RTT029090FTH 厚膜贴片电阻产品概述

一、产品定位与核心属性

RTT029090FTH是台湾旺诠(RALEC)推出的0402封装厚膜贴片电阻,属于高精度低功率通用型电阻,核心针对小型化、宽温环境下的电路设计需求,兼顾成本与可靠性,适用于消费电子、工业控制、车载电子等多领域的中低功耗场景。其定制化阻值(909Ω)与1%精度,能精准匹配特定电路需求,无需额外并联/串联调整。

二、关键参数详解

该电阻的核心参数围绕“小型化、高精度、宽温适配”设计,具体如下:

  • 阻值与精度:909Ω ±1%,为非标准定制阻值,±1%精度满足信号调理、阻抗匹配等需精准阻值的场景(如蓝牙模块天线匹配);
  • 额定功率:62.5mW,是0402封装的典型额定功率,适配便携设备、传感器接口等低功耗电路;
  • 工作电压:50V(直流/交流峰值),需与功率参数共同约束使用(实际功耗需同时满足P≤62.5mW、V≤50V);
  • 温度系数:±100ppm/℃,表示温度每变化1℃,阻值变化±9.09μΩ,100℃温差下偏差约±0.9Ω,一般应用可忽略影响;
  • 工作温度范围:-55℃~+155℃,覆盖工业级、车载级宽温需求,能适应极端环境温度变化。

三、封装与工艺特点

  • 封装规格:0402(英制,对应公制1005),体积仅1.0mm×0.5mm×0.3mm,适配智能手机主板、可穿戴设备等高密度PCB布局;
  • 厚膜工艺:采用丝网印刷厚膜浆料+高温烧结工艺,膜层厚度远大于薄膜电阻,具有抗机械应力强、耐环境腐蚀好、成本适中等优势,批量生产稳定性高;
  • 品牌合规性:旺诠(RALEC)是全球知名电阻制造商,产品符合RoHS、REACH等环保标准,可靠性经行业认证。

四、典型应用场景

结合参数与工艺特点,该电阻主要适用于以下场景:

  1. 便携消费电子:智能手环、蓝牙耳机的信号放大电路、电源管理模块(小封装适配高密度设计,低功率匹配低功耗需求);
  2. 工业控制模块:温度传感器、压力传感器的信号调理电路(宽温范围适应车间、户外等环境);
  3. 车载电子:倒车雷达、仪表盘的辅助电路(-55℃~+155℃符合车载环境温度标准);
  4. 小型通信设备:蓝牙5.0、WiFi模块的天线阻抗匹配电路(±1%精度满足阻抗精准匹配,减少信号损耗)。

五、可靠性与使用注意事项

  • 宽温可靠性:厚膜工艺与宽温设计使其能在极端温度下稳定工作,无阻值漂移超标的问题;
  • 抗振动性能:厚膜膜层附着力强,可承受电子设备常见振动(如车载行驶振动);
  • 降额建议:实际应用建议按50%功率降额(最大实际功耗≤31.25mW),延长产品寿命;
  • 焊接要求:回流焊峰值温度需控制在260℃以内(符合旺诠工艺规范),避免焊接温度过高损坏电阻。

总结:RTT029090FTH是一款适配多场景的高性价比厚膜贴片电阻,以小体积、高精度、宽温适配为核心优势,能满足消费电子、工业、车载等领域的低功耗电路设计需求。

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
