0402WGF4752TCE 产品概述

一、产品简介

0402WGF4752TCE 是 UNI-ROYAL(厚声)推出的一款高可靠性贴片厚膜电阻,阻值 47.5kΩ,精度 ±1%,额定功率 62.5mW,额定工作电压 50V。该器件采用 0402(公制 1005)超小封装,适用于空间受限且对稳定性、精度有较高要求的精密电子设备与便携终端。工作温度范围广(-55℃ ~ +155℃),温度系数 (TCR) 为 ±100ppm/℃,在各种环境下均能保持优良的性能表现。

二、主要参数与特性

  • 电阻类型:厚膜电阻(SMD)
  • 阻值:47.5kΩ
  • 阻值精度:±1%
  • 额定功率:62.5mW(在指定环境温度下)
  • 最高工作电压:50V
  • 温度系数:±100ppm/℃(典型)
  • 工作温度范围:-55℃ ~ +155℃
  • 封装:0402(1005公制)
  • 品牌:UNI-ROYAL(厚声)

主要特性:

  • 小尺寸、高密度装配友好,适配自动贴装与回流焊工艺;
  • ±1% 精度满足多种精密分压与偏置要求;
  • 宽温区与较小的 TCR 保证在温度变化条件下阻值稳定性良好;
  • 额定电压 50V,可用于中低电压信号回路。

三、典型应用场景

  • 移动通信与消费电子:手机、平板、可穿戴设备等的分压、偏置与阻抗匹配;
  • 工业与仪表:精密采样电路、ADC 前端的阻抗网络;
  • 汽车电子(非关键安全回路):信息娱乐系统、传感器接口(需根据车规级要求核验);
  • 低功耗信号处理与微功率电路:在功率受限场合提供可靠的阻值与温漂性能。

四、封装与包装信息

  • 封装:0402(长×宽约 1.0mm × 0.5mm),便于高密度贴装;
  • 包装形式:卷带(Tape & Reel),兼容主流贴片机自动上料;
  • 存储与运输:按行业标准防潮封装,建议按生产批次 FIFO 使用。

五、焊接与装配建议

  • 焊接工艺:推荐采用无铅回流焊工艺,遵循厂商提供的回流温度曲线,避免过高峰值温度和过长加热时间以减少热应力;
  • 洁净处理:回流后可根据板级清洗要求选用适当溶剂清洗,避免对电阻表面造成腐蚀或残留引起性能偏移;
  • 贴装注意:0402 为微小封装,贴装时注意吸嘴选择与位置校正,防止偏位或倾斜。

六、可靠性与质量控制

0402WGF 系列在出厂前通过常规电气与环境可靠性试验,典型测试包括:

  • 温度循环(Thermal Cycle)
  • 高低温储存与工作测试
  • 湿热/加速老化(HAST 或湿热测试)
  • 耐焊性与焊接热稳定性测试
  • 漏电与绝缘检查(对于高阻值场合)

以上测试确保在规范使用条件下产品的长期稳定性和可追溯性。具体认证与测试报告可向供应商索取。

七、注意事项与选型建议

  • 功率使用:0402 封装 62.5mW 为在特定环境温度下的额定功率,实际使用中应考虑温升与周围器件散热,必要时进行功率去率(derating)设计;
  • 电压限制:单片最大工作电压 50V,超出该电压可能引起击穿或长期漂移,应避免超额定值使用;
  • 温漂要求:±100ppm/℃ 适用于普通工业级应用,若对温漂有更高要求,应选择更低 TCR 的薄膜或金属膜电阻产品;
  • 汽车与极端环境应用:若用于关键汽车电子或航天类高可靠场景,请咨询厂商是否提供相应车规级或军规级产品线。

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
