0402WGF2940TCE 产品概述
一、产品简介
0402WGF2940TCE 是 UNI-ROYAL（厚声）系列贴片厚膜电阻，阻值为 294Ω，精度 ±1%，功率额定 62.5mW（1/16W），工作电压 50V，温度系数（TCR）为 ±100ppm/℃，工作温度范围 -55℃ 到 +155℃。该器件采用 0402 封装（约 1.0mm × 0.5mm），适用于对尺寸、精度和可靠性有较高要求的小型电子产品。
二、主要特点
- 精度高：阻值公差 ±1%，适合高精度分压、信号调理等电路；
- 稳定性好：厚膜工艺结合严格的生产与筛选流程，长期漂移小；
- 宽温适应：-55℃ 至 +155℃ 的工作温度，适应工业级环境；
- 低功率但适配微型化：额定功率 62.5mW，适合便携、消费类及小型模块设计；
- 标称电压 50V，可满足常见低压电子系统的电压要求。
三、典型电气参数
- 阻值：294Ω
- 精度：±1%
- 额定功率：62.5mW（1/16W）
- 绝缘工作电压：50V
- 温度系数：±100ppm/℃
- 工作温度：-55℃ ~ +155℃
- 封装：0402（约 1.0mm × 0.5mm）
- 工艺：厚膜电阻
四、应用场景
- 手持设备与可穿戴电子的信号分路、限流与阻抗匹配；
- 工业控制、小型传感模块的阻值网络与偏置设计；
- 通信设备与仪器仪表中对体积与精度有权衡要求的电路；
- 汽车电子（非高功率节点）与消费电子低功耗电路。
五、封装与工艺建议
- 封装形式适用于自动贴装（SMT）、回流焊工艺，建议按照产品无铅回流温度曲线进行焊接；
- 存储与使用时避免长期潮湿环境，贴片卷盘应在回流前进行预烘（如按潮湿敏感等级要求）；
- 设计板上应考虑热散逸与功率限制，避免超过额定功率导致阻值漂移或失效。
六、可靠性与使用注意
- 遵循额定电压和功率限制，避免长期过载；
- 高频率或脉冲应用应评估瞬态热应力；
- 对于极端环境或严格长期稳定性需求，建议进行样机测试验证。
0402WGF2940TCE 提供在微型化设计中兼顾精度与可靠性的解决方案，适合多类别电子产品的标准化阻值需求。如需样片、卷盘包装或更详尽的可靠性数据与焊接规范，可联系供应商获取完整技术资料。

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.
