4D03WGJ0331T5E 产品概述 — UniOhm 台湾厚声 RA_0603X4
一、产品简介
4D03WGJ0331T5E 为 UniOhm（台湾厚声）出品的 0603x4 四合一片式电阻网络，封装标识 RA_0603X4。每片内含 4 个独立阻值为 330Ω 的电阻元件，适用于空间受限且需多路电阻匹配的电子电路。
二、主要参数
- 阻值：330Ω（单体）
- 精度：±5%
- 单个元件额定功率：62.5 mW
- 温度系数（TCR）：±200 ppm/°C
- 引脚数：8（四个独立元件）
- 封装：0603x4（RA_0603X4）
三、产品特点
- 高度集成：四合一设计节省 PCB 占位面积与装配工序。
- 稳定性良好：TCR ±200 ppm/°C 适合中低速信号与偏置场合。
- 通用精度：±5% 满足大多数常规电路设计需求。
- 统一额定功率：每通道 62.5 mW，便于电热管理与并联/分配设计。
四、电气应用建议
- 常用于拉高/拉低电阻、限流、分压网络、阻抗匹配与信号终端。
- 在需要多路一致性但非高精度的便携设备、消费电子与工业控制中表现优良。
- 设计时建议考虑功率降额与热耦合，避免长期在额定功率附近工作。
五、封装与焊接
- 封装规格 0603x4，适配常见贴片贴装与回流焊工艺。
- 推荐遵循通用无铅回流曲线及制造商焊接工艺指南，注意避免过冲温度与多次回流导致性能退化。
- 贴装时注意 PCB 焊盘设计与热平衡，保证焊点可靠性。
六、可靠性与储存
- 常温干燥环境下密封保存，防止潮湿与机械应力。
- 长期运行建议遵循良好散热设计并留有功率裕度以提升可靠性。
七、采购与替代
- 型号：4D03WGJ0331T5E，品牌：UniOhm（台湾厚声），封装：RA_0603X4。
- 选型时可依据阻值、精度、TCR 与功率对比其他厂商同类四合一阵列，若需更高精度或更大功率，应选择相应产品系列。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
