RTT026982FTH 贴片厚膜电阻产品概述

一、产品基本定位

RTT026982FTH是RALEC(旺诠) 推出的一款高性能厚膜贴片电阻,采用0402小型化封装,针对阻值精度、功率密度及宽温稳定性需求设计,适用于消费电子、工业控制、汽车电子等多领域的信号调理、分压偏置、滤波等电路场景。产品以成本效益与可靠性平衡为核心,满足中高端电子设备的轻量化、高密度集成需求。

二、核心参数详细说明

RTT026982FTH的核心参数精准匹配常见电子电路需求,关键指标如下:

  • 电阻类型:厚膜贴片电阻(厚膜工艺通过丝网印刷+高温烧结形成电阻层,兼顾稳定性与成本优势);
  • 阻值与精度:69.8kΩ ±1%(1%精度可满足多数模拟电路对阻值准确性的要求,避免信号采集/放大偏差);
  • 额定功率:62.5mW(低功耗设计,适合便携设备、低功耗传感器电路);
  • 最大工作电压:50V(电压上限匹配信号电路与低压电源电路的安全使用范围,避免过压击穿);
  • 温度系数(TCR):±100ppm/℃(每变化1℃,阻值变化约万分之一,宽温下性能稳定);
  • 工作温度范围:-55℃~+155℃(覆盖工业级环境温度,可应对户外设备、工业现场等极端高低温场景);
  • 封装规格:0402(英制封装,对应公制1005,尺寸约1.0mm×0.5mm,适配高密度PCB设计)。

三、技术特性与优势

  1. 宽温稳定性突出:±100ppm/℃的温度系数结合-55℃~+155℃的工作范围,使产品在极端环境下阻值漂移极小,适合户外基站、工业PLC等场景;
  2. 小型化集成适配:0402封装体积小巧,可显著降低PCB板面积,助力设备轻量化(如智能手机、可穿戴设备);
  3. 成本效益平衡:厚膜工艺替代部分薄膜电阻,在保证1%精度与长期稳定性的前提下,降低批量采购成本;
  4. 安全边界清晰:额定功率62.5mW与最大电压50V的组合,明确电路设计的安全约束(实际使用需同时满足功率≤62.5mW、电压≤50V,避免过功率/过电压损坏);
  5. 抗干扰能力较强:厚膜电阻层的结构设计,对高频噪声的抑制效果优于部分薄膜电阻,适合射频辅助电路、通信设备滤波模块。

四、典型应用场景

RTT026982FTH的参数特性使其适配多领域电路:

  • 消费电子:智能手机/平板电脑的音频信号调理、电源分压电路(低功耗+小型化);
  • 工业控制:PLC的传感器接口电路、模拟量采集模块(宽温+稳定精度);
  • 汽车电子:车载信息娱乐系统的背光控制、低功耗胎压传感器电路(符合汽车级部分温度要求);
  • 通信设备:路由器/基站的射频滤波电路、电源管理模块(小型化+抗干扰);
  • 医疗电子:小型血糖监测仪的信号放大电路(可靠性+宽温)。

五、品牌与品质保障

RALEC(旺诠)是全球知名被动元件制造商,专注电阻、电容研发生产超过30年,RTT026982FTH具备以下品质优势:

  • 认证合规:通过ISO9001质量管理体系、ISO/TS16949汽车行业认证,符合RoHS、REACH环保标准;
  • 制程管控:从原料筛选到烧结、测试全流程自动化检测,阻值精度一致性控制在±0.5%以内(高于标称1%);
  • 可靠性测试:经过高温老化(155℃×1000小时)、温度循环(-55℃+155℃×500次)、振动测试(10G20G),满足电子设备长期使用需求;
  • 供货稳定:全球布局台湾、大陆生产基地,可支持批量订单与持续供货。

六、封装与可靠性设计

0402封装采用表面贴装技术(SMT),适配自动化生产线,提高生产效率;厚膜电阻的烧结工艺使电阻层与氧化铝陶瓷基底附着力强,具备以下可靠性特点:

  • 抗振动性能:可承受10G~20G的振动环境,适合车载、工业设备等振动场景;
  • 耐磨损性:厚膜层厚度(约10~20μm)较薄膜电阻大,不易因机械摩擦导致阻值变化;
  • 长期稳定性:在额定参数下使用,使用寿命可达10万小时以上,符合电子设备的寿命要求。

综上,RTT026982FTH是一款兼顾精度、稳定性与成本的厚膜贴片电阻,可满足多领域电子设备的高密度集成与宽温应用需求。

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
