0402WGJ0472TCE 产品概述
一、产品简介
0402WGJ0472TCE 为 UNI-ROYAL（厚声）系列厚膜贴片电阻，封装为0402（公制1005）。标称阻值为 4.7kΩ，公差 ±5%，额定功率 62.5mW，最大工作电压 50V。温度系数为 ±100ppm/℃，工作温度范围 -55℃ 至 +155℃，适用于高密度 SMT 贴装场景的通用信号与分压电路。
二、主要特性
- 封装小巧：0402 超小尺寸，利于高密度布板与微型化产品设计。
- 稳定性：采用厚膜工艺，具有良好的长期稳定性与一致性。
- 宽温区工作：-55℃~+155℃，可满足工业级温度要求。
- 温漂控制：±100ppm/℃，在温度变化下性能可预测，适合一般电子及滤波场合。
- 额定电压与功率：50V 最大工作电压、62.5mW 额定功率，适用于低功率信号链路。
三、典型应用
- 手机、可穿戴设备、便携式电子产品的信号/分压网络。
- 工业控制与仪器中的通用限流、分压和偏置元件。
- 消费类电子产品的滤波、阻抗匹配与旁路电路。
- IoT 与传感节点等对体积与可靠性有要求的方案。
四、封装与装配建议
- 贴片形式，适配自动测试及高速贴装机。
- 推荐采用标准回流焊工艺进行焊接，遵循元件厂商及焊料供应商的温度曲线与时间限制，避免长时间超温暴露。
- 设计时应考虑功率去率（derating），避免接近额定功率持续工作以延长可靠性。
五、可靠性与品质注意事项
- 厚膜电阻对冲击与振动具有良好耐受性，但在极端机械应力下仍需通过合理夹持与布局降低应力集中。
- 在高湿或化学腐蚀性环境中建议采取防护涂层或封装保护措施。
- 采购时建议确认批次与质量检测报告（阻值分布、寿命测试、耐焊性等）以保证一致性。
如需替代型号、详细规格书（阻值容差分布、潮湿测试、焊接曲线）或样品与带卷包装信息，可提供更多需求以便进一步查询。

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.
