0402WGF2433TCE 产品概述
一、产品简介
0402WGF2433TCE 为 UNI-ROYAL（厚声）品牌的贴片厚膜电阻，封装为 0402（公制 1005），标称阻值 243 kΩ，精度 ±1%，额定功率 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℃～+155℃。该器件面向对体积、精度及稳定性有要求的小型化电子产品设计。
二、主要电气参数
- 阻值：243 kΩ（±1%）
- 额定功率：62.5 mW（室温标称）
- 额定工作电压：50 V（最大允许工作电压，应以此为准）
- TCR：±100 ppm/℃（典型温度漂移指标）
- 工作温度：-55℃ ～ +155℃
注：在 50 V 条件下，电阻两端功耗约为 10.29 mW（P = V^2/R），通过该电压时电流约为 205.8 μA；理论按功率计算的极限电压约 123.3 V，但请勿超过厂商规定的 50 V 工作电压等级。
三、性能特点
- 小型化：0402 封装，适合高密度 PCB 设计与便携设备。
- 精度高：±1% 满足大多数精密分压、偏置与时间常数电路需求。
- 稳定性：厚膜工艺在温度循环与振动下具有良好可靠性。
- 宽温区：支持 -55℃～+155℃ 的工业级工作温度。
四、典型应用场景
- 高阻值偏置/分压网络与输入阻抗较高的测量电路。
- 低功耗便携设备、传感器前端、滤波与时间常数网络（R-C）。
- 精密模拟电路中的高阻值连接与泄放路径。
五、设计与选型建议
- 严格控制两端电压 ≤50 V；虽然按功率计算电压上限更高，但封装与工艺限制以额定工作电压为准。
- 注意 TCR 带来的温度漂移：±100 ppm/℃ 在温差 70℃ 时约引起 0.7% 的阻值变化，设计时应考虑温度补偿或选择更低 TCR 的型号。
- 高阻值电路需注意 PCB 污染、电介泄漏与爬电距离，建议使用洁净焊接与适当的涂覆、保护措施（如涂层或防焊）。
六、封装、焊接与储存
- 封装：0402 标准片式，兼容自动贴装与回流焊工艺。
- 焊接：兼容常规无铅回流焊，请遵循厂家回流曲线，避免峰值温度超长停留以保持可靠性。
- 储存：置于干燥、防潮环境；大批量贴片器件建议防潮包装并在规定期限内使用。
七、可靠性与检测
- 建议来料检验包括：常温阻值测试（25℃）、温漂验证（按 ±100 ppm/℃ 规格）、外观检查及焊接性测试。
- 在关键应用可要求厂方提供寿命测试、热冲击与湿热测试报告。
八、订购与支持
0402WGF2433TCE 可按卷带（Tape & Reel）或散装方式供应，具体包装、最小包装量（MOQ）与交期请联系 UNI-ROYAL 正规代理或供应商获取。选型过程中如需更低 TCR、更高功率或更高电压等级，可咨询替代型号与定制化方案。

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.
