RALEC旺诠RTT021302FTH厚膜贴片电阻产品概述

一、产品基本定位与规格概览

RALEC旺诠推出的RTT021302FTH是一款专为高密度、小功率电子电路设计的0402封装厚膜贴片电阻。该型号属于旺诠常规厚膜电阻系列,聚焦「1%精度+宽温范围」的核心需求,适配消费电子、工业控制、汽车电子等多领域的小型化电路应用。其核心规格明确:固定阻值13kΩ,额定功率62.5mW,工作温度覆盖-55℃至+155℃,符合主流电子设备的环境适应性要求。

二、核心性能参数详解

1. 阻值与精度

固定阻值13kΩ,精度等级±1%——该精度在厚膜电阻中属于较高水平,可满足多数电路的阻抗匹配、分压/限流等功能需求(如模拟电路偏置网络、数字电路上拉/下拉),避免因阻值误差导致的信号偏移。

2. 功率与电压约束

额定功率62.5mW,额定工作电压50V。实际使用需同时满足两个限制:

  • 功率限制:实际功率≤62.5mW(如电压28V时,功率≈28²/13000≈61mW,符合要求);
  • 电压限制:实际电压≤50V(若电压接近50V,功率≈192mW,远超额定值,需严格按功率优先原则使用)。

3. 温度系数与漂移

温度系数±100ppm/℃——表示温度每变化1℃,阻值变化±1.3Ω(13kΩ×100×10⁻⁶)。结合-55℃~+155℃的温差(210℃),总阻值变化约±273Ω(相对于13kΩ为±2.1%),叠加初始±1%精度,整体误差范围≤±3.1%,覆盖多数场景的温度漂移需求。

4. 封装与尺寸

0402英制封装(1.0mm×0.5mm),是当前贴片电阻中体积最小的规格之一,适合高密度PCB布局(如可穿戴设备、小型传感器模块),有效降低电路空间占用。

三、设计与工艺优势

1. 厚膜工艺可靠性

采用丝网印刷厚膜电阻浆料+高温烧结工艺,电阻膜层附着力强、稳定性高,长期使用阻值漂移小,适合批量生产的一致性要求。

2. 小体积高密度集成

0402封装的超小尺寸,可在单位PCB面积内集成更多元件,提升电路集成度,适配智能手机、智能手表等小型化终端。

3. 宽温环境适应性

-55℃~+155℃的工作温度范围,覆盖汽车电子(发动机舱环境)、工业控制(户外设备)等恶劣环境的温度需求,无需额外增加温度补偿电路。

4. 成本与性能平衡

厚膜工艺相比薄膜电阻成本更低,同时满足1%精度与宽温需求,是多数中端电子设备的性价比之选。

四、典型应用场景

1. 消费电子终端

  • 智能手机/平板电脑:传感器电路(加速度计、陀螺仪偏置电阻)、音频模块信号分压电阻;
  • 可穿戴设备:智能手环/手表的低功耗限流电阻。

2. 工业控制模块

  • 小型PLC:输入/输出接口电阻、传感器信号调理电路(如温度传感器分压网络)。

3. 汽车电子组件

  • 车载TPMS(胎压监测):信号处理电阻;
  • 车载小型传感器:车内温度传感器反馈电阻(宽温适配汽车高低温环境)。

4. 通信设备辅助电路

  • 小型基站/路由器:射频前端偏置电阻、电源模块限流电阻(0402封装适配高密度PCB)。

五、品牌与品质保障

RALEC旺诠是全球知名被动元件制造商,专注贴片电阻研发生产超30年。RTT021302FTH系列符合RoHS 2.0、REACH等环保标准,通过高温存储、温度循环、湿度测试等可靠性验证,批量一致性好,可满足电子设备长期稳定运行需求。

该产品以「小体积、高精度、宽温适配」为核心优势,是电子设备小型化设计的实用选择。

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
