FRL0402JR500TS 厚膜贴片电阻产品概述

一、产品基本属性

FRL0402JR500TS是富捷(FOJAN)品牌推出的厚膜贴片电阻,采用行业通用的0402封装(英制尺寸,对应公制1005规格:长1.0mm×宽0.5mm),属于小型化高密度电路的基础无源元件。型号命名遵循行业逻辑:前缀“FRL”为富捷厚膜电阻系列代号,“0402”明确封装规格,“J”代表精度等级(±5%),“R500”表示标称阻值500mΩ(毫欧),后缀“TS”对应标准编带包装(适配自动化贴装)。

二、核心性能参数

该电阻的关键参数匹配厚膜贴片电阻的典型设计,具体如下:

  1. 阻值与精度:标称阻值500mΩ,精度±5%(J级),满足常规电路对电阻值的基础控制需求;
  2. 功率额定值:额定功率62.5mW(0.0625W),符合0402封装小功率应用的设计边界;
  3. 工作电压:额定工作电压100V,支撑常规低压电路的电压耐受要求;
  4. 温度特性:温度系数(TCR)±300ppm/℃,即在-55℃~+155℃范围内,阻值随温度变化的漂移率≤0.3%/℃;
  5. 环境适应性:工作温度覆盖-55℃至+155℃,符合工业级电子设备的环境耐受标准。

三、适用应用场景

因0402封装的小型化特性及500mΩ毫欧级阻值的分流/采样功能,该产品主要适用于:

  1. 消费电子终端:智能手机、智能手环的电池充放电电流采样、传感器供电线路限流;
  2. 小型电源模块:DC-DC转换器的输出电流检测、线性稳压器的负载电流监控;
  3. IoT与智能家居:智能插座、温湿度传感器节点的信号调理、低功耗通信模块的电流限制;
  4. 小型家电控制板:电动牙刷、加湿器的电机驱动电流检测、控制芯片偏置电阻。

四、工艺与可靠性特点

  1. 厚膜工艺优势:采用丝网印刷+高温烧结工艺,将电阻浆料印刷在氧化铝陶瓷基板上,形成致密电阻膜,兼具成本优势与性能稳定性;
  2. 封装可靠性:陶瓷基板+金属电极结构,耐温性优异,可承受回流焊/波峰焊高温,长期使用无开裂风险;
  3. 焊接兼容性:电极符合IPC-A-610标准,适配自动化贴装,回流焊峰值温度230℃~250℃下焊接良率≥99%;
  4. 长期稳定性:常规环境(25℃、湿度60%)下1000小时老化后,阻值漂移≤0.5%,满足设备长期可靠性要求。

五、选型与使用注意事项

  1. 功率降额:实际功率需控制在额定值的80%以内(≤50mW),125℃以上环境需降额至50%(≤31.25mW);
  2. 焊接工艺:回流焊遵循“预热→升温→峰值→冷却”曲线,峰值温度≤255℃、时间≤10秒;波峰焊浸锡深度≤0.2mm、温度240℃~250℃;
  3. 存储条件:未开封产品存储于-10℃~+40℃、湿度≤60%环境,开封后12个月内使用完毕,避免电极氧化;
  4. 应用匹配:电流采样时需确保线路寄生电阻≤0.1mΩ,若需更高精度(±1%),可选择富捷同系列高精度型号。

该产品以小型化、低成本、稳定可靠的特点,成为消费电子、IoT等领域小功率电流检测/分流应用的优选元件。

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
