4D03WGJ0101T5E 产品概述

一、产品简介

4D03WGJ0101T5E 是 UNI-ROYAL(厚声)品牌的一款表面贴装型四位排阻网络(resistor array),封装形式为 0603x4,器件共有 8 个引脚,内部包含 4 个阻值为 100Ω 的独立电阻单元。每个单元额定功率为 62.5mW,阻值公差为 ±5%,温度系数为 ±200ppm/℃。此类小型集成排阻常用于节省 PCB 面积、提高装配一致性与可靠性的低功耗信号与偏置网络场景。

二、主要电气参数

  • 电阻数量:4(四个独立电阻单元)
  • 标称阻值:100Ω(每单元)
  • 阻值精度:±5%
  • 单个元件额定功率:62.5 mW
  • 温度系数(TCR):±200 ppm/℃(约 ±0.02%/℃,即约 ±0.02Ω/℃ 对 100Ω)
  • 引脚数:8
  • 封装:0603x4(四并排 0603 大小电阻阵列)

补充实用计算:

  • 单元最大持续电流(理想情况下):I_max = sqrt(P/R) = sqrt(0.0625 / 100) = 0.025 A = 25 mA
  • 单元最大两端电压(理想情况下):V_max = I_max × R = 2.5 V

注意:上述最大值为理想静态计算值,实际可用电流/电压需参考生产厂家的温度上升与功率降额曲线以及整板热设计。

三、封装与引脚说明

  • 封装形式为 0603x4,外观紧凑,适合高密度 PCB 布局与自动化贴装。
  • 8 引脚排列通常用于四个独立电阻的两端连接(每个电阻占两引脚)。具体焊盘尺寸、引脚编号与内部连接方式请以厂方数据手册(Datasheet)标注为准。
  • 该类表面贴装排阻便于在一处完成多个偏置/上拉/下拉或阻抗分配,减少焊点数量并提升装配一致性。

四、特性与适用场景

  • 小体积、高集成:比四个分立 0603 电阻占用更少 PCB 面积,适合空间受限的便携设备、移动终端、消费类电子。
  • 一致性好:同一片基体上的四个电阻在材料和工艺上更一致,适合需要匹配与阵列特性的信号路由或 LED 驱动上拉/限流场合(注意功率限制)。
  • 信号与偏置网络:适用于逻辑上拉/下拉、分压网络、参考电阻、阻抗分配或输入终端的限流保护(在电压、电流限制范围内)。
  • 工业与消费:在温度变化不剧烈且功率需求较低的应用环境中表现优良,如传感器接口、数据总线末端阻抗、可编程电路的固定偏置等。

五、使用建议与注意事项

  1. 功率与热管理:62.5 mW 为单元额定功率,实际电路中应考虑 PCB 温升、周围器件热源及环境温度对功率能力的影响。建议在高温或密集器件区做降额使用,并参考厂方的功率降额曲线。
  2. 电压与电流限制:理论最大连续电流约 25 mA,最大两端电压约 2.5 V。在设计中避免长期超过此范围,以防因局部过热引起阻值漂移或失效。
  3. 阻值公差与温漂:±5% 的公差适合一般偏置与上拉应用;若电路对匹配或精度要求高,应选择更高精度或使用分立精密电阻。温度系数 ±200 ppm/℃ 表明中等温漂特性,长期温度变化会引起可观阻值变化(例如 50℃ 温差下约 1% 的变化)。
  4. 焊接工艺:遵循 UNI-ROYAL 的推荐回流焊温度曲线进行焊接,避免超温或长时间热暴露导致器件性能退化。存储与湿敏等级请参考供应商资料。
  5. PCB 布局:为减少热积聚与保证机械强度,注意焊盘设计与过孔排布;对需更好热散的场合,可在焊盘下方或邻近铺铜并连通地层以帮助散热(在不会改变电路功能的前提下)。

六、典型替代与采购提示

  • 采购时确认完整型号与数据手册,核对电阻内部联系(是否为独立电阻、是否有公共端等),以免与应用预期不符。
  • 若需要更高功率、精度或更小温漂,可考虑更高规格的网阻或分立电阻方案;若对 PCB 空间要求极高,可比较其他封装规格(如 0805x4 等)。

结论:4D03WGJ0101T5E(UNI-ROYAL)为一款面向低功耗信号与偏置场景的实用型四位排阻,优势在于体积小、装配方便与成本受控。设计时需注意其功率与温漂限制,合理做功率降额与散热设计可保证长期稳定运行。若需更详细的封装尺寸、回流曲线或可靠性数据,请索取厂方 Datasheet 以完成最终设计验证。

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.
