RTT024704FTH 厚膜贴片电阻产品概述

RTT024704FTH是RALEC旺诠推出的0402封装厚膜贴片电阻,针对小体积高密度PCB设计,兼顾高阻值、高精度与宽温适应性,广泛适配消费电子、工业控制、汽车电子等领域的小信号电路。

一、产品核心定位与基础属性

RTT024704FTH属于旺诠常规厚膜电阻系列,核心定位为小体积高阻值高精度辅助电阻,主要用于信号调理、偏置电路、电源监控等场景。基础属性清晰:

  • 采用厚膜工艺,平衡性能与成本;
  • 0402(英制)/1005(公制)封装,体积紧凑(1.0mm×0.5mm);
  • 标称阻值4.7MΩ(高阻值,满足弱信号偏置需求);
  • 精度±1%,覆盖大多数电子设备的常规精度要求。

二、关键电气性能参数详解

参数针对小信号电路优化,核心指标如下:

2.1 阻值与精度

  • 标称阻值:4.7MΩ(适合信号放大偏置、射频阻抗匹配);
  • 精度等级:±1%(厚膜工艺精准控制,阻值一致性良好,避免信号失真)。

2.2 功率与电压额定值

  • 额定功率:62.5mW(0402封装常规功率,满足小信号功耗);
  • 额定工作电压:50V(实际使用需同时满足P≤62.5mW和V≤50V,电压限制更严格——50V时功耗约0.53mW,远低于额定功率)。

2.3 温度系数(TCR)

  • 温度系数:±100ppm/℃(温度每变1℃,阻值变±0.01%);
  • 宽温适应性:-55℃~+155℃范围内,最大阻值变化约±2.1%,常温下(25℃±5℃)变化≤±0.1%。

三、物理封装与工艺特性

3.1 封装与焊接兼容性

  • 封装尺寸:1.0mm×0.5mm×0.3mm,符合IPC标准;
  • 焊接支持:回流焊(峰值260℃±5℃)、波峰焊,适配自动化贴片线。

3.2 厚膜工艺优势

  • 相比薄膜:成本更低,适合大规模量产;
  • 相比线绕:体积小、无电感效应(高频特性好);
  • 长期稳定性:1000小时125℃老化后,阻值漂移≤0.5%。

3.3 环保认证

符合RoHS 2.0标准(无铅、无镉等有害物质),部分批次通过IATF 16949汽车级认证。

四、典型应用场景

4.1 消费电子

  • 智能手机:摄像头传感器偏置、无线充电控制反馈电阻;
  • 智能穿戴:心率传感器信号调理电阻。

4.2 工业控制

  • PLC:输入输出分压、模拟量模块偏置电阻;
  • 小型传感器:温度/压力信号放大偏置。

4.3 汽车电子

  • 车载中控:触控校准、蓝牙射频阻抗匹配;
  • TPMS:传感器信号调理电阻(宽温适配车载环境)。

4.4 通信设备

  • 路由器:电源监控分压、以太网信号偏置;
  • 射频前端:LNA栅极偏置电阻。

五、可靠性与环境适应性

  • 温度耐受:-55℃~+155℃,承受高低温变化;
  • 抗湿性:通过IEC 60068-2-67湿热测试(40℃/93%RH,1000小时),阻值变化≤1%;
  • 机械可靠性:1mm弯折半径下100次弯折无失效,适合便携设备振动环境。

六、品牌与品质背书

RALEC旺诠是台湾老牌被动元件厂商(成立1986年),产品覆盖全球:

  • 认证:ISO 9001、IATF 16949、RoHS 2.0;
  • 品质:自动化生产+在线检测,阻值一致性≤±0.5%;
  • 供应:月产能数亿只,满足中小批量到大规模需求。

RTT024704FTH凭借小体积、高阻值、宽温稳定等特性,成为多领域小信号电路的优选厚膜电阻,适合平衡空间、精度与成本的电子设计。

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
