RALEC RTT021R00FTH 厚膜电阻产品概述

一、产品定位与核心特性

RALEC(旺诠)RTT021R00FTH是一款微型封装通用厚膜电阻,核心定位为平衡“小体积高密度布局”与“稳定性能”的入门级元件,适合工业控制、消费电子、汽车辅助电路等场景。其核心特性可总结为:

  • 0402超小封装适配紧凑PCB设计;
  • ±1%高精度满足信号匹配、电流采样需求;
  • 宽温范围(-55℃~+155℃)覆盖 harsh环境;
  • 低功耗(62.5mW)兼顾便携设备续航。

二、基础电气参数详解

该电阻的关键参数明确了性能边界,具体解读如下:

  • 阻值与精度:标称1Ω,精度±1%——25℃下实际阻值为0.99Ω~1.01Ω,可满足多数模拟电路的阻抗匹配(如音频模块)、低阻值电流采样(如传感器信号调理);
  • 额定功率:62.5mW(1/16W)——对应0402封装典型功率,额定功率下连续工作阻值变化可控制在精度范围内;
  • 额定电压:50V——指长期承受的最大电压(直流/交流通用),需注意:实际工作需以“功率不超62.5mW”为核心约束(如U=50V时P=2500W,远超额定,仅作为绝缘强度上限);
  • 温度系数(TCR):±200ppm/℃——温度每变1℃,阻值相对变±0.02‰。按工作温区(210℃温差)计算,总阻值变化约±0.042Ω(即±4.2%),满足非极端温漂需求。

三、封装与物理特性

采用0402表面贴装封装(英制:0.04″×0.02″,公制:1.0mm×0.5mm),优势显著:

  • 适配高密度PCB(如智能手机多层板、智能穿戴模块),提升单位面积集成度;
  • 兼容自动贴片机生产,效率高、一致性好;
  • 无铅环保设计(符合RoHS),满足全球市场要求;
  • 封装公差小(±0.1mm),保证贴装精度。

四、环境适应性表现

环境参数覆盖多数应用场景:

  • 宽温工作:-55℃~+155℃——支持北方户外设备、汽车发动机舱周边、工业烤箱控制电路;
  • 厚膜工艺抗应力:丝网印刷+高温烧结工艺,抗冲击、抗振动性能优于薄膜电阻,适合手持设备跌落、工业机器人关节电路;
  • 湿度耐受:符合IEC 60068-2-60标准,可在热带沿海高湿度环境长期稳定工作。

五、典型应用场景

结合参数与封装,核心应用包括:

  1. 消费电子:智能手机音频阻抗匹配、智能手表心率传感器电流采样;
  2. 工业控制:小型PLC输入输出接口电阻、传感器节点信号分压;
  3. 汽车辅助电路:车载中控背光控制、胎压监测模块低功耗信号电阻(需确认汽车级认证);
  4. 通信设备:5G小基站射频前端滤波、光纤收发器阻抗匹配;
  5. 医疗电子:家用血糖仪信号校准电阻。

六、品牌与可靠性优势

RALEC(旺诠)30余年被动元件经验,RTT021R00FTH可靠性突出:

  • 工艺一致性:厚膜工艺成熟,批量阻值偏差、温漂控制行业前列;
  • 认证齐全:通过ISO 9001、ISO/TS 16949(汽车级可选)、RoHS认证;
  • 长期稳定性:额定条件下1000小时工作,阻值变化<±0.5%,满足长期使用需求。

该电阻凭借“小体积+稳定性能”的平衡,成为众多紧凑电子设备的优选元件。

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
