0402WGJ0304TCE 产品概述

一、产品简介

0402WGJ0304TCE 是 UNI-ROYAL(厚声)系列的贴片厚膜电阻,封装为 0402(1.0 mm × 0.5 mm)。标称阻值 300 kΩ,阻值精度 ±5%,额定功率 62.5 mW,最大工作电压 50 V。温度系数(TCR)为 ±100 ppm/℃,工作温度范围 -55℃ 至 +155℃,适用于对体积和成本有严格要求的高密度电路设计。

二、主要特性

  • 厚膜工艺,兼具成本效益与批量一致性;
  • 小型 0402 封装,便于高密度贴片和轻薄移动设备应用;
  • 阻值 300 kΩ,适合偏置、拉高/拉低、滤波与高阻网络;
  • ±5% 精度满足常规电路容差需求;
  • 宽温工作范围与 ±100 ppm/℃ 的温漂特性,适合商业和工业级温度环境。

三、典型应用

  • 移动终端与可穿戴设备的分压、偏置电路;
  • 传感器前端的上拉/下拉电阻与高阻滤波网络;
  • 模拟电路中的偏置与时间常数网络;
  • 通信设备、物联网节点等对体积要求高且对阻值精度为中等要求的场景。

四、可靠性与环境适应

该厚膜电阻在设计上能承受常见的热循环、湿热和机械震动条件,工作温度范围覆盖从低温启动到高温工作需求。为保证长期稳定性,建议遵循厂商推荐的焊接工艺和降额使用准则。

五、使用建议

  • 焊接:推荐使用回流焊,按无铅或有铅回流曲线合理控制峰值温度与时间;避免反复高温回流;
  • 降额:建议在高温或持续发热条件下按厂商功率-温度曲线进行降额使用,常见做法是在高工况下将额定功率控制在 50%~70% 区间以提高可靠性;
  • 布局:避免在器件两侧施加过大机械应力,焊盘设计和阻焊开窗需符合 SMT 装配规范;
  • 清洗与维护:可按标准 PCB 清洗工艺处理,避免腐蚀性化学物质长期作用于电阻表面。

六、选型与替代建议

0402WGJ0304TCE 适合需要 300 kΩ 且占板面积极限受限的场合;若需更高精度或更高功率,应考虑更大封装或薄膜/金属薄膜型号。选型时综合考虑温漂、功率余量与长期稳定性,确保满足系统寿命要求。

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.

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
