0402WGF3302TCE 产品概述

一、产品简介

0402WGF3302TCE 是 UNI‑ROYAL(厚声)推出的一款高密度贴片厚膜电阻。该器件为 0402 小封装(约 1.0 mm × 0.5 mm),标称阻值 33 kΩ,精度 ±1%,额定功率 62.5 mW(1/16W),工作电压 50 V,温度系数 ±100 ppm/℃,工作温度范围 −55℃ 至 +155℃。此型号以体积小、成本友好、可靠性良好为特点,适合空间受限的高密度电路板与通用电子应用。

二、主要性能参数

  • 阻值:33 kΩ(标称)
  • 精度:±1%
  • 类型:厚膜贴片电阻
  • 额定功率:62.5 mW(1/16 W,0402)
  • 最大工作电压:50 V
  • 温度系数:±100 ppm/℃
  • 工作温度范围:−55℃ ~ +155℃
  • 封装:0402(表面贴装)
  • 品牌:UNI‑ROYAL(厚声)

三、结构与封装特色

0402WGF3302TCE 采用厚膜工艺制造,电阻体由金属氧化物浆料经印刷和烧结形成,端接为金属化电极,表面有保护涂层以提高抗潮湿和耐焊性。0402 尺寸小,适用于高密度 SMT 布局。厚膜电阻在常温下表现稳定,具有良好的机械强度和可量产性。

四、设计与焊接建议

  • 焊接工艺:推荐采用符合无铅回流焊标准的焊接曲线(按 J‑STD‑020/IPC 指南)。在回流过程中应严格控制峰值温度和升温时间,遵循厂家具体回流曲线以避免性能退化。
  • 热降额:在高环境温度下需按厂家提供的功率降额曲线处理。一般 0402 的额定功率是在较低环境温度下测得,随温度上升需线性降额处理以保证可靠性。
  • PCB 布局:为减少“浮立”(tombstoning)风险,建议焊膏量左右均衡,焊盘形状对称;焊盘尺寸与焊膏印刷应参考制造商或 IPC 推荐的 0402 焊盘设计指南。
  • 清洗与保护:若电路板经历洗板或潮湿环境,建议在必要处采用涂覆保护层或环氧封装以提高长期可靠性。

五、典型应用场景

  • 移动设备与便携式电子(需高密度组装的电阻阵列)
  • 工业控制与仪表(宽温运行)
  • 通信终端与消费电子(滤波、分压、偏置网络)
  • 低功率模拟电路与数字电路中的通用电阻件
    注意:若有特殊可靠性要求(如汽车 AEC‑Q 认证或高能量冲击条件),请与供应商确认是否满足对应标准。

六、可靠性与环境特性

0402WGF3302TCE 工作温度范围宽(−55℃ 至 +155℃),适合在较严苛温度环境中长期使用。厚膜材料对湿热、热冲击具有较好承受能力,但具体寿命与可靠性仍依工况(如功耗、循环温度应力、焊接条件)而异。常见可靠性试验包括高温储存、热冲击、湿热试验及焊接耐久性测试,建议在产品导入前参考供应商的可靠性报告或自行作针对性验证。

七、选型与订购建议

下单时请注明完整型号 0402WGF3302TCE、阻值及精度要求、包装方式(带卷 tape & reel)和所需数量。常见卷带包装数量可按客户需求提供(如 5,000 或 10,000 颗/卷)。如需替代型号或不同温漂、功率等级,请与供应商技术支持沟通以获得最合适的替代方案。

总结:0402WGF3302TCE 以其小尺寸、1% 精度和宽温工作特性,适合高密度贴装与通用低功耗电路。采用前应关注回流焊工艺和功率降额设计,必要时进行针对性可靠性验证以确保在目标应用中的长期稳定性。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
