PSA FBF06FTPR100 采样电阻产品概述

一、产品定位与核心价值

PSA信昌电陶推出的FBF06FTPR100是一款针对中小功率电路设计的贴片式低阻值电流采样电阻,核心定位是兼顾「精度、功率、体积平衡」,适配工业控制、消费电子等领域的紧凑化电流检测需求——既满足基本的过流保护、状态监测功能,又避免过高精度带来的成本冗余。

二、关键性能参数深度解析

1. 低阻值与采样适配性

阻值100mΩ(0.1Ω)属于电流采样的典型低阻范围:

  • 压降可控:2A电流下仅产生0.2V压降,不影响电池、电源等对能量效率敏感的电路;
  • 检测易实现:mV级压降适配普通运放即可精准采集,无需特殊高灵敏度器件。

2. 精度与温度稳定性

  • 精度±1%:覆盖中低端工业、消费类应用的核心需求(如电池SOC计算、电源过流保护),无需0.1%级高精度带来的成本提升;
  • 温度系数±100ppm/℃:温度每变化1℃,阻值漂移±0.01%;在-55℃~125℃宽温范围内,60℃温差下漂移仅±0.6%,保证不同环境下的检测一致性。

3. 功率与负载能力

额定功率750mW(25℃环境),结合100mΩ阻值,可支持最大连续电流约2.74A(公式:(I=\sqrt{P/R}=\sqrt{0.75/0.1}\approx2.74A)),适配10W以内电源模块、小功率电机等中小负载场景。

4. 封装与安装

采用1206贴片封装(公制3216,尺寸3.2mm×1.6mm):

  • 体积紧凑:适配手机充电器、小型BMS等小型化PCB;
  • 自动化友好:支持回流焊、波峰焊,无手工焊接依赖。

三、可靠性与工艺设计

PSA采用厚膜电阻工艺制造该产品,核心可靠性设计包括:

  • 焊接耐受:峰值焊接温度≤260℃时无性能衰减,适配常规SMT产线;
  • 环境抗性:抗湿、抗盐雾符合工业级标准,可用于户外充电桩、家电等场景;
  • 长期稳定:老化测试后阻值漂移≤0.5%,5年使用周期内精度保持性良好。

四、典型应用场景

1. 电池管理系统(BMS)

  • 单体/模组充放电电流采样:低阻压降不影响电池性能,精度满足SOC计算;
  • 过充/过放保护:电流检测触发保护电路,防止电池鼓包、损坏。

2. 开关电源模块

  • 输出电流监测:实时反馈电流,实现恒流控制或过流保护;
  • 效率优化:精准检测损耗电流,辅助拓扑结构优化。

3. 小功率电机驱动

  • 直流/步进电机电流检测:防止过载,延长电机寿命;
  • 伺服控制:辅助电流环调节,提升电机定位精度。

4. 消费电子

  • 充电器/移动电源:电流检测实现快充适配、过流保护;
  • LED驱动电源:恒流控制采样,保证LED亮度稳定。

五、选型与使用注意事项

1. 功率降额

环境温度超25℃需降额:

  • 85℃时额定功率降至375mW,最大电流≤1.93A;
  • 105℃时额定功率降至225mW,最大电流≤1.5A。

2. 焊接工艺

  • 回流焊:峰值温度≤260℃,时间≤10秒;
  • 波峰焊:温度≤240℃,时间≤5秒;
  • 避免手工焊接局部过热,防止电阻开裂。

3. 电路设计细节

  • 采样运放选低失调型(≤10μV),避免运放误差干扰;
  • 电阻靠近电流路径,减少线路阻抗干扰。

4. 环境适配

确认应用温度在-55℃~125℃内,超出需加散热片或更换高温规格产品。

FBF06FTPR100凭借「低阻、精准、紧凑」的特性,成为中小功率电流检测场景的高性价比选择,覆盖从消费电子到工业控制的多领域需求。

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
