0402WGJ0300TCE 产品概述

一、产品简介

0402WGJ0300TCE 为 UNI-ROYAL(厚声)品牌的贴片厚膜电阻,封装尺寸为 0402(约 1.0 mm × 0.5 mm)。标称阻值为 30Ω,公差 ±5%,额定功率 62.5 mW,额定工作电压 50 V,温度系数(TCR)为 ±100 ppm/℃,工作温度范围 -55℃~+155℃。该器件适合高密度表贴装配的通用电阻应用,兼顾体积微小与成本效益。

二、主要技术参数

  • 型号:0402WGJ0300TCE
  • 品牌:UNI-ROYAL(厚声)
  • 封装:0402(英制)≈1.0 mm × 0.5 mm
  • 电阻类型:厚膜电阻
  • 阻值:30Ω
  • 精度:±5%
  • 额定功率:62.5 mW(典型0402功率等级)
  • 工作电压:50 V(最大工作电压)
  • 温度系数:±100 ppm/℃
  • 工作温度:-55℃~+155℃
  • 适用工艺:表面贴装,兼容常见回流焊工艺
  • 环保属性:符合常见环保/RoHS 要求(请根据采购批次确认认证文件)

三、性能特点

  • 小型化:0402 尺寸适配高密度 PCB 布局,空间利用率高,适合小型化电子产品。
  • 成本效益高:厚膜工艺生产成本低,适用于大批量通用电阻需求。
  • 温度稳定性:±100 ppm/℃ 的 TCR 在通用类电路中表现稳定,适合对温漂要求不高的场合。
  • 功率与电压匹配:62.5 mW 的功率适合信号路径、分压、上/下拉网络等低功耗场景;50 V 工作电压限制了其在高压应用中的直接使用。
  • 工艺兼容性:适用于常规 SMT 贴装与回流焊流程,适合自动化生产线。

四、典型应用场景

  • 移动终端与便携设备中作分压、电流限流、上/下拉电阻使用。
  • 消费电子、智能家居、可穿戴设备等对体积要求高且功耗低的场合。
  • 数字信号链路的终端电阻、阻抗匹配(在允许的功率和阻值范围内)。
  • 大规模阵列中作为通用偏置或滤波网络元件(非精密测量场合)。

五、封装与焊接建议

  • 0402 的体积较小,建议使用与封装匹配的 PCB 焊盘和阻焊孔设计,保证良好焊接可靠性和可回流性。
  • 推荐采用自动贴装与标准无铅回流焊工艺,注意遵循 PCB 板级热特性与回流曲线的综合要求。
  • 装配过程中避免过度的机械应力(如弯曲、刮擦),以免引起端接裂纹或接触不良。

六、选型与使用注意事项

  • 功率与发热:0402 的额定功率在较高环境温度下需按厂商的降额曲线处理,长时间高负载会影响寿命。必要时可通过并联/串联或选用更大封装来提升功率承载能力。
  • 电压限制:工作电压不得超过 50 V,瞬态尖峰需考虑抑制或限制,以防绝缘击穿或失效。
  • 精度与漂移:±5% 精度及 ±100 ppm/℃ TCR 适合通用类电路,不建议用于高精度测量或严格温度稳定性的场合。
  • 环境耐受:若产品用于高湿、高盐雾或严苛工业环境,建议与供应商确认相应的可靠性测试及封装防护等级。

七、可靠性与质量保证

UNI-ROYAL(厚声)作为成品供应商,0402WGJ0300TCE 依行业常规工艺生产并通过常规可靠性验证项(如焊接性、温循环、湿热等)以确保批次稳定性。采购时建议索取具体的产品规格书(Datasheet)与可靠性测试报告,以便满足项目的认证与长期可靠性需求。

总结:0402WGJ0300TCE 是一款面向高密度组装、通用低功耗电路的经济型厚膜贴片电阻,适合大量量产与消费电子领域的标准阻值需求。在选型和使用时应注意功率降额、电压限制及环境耐受性,以保证长期可靠运行。

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
