PDSQAT1212-103MWB 产品概述

PDSQAT1212-103MWB 为谱罗德(PROD)推出的双通道高压插件电感器,面向需在高电压、高抑制需求下工作的电源滤波与干扰抑制场景。器件在1 kHz 测试条件下标称电感量为10 mH,兼顾较大感量与高电压耐受能力,适用于工业电源、隔离供电与高压信号链的滤波与能量储存。

一、主要参数

  • 通道数:2(双通道设计,可用于双线滤波或差/共模组合)
  • 标称电感:10 mH @ 1 kHz
  • 额定电流:2.5 A(连续)
  • 直流电阻(DCR):120 mΩ
  • 额定耐压:1 kV(DC/AC 均标称)
  • 绝缘电阻:≥100 MΩ
  • 工作温度:-40 ℃ ~ +105 ℃
  • 封装形式:插件(Through-hole)
  • 品牌:PROD(谱罗德)

二、主要特性

  • 高电压耐受:1 kV 级耐压与高绝缘电阻,便于在高电压隔离或测量链路中使用。
  • 双通道灵活性:可独立用于两路信号或按差模/共模配置实现更高效的干扰抑制。
  • 较大感量:10 mH 在低频滤波和能量缓冲方面表现优异,有利于降低开关噪声与纹波。
  • 可靠的温度范围:-40~+105 ℃ 覆盖大多数工业环境。

三、典型应用场景

  • 工业电源滤波与EMI抑制(高压侧或隔离侧)
  • 仪器仪表高压测量通道的输入滤波
  • 直流-直流变换器的输入/输出滤波与储能元件
  • 医疗、通信等需高绝缘或高抗干扰能力的系统(需按相关安全标准验证)

四、电气性能与工程注意事项

  • 在额定电流 2.5 A 条件下,近似铜损 P = I^2·DCR ≈ 0.75 W,设计散热与热箝位时应考虑该功耗。
  • 标称电感为 10 mH(1 kHz),若在不同频率或大电流下使用,实际感量可能因磁芯饱和和频率特性发生变化,建议在目标工况下做测量验证。
  • 高频噪声抑制能力与绕组构造、寄生电容相关,如需处理高频干扰可结合适当的旁路电容形成 RC/LC 复合滤波网络。
  • 对于 1 kV 级别应用,应确保器件周边满足爬电距离和气隙要求,正确设计 PCB 与机械间隔以保证安全可靠。

五、封装与安装

  • 插件封装便于手工焊接与波峰/回流兼容的组装流程,适合小批量或维修替换场景。
  • 安装时注意保持绕组及引脚绝缘完整,避免机械应力传递到线圈。

六、可靠性与测试建议

  • 建议在最终产品中进行温升测试与长期老化试验,验证在额定电流与环境温度下的寿命与稳定性。
  • 高压应用中应进行耐压、绝缘电阻和介质击穿相关测试,确保满足系统安全规范。

七、选型与注意事项

  • 若系统工作电流高于2.5 A,应选用更大额定电流或并联使用并综合评估均流与温升。
  • 对于需要严格共模抑制的应用,确认双通道结构的耦合方式是否满足设计需求(独立绕组或有磁耦合)。
  • 采购时注明完整型号 PDSQAT1212-103MWB,并确认批次测试报告以确保电感量与绝缘特性一致。

凭借高感量、高电压耐受与双通道设计,PDSQAT1212-103MWB 适合在对抗低频噪声、要求高绝缘等级的工业与特殊电源系统中作为可靠的滤波与能量元件。若需进一步的波形测试数据、尺寸图或样品评估建议联系谱罗德技术支持获取详细资料。

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
