201007J039JT4E 产品概述

一、产品简介

201007J039JT4E 是由 UniOhm(台湾厚声)出品的一款高可靠性片式厚膜电阻,封装为 2010(公制 2.0 × 1.25 mm,常见对应英制 0805)。该型号阻值 3.9Ω,精度 ±5%(J),额定功率 0.75W(3/4W),额定工作电压 200V,温度系数(TCR)±200ppm/℃,工作温度范围为 -55℃ 至 +155℃,适用于对功耗、耐压及热稳定性有中等要求的应用场合。

二、主要参数

  • 电阻类型:厚膜电阻(片式)
  • 阻值:3.9Ω
  • 精度:±5%(J)
  • 额定功率:750mW(在额定环境及散热条件下)
  • 额定工作电压:200V
  • 温度系数:±200ppm/℃(典型)
  • 工作温度:-55℃ ~ +155℃
  • 封装:2010(尺寸约 2.0 × 1.25 mm)
  • 品牌:UniOhm(台湾 厚声)

三、性能特点

  • 稳定性良好:厚膜工艺使其在一般环境下具有可靠的电阻稳定性与一致性,适合批量生产和自动贴装。
  • 耐热与耐压:高温工作上限达 +155℃,额定工作电压 200V,可应对中等电压及瞬态应力。
  • 热阻与散热:2010 封装在 3/4W 等级中热容量较好,但在高功耗工作下需合理 PCB 散热设计以避免过热。
  • 成本效益高:厚膜 5% 精度适合成本敏感且对高精度要求不高的电路设计。

四、典型应用场景

  • 开关电源与功率管理中的分流、电流限制或阻尼
  • LED 驱动、降压保护电阻
  • 工业控制与仪表中对中低精度电阻的场合
  • 汽车电子(非关键传感器)及消费电子的电源路径与热耗分散

五、安装与使用建议

  • 推荐采用回流焊工艺,遵循元器件及焊料厂商的回流曲线以保证焊接可靠性。
  • 在高功耗应用中应增加周围铜箔面积或设置散热铜层/热沉,通过热扩散降低芯片温升。
  • 对于连续高温环境或近极限功率使用,建议参考厂方降额曲线进行功率与温度匹配,或采用并联/并组分担功耗。
  • 存储时避免潮湿与腐蚀性气体,贴片卷盘尽量在湿度控制环境中保管与使用。

六、可靠性与品质保证

UniOhm 厚声采用成熟厚膜制程并通过常规的热循环、湿热及焊接可靠性测试,适合大批量工业制造使用。对于关键或特殊环境应用,建议向供应商索取具体的可靠性报告与测试数据以便评估。

七、选型与替代建议

若需更高精度或更低 TCR,可考虑薄膜或低温漂厚膜产品(如 ±1% 或 ±50ppm/℃ 等级);若单元功耗需求高于 0.75W,建议选用更大封装(1206/2010 以上功率等级更高的型号或功率电阻)。

八、常见注意事项

  • 不建议长期在额定温度上限持续运行,需预留安全余量并做好散热设计。
  • 在高脉冲或冲击电压环境下需评估击穿与老化风险,必要时增加保护元件(如限流或吸收元件)。
  • 订购时确认包装形式(卷带/盘/散装)与管脚方向以便贴片机编程与生产对接。

如需详细的降额曲线、焊接参数或可靠性测试报告,可联系供应商索取 Datasheet 与相关认证文件。

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
