WR06X393JTL 产品概述

一、产品简介

WR06X393JTL 是华新科(Walsin)出品的一款厚膜贴片电阻,0603 封装,标称阻值 39 kΩ,精度 ±5%,额定功率 100 mW。器件工作温度范围宽(-55 ℃ ~ +155 ℃),温度系数 TCR 标称 ±100 ppm/℃,适合一般电子产品中的通用分压、拉/下拉、滤波与偏置网络等场景。

二、主要参数

  • 电阻类型:厚膜电阻
  • 阻值:39 kΩ(393 表示)
  • 精度:±5%
  • 额定功率:100 mW(室温)
  • 额定工作电压:75 V
  • 温度系数:±100 ppm/℃
  • 工作温度:-55 ℃ ~ +155 ℃
  • 品牌:华新科(Walsin)
  • 封装:0603(英制,约 1.6 mm × 0.8 mm)

三、特性与优势

  • 通用性强:厚膜工艺成本低、批量一致性好,适用于消费类、工业及通信产品的常规电阻需求。
  • 温度稳定性中等:±100 ppm/℃ 属于常见的厚膜 TCR 等级,可满足多数非精密应用。举例:在 -55 ℃ 到 +155 ℃(ΔT = 210 ℃)范围内,理论阻值变化约为 2.1%。
  • 高温耐受:-55 ℃ ~ +155 ℃ 的工作温度适配多数恶劣环境应用。
  • 小尺寸:0603 适用于高密度 PCB 布局,节省空间。

四、典型应用

  • 拉/下拉电阻、偏置网络与电压分压器
  • 模拟信号通路的阻性元件(非精密测量)
  • 滤波/限流等常规电路
  • 消费电子、物联网终端、工业控制与通信设备中对体积和成本有要求的电阻应用

五、封装与焊接建议

  • 0603 封装体积小,焊盘设计应参考华新科推荐尺寸,确保焊接可靠性与良好可制造性。
  • 回流焊:请遵循厂商提供的回流曲线(常见制造流程峰值温度 ~245 ℃,具体以数据表为准)。
  • 焊接注意事项:避免在焊接过程中长时间高温加热,尽量减少温度循环次数,以防热应力造成损伤。

六、热与电气注意事项

  • 功率与电压关系:器件额定功率为 100 mW,因此在实际使用中应以功率限制为先。理论上在 39 kΩ 上使耗功 100 mW 时的最大安全电压约为 V = sqrt(P·R) ≈ 62.4 V;这低于器件标称的 75 V 额定工作电压。也就是说,当电阻值较高时,功耗限制可能比额定电压更先达到极限。
  • 功率降额:高温下需对功率进行降额处理(请参照华新科数据表的温度-功率降额曲线)。

七、可靠性与测试

  • 常见可靠性试验包括高温储存、负载寿命、温度循环、湿热与盐雾等,应按照应用重要性选择对应的验证项目。
  • 对于关键应用建议向供货方索取完整的可靠性报告与品质保证数据。

八、选型建议

  • 若设计对精度或温漂有较高要求,建议选用更高精度(如 ±1% 或 ±0.1%)或更低 TCR 的薄膜/金属膜电阻或采用多点温度补偿设计。
  • 在高电压或高温场合,务必核查功率降额曲线与最大允许电压,必要时增加阻值或更换更大功率/更高电压等级的器件。
  • 对于批量采购,建议先索取样品并在目标 PCB 与工艺条件下进行实测验证。

总结:WR06X393JTL 为一款性价比高、适用于通用场景的 0603 厚膜电阻,适合对体积与成本有要求且对精度与温漂要求不高的电子产品。选型时应关注功率与温度的降额特性,并按华新科数据表进行焊接与可靠性验证。

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
