RALEC RTA03-4D100JTP 排阻产品概述

RALEC(旺诠)RTA03-4D100JTP是一款专为高密度电路设计的小型化表面贴装排阻,集成4个10Ω独立电阻,具备体积小、一致性好、可靠性高的特点,广泛适配消费电子、工业控制等中小功率电路场景。

一、产品定位与核心属性

该排阻属于4位独立电阻集成封装,核心定位是替代4个离散0603电阻,通过集成设计实现两大价值:

  1. 空间节省:4个0603电阻集成于1206封装,占板面积仅为离散元件的1/4;
  2. 一致性提升:单排集成确保4个电阻的阻值偏差、温漂特性高度一致,优于离散元件拼接效果。

核心属性可概括为:10Ω×4独立电阻、±5%精度、62.5mW/单个功率、±200ppm/℃温度系数、8引脚1206封装。

二、电气性能参数详解

1. 阻值与精度

标称阻值为10Ω(型号中“100”对应10×10⁰Ω),精度等级为**±5%**(“J”为E24系列精度代码),满足大多数工业控制、消费电子的常规应用需求,无需额外校准。

2. 功率与散热

单个电阻额定功率62.5mW,4个电阻集成于1206封装后,整体散热面积优于4个离散0603电阻(0603封装面积仅为1206的1/4),实际使用中若4个电阻同时工作,总功率可稳定承载250mW左右,无需额外散热设计。

3. 温度特性

温度系数为**±200ppm/℃,即环境温度每变化1℃,阻值变化±0.02%。结合工作温区-55℃~125℃**计算,最大阻值漂移约±0.35Ω,可满足常规宽温环境下的性能稳定性。

三、机械封装与引脚配置

1. 封装尺寸

整体采用1206英制封装(对应公制3.2mm×1.6mm×0.5mm),内部集成4个0603(1.6mm×0.8mm)电阻单元,封装材料为陶瓷基片+环氧树脂,具备良好的抗冲击、抗振动性能,符合表面贴装工艺要求。

2. 引脚布局

采用8引脚双列表面贴装(SOIC-like布局),每个电阻对应2个独立引脚,无共接端设计,可灵活实现4个电阻的串联、并联或独立使用,适配不同电路拓扑结构(如分压、限流、匹配网络等)。

四、典型应用场景

因集成度高、一致性好,该排阻主要应用于以下场景:

  1. 消费电子:手机/平板按键电路的上拉/下拉电阻(4个按键共用同一排阻,节省PCB空间)、音频设备的耳机接口限流阵列;
  2. 工业控制:PLC输入模块的数字量限流电阻、传感器接口的多通道分压电阻(保证信号一致性);
  3. 通信设备:射频前端的低噪声放大器(LNA)匹配网络、电源模块的DC-DC反馈电阻阵列。

五、品牌与可靠性优势

RALEC(旺诠)是台湾老牌被动元件制造商,成立于1985年,产品覆盖电阻、电容等领域,具备三大优势:

  1. 认证齐全:通过ISO9001质量管理体系、IATF16949汽车行业认证、RoHS环保认证;
  2. 工艺成熟:自动化生产与检测,阻值一致性控制在±2%以内(优于标称±5%);
  3. 可靠性验证:经振动测试(10G2000Hz)、温度循环测试(-55℃125℃,1000次),长期使用阻值漂移率<0.5%/1000小时。

六、选型与使用注意事项

  1. 功率计算:单个电阻实际功耗需≤62.5mW(如电流10mA时,功耗为10Ω×(0.01A)²=1mW,远低于额定值);
  2. 焊接要求:采用回流焊工艺(温度曲线符合IPC-J-STD-020标准),手工焊接温度需≤350℃,避免损坏封装;
  3. 温区适配:若应用场景温度超过125℃,需选择旺诠高温型排阻(如RTA03-4D100JTP-H)。

综上,RALEC RTA03-4D100JTP排阻以高集成度、稳定性能与成本优势,成为中小功率电路中替代离散电阻的理想选择,广泛适配多领域的高密度设计需求。

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.
