0402WGF7500TCE 产品概述

一、产品简介

0402WGF7500TCE 为 UNI-ROYAL(厚声)品牌的贴片厚膜电阻,封装为 0402(公制:1005或近似),标称阻值 750Ω,精度 ±1%,额定功率 62.5mW,最大工作电压 50V,温度系数(TCR) ±100ppm/℃,工作温度范围 -55℃ ~ +155℃。该型号在体积极小的同时提供较高的稳定性与可靠性,适合对空间和成本有严格要求的通用电子产品。

二、主要参数(要点)

  • 阻值:750Ω
  • 精度:±1%
  • 功率:62.5mW(额定功率,实际使用需考虑降额)
  • 最大工作电压:50V(器件允许的最大电压)
  • TCR:±100ppm/℃(温度变化对阻值的影响)
  • 工作温度:-55℃ ~ +155℃
  • 封装:0402,厚膜工艺

三、使用与设计要点

  • 功率与电压关系:按功率限制计算,连续使用时通过电阻的最大直流电压约为 V = sqrt(P·R) ≈ 6.85V。即使器件标称工作电压为 50V,长期连续工作时仍需确保不超过由功率决定的安全电压范围,或遵循厂方降额曲线。
  • 温度影响:TCR ±100ppm/℃ 表示每升高 1℃,阻值变化约 0.075Ω(对 750Ω)。在大温差环境下,温度引起的阻值漂移需纳入精度预算;温差接近 100℃ 时漂移约 1%。
  • 噪声与稳定性:厚膜电阻在成本-性能比上优越,适合大部分测量和限流场景;若需极低噪声或超高稳定性,应优先考虑薄膜电阻。

四、典型应用场景

  • 移动设备和可穿戴设备中的信号调理、分压器、偏置网络
  • 通用消费电子、工控和汽车电子的电阻网络、测量电路(需按车规评估)
  • 空间受限的模拟/数字混合电路、滤波器、升降压控制回路等

五、PCB布局与焊接建议

  • 遵循厂方或 IPC 推荐的焊盘与回流工艺,控制回流峰值温度与保温时间,避免长期高温暴露导致可靠性下降。
  • 0402 封装对焊盘尺寸和焊膏用量敏感,建议样片验证焊接良率并调整贴装参数。
  • 对大电流或高功率应用,考虑散热路径与周边铜层面积以改善散热性能。

六、储存与可靠性

  • 建议在干燥、常温条件下储存,避免潮湿与强污染环境。
  • 出于可靠性考虑,关键产品在应用前应通过温度循环、湿热、振动和焊接后阻值稳定性等验证。

七、选型提示

  • 若电路中电阻两端长期施加较高电压,请以功率限制计算允许电压或咨询厂方降额曲线与脉冲承受能力。
  • 对精密度、低噪音或高温稳定性有更高要求时,比较厚膜与薄膜、电阻功率和 TCR 后再决定。
  • 具体封装尺寸、焊接参数与可靠性试验结果,请参照厂家 datasheet 或直接联系 UNI-ROYAL 获取完整技术资料。

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
