RALEC RTA02-4D151JTH 4位贴片排阻产品概述

一、产品基本定位与核心特征

RALEC(旺诠)RTA02-4D151JTH是一款专为高密度电路设计的4位集成贴片排阻,采用小型化SMD封装,将4个独立150Ω电阻整合为单一组件,核心定位是替代离散电阻以简化布线、节省空间,适用于消费电子、工业控制、通信等领域的紧凑电路布局。其核心特征包括:高集成度、阻值一致性优、焊接兼容性强、环境适应性稳定。

二、核心参数全解析

该排阻的关键参数需结合电阻网络设计逻辑逐一明确,避免参数误解:

  1. 阵列规格:包含4个独立电阻元件,引脚总数8个(含1个公共端引脚),支持“公共端+4路电阻输出”的典型应用;
  2. 阻值与精度:单个电阻阻值为150Ω(标识代码“151”,即15×10¹Ω),精度等级为±5%(标识代码“J”,符合E24系列电阻精度标准);同一排阻内各电阻的阻值一致性优于离散元件(典型偏差≤2%);
  3. 功率与温度特性:单个电阻额定功率为62.5mW,可稳定承载小功率信号电路(如5V电压下最大电流12.5mA);温度系数为±200ppm/℃,即温度每变化1℃,阻值变化范围为±200×10⁻⁶,能满足-40℃~85℃环境下的阻值稳定性;
  4. 封装尺寸:采用2.0mm×1.0mm的SMD贴片封装(对应“0402x4”标识,即4个0402尺寸电阻集成),厚度约0.5mm,适配高密度PCB设计。

三、封装与引脚配置

该排阻采用标准贴片封装,尺寸符合国际电子封装标准(IPC),支持回流焊、波峰焊等自动化贴装工艺,焊接缺陷率低于离散电阻(典型值≤0.1%)。引脚排列采用“单侧公共端+4侧电阻端”的8引脚设计:

  • 公共端引脚(通常为第1、5脚)可简化多路电阻的布线(无需单独连接每个电阻的一端);
  • 4个电阻端分别对应独立电阻的输出,可同时配置为分压、限流、上拉/下拉等功能。

四、品牌与可靠性保障

RALEC(旺诠)作为全球被动元件头部厂商,拥有30+年电阻研发生产经验,产品通过UL、VDE、RoHS、REACH等国际认证。RTA02-4D151JTH采用成熟厚膜电阻工艺,阻值稳定性高(长期使用漂移≤0.5%/1000小时),能满足工业级应用的可靠性要求(如振动、湿度环境下的性能不变)。

五、典型应用场景

  1. 消费电子:手机、平板、智能穿戴的接口电路(如USB Type-C上拉/下拉电阻网络、音频接口滤波电阻),利用小型化优势适配设备内部紧凑布局;
  2. 工业控制:小型PLC、传感器信号调理电路的电阻阵列,4个电阻可同时作为多路信号的分压元件,简化电路设计;
  3. 通信设备:路由器、小型基站的射频前端匹配电路,利用阻值一致性优的特点保证多路信号的均衡性;
  4. 汽车电子辅助电路:车载显示屏、音响的小功率控制电路,满足车内-40℃~85℃环境下的稳定工作。

六、性能优势总结

  1. 空间效率提升:4个0402电阻集成在2×1mm封装内,相比离散电阻节省约35% PCB面积;
  2. 阻值一致性优:同一排阻内电阻偏差远小于离散元件,减少多路信号偏差,提升系统性能;
  3. 生产效率优化:集成设计减少元件数量(从4个→1个),降低采购成本与贴装次数,适合自动化流水线;
  4. 可靠性增强:贴片封装焊接可靠性高,厚膜工艺稳定,长期使用故障率低。

该产品以“小型化+高集成+高可靠”为核心优势,是紧凑电路设计中替代离散电阻的理想选择,广泛适配中低端电子设备的量产需求。

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
