RTT05R560FTP 贴片厚膜电阻产品概述

RTT05R560FTP是RALEC旺诠推出的一款0805封装贴片厚膜电阻,针对低阻值、精密控制场景设计,具备工业级宽温适应性与稳定的电气性能,广泛适用于电流检测、电源管理等领域。

一、产品基本信息

该电阻属于旺诠RTT系列贴片厚膜电阻,采用厚膜丝网印刷工艺制造于陶瓷基板上,通过高温烧结形成稳定的电阻体。产品为表面贴装(SMD)设计,兼容主流SMT生产工艺(回流焊、波峰焊),可直接集成于高密度PCB电路板中,满足小型化电路的布局需求。

二、核心电气参数详解

RTT05R560FTP的核心参数精准匹配低阻值应用场景,关键指标如下:

  • 阻值与精度:标称阻值560mΩ(0.56Ω),精度±1%——相比常规±5%精度电阻,更适合需要精准电流采样、分压控制的电路;
  • 功率与电压限制:额定功率125mW,额定工作电压150V。实际使用需同时满足两个限制:① 工作功率≤125mW;② 工作电压≤150V。需注意:低阻值下满额功率对应的电流约为( I = \sqrt{P/R} \approx 14.9A ),实际选型需结合电路电流需求;
  • 温度系数(TCR):±200ppm/℃——表示温度每变化1℃,阻值变化±200×10⁻⁶,在宽温范围内阻值漂移可控;
  • 工作温度范围:-55℃~+155℃,覆盖工业现场、户外设备等极端环境,符合工业级可靠性要求。

三、封装与物理特性

  • 封装尺寸:0805(英制标准,对应公制尺寸2.0mm×1.25mm),体积小巧,可有效降低PCB布局空间,提升电路集成度;
  • 物理结构:以氧化铝陶瓷基板为载体,表面印刷厚膜电阻浆料,两端镀有可焊性电极(无铅合金),便于焊接且符合环保要求;
  • 重量:约0.01g(典型值),对轻量化设计的设备(如便携电子)友好。

四、性能优势

  1. 精密稳定:±1%阻值精度与±200ppm/℃温系,确保电路在不同温度、工况下的参数一致性;
  2. 宽温可靠:-55℃~+155℃工作范围,适应工业现场、户外设备等高低温环境;
  3. 小体积高集成:0805封装适配高密度PCB设计,满足消费电子、工业控制等领域的小型化需求;
  4. 工艺成熟:厚膜工艺成本可控,且具备良好的抗湿性、抗老化性,长期使用性能稳定;
  5. 品牌保障:RALEC旺诠是全球知名电阻制造商,产品通过ISO9001、AEC-Q200等认证,质量一致性可靠。

五、典型应用场景

RTT05R560FTP的低阻值、高精密特性,使其在多个领域发挥关键作用:

  1. 电流检测电路:电源管理模块(DC-DC转换器)、电池保护板、电机驱动电路中的电流采样——利用( V=I×R )将电流转换为电压信号,便于MCU检测;
  2. 精密分压电路:模拟电路中作为分压电阻,实现精准电压调节(如传感器信号调理);
  3. 小功率负载电阻:低电压小电流电路(如LED驱动、信号终端)中作为负载,稳定电路工作点;
  4. 工业控制设备:PLC、变频器等工业设备的信号调理电路,适应车间高低温、湿度变化;
  5. 消费电子:智能手机、笔记本电脑等便携设备的电源管理单元(PMU),满足小型化与精密控制需求。

六、可靠性与环境适应性

  • 温度循环测试:可承受-55℃~+155℃的温度循环(1000次以上),阻值变化率≤±0.5%;
  • 湿度稳定性:在85℃/85%RH环境下放置1000小时,阻值漂移≤±1%;
  • 机械性能:焊接后可承受振动(10~2000Hz,加速度2g)与冲击(1500g,1ms)测试,满足运输与现场使用要求;
  • 长期老化:在额定功率下工作1000小时,阻值变化≤±0.2%,性能稳定。

总结:RTT05R560FTP作为旺诠推出的精密低阻值厚膜电阻,以其宽温适应性、高精准度与小体积优势,成为电流检测、电源管理等领域的可靠选型,可满足工业级与消费电子的多样化需求。

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
