0402WGF510JTCE 产品概述

一、主要参数与型号说明

0402WGF510JTCE 为 UNI-ROYAL(厚声)系列厚膜贴片电阻,封装规格为 0402(英制),电阻值 51Ω,公差 ±1%,额定功率 62.5mW,最高工作电压 50V,温度系数(TCR) ±100ppm/℃,工作温度范围 -55℃ ~ +155℃。该型号针对小尺寸、高密度贴装场景设计,兼顾精度与温度稳定性。

二、结构与工艺特点

本品采用厚膜工艺制成,具有制造一致性好、温度系数稳定、成本效益高等优势。0402 小封装在现代 SMT 工艺中广泛应用,适合高密度布局。电阻体与端电极材料及焊盘设计经过优化,保证良好的焊接性和机械可靠性。

三、性能与应用场景

凭借 51Ω ±1% 的精度和 ±100ppm/℃ 的温漂,本产品适用于对阻值精度有一定要求的场合,如阻抗匹配与终端负载、滤波与分压网络、一般信号链路的阻抗控制以及小功率消耗电路。0402 的小尺寸也适合移动设备、无线模块、消费电子与高密度 PCB 布局。

四、可靠性与环境适应

  • 工作温度范围宽(-55℃ ~ +155℃),适应工业级温度环境。
  • 在正常工作条件下具有良好的长期稳定性与重复性,但在高温或近额定功率长期工作时需考虑降额设计。
  • 建议在 PCB 设计与热管理上预留裕度,避免在高温环境下长期满载运行以延长元件寿命。

五、封装与工艺建议

  • 包装形式:标准卷带(Tape & Reel),便于自动贴装生产线使用。
  • 焊接兼容:适用于常规 SMT 回流焊流程。建议遵循生产工艺及厂家焊接曲线以避免过热应力。
  • 安装与处理:贴片安装时避免施加过大的机械应力,焊接后避免对封装进行弯曲或强力擦拭;储存环境保持干燥,避免潮湿和污染。

六、设计与选型注意事项

  • 功率降额:在高环境温度下需按系统热设计进行功率降额计算,留有安全裕量。
  • 电压与击穿:最高工作电压 50V,电路中使用时应保证实际施加电压在该范围内并考虑瞬态保护。
  • 阻抗匹配:51Ω 常用于接近 50Ω 系统的阻抗匹配或终端电阻选择,布线与封装寄生应一并考虑以保证高频性能。

总之,0402WGF510JTCE 为一款适用于高密度 SMT 应用的厚膜贴片电阻,兼顾体积小、精度高与温度稳定性,适合通信、消费电子及一般电子设备中需要 51Ω 精密阻值的场景。若需更详细的焊接曲线、寿命测试报告或批量包装信息,建议联系供应商索取完整数据手册。

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
