0402WGF1433TCE 产品概述
一、产品简介
0402WGF1433TCE 是 UNI-ROYAL（厚声）品牌的一款高可靠性贴片厚膜电阻，额定阻值 143kΩ，精度 ±1%，额定功率 62.5mW。其超小型 0402 封装适用于空间受限的高密度板级设计，适配消费电子、通信模块、传感器及便携设备等应用场景，兼顾稳定性与可焊接性。
二、主要技术参数
- 阻值：143kΩ
- 精度：±1%（F）
- 功率（额定）：62.5mW（室温条件下）
- 工作电压：50V（最大）
- 温度系数（TCR）：±100 ppm/℃
- 工作温度范围：-55℃ ~ +155℃
- 阻值类型：厚膜电阻
- 封装：0402（公制 1005 英制）
- 品牌：UNI-ROYAL（厚声）
三、产品特性与优势
- 小型化设计：0402 封装极大节省 PCB 面积，适合高密度布线与多层板应用。
- 高精度与稳定性：±1% 精度配合 ±100 ppm/℃ 的 TCR，可满足对阻值稳定性有中高要求的电路设计。
- 宽温度适应：-55℃ 至 +155℃ 的耐温等级适应严苛环境与工业级应用。
- 良好焊接性：厚膜材料与终端电镀工艺适配常见回流焊工艺，贴装可靠。
- 可靠度高：厚膜工艺在应力与热循环下表现均衡，适合长期使用。
四、典型应用
- 精密分压、偏置网络与滤波电路
- 便携式消费电子（手机、可穿戴）阻抗匹配与偏置设计
- 通讯设备与射频模块的直流偏置/反馈电阻（需注意功率与电压限制）
- 传感器前端及模数转换输入网络
五、封装与机械说明
0402 封装体积小，适合自动贴片生产线。设计 PCB 拓扑时应考虑热量分布及邻近器件对散热的影响。推荐遵循厂商提供的封装尺寸与回流焊温度曲线，以保证焊接可靠性与阻值稳定性。
六、选型与使用建议
- 功率裕量：额定功率 62.5mW，为保证可靠性，实际使用功耗应留出足够裕量（通常不超过额定的 50%~70%），并考虑热阻与 PCB 散热状况。
- 电压限制：单个元件最大工作电压 50V，设计时应避免超过该值以免引起击穿或阻值漂移。
- 温漂与精度：对于高精度测量电路，注意 ±100 ppm/℃ 的温漂对温度变化敏感度，必要时采用温度补偿或选用更低 TCR 的产品。
- 贴装工艺：严格按回流曲线操作，避免重复高温循环；除湿处理与防潮包装可防止焊接缺陷。
七、可靠性与环境适应
0402WGF1433TCE 设计满足常见的环境可靠性要求，包括高低温循环、焊接热稳定性与机械震动冲击等。其材料和工艺适用于工业级温度范围，具体认证（如 AEC-Q 或 RoHS 等）请以厂方出具的检验报告为准。
总结：0402WGF1433TCE 以其超小封装、较高精度与宽温度适应性，适合空间受限且对阻值稳定性有中等要求的电子产品。选型时应综合考虑功率裕量、电压限制与工作环境，确保长期可靠运行。若需进一步的封装尺寸图、回流焊资料或认证文件，可向供应商索取详尽技术资料。

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.
