0402WGF332JTCE 产品概述

一、规格概述

0402WGF332JTCE 为 UNI-ROYAL(厚声)品牌的贴片厚膜电阻,封装尺寸为 0402(约 1.0 mm × 0.5 mm)。标称阻值 33.2 Ω,阻值精度 ±1%,额定功率 62.5 mW(常温额定值),额定工作电压 50 V,温度系数(TCR)±200 ppm/℃,工作温度范围 -55 ℃ 至 +155 ℃。该器件适用于空间受限、低功耗的电路设计,常见于移动设备、消费电子、测量仪器和各类信号调理电路。

二、主要特性

  • 厚膜工艺,性能稳定、成本可控。
  • 小型 0402 封装,适合高密度 PCB 布局与自动贴装。
  • ±1% 精度,满足对阻值较高要求的精密分压、阻抗匹配场合。
  • TCR ±200 ppm/℃,在宽温范围内阻值漂移可控,利于温度补偿设计。
  • 工作温度 -55 ℃ ~ +155 ℃,耐环境能力强。

三、电气性能要点

  • 阻值:33.2 Ω(±1%)。
  • 额定功率:62.5 mW(通常为在 +70 ℃ 时的额定功率)。设计时建议留有裕量,避免长期在额定功率下持续工作。
  • 最大工作电压:50 V;应确保电路中施加在该电阻上的电压不超过此值,以免发生击穿或绝缘退化。
  • 温度系数 ±200 ppm/℃ 表示随环境温度变化,阻值会有线性漂移,设计时可据此估算温度引起的误差。

四、热特性与功率降额

在高温环境下需对额定功率进行降额管理。通常以 +70 ℃ 为基准额定点,超过该温度应线性降额至最高工作温度 +155 ℃ 时为 0 mW。降额计算示例(线性模型): P_allowed = 62.5 mW × (1 - (T - 70) / (155 - 70)) 例如在 +125 ℃ 时,允许功率约为 22 mW(近似值)。实际系统应采用更保守的裕量以提高可靠性。

五、封装与机械特性

0402 封装适用于 0402 标准 PCB 焊盘布局(公差依应用与工艺而定)。该尺寸对贴装、焊膏量和回流曲线较敏感,需控制焊膏体积以避免 tombstone 现象或焊接不良。组件耐震动、耐温冲击性能良好,适合常规电子制造工艺。

六、焊接与安装建议

  • 推荐采用回流焊工艺,遵循元件厂及板厂的回流曲线(典型无铅峰值温度 ≤ 260 ℃)。
  • 控制焊膏体积与焊盘尺寸,避免过多焊膏导致浮贴或短路。
  • 使用自动贴片机进行贴装,吸嘴选择要适配 0402 小体积器件。
  • 焊后如需清洗,应选择对厚膜电阻和保护涂层安全的清洗剂,并充分干燥。

七、典型应用场景

  • 精密分压与基准电路中的阻值元件。
  • 滤波、阻抗匹配和信号衰减网络。
  • 低功耗传感与测量前端(非大功率能耗场合)。
  • 移动终端、消费电子、小型工业控制器件中常用的通用电阻元件。

八、可靠性与质量保证

UNI-ROYAL 产品通常经过焊接可靠性、湿热、温度循环及寿命测试等一系列可靠性验证。建议在关键应用中参考厂方完整的可靠性测试报告,并按 IPC/JEDEC 等行业规范进行样件验证。

九、采购与存储

  • 型号:0402WGF332JTCE;请在采购时确认批次与检测报告以保证一致性。
  • 包装:常见为卷带 Reel,便于 SMT 自动化生产。
  • 存储:建议存放于干燥环境,避免潮湿与长时间阳光直射;在再流焊前如遇长时间暴露,可进行烘烤除湿处理。

如需进一步的电气特性曲线、回流曲线建议或可靠性测试数据(如温度循环、负载寿命曲线),可提供具体应用场景与测试条件,以便给出更精确的工程级建议。

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
