0402WGF4122TCE 产品概述
一、概述
0402WGF4122TCE 为 UNI-ROYAL（厚声）生产的贴片厚膜电阻，阻值 41.2kΩ，精度 ±1%，额定功率 62.5mW，额定工作电压 50V。封装为 0402（约 1.0mm × 0.5mm），工作温度范围宽（-55℃ ~ +155℃），适用于体积受限的 SMT 应用。
二、主要参数
- 电阻类型：厚膜（Thick film）贴片电阻
- 阻值：41.2kΩ
- 精度：±1%（适合 E96 类精度等级应用）
- 额定功率：62.5mW（请以厂家规格书标注基准温度为准）
- 工作电压：50V（长期允许电压，两端最大持续电压）
- 温度系数（TCR）：±100ppm/℃
- 工作温度：-55℃ ~ +155℃
- 封装：0402（约 1.0 × 0.5 mm）
- 品牌：UNI-ROYAL（厚声）
三、技术特点
- 体积小、适合高密度贴片组装。
- 成本低、批量一致性好，适合大众电子产品。
- 厚膜工艺使得抗浪涌和抗机械应力性能较好，但 TCR 和噪声性能不及金属膜电阻。
- 宽温度范围和较高的耐热性，适合多种环境应用。
四、典型应用
- 手持设备、可穿戴、物联网终端等空间受限的消费类电子。
- 拉/下拉电阻、偏置网络、滤波电路中的通用阻值应用。
- 非关键精密信号通道（若要求更高温漂或低噪声，应选金属膜或薄膜电阻）。
五、封装与焊接建议
- 采用标准 SMT 搬运与回流焊工艺；遵循 JEDEC/J-STD-020 温升曲线，避免骤冷骤热。
- 建议使用厂家推荐的回流峰值温度（通常不超过 260℃），并控制焊接时间以降低热应力。
- PCB 焊盘尺寸、锡膏印刷量和热铜块面积会影响散热与额定功率，设计时需考虑功率衰减与热量分布。
六、选型与注意事项
- 若电路中有长期高电压或接近 50V 的情况，请确认实际最大工作电压和瞬态要求。
- 对温漂、长期稳定性或低噪声有较高要求的精密通路，建议选用更高等级的薄膜/金属膜电阻。
- 查询并参照 UNI-ROYAL 的完整规格书（datasheet）以获取额定功率基准温度、阻值温漂曲线、耐焊性与可靠性试验数据。
七、包装与合规
- 0402 规格通常以卷带（Tape & Reel）方式交付，便于 SMT 自动化贴装。
- 产品一般符合无铅 RoHS 要求；具体合规证书请向供应商或规格书确认。
如需样品、完整 datasheet 或在高速/高精度电路中的替代建议，我可以帮助提供进一步的选型与布局建议。

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.
