RALEC RTT06R010FTP 厚膜电流采样电阻产品概述

一、产品核心定位与应用场景

RALEC RTT06R010FTP是旺诠(RALEC)推出的中端精度厚膜分流器,核心定位为中小功率电路的精准电流采样——在控制成本的前提下,平衡了精度、功率与可靠性,避免超高精度电阻的冗余设计,适配多领域的电流检测需求。

典型应用覆盖:

  • 消费电子:手机/平板充电器、无线充的输出电流检测;
  • LED驱动:小功率灯带、台灯的电流限制与亮度调节;
  • 工业控制:小型PLC模拟量输入、传感器工作电流监测;
  • 便携式储能:电动玩具、户外充电宝的电池电流采样;
  • 微型逆变器:家用太阳能微型逆变器(500W以内)的输出电流检测。

二、关键参数与性能解析

该产品参数围绕“低阻精准采样”优化,核心性能解析如下:

  1. 阻值与精度:10mΩ(0.01Ω)低阻值+±1%精度——低阻值将串联压降控制在极小范围(如5A连续电流时压降仅0.05V),不干扰主电路;±1%精度无需额外校准,可满足大多数系统的电流控制要求(如充电器±2%的电流误差标准)。
  2. 功率与电流能力:额定功率250mW,对应连续工作电流约5A(由I=√(P/R)计算),峰值电流可短暂超此值(需结合电路降额),适配中小功率电源的检测需求。
  3. 工作温度范围:-55℃+155℃宽温设计,远超普通消费级电阻(070℃),可稳定工作于工业级环境(如户外充电桩、车载低温场景)。
  4. 封装与尺寸:1206(英制3216公制)贴片封装,体积仅3.2mm×1.6mm,适合高密度PCB布局,兼容自动化SMT生产。

三、封装与工艺优势

  1. 1206封装的适配性:无引脚设计减少焊接缺陷,回流焊兼容性好(峰值温度260℃以下稳定焊接);体积小,可在紧凑PCB上节省1/3空间,适配超薄充电器等小型化产品。
  2. 厚膜工艺的可靠性:旺诠成熟厚膜印刷工艺使膜层附着力强、阻值均匀性好,长期工作阻值漂移极小(典型值:1000小时额定负载下漂移≤±0.5%);相比绕线电阻体积更小,相比薄膜电阻成本更低,性价比突出。
  3. 低电感设计:分流器电感是高频采样误差的主要来源,RTT06R010FTP采用短路径封装,电感值≤1nH,可满足几十kHz以内的开关电源采样需求(如快充PWM频率)。

四、可靠性与环境适应性

  1. 宽温稳定性:-55℃低温下阻值漂移≤±0.3%,155℃高温下(额定功率降额至50%)漂移≤±0.8%,符合IEC 60068-2-1/2(高低温)标准。
  2. 耐环境性能:通过潮湿试验(40℃/93%RH下1000小时),阻值变化≤±1%;符合RoHS无铅要求,适配环保型产品。
  3. 功率降额原则:高温环境需降额(如125℃时降额至70%,155℃时降额至50%),旺诠提供官方降额曲线供设计参考,确保长期可靠性。

五、典型应用案例参考

以手机快充充电器(5V/2A) 为例:

  • 电阻串联在输出回路,2A电流时压降为20mV,输入至ADC模块;
  • 芯片通过20mV信号精准判断电流,触发过流保护(如2.4A以上保护);
  • 1206封装与其他贴片元件(电容、电感)紧密布局,无需额外空间;
  • 宽温范围适配充电器在极端环境(高温户外、低温室内)下稳定工作。

另一案例:小型LED台灯(12V/0.5A),通过该电阻采样电流,芯片调节PWM占空比实现亮度无极调节,同时避免过流损坏LED。

总结:RALEC RTT06R010FTP是“精准、可靠、成本可控”的中端电流采样电阻,适配多场景中小功率检测需求,是消费电子与工业控制领域的高性价比选择。

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.
