RALEC RTA03-4D1002FTP 4位表面贴装排阻产品概述

一、产品核心定位

RALEC RTA03-4D1002FTP是台湾旺诠(RALEC)推出的4位集成式表面贴装排阻,专为需要紧凑集成多个高精度电阻的电路设计。产品整合4个10kΩ、1%精度的小功率电阻于1206封装内,既满足电路对电阻网络的需求,又大幅节省PCB空间与贴装成本,适用于中高精度要求的电子系统。

二、关键参数详解

该排阻的核心参数直接决定其应用场景,具体如下:

  1. 电阻特性:共4个独立电阻,每个阻值为10kΩ,精度等级为±1%(实际阻值范围9.9kΩ~10.1kΩ),满足多数中精度电路的阻值一致性需求;
  2. 功率规格:单个电阻额定功率为62.5mW,连续工作时需确保实际功耗不超过此值(4个电阻同时满功率工作总功耗约250mW);
  3. 温度稳定性:温度系数(TCR)为**±200ppm/℃**,即环境温度每变化1℃,单个电阻阻值变化±2Ω(10kΩ×200×10⁻⁶),适合常规环境温度波动(-40℃~85℃)下的稳定工作;
  4. 封装与引脚:整体封装为1206(英制尺寸,对应公制3216),每个集成电阻的封装为0603,引脚数为8,符合常规排阻的「公共端+4电阻端」配置。

三、封装与引脚配置说明

  1. 封装集成优势:将4个0603封装电阻整合至1206封装,相比单独贴装4个0603电阻,可减少75%的贴装点数,同时节省约50%的PCB占用面积,显著降低生产效率与成本;
  2. 引脚功能:8引脚排阻采用行业常规布局(需以官方datasheet为准),通常1脚为公共端,2-5脚为4个电阻的输出端,6-8脚为冗余或接地端,便于电路中多个电阻共享公共节点(如上拉/下拉网络、分压电路)。

四、性能优势与可靠性

  1. 集成度高,成本优化:集成设计减少PCB布线复杂度与物料管理成本,适合批量生产场景;
  2. 精度稳定,一致性好:±1%精度与±200ppm/℃温漂,确保电路在不同温度下的阻值偏差可控,满足信号调理、分压等需求;
  3. 品牌可靠性保障:旺诠作为专业电阻制造商,产品符合RoHS无铅标准,耐焊接温度(≥260℃)与环境可靠性(湿度、振动等)符合行业标准,适合工业、消费电子等多领域;
  4. 小功率适配性:62.5mW单个功率适配低功耗电路,如微控制器I/O口上拉、传感器信号分压等场景。

五、典型应用领域

RALEC RTA03-4D1002FTP因紧凑集成与稳定性能,广泛应用于以下场景:

  1. 消费电子:智能手机、平板电脑的按键电路(上拉电阻网络)、音频接口信号调理;
  2. 工业控制:PLC输入输出模块、传感器信号放大电路的分压网络;
  3. 通信设备:路由器、交换机的射频前端匹配网络、电源监控电路的电阻检测;
  4. 汽车电子:车载辅助电路(如仪表盘背光调节、传感器信号滤波)的低功耗电阻网络(需确认汽车级认证后适用)。

该产品是中低功耗、中高精度电阻网络的高性价比选择,适合追求紧凑设计与成本优化的电子系统。

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
