0402WGF1371TCE 产品概述

一、产品简介

0402WGF1371TCE 是 UNI-ROYAL(厚声)出品的一款厚膜贴片电阻,封装尺寸为 0402(公制 1005),标称阻值 1.37 kΩ,精度 ±1%,额定功率 62.5 mW(即 1/16 W),最大工作电压 50 V,温度系数(TCR)典型 ±100 ppm/°C,工作温度范围 -55 ℃ ~ +155 ℃。该系列产品结合小型化体积与稳定的电气性能,适合对空间和精度有一定要求的消费电子、通讯设备和工业控制类电子产品。

二、主要特性

  • 封装:0402(1005 公制),适用于高密度贴装与自动化贴装工艺。
  • 阻值:1.37 kΩ,公差 ±1%,适合精度要求较高的分压、偏置及滤波网络。
  • 功率:62.5 mW,针对小封装下的有限功耗做出优化,适合低功率电路。
  • 工作电压:50 V,适用于绝大多数低压电子系统。
  • 温度系数:±100 ppm/°C,保证温度变化下阻值稳定性满足一般应用需求。
  • 工作温度范围:-55 ℃ ~ +155 ℃,适用温度范围宽,能在工业级环境下长期工作。

三、应用场景

  • 消费电子:智能手机模组、穿戴设备、便携式音视频设备中的偏置与分压网络。
  • 通讯设备:射频前端的偏置电路(注意功率与噪声要求),模块化电源监测。
  • 工业控制:传感器接口、测量电路中对小功率精度电阻的替代与补充。
  • 测试与仪表:对尺寸和封装密度有要求,同时需要 ±1% 阻值精度的信号链元件。

四、电气与热性能说明

0402 尺寸的厚膜电阻因体积限制,额定功率相对较低(62.5 mW),在实际电路设计中需考虑功率分配和散热条件。环境温度升高时应按制造商的功率降额曲线(derating curve)进行设计,避免在高温环境下长期满负荷运行导致失效。TCR ±100 ppm/°C 在温度变化较大场合表现为阻值随温度变化可控,适合多数通用电路;如对温漂要求更严苛,请优先考虑低 TCR 或金属膜、薄膜产品。

五、可靠性与质量控制

UNI-ROYAL 厚声系列电阻通常经过包括但不限于下列可靠性试验:焊接热(符合 J-STD-020)、温度循环、湿热(HAST/85/85 或 IEC 湿热测试)、机械震动与冲击以及负载寿命测试等。生产过程中实施严格的阻值筛选与老化控制,确保长期稳定性与批次一致性。具体测试参数和认证请参见厂商详细数据手册或向供应商索取检测报告。

六、选型与使用建议

  • 请确认电路中的最大瞬态电压不超过 50 V,以免击穿或发热异常。
  • 考虑封装热阻与电路板散热条件,在高温或靠近大功率器件的位置应增加裕量或选用更高功率封装。
  • 对于对精度和温漂要求更高的场合,建议评估 ±0.1%~±0.5% 精度或更低 TCR 的替代品。
  • 在电源采样、精密测量等关键节点,应结合温度补偿与电路校准降低系统误差。

七、贴装与焊接注意事项

  • 推荐采用标准回流焊工艺(符合 JEDEC 回流规范),无铅回流峰值温度按 J-STD-020 要求控制,避免超出元件允许焊接热负荷。
  • 0402 小封装易受 PCB 焊盘设计影响,建议按照厂商推荐的焊盘尺寸与阻焊开窗比例进行版图设计,以保证焊接可靠性与回流后焊点良好。
  • 存储与搬运时避免潮湿、静电及机械冲击,贴片电阻易破碎,建议使用防静电包装并在回流前保持干燥状态。

八、包装与订购信息

该型号通常以带卷(tape & reel)形式供应,便于 SMT 自动贴装。订购时请确认包装单位(例如 3,000 或 10,000 颗/卷)、阻值批次号、需要的出厂测试单与可靠性报告。更多技术参数、尺寸图与推荐焊盘请参考 UNI-ROYAL 官方数据手册或向授权分销商咨询获取原厂资料。

如需我为该型号生成推荐 PCB 焊盘尺寸、回流焊曲线建议或与其它阻值/精度的比较选型表,可提供详细需求,我将进一步给出实用方案。

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
