PDPTAT0810-222K 产品概述
一、产品简介
PDPTAT0810-222K（品牌：PROD/谱罗德）是一款插件式工字电感，标称电感量为2.2mH，公差±10%，适用于中低频信号滤波与小电流电源去耦场合。外形为插件（D9.5 × L12mm），色环标识，便于目测识别和手工焊接装配。
二、主要参数
- 电感值：2.2 mH ±10%
- 额定电流：150 mA（持续通过而保持标准性能）
- 饱和电流（Isat）：300 mA（磁芯开始明显降感）
- 直流电阻（DCR）：约 3 Ω
- 类型：工字电感（插件、色环标识）
- 封装尺寸：直径约9.5 mm，长度约12 mm
三、电气特性与计算示例
- 直流损耗：P = I^2·DCR。按额定电流0.15 A计算，损耗约0.0675 W（67.5 mW）；在饱和电流0.3 A时损耗约0.27 W（270 mW）。
- 频率阻抗：XL = 2πfL（L=2.2 mH）。例如：
- f = 1 kHz 时 XL ≈ 13.8 Ω；
- f = 10 kHz 时 XL ≈ 138 Ω；
- f = 100 kHz 时 XL ≈ 1.38 kΩ。
由此可见，本器件在几十Hz以下以DCR为主，在kHz级及以上以感抗为主，对中高频干扰具有良好的抑制效果。
四、典型应用场景
- 开关电源与线性电源的输入/输出滤波（低电流、小功率）
- 模拟电路、音频系统的隔离和低频噪声抑制
- EMI/RFI 抑制回路、信号线去耦
- 作为滤波网络（LC、π 型滤波）中的感性元件
五、选型与使用建议
- 电流裕量：建议工作电流远低于饱和电流，通常取额定电流的70%以内以保证线性；若工作短脉冲接近300 mA，将出现电感下降。
- 温升与功耗：关注 DCR 引起的功耗及局部发热，长期使用时应评估散热条件。
- 容差影响：±10% 的公差会影响滤波截止频率，关键滤波设计应在实际测量后微调电阻/电容值。
- 焊接与机械：插件器件便于波峰或手工焊接，避免在靠近绕组处反复弯折引脚以防应力损伤。
六、总结
PDPTAT0810-222K 是一款体积小、便于装配的插件工字电感，适合中低频滤波与小电流电源去耦应用。选型时需综合考虑 DCR 导致的功耗、额定与饱和电流的裕量以及电感容差对系统性能的影响，以确保在目标应用中的稳定性与可靠性。若需进一步的频率响应曲线、温升或磁芯材料信息，可联系厂商获取详细测试数据。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
