PDSH0512I-221K 产品概述

PDSH0512I-221K 是谱罗德(PROD)推出的一款色环式插件电感,外形小巧、结构可靠,适用于低频滤波与电源去耦等场景。器件标称电感值为 220 μH(公差 ±10%),额定电流与饱和电流均为 420 mA,直流电阻 DCR 为 1.2 Ω,典型外形尺寸为直径 5 mm × 长度 12.5 mm(D5×L12.5mm),插件式封装(5×12 mm),便于手工焊接与波峰/回流插件工艺。

一、主要规格要点

  • 型号:PDSH0512I-221K
  • 品牌:PROD(谱罗德)
  • 电感值:220 μH,公差 ±10%
  • 额定电流(Ir):420 mA
  • 饱和电流(Isat):420 mA
  • 直流电阻(DCR):1.2 Ω
  • 封装与外形:插件/色环式,D5 × L12.5 mm(实物尺寸约 5×12.5 mm)
  • 应用方式:通孔插件,适配手工或自动插件焊接流程

二、电性能说明与设计参考

  • 电感值 220 μH,适合用于较低频率区域的滤波与能量存储,能有效抑制几百 Hz 至几十 kHz 的干扰成分。
  • 额定电流与饱和电流均为 420 mA,意味着在接近或超过 420 mA 时电感可能发生显著磁饱和,电感量会下降,应在系统设计中留有裕量。建议实际工作电流按 60%–80% 的额定电流进行选型以保证稳定性与温升控制。
  • 直流电阻 1.2 Ω,按额定电流计算的铜耗近似为 P = I^2·R ≈ 0.42^2 × 1.2 ≈ 0.21 W;在连续工作场景下需关注器件温升与周围散热条件。DCR 偏高意味着在大电流或需低损耗场合应考虑更低 DCR 的替代型号。

三、典型应用场景

  • 开关电源、稳压模块的输入/输出滤波与纹波抑制(中低功率场合)。
  • 模拟/数字混合电路的电源去耦,抑制电源线上的低频干扰。
  • 工业控制、仪表、仪器板上作为通用滤波元件使用。
  • 家电与消费电子中小电流滤波需求的替代或补充元件。

四、安装与使用建议

  • 焊接:插件式设计适合波峰焊或手工焊接。建议遵循厂家焊接温度与时长规范(常见做法:峰值温度勿超过推荐值,波峰焊/手工焊接时间尽量控制在较短时间以防漆包线或磁芯受损)。
  • 热管理:由于 DCR 导致的功耗约 0.21 W(在 420 mA 下),长期大电流工作时需考虑 PCB 散热、器件间距与通风。
  • 电流裕量:为避免磁饱和与电感下降,设计时建议采用额定电流的 60%–80% 作为持续工作电流参考。若系统存在冲击电流或瞬态较大,应选择额定电流更高的型号。
  • 环境与可靠性:避免在强腐蚀性气体、高湿或极端高温环境中长期无保护使用;如需特殊环境适应性,请向生产厂家索要详细环境与老化数据。

五、选型与替代建议

  • 若系统要求更低 DCR 或更高持续电流,应选择同类电感中标称电流更高、铜径更粗或更大体积的型号。
  • 对于高频滤波或对电感值波动敏感的场合,可考虑贴片电感或多匝精密绕线电感以获得更稳定的频率特性。
  • 在替换或并联使用时,注意磁耦合与互感影响,避免将多个色环电感紧密并排造成性能异常。

总结:PDSH0512I-221K(220 μH, 420 mA)是一款适合中小电流低频滤波与去耦的色环插件电感,结构简单、易于装配。其相对较高的 DCR 要求在设计时关注功耗与温升,并为持续工作电流留足裕量。有关更详细的电气特性曲线、温升测试与焊接规范,请向谱罗德索取完整数据手册以作最终设计确认。

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.
