RTT031803FTP 贴片厚膜电阻产品概述

RTT031803FTP是台湾旺诠(RALEC)推出的一款0603封装贴片厚膜电阻,针对小型化、高可靠性电子设计需求优化,具备精准阻值控制、宽温稳定及低成本特性,广泛适配消费电子、工业控制等多领域应用。

一、产品基本信息

该型号属于旺诠常规功率型厚膜电阻系列,核心定位为中精度、低功率贴片电阻,采用陶瓷基片厚膜工艺制造,符合RoHS环保标准,支持自动化表面贴装(SMT)生产,适合高密度PCB布局设计。

二、核心性能参数

RTT031803FTP的关键参数匹配主流电子设计需求,具体如下:

  1. 阻值与精度:标称阻值180kΩ,精度±1%——满足大部分信号调理、分压电路的精准度要求,避免因阻值偏差导致的电路性能波动;
  2. 额定功率:100mW(0.1W)——属于低功率贴片电阻,建议实际使用功率不超过额定值的80%(即80mW),以提升长期可靠性;
  3. 最大工作电压:75V——适用于常规直流/低频交流电路,避免电压过高导致电阻击穿;
  4. 温度系数(TCR):±100ppm/℃——温度每变化1℃,阻值变化约0.01%,在-55℃~+155℃宽温范围内,阻值稳定性符合工业级应用标准;
  5. 工作温度范围:-55℃~+155℃——覆盖常规工业环境(如户外设备、车载辅助电路)及极端温度场景,无需额外降额设计。

三、封装与工艺特点

  1. 封装规格:采用0603英制封装(对应公制1608),尺寸为长1.6mm×宽0.8mm×厚0.45mm(典型值),体积小巧,可大幅节省PCB空间,适配手持设备、小型模块等紧凑设计;
  2. 厚膜工艺优势:通过丝网印刷金属氧化物电阻浆料于氧化铝陶瓷基片,经高温烧结成型,兼具以下特点:
    • 成本低于薄膜电阻,适合量产;
    • 阻值稳定性优于碳膜电阻,长期使用阻值漂移小;
    • 耐脉冲能力较强,可承受短时间过功率冲击(需符合 datasheet 脉冲降额要求)。

四、主要应用领域

RTT031803FTP凭借小体积、宽温稳定及精准度,广泛应用于以下场景:

  1. 消费电子:智能手机、平板电脑、智能穿戴设备的电源分压、信号滤波电路;
  2. 工业控制:PLC(可编程逻辑控制器)、传感器接口电路、小型电机驱动模块;
  3. 汽车电子:车载中控、倒车雷达辅助电路(常温段应用,若需高温段需确认AEC-Q200认证);
  4. 通信设备:路由器、小型基站的信号调理、偏置电路;
  5. 医疗设备:便携式监护仪、血糖仪的低功率分压、限流电路。

五、品牌与可靠性说明

旺诠(RALEC)作为全球知名电阻制造商,RTT031803FTP具备以下可靠性保障:

  1. 生产工艺符合ISO9001质量管理体系,阻值一致性好,批量生产偏差控制严格;
  2. 产品通过RoHS、REACH环保认证,无铅无卤,符合全球电子行业环保要求;
  3. 长期可靠性测试显示,在额定参数下工作1000小时,阻值漂移小于0.5%,满足工业级产品寿命需求。

六、选型与使用注意事项

  1. 功率降额:实际使用功率建议≤80%额定功率(80mW),避免长期过功率导致阻值漂移或失效;
  2. 电压限制:工作电压不得超过75V(直流或峰值电压),防止电阻击穿;
  3. 贴装要求:0603封装需采用自动化贴片机,贴装精度需控制在±0.1mm以内,避免虚焊;
  4. 温度适配:若应用场景温度超出-55℃~+155℃,需重新评估选型,选择更高温规格电阻。

该型号平衡了性能、成本与体积,是小型化电子设计中中精度低功率电阻的优选方案。

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
