0402WGF8201TCE 产品概述

一、产品概述

0402WGF8201TCE 是 UNI-ROYAL(厚声)系列的一款0402封装贴片厚膜电阻,标称阻值 8.2kΩ,精度 ±1%,额定功率 62.5mW(即 1/16W 级别),最大工作电压 50V,温度系数(TCR)±100ppm/℃,工作温度范围 -55℃ 至 +155℃。本产品适用于体积受限且对稳定性和一致性有较高要求的消费电子、通信、仪表和工业控制等领域。

二、主要参数

  • 阻值:8.2kΩ
  • 精度:±1%
  • 功率:62.5mW(典型器件额定)
  • 最大工作电压:50V
  • 温度系数(TCR):±100ppm/℃
  • 工作温度:-55℃ ~ +155℃
  • 封装:0402(国际尺寸代码,约 1.0mm×0.5mm)
  • 工艺:厚膜电阻工艺
  • 品牌:UNI-ROYAL(厚声)
    (注:具体终端电镀、包装方式及详细机械尺寸请以厂家规格书为准。)

三、产品特性与优势

  • 小型化封装:0402 封装满足高密度 PCB 布局需求,适合便携设备与紧凑型电路板。
  • 稳定性:厚膜工艺在一般使用条件下具有良好的长期稳定性和抗冲击能力。
  • 精度与温漂:±1% 精度配合 ±100ppm/℃ 的温度系数,能够满足多数精密分压、偏置及反馈网络的需求。
  • 工作温度宽:-55℃~+155℃ 的工作范围适合恶劣环境与工业级应用。
  • 兼容主流焊接工艺:适用于无铅回流焊流程(具体回流曲线请参照厂方建议)。

四、典型应用场景

  • 移动终端和可穿戴设备的电源分压与偏置电阻。
  • 通信设备中的信号处理与偏置网络。
  • 工业控制与传感器接口电路,要求长期稳定性的电阻网络。
  • 精密仪表中对阻值公差和温漂有一定要求的场合。

五、封装与焊接建议

  • 封装为 0402(尺寸约 1.0 × 0.5 mm),在 PCB 布局时应留足焊盘和阻焊间距以利于贴装与回流焊接。
  • 推荐遵循制造商给出的焊盘图与回流焊曲线,避免超过最大回流温度和时间累积。
  • 在高功率或高温环境下应注意器件的热降额,PCB 散热设计(如增加铜箔面积)有助于提升允许载流与稳定性。
  • 建议在设计阶段评估焊接后的机械应力与振动环境,必要时进行抗震防护设计。

六、可靠性与环境适应性

该厚膜电阻在典型规格下通过常规可靠性试验(如温度循环、湿热、机械冲击与焊接热稳性测试),适合商业与工业级应用。其工作温度范围与温漂指标保证了在宽温区间内的性能一致性。对于关键应用,建议查看厂家完整的可靠性验证数据与加速寿命试验报告。

七、选型与采购建议

  • 当电路对尺寸有限、但要求 ±1% 精度与中等温漂时,0402WGF8201TCE 是合适选择。
  • 若电路电压或功耗接近器件额定值,应考虑更大功率等级或通过并联/调整电路实现功率分摊。
  • 订购时确认包装形式(卷装、带盘等)、端接处理和认证需求(如有)以确保与生产工艺匹配。
  • 如需更低温漂或更高功率,请向厂商咨询相邻系列或定制规格。

如需技术规格书(Datasheet)、尺寸图或样品清单,我可以协助整理并列出与实际PCB布局、热设计相关的更详细建议。

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
