0402WGF1621TCE 产品概述

一、产品简介

0402WGF1621TCE为UNI-ROYAL(厚声)系列的贴片厚膜电阻,封装为0402(约1.0 mm × 0.5 mm),阻值1.62 kΩ,精度±1%,额定功率62.5 mW。该器件采用厚膜制程,适用于对空间和成本敏感的表面贴装电路,具有良好的通用性与稳定性,适合手机、可穿戴设备、消费电子及一般工业电子线路中的电阻分流、分压、偏置等应用。

二、主要性能和规格

  • 电阻类型:厚膜电阻(贴片)
  • 阻值:1.62 kΩ(E96系列值,精度±1%)
  • 精度:±1%
  • 额定功率:62.5 mW(室温额定)
  • 最大工作电压(产品标称):50 V
  • 温度系数(TCR):±100 ppm/℃
  • 工作温度范围:-55 ℃ ~ +155 ℃
  • 封装:0402(公制约1.0 mm × 0.5 mm)
  • 品牌:UNI-ROYAL(厚声)

三、电气计算与使用注意

  • 功率与电压关系:器件长期允许的最大电压应同时满足额定电压和由功率与阻值决定的电压限制。按功率P与电阻R的关系 Vmax = sqrt(P × R)。对于本型号,理论由功率限制的连续电压约为: Vmax = sqrt(0.0625 W × 1620 Ω) ≈ 10.06 V 因此在连续工作情况下,应以约10 V为实际电压上限(同时不得超过标称的50 V绝缘/耐压限制)。
  • 温度降额:器件标注的62.5 mW为室温下的额定功率。随着环境温度上升,应按制造商功率降额曲线降载以保证可靠性,避免长期在高温下满载工作引起漂移或失效。
  • 噪声与稳定性:厚膜电阻在一般电路中稳定性良好,但对高精度、低失调噪声或长期零漂要求极高的场合,建议参考更低TCR或金属膜/薄膜电阻方案。

四、封装与 PCB 布局建议

  • 0402为微型SMD封装,适合高密度贴片布局。标准尺寸约1.0 mm × 0.5 mm,布线时应确保焊盘尺寸与制造工艺匹配。
  • 为减小热应力与焊接裂纹风险,焊盘不宜过大且应避免在元件两端产生显著的热梯度;贴装时推荐使用推荐的PCB land pattern并遵守回流焊工艺规范。
  • 对于高精度阻值的测量或配对应用,建议在布局时考虑温度自热与邻近热源的影响,必要时增加热隔离或采用恒流/恒温的测量方法。

五、典型应用场景

  • 移动终端:分压、限流、偏置与阻抗匹配
  • 消费电子:传感器前端、滤波/延时网络、分压器
  • 工业与仪器:通用电路阻值元件(非高精度参考)
  • 低功耗设备:因其微型化与较低功耗特点,适合低电流/低电压的便携式设备

六、焊接与可靠性建议

  • 推荐采用无铅或有铅回流焊工艺,遵循制造商的回流温度曲线以避免过热导致电阻漂移或机械损伤。
  • 存储与搬运时注意防潮、防机械冲击;0402体积小,易受搬运应力影响,贴片过程中避免刮擦和掉落。
  • 对于在高温、潮湿或有化学腐蚀环境中长期使用的场合,建议向供应商确认具体的可靠性测试(如温度循环、湿热老化、焊接可靠性)数据。

七、选型与采购参考

选择0402WGF1621TCE时,应确认目标应用的最大工作电压与实际电流是否满足由功率与阻值计算出的安全范围,考虑环境温度对功率降额的影响。若需更低TCR或更高功率、汽车级别可靠性(AEC-Q)认证,请向UNI-ROYAL(厚声)获取相应系列或替代型号的详细数据表与认证信息。

如需完整数据表、封装图或回流焊曲线,可联系供应商索取0402WGF系列的详细资料以便工程验证与量产设计。

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.
