RALEC旺诠RTA02-4D750JTH 4位SMD排阻产品概述

RALEC旺诠作为全球被动元器件领域的老牌制造商,其RTA02-4D750JTH系列4位表面贴装(SMD)排阻专为小型化、高密度电子电路设计,凭借紧凑封装、稳定电气性能及高性价比,广泛覆盖消费电子、智能穿戴、工业控制等场景。以下从核心参数、封装配置、电气特性、应用场景及品牌优势展开详细概述。

一、产品核心参数概览

RTA02-4D750JTH为4位独立电阻排,核心参数完全匹配中低端电子电路的常规设计需求,具体如下:

  • 电阻器数量:4个独立阻值元件(无公共端,设计更灵活)
  • 标准阻值:75Ω(型号后缀“750”表示75×10⁰Ω)
  • 精度等级:±5%(后缀“J”为行业通用精度编码)
  • 单个元件功率:62.5mW(额定功率,无降额时稳定工作)
  • 温度系数:±200ppm/℃(阻值随温度变化的稳定性指标)
  • 引脚数量:8脚(4个电阻各2个独立引脚,线性排列)
  • 封装规格:SMD 2×1mm(微型封装,适配高密度PCB)

需注意:排阻总功率为单个元件功率之和(4×62.5mW=250mW),设计时需避免单电阻过载。

二、封装与引脚配置

RTA02-4D750JTH采用2×1mm微型SMD封装,是当前消费电子领域主流的排阻封装之一,核心优势如下:

  1. 空间效率:相比4个独立0402封装电阻(单个1.6×0.8mm),可节省约70%PCB面积,适配智能手环、蓝牙耳机等超小型设备;
  2. 贴装兼容性:封装符合IPC-A-610标准,适配自动化贴片机(SMT),贴装精度高、故障率低,提升生产线效率;
  3. 引脚布局:8脚采用“双排4脚”对称设计,4个电阻线性排列,每个电阻两端引脚独立,可灵活实现上拉、下拉、分压等多种功能。

三、电气性能特点

RTA02-4D750JTH的电气性能兼顾稳定性与成本效益,适合对精度要求不苛刻但需小型化的场景:

  1. 阻值精度:±5%精度覆盖单片机IO口上拉、LED限流等常规需求,无需额外采用高精度电阻,降低BOM成本;
  2. 功率特性:62.5mW单个功率可满足低功耗电路(如3.3V电源下,75Ω电阻最大电流≈28.9mA,可驱动多个小电流负载);
  3. 温度稳定性:±200ppm/℃温度系数意味着在-55℃~125℃范围内,阻值最大变化为75Ω×100℃×200e-6=1.5Ω,远小于±5%精度范围(3.75Ω),确保环境温度变化时性能稳定;
  4. 可靠性:采用旺诠专利厚膜电阻工艺,阻值一致性好,耐冲击、耐老化符合MIL-STD-202标准,长期工作无漂移。

四、典型应用场景

RTA02-4D750JTH凭借紧凑封装与灵活引脚,广泛应用于以下场景:

  1. 智能穿戴:智能手环的加速度计、心率传感器IO口上拉电阻(4个传感器同时配置,节省PCB空间);
  2. 消费电子:蓝牙耳机按键电路下拉电阻、小夜灯4个LED串联限流电阻(替代4个独立电阻,简化SMT流程);
  3. 工业控制:小型PLC数字输入口上拉电阻、传感器信号分压网络(4个通道同时分压,减少元件数量);
  4. 汽车电子:车载USB接口静电防护分压电阻(满足-40℃~85℃汽车级工作温度)。

五、品牌与环保优势

RALEC旺诠作为台湾老牌厂商,其RTA02-4D750JTH具有显著的品牌与环保优势:

  1. 品质可靠:40余年电阻生产经验,产品通过ISO 9001/14001认证,符合RoHS、REACH指令,无铅无卤;
  2. 供应链稳定:全球布局生产基地,可满足大批量订单,交货周期短;
  3. 成本效益:相比进口品牌同规格排阻,价格更具竞争力,适配中低端设备成本控制。

综上,RALEC旺诠RTA02-4D750JTH是一款**“小型化、高性价比、稳定可靠”**的被动元器件,可满足多数电子电路的常规设计需求,是消费电子、智能穿戴等领域的优选方案。

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.
