PDPTAT0810-470M 产品概述
一、产品简介
PDPTAT0810-470M 是谱罗德（PROD）推出的一款径向插件工字电感（色环标示），标称电感量 47 μH，公差 ±20%。封装尺寸约 8×10 mm，线径 0.6 mm，适用于中低频功率滤波与阻断噪声的应用场景。外形为径向引线，便于通孔插件（THT）装配与手工波峰/回流焊接（注意工艺温度）。
二、主要技术参数
- 电感值：47 μH，公差 ±20%
- 额定电流（Ith）：2.3 A（热稳定允许连续电流）
- 饱和电流（Isat）：1.7 A（接近该电流时电感量显著下降）
- 直流电阻（DCR）：73 mΩ
- 线径：0.6 mm；封装：径向引线，8×10 mm；安装形式：插件（THT）
- 标记：色环/色码；品牌：PROD（谱罗德）
说明：额定电流与饱和电流含义不同——额定电流用于热升限考量（温升允许范围内的连续电流），饱和电流是磁芯趋于饱和导致有效电感下降的电流阈值。设计时需同时兼顾两者。
三、典型电性能与估算
- 在额定电流 2.3 A 下的铜损约为 P = I^2·DCR ≈ 2.3^2×0.073 ≈ 0.39 W。
- 在饱和电流 1.7 A 时损耗约 0.21 W。
因此在高占空比或连续流大电流场合需注意散热与功耗管理；若电路对感值稳定性敏感，工作电流建议控制在 Isat 以下，避免电感量下降影响滤波性能。
四、主要应用场景
- 开关电源（DC-DC 降压、升压）输入/输出滤波电感
- 电源滤波与去耦、低频 EMI 抑制
- 充电设备、适配器、家电等中低功率电源模块
- 信号线前端的低频共模/差模滤波（视电路设计而定）
五、安装与使用注意
- 裸线径 0.6 mm，建议 PCB 孔径 0.9–1.1 mm，确保焊接可靠，避免机械应力。
- 波峰或热风焊接时注意最大引脚温度与时间，避免绝缘漆或色环损伤。
- 若需保持标称电感，应将连续电流控制在 Isat（1.7 A）以下；若只关注温升，则不得超过额定电流 2.3 A。
- 长期高温环境会加速磁芯特性变化，设计时预留温度余量并做好散热或通风。
六、选型建议与替代方案
- 若需更低 DCR 或更高饱和电流，应选用体积更大或使用更粗导线/更低损耗磁芯的型号。
- 对电感公差、温漂或 高频特性有严格要求的场合，考虑金属磁芯或贴片功率电感替代，并关注规格手册中的 L–I 曲线与频率响应。
七、包装与存储
- 建议干燥、常温保存，避免潮湿与强光直射；运输与存放过程中防止挤压变形。
PDPTAT0810-470M 以其小巧的径向封装与较高的额定电流，适用于通孔中低功率开关电源和滤波场合。设计时需在热、磁饱和与损耗三者之间权衡，确保电路长期稳定运行。若需更详细的 L(I)、频率特性或应用电路建议，可提供具体工作条件以便给出精确匹配方案。

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.
