0402WGF2152TCE 产品概述

一、主要参数与型号说明

0402WGF2152TCE 是 UNI-ROYAL(厚声)系列的 0402 封装厚膜贴片电阻,主要参数如下:

  • 阻值:21.5 kΩ
  • 精度:±1%(F)
  • 额定功率:62.5 mW(典型 0402 级别)
  • 最高工作电压:50 V(器件最大耐压,使用时需同时考虑功耗限制)
  • 温度系数(TCR):±100 ppm/°C
  • 工作温度范围:-55 ℃ 至 +155 ℃
  • 封装:0402(公制 1005)
  • 品牌:UNI-ROYAL(厚声)
    描述:贴片电阻 62.5 mW,21.5 kΩ,±1%,厚膜电阻。

二、性能要点与计算提示

  • 功耗与电压关系:尽管器件标称最大工作电压为 50 V,但在此电压下若全部加在单只 21.5 kΩ 电阻上,产生的功耗为 V^2/R = 50^2/21500 ≈ 116 mW,已超过器件额定功率 62.5 mW。因此实际应用中应同时满足电压和功耗限制。按额定功率计算,单只电阻允许的最大连续电压约为 √(P·R) ≈ 36.6 V,对应最大连续电流约 1.705 mA。
  • 温漂与精度:TCR ±100 ppm/°C 表示温度每变化 1 ℃,阻值变化约 0.01%,在温度变化较大或高精度测量场合需考虑温度补偿或选用低 TCR 器件。
  • 厚膜特性:厚膜电阻成本低、适用于通用电子产品,但在噪声、长期稳定性和温漂上不及金属膜或合金膜电阻。

三、适用场景

  • 一般电子产品中的分压、电阻网络、偏置电路与滤波电路。
  • 空间受限且电流/功耗较低的便携设备、移动终端、传感器模块、消费类电子与工业控制的小信号电路。
  • 不推荐用于要求极高稳定性、低噪声或高脉冲能量场合(例如精密测量、低频噪声敏感电路、功率分流)。

四、焊接与可靠性建议

  • 采用常规回流焊工艺贴装。建议参考厂商数据表中的回流曲线;避免超过器件的最大回流峰值温度与时长。
  • 安装时应避免过度机械应力与弯曲,焊盘设计遵循 0402 推荐焊盘尺寸以保证良好焊接强度与热散。
  • 对于潮湿敏感性(MSL)和焊前烘烤需求,请遵循供应商出货说明。清洗时避免使用强腐蚀性溶剂。

五、选型与替代方案

  • 若需更高功率或更好温漂,可考虑更大封装(0603、0805)或金属膜/薄膜电阻。
  • 若电路中会承受较高电压或脉冲,建议使用多并联/串联分担功耗或选用额定功率更高的器件。
  • 对于精密应用,选用 TCR ≤ ±25 ppm/°C、长期稳定性更好的薄膜器件。

六、注意事项与应用提示

  • 设计时同时校验电阻两项约束:不超过最大工作电压和不超过额定功耗。
  • 长期在高温(接近 +155 ℃)或频繁热循环环境下运行可能影响寿命与阻值漂移,必要时增加热保护或改用更耐温元件。
  • 采购时确认批次、包装、数据表和可靠性测试(如耐焊接测试、湿热、温度循环等)以满足具体应用要求。

总结:0402WGF2152TCE 以其 0402 小体积和 ±1% 精度适合空间受限且对功耗要求不高的通用电子应用。设计时务必关注电压与功耗配比、温漂影响以及焊接工艺,必要时通过并联/串联或更换封装以满足更高的电流/功率需求。

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
