0402WGJ047JTCE 产品概述
一、概述
0402WGJ047JTCE 为 UNI-ROYAL（厚声）品牌的贴片厚膜固定电阻，阻值 4.7Ω，精度 ±5%（J）。该型号采用 0402 超小封装，额定功率 62.5mW，额定工作电压 50V，适用于空间受限的消费电子、移动终端及高密度电路板的通用阻值需求。
二、主要参数
- 阻值：4.7Ω
- 精度：±5%（J）
- 功率：62.5mW（额定）
- 工作电压：50V
- 温度系数：±200ppm/℃
- 工作温度范围：-55℃ ～ +155℃
- 封装：0402（约 1.0mm × 0.5mm）
- 类型：厚膜电阻（贴片）
三、性能特点
- 体积小、重量轻，利于高密度布板与微型化设计；
- 厚膜工艺成本经济，适合大批量量产；
- 温度系数 ±200ppm/℃，在温度波动较小的场合能保证阻值稳定；
- 宽工作温度范围，适应工业级环境要求。
四、应用场景
- 移动设备、可穿戴设备的分压、限流、偏置电路；
- 各类传感器信号调节与阻抗匹配；
- 通信设备和消费电子的常规电阻配套元件；
- 需小封装、低功耗的高密度电路板设计。
五、使用与选型建议
- 额定功率 62.5mW 为 25℃ 下测定值，高温环境或受限散热时需降额使用；具体降额曲线建议参考厂家数据；
- 工作电压 50V，不可长期超过该值以避免绝缘或击穿问题；
- ±5% 精度适用于非高精度测量或容差可控的应用，若需更高精度请选用更低温漂或更高精度型号；
- 温度系数 ±200ppm/℃ 表示阻值随温度变化有一定漂移，温敏电路请谨慎评估。
六、焊接与可靠性
- 兼容常规回流焊工艺，但应按照厂方推荐的回流温度曲线和制程控制进行；
- 0402 小封装在手工焊接或返修时需注意热量控制与焊盘保护；
- 厚膜结构在抗冲击和耐湿性能上表现良好，但不适合承受高浪涌能量和长时间过载。
七、局限与注意事项
- 低额定功率限制了其在电源、功率耗散较大的场合使用；
- 对于高频精密匹配或低温漂场合，厚膜 ±200ppm/℃ 的特性可能不满足要求，应考虑薄膜或金属膜器件；
- 封装尺寸小，焊盘设计与贴装精度需与 PCB 制造/贴片设备相匹配。
八、包装与采购提示
- 常见为卷带（Reel）包装，便于 SMT 贴片；采购时确认料号 0402WGJ047JTCE 与包装单位（卷数/盘）一致；
- 建议向供应商索取完整规格书、回流曲线、降额曲线及可靠性测试报告以便设计验证。

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.
