FRL1206FR300TS 厚膜贴片电阻产品概述

FRL1206FR300TS是FOJAN(富捷)品牌推出的一款1206封装厚膜贴片电阻,针对对阻值精度、空间紧凑性及宽温适应性有需求的电路设计场景优化,核心参数聚焦低阻值、高精度与小功率,是消费电子、工业控制等领域的通用型元件。

一、产品基本属性与定位

该电阻属于厚膜贴片电阻范畴,采用陶瓷基片印刷电阻浆料+高温烧结工艺,兼具成本优势与性能稳定性;封装规格为1206(英制标识,对应公制3216,尺寸3.2mm×1.6mm),适配表面贴装技术(SMT)生产线,支持批量自动化生产;品牌为FOJAN(富捷),作为专业电子元器件制造商,产品覆盖从通用到定制化电阻的全系列,FRL1206FR300TS定位为中高精度低阻通用贴片电阻,满足多数电路对阻值精度(±1%)、功率(250mW)的常规需求。

二、核心电性能参数详解

2.1 阻值与精度

核心阻值为300mΩ(毫欧),属于低阻值范畴;精度等级为**±1%**,即实际阻值范围在297mΩ~303mΩ之间,该精度可满足电流采样、电压分压等对阻值一致性要求较高的场景,无需额外校准即可实现基础功能。

2.2 功率与电压

额定功率为250mW,实际使用需遵循降额原则(如环境温度高于25℃时需降低功率使用),保证长期可靠性;工作电压参数为500V,可覆盖多数低压至中压电路的电压范围,避免过压击穿风险。

2.3 温度特性

温度系数(TCR)为**±300ppm/℃,即温度每变化1℃,阻值变化率为±0.0003%;结合工作温度范围-55℃~+155℃**,在全温区范围内,阻值最大变化量约为±0.0189mΩ,对多数电路性能影响可忽略,保证宽温环境下的稳定性。

三、物理特性与封装设计

3.1 封装与尺寸

1206封装是贴片电阻的主流规格之一,尺寸小巧(典型值3.2mm×1.6mm×0.5mm),可有效节省PCB空间,适合便携式设备、小型模块等对空间敏感的设计;引脚采用银/镍/锡三层端电极,可焊性良好,适配回流焊、波峰焊等工艺,焊接可靠性高。

3.2 工艺与结构

采用厚膜工艺:以氧化铝陶瓷基片为载体,印刷钌系电阻浆料,经高温烧结形成电阻层,再覆盖玻璃釉保护层;该工艺优势在于:① 电阻层与基片结合牢固,抗振动、抗冲击性能佳;② 玻璃釉保护层隔绝环境湿度、灰尘,提升长期稳定性;③ 成本低于薄膜电阻,适合批量应用。

四、环境适应性与可靠性

4.1 宽温工作能力

工作温度范围覆盖**-55℃~+155℃**,可满足工业级设备(如户外控制器、车载辅助系统)的极端温度需求,避免低温下阻值漂移、高温下功率衰减等问题。

4.2 长期可靠性

出厂前经过阻值分选(保证精度一致性)、功率老化测试(筛选早期失效品)、温度循环测试(验证宽温可靠性);据FOJAN官方数据,额定条件下使用,阻值漂移率通常小于0.5%/1000小时,满足多数产品生命周期要求。

五、典型应用场景

5.1 电流采样电路

300mΩ低阻值适合小电流采样(如电池管理系统BMS中单体电池充放电电流检测,采样电压=电流×300mΩ,便于ADC采集);±1%精度保证采样误差可控,避免电流误判。

5.2 电压分压电路

在高精度分压场景(如电源输出电压监测、传感器信号调理),可与其他阻值电阻配合实现准确分压比,满足模拟电路精度要求。

5.3 小型功率电路限流

250mW额定功率可满足小功率电路限流需求(如LED驱动辅助限流、低压电源过流保护前端采样),避免元件过流损坏。

5.4 消费电子通用设计

1206封装小巧,适合智能手机、平板电脑等便携式设备PCB布局,可用于信号调节、滤波网络等基础电路。

六、品牌与质量保障

FOJAN(富捷)产品符合RoHS 2.0、REACH等环保标准,无铅无镉;FRL1206FR300TS出厂全参数测试,每批次提供合格证明,支持卷带编带、托盘等定制化包装;针对工业客户,可提供振动、湿热等额外可靠性验证报告,保障批量应用一致性。

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
