戴设备:手环、蓝牙耳机的电池保护电路小电流采样(低功耗不影响设备续航);
  3. 小型工业控制:PLC模块的输入输出回路限流、小型传感器的信号放大前端电阻;
  4. 消费电子配件:充电器、移动电源的辅助电路(如指示灯限流、电压检测分压);
  5. 汽车电子(低功率场景):车载USB接口的过流保护辅助电阻(适配-40℃~+85℃车载环境)。

五、品牌与可靠性说明

富捷电子(FOJAN)是国内专注被动元件的制造商,拥有10余年生产经验,通过ISO9001认证。FRL0402FR500TS采用全自动生产设备,阻值分选精度达±0.5%,确保批次一致性。产品提供1年质保,支持批量定制(如阻值微调、包装规格调整),适合电子厂商量产需求。

该电阻以“高性价比+宽适应性”为核心竞争力,是小型化电子设备中替代传统电阻的优选方案。

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
