0402WGF1502TCE 产品概述

一、产品简介

0402WGF1502TCE 是 UNI-ROYAL(厚声)推出的一款贴片厚膜电阻,阻值 15kΩ,精度 ±1%,额定功率 62.5mW,封装为 0402(常规尺寸 1.0mm × 0.5mm)。产品适用于体积受限的高密度贴片电路,兼顾成本与中等精度需求。

二、主要电气与环境参数

  • 阻值:15kΩ
  • 精度:±1%(色环/标称)
  • 额定功率:62.5mW(室温)
  • 额定工作电压:50V(绝缘/耐压参考值,详见下文)
  • 温度系数(TCR):±100 ppm/°C
  • 工作温度范围:-55°C 到 +155°C
  • 封装:0402(1.0mm × 0.5mm,厚度随厂商略有差异)

三、重要性能解读

  • 功率与电压需同时考虑:按 P = V^2/R 计算,在 P=62.5mW、R=15kΩ 时,连续工作下的最大电压约为 V = √(P·R) ≈ 30.6V。虽然标称“工作电压 50V”,但在持续功率限制下不宜在 50V 下长时间施加电压,否则会超出功耗能力引起升温甚至失效。设计时应同时检查电压与功率两项约束。
  • 温漂影响:TCR ±100 ppm/°C 意味着每升高 1°C,阻值变化约 15kΩ × 100e-6 = 1.5Ω。举例从 25°C 到 85°C(ΔT=60°C),阻值变化约 90Ω,约占标称值的 0.6%。对高精度或高稳定性电路需评估温度引起的漂移。
  • 封装限制:0402 尺寸小,热散能力有限,不适合高功率或频繁脉冲大电流场合;同时对贴装工艺(焊膏量、回流曲线)敏感,需优化以避免 tombstoning 或虚焊。

四、典型应用场景

  • 移动终端、可穿戴设备的偏置电阻与分压网络;
  • 模拟前端的基准分压、滤波器与增益设定(对 1% 阶段电阻有良好适配);
  • 工业与消费类电子中对体积、成本有严格要求但对温漂容忍度在可接受范围内的电路。

五、封装与装配建议

  • 贴片与包装:提供行业标准的卷带托盘(Tape & Reel),便于飞针/贴片机上料;
  • 回流焊:建议遵循 UNI-ROYAL 推荐的回流曲线或 IPC/J-STD-020 规范,峰值温度通常 ≤ 260°C;控制升温速率和峰值停留时间以减少热应力;
  • 焊膏与锡膏印刷:使用适合 0402 的锡膏模板开口,均匀焊膏量可降低 tombstoning 风险;
  • 机械/热应力:在波峰或手工焊接时避免长时间加热,避免对元件施加侧向机械力。

六、可靠性与品质控制

UNI-ROYAL 产品通常进行出厂电阻值筛选、耐焊接热冲击、机械应力、湿度与盐雾等常规可靠性测试。量产选型时建议向供货方索取详细的检验报告(ELP/质量合规文件)以满足项目可靠性要求。

七、选型注意与使用建议

  • 若电路可能承受接近或超过 30V 的连续电压,应基于功率计算并考虑选用功率更高或阻值更大/串联分压方式;
  • 对精密测量或温度敏感应用,考虑使用低 TCR(金属膜或薄膜电阻)替代;
  • 设计时预留足够的热裕度并参考厂商功率-温度降额曲线;
  • 采购时明确包装、检验与可追溯性要求,必要时做样件寿命测试。

总结:0402WGF1502TCE 以其 0402 超小封装、15kΩ/±1% 的组合,适合对面积敏感且要求中高精度的常规电子应用,但在电压、功率与温漂方面须谨慎评估并做恰当的热与电气降额设计。若需更详细的回流曲线、封装三视图或可靠性测试报告,可向供货商索取原始数据手册。

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
