RALEC RTT011403FTH 厚膜贴片电阻产品概述

一、产品基本属性

RALEC(旺诠)是国内专业被动元器件制造商,RTT011403FTH 为其推出的厚膜贴片电阻型号,核心属性如下:

  • 电阻类型:厚膜贴片电阻(通过陶瓷基板印刷厚膜浆料烧结而成);
  • 封装规格:0201英寸(对应公制尺寸 0.5mm×0.25mm),属于小尺寸贴片范畴;
  • 品牌归属:RALEC(旺诠),国内被动元器件领域的主流供应商之一。

二、核心电气参数及意义

该电阻的关键电气参数覆盖常规电路设计的核心需求,具体如下:

1. 阻值与精度

  • 标称阻值:140kΩ(中等阻值范围,适配分压、滤波、信号衰减等场景);
  • 精度等级:±1%(实际阻值范围为 138.6kΩ~141.4kΩ),偏差较小,可满足传感器信号调理、简单分压电路等对阻值准确性有基础要求的场景。

2. 功率与电压

  • 额定功率:50mW(低功率设计,需注意实际应用需降额,建议≤30mW);
  • 额定工作电压:25V(过压易导致击穿,实际建议≤20V,降额80%提升可靠性)。

3. 温度特性

  • 温度系数(TCR):±200ppm/℃(环境温度每变化1℃,阻值变化率为±200×10⁻⁶;以140kΩ为例,10℃温差下阻值变化约±280Ω);
  • 工作温度范围:-55℃~+125℃(覆盖工业级< -40℃85℃ >和部分汽车级< -40℃125℃ >环境,可靠性强)。

三、封装与物理特性

0201封装是当前贴片电阻中尺寸最小的主流规格之一,具备以下特点:

  • 空间效率:适配高密度PCB布局(如智能手机主板、智能穿戴设备),可有效压缩电路板体积;
  • 工艺优势:厚膜工艺相比薄膜电阻成本更低,且耐湿、耐温性能优异,适合批量生产;
  • 焊接要求:需采用自动化贴装设备(如SMT贴片机),手工焊接难度高(易虚焊),需配套高精度焊接工艺。

四、典型应用场景

结合参数特性,该电阻主要适用于以下场景:

1. 便携式电子设备

  • 智能手机、智能手环、蓝牙耳机的信号调理电路(小空间需求+宽温稳定);
  • 小型可穿戴设备的电源滤波/分压电路(低功率+小封装)。

2. 工业控制模块

  • 传感器信号采集电路(如温度传感器、压力传感器的信号放大前级);
  • PLC输入输出模块的辅助分压电路(宽温环境适配)。

3. 消费类电子

  • 小型家电(电饭煲、加湿器)的控制板电路(成本敏感+常规精度需求);
  • 电视遥控器、智能音箱的信号衰减电路(低功率+小封装)。

4. 通信辅助电路

  • 小型基站、路由器的射频前端滤波电路(低功率+宽温稳定);
  • 无线模块的信号分压电路(小空间+常规精度)。

五、产品优势与适用限制

1. 核心优势

  • 小型化适配:0201封装满足电子设备轻薄化趋势,支持高密度布局;
  • 宽温可靠:-55℃~125℃覆盖极端环境,无需额外降额;
  • 成本可控:厚膜工艺降低制造成本,适合大规模量产;
  • 精度适配:±1%精度覆盖90%以上常规电路需求,无需复杂校准。

2. 适用限制

  • 功率上限:仅50mW,无法用于大电流(如电源输出滤波)或高功率场景;
  • 温度系数:±200ppm/℃不适合超精密温度敏感电路(如高精度仪表校准);
  • 焊接门槛:手工焊接难度高,需依赖自动化设备。

六、选型与使用建议

  1. 降额使用:实际工作功率≤30mW(降额70%),工作电压≤20V(降额80%),可延长使用寿命;
  2. 环境适配:若应用于汽车级(-40℃125℃)或工业级(-40℃85℃),该电阻完全覆盖;
  3. 精度补充:若需更高精度(如±0.1%),需选择薄膜电阻;若需更低温度系数(如±50ppm/℃),需更换对应规格。

综上,RALEC RTT011403FTH是一款小尺寸、宽温稳定、成本适中的厚膜贴片电阻,适合大多数常规电子设备的低功率、中等精度电路设计,是便携式电子、工业控制等领域的实用选型。

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.
