0402WGJ0750TCE 产品概述

一、产品简介

0402WGJ0750TCE 是 UNI-ROYAL(厚声)系列的一款贴片厚膜电阻,阻值为 75 Ω,阻值公差为 ±5%,额定功率 62.5 mW,典型封装为 0402(英制,1.0 mm × 0.5 mm 左右)。该产品采用厚膜工艺制成,适合超小尺寸电路的阻抗匹配、终端和一般分流/限流场合,兼顾体积优先与基本电气性能的需求。

二、关键技术参数

  • 电阻类型:厚膜电阻(贴片)
  • 封装:0402
  • 阻值:75 Ω
  • 阻值精度:±5%
  • 额定功率:62.5 mW
  • 最大工作电压:50 V(在该电压下切忌长时间超过额定功率)
  • 温度系数(TCR):±200 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 品牌:UNI-ROYAL(厚声)
    (以上参数为典型规格,最终选型请以厂家发布的最新数据手册为准)

三、主要特性与优势

  • 小型化:0402 封装尺寸极小,适合高密度 PCB 布局与空间受限的移动或便携设备。
  • 基础通用性:75 Ω 常用阻值,适配视频/同轴等 75 Ω 系统以及需要此阻值的模拟信号链路。
  • 温度适应性:宽工作温度范围(-55 ℃ 至 +155 ℃),适合严苛环境下使用。
  • 工艺稳定:厚膜工艺成本低、制造成熟,适合量产及成本敏感型产品。
  • 可靠性:符合常规电子元器件可靠性要求,适用于工业及消费类电子设备(具体可靠性指标请参考厂方试验报告)。

四、典型应用场景

  • 视频信号链的终端电阻与阻抗匹配(如闭路电视/CCTV、视频传输线路)。
  • 同轴及 RF 前端的阻抗校正与终端(在非高精度/高功率场合)。
  • 移动终端、机顶盒、数字信号处理模块中的通用限流或分压电路。
  • 传感器前端、接口保护及一般电子设备中的替换/分流电阻。

五、选型与使用建议

  • 功率余量:0402 的额定功率仅 62.5 mW,实际电路中应留有充足余量(建议工作点功率低于额定值的 50%~70%),并考虑散热与 PCB 布局对热阻的影响。
  • 电压限制:工作电压不超过 50 V;如电路中存在瞬态高电压或电弧风险需额外保护。
  • 精度与温漂:±5% 精度与 ±200 ppm/℃ 的温度系数适合一般应用,若需高精度或低漂移,请考虑薄膜或金属膜高精度元件。
  • 焊接工艺:推荐采用标准回流焊步骤,遵循厂商的焊接温度曲线与湿敏等级(MSL)要求,避免重复过热。
  • PCB 设计:0402 元件焊盘尺寸与过孔布局要符合 IPC 建议,以保证良好焊接与热传导;尽量避免与高功率元件紧邻以降低热负荷。

六、可靠性与检验

  • 常见可靠性测试包括耐焊接热、温度循环、湿热、机械应力(振动/跌落)及寿命老化测试。
  • 出厂检验通常涵盖阻值测量、绝缘耐压、外观检查及抽样老化。用户需依据最终应用场景向供应商索取详细可靠性测试报告与认证数据。

七、包装与订购建议

  • 0402WGJ0750TCE 通常以卷带(Tape & Reel)方式包装,便于 SMT 贴片机自动化装配。
  • 订购时请注明完整料号、批次及所需数量,并确认交货期与最小包装数量。大批量采购可向供应商申请样片和可靠性报告以供评估。

总结:0402WGJ0750TCE 以其小体积和常用 75 Ω 阻值在空间受限且对精度要求不高的场合具有良好适用性。选型时应重点关注功率与电压限制、温漂特性及焊接/布局对性能的影响,以确保长期稳定运行。若需更严格的电气或环境性能,请向 UNI-ROYAL 获取完整数据手册及测试认证资料。

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.

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
