0402WGF4990TCE 产品概述
一、概述与型号说明
0402WGF4990TCE 为 UNI-ROYAL（厚声）系列贴片厚膜电阻，封装尺寸为 0402（约 1.0 × 0.5 mm）。标称阻值 499Ω，公差 ±1%，适用于高密度贴装的微型电子设备与信号处理电路。标称功率 62.5 mW，额定工作电压 50 V，温度系数（TCR）±100 ppm/℃，工作温度范围 -55℃ 至 +155℃。
二、主要电气参数
- 阻值：499 Ω（±1%）
- 功率额定值：62.5 mW（典型封装功率等级）
- 最大工作电压：50 V
- 温度系数：±100 ppm/℃
- 工作温度：-55℃ ~ +155℃
- 制程类型：厚膜电阻（薄膜工艺外的经济型工艺，电阻稳定性与成本平衡）
三、关键特性与优势
- 超小封装，适合高密度贴片与便携设备设计；
- ±1% 精度满足多数信号、分压与阻抗匹配需求；
- TCR ±100 ppm/℃ 在中等温漂要求下能保持良好阻值稳定性；
- 宽工作温度范围适应工业级环境；
- 厚膜工艺具备成本优势，量产一致性好。
四、典型应用场景
适用于移动设备、通信终端、消费电子、传感器接口、分压/偏置网络、滤波与匹配电路等需要微型化、可靠电阻元件的场景。对于对温漂要求不极端严格、功耗较低的设计尤为合适。
五、使用与可靠性建议
- 建议按照制造商数据手册的焊接曲线进行回流焊，避免超温长时间加热；
- 在设计时考虑功率热耗与散热条件，避免长时间在额定功率下满载工作；
- 采用适当的封装焊盘设计和回流工艺，可提高焊接可靠性；
- 对于高精度或严格漂移要求的场合，可考虑并联/串联或选用更低 TCR 的产品。
六、包装与选型提示
产品通常以卷带（Tape & Reel）形式供应，便于 SMT 自动贴装。选型时注意工作电压与功率裕量、温度环境与长期漂移要求。如需替代或批量采购，可与 UNI-ROYAL（厚声）渠道确认最新数据手册与可靠性试验报告。

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.
