0402WGF820JTCE 产品概述

一、产品简介

0402WGF820JTCE 是 UNI-ROYAL(厚声)推出的一款0402尺寸厚膜贴片电阻。标称阻值为 82Ω,精度 ±1%,额定功率 62.5mW,工作电压 50V,温度系数(TCR)±200ppm/℃,工作温度范围 -55℃ 到 +155℃。该产品以厚膜工艺制成,体积小、成本低、适配高速表贴贴装生产线,适用于对空间和成本敏感的电子产品。

二、主要技术参数

  • 电阻类型:厚膜电阻(Thick film)
  • 阻值:82Ω
  • 精度:±1%(J)
  • 额定功率:62.5 mW(室温条件下)
  • 最大工作电压:50 V
  • 温度系数:±200 ppm/℃(典型)
  • 工作温度:-55℃ ~ +155℃
  • 封装:0402(约 1.0 × 0.5 mm)
  • 品牌:UNI-ROYAL(厚声)

三、关键性能与特点

  • 小体积:0402 尺寸适合高密度贴片、移动设备和便携式电子产品。
  • 精度较高:±1% 满足多数模拟信号与分压、限流等精度要求。
  • 良好温度特性:±200ppm/℃ 在多数商用/工业环境下可保持稳定阻值变化。
  • 稳定可靠:厚膜工艺在一般环境应力下表现出良好的长期稳定性与抗湿热能力。
  • 经济性强:制造成本低、适合大批量生产与应用。

四、典型应用场景

  • 移动终端、蓝牙耳机、可穿戴设备等受限空间的电源与信号限流。
  • 精密分压电路、参考电阻、阻抗匹配与滤波网络中的常规阻值单元。
  • 工业控制、仪表、传感器前端的低电压、小电流场合。
  • 高密度 PCB 设计中的通用电阻需求场景。

五、安装与焊接注意事项

  • 采用标准贴片工艺进行回流焊接;推荐按制造商回流温度曲线执行,避免过度回流或重复高温。
  • 由于0402体积小、额定功率低,在高温环境或散热受限情况下应考虑功率降额使用;高温下的功耗能力会下降。
  • 焊接时避免机械应力集中(如强烈碰撞、弯曲基板),以免引起端焊裂纹或阻值漂移。
  • 清洗建议使用温和溶剂,避免长时间强腐蚀性化学品浸泡。

六、储存与可靠性建议

  • 建议干燥防潮包装存放,避免长期暴露在高湿度环境中。若为潮湿敏感器件(MSL)请按厂家说明回流前进行烘烤处理。
  • 常温常压保存可保证长期性能稳定;如需长期库存,建议周期性抽样做阻值和耐温试验验证。
  • 对于关键可靠性应用(如汽车、医疗),建议参照更严格的资格认证与应力测试结果选择元件等级。

七、选型与采购建议

  • 若电路存在较大浪涌电压、电流或长期高温工作,建议选择额定功率更高或采用更低 TCR 的金属膜/合金丝电阻件。
  • 采购时确认包装形式(卷带/盘装)、批次与出厂检验报告;如对温漂、短期稳定性有更高要求,可向供应商索取详细数据表与寿命试验记录。
  • 对于大批量生产,建议先在样机与目标工艺上做可靠性和焊接兼容性验证,确保一致性与良率。

0402WGF820JTCE 以其小尺寸、±1% 精度与厚膜成本优势,适合大多数对空间和成本敏感的通用电子设计场景。在高功率或严格温漂要求下,请根据实际工况选择更适合的电阻类型或采取相应降额设计。

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
