FBF25FPPR200 电流采样电阻产品概述

FBF25FPPR200是信昌电陶(PSA) 推出的一款贴片式电流采样电阻,专为大电流回路的精准电流检测设计,兼具低阻值、高功率密度与温度稳定性,适配多种工业及消费电子场景的需求。

一、产品核心定位与技术方向

该产品属于分流器类采样电阻,通过“电流→压降”的线性转换实现电流检测,核心解决“大电流下低损耗、宽温下高精度”的采样需求,是电源、新能源、工业控制等领域的常规选型元件。

二、关键技术参数详解

FBF25FPPR200的核心参数围绕“采样精度、功率承载、环境适应性”设计,具体如下:

2.1 阻值与精度

  • 阻值:200mΩ(毫欧级低阻值):远低于常规电阻,保证大电流通过时压降小(减少额外功率损耗),同时避免对电路信号的干扰;
  • 精度:±1%:满足工业级采样的典型精度要求,兼顾成本与性能,无需额外校准即可实现基础电流检测;

2.2 功率与电压承载

  • 额定功率:2W:2512封装下的高功率密度(常规同封装电阻功率多为1W以内),支持持续大电流工作(按功率计算:额定电流≈100A,压降≈20mV);
  • 工作电压:954mV(用户标注):需注意该参数为特定工况下的压降(或实际应用中的最大允许压降),需结合电路电流与阻值匹配使用;

2.3 温度系数

  • 温度系数:±100ppm/℃:表示温度每变化1℃,阻值变化±100×10^-6 Ω,在-55℃~125℃的宽温范围内(工业级标准),阻值变化极小,确保采样精度稳定;

三、封装与安装特性

FBF25FPPR200采用2512贴片封装(英制尺寸:6.4mm×3.2mm,公制约6.35mm×3.18mm),具备以下安装优势:

  1. SMT兼容:适配常规回流焊、波峰焊工艺,无需额外插件工序,适合自动化生产;
  2. 小型化设计:封装尺寸紧凑,可集成到小型化电源、BMS等设备中,节省PCB空间;
  3. 抗干扰性:贴片封装减少引线电感,降低高频信号干扰,提升采样准确性;

四、性能优势与可靠性

信昌电陶依托陶瓷基电阻技术,赋予FBF25FPPR200以下核心优势:

  1. 线性度优异:阻值与电流呈严格线性关系,无饱和效应,采样结果可直接通过欧姆定律换算;
  2. 抗恶劣环境:陶瓷基底具备抗冲击、抗振动性能,可承受10G以上振动(常规测试标准),适合工业现场、车载等 harsh环境;
  3. 长期稳定性:经过高温老化、湿度循环等可靠性测试,阻值漂移率低于0.5%/1000小时,满足设备长期运行需求;

五、典型应用领域

FBF25FPPR200的参数特性使其适配多场景电流采样,主要包括:

  • 新能源领域:电动车BMS(电池管理系统)的充放电电流检测、充电桩的输出电流监控;
  • 工业电源:UPS电源、开关电源的输出电流反馈、服务器电源的负载电流检测;
  • 工业控制:电机驱动器、变频器的电流闭环控制、PLC(可编程逻辑控制器)的模拟量输入采样;
  • 消费电子:大功率快充充电器(如65W/100W)的电流保护采样、户外电源的电池电流监控;

综上,FBF25FPPR200是一款性价比高、性能稳定的贴片电流采样电阻,覆盖工业级与消费电子的主流需求,是电流检测回路的可靠选型。

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
