PDPTAT0810-471K — 470µH 工字插件电感（谱罗德 PROD）
一、产品简介
PDPTAT0810-471K 为谱罗德（PROD）推出的径向插件工字电感，标称电感值 470µH，精度 ±10%。外形采用色环标识，便于目视识别，适用于通用电源滤波、磁环退耦及中低频抑噪场合。体积小、结构稳固，便于手工或波峰/回流焊接安装。
二、主要电气参数
- 电感值：470µH ±10%
- 额定直流电流（Ir）：400mA（持续工作电流建议按额定值适度降额）
- 饱和电流（Isat）：1A（在该直流偏置下电感显著下降）
- 直流电阻（DCR）：约 700mΩ（典型值，测量温度 20°C）
- 类型：工字（插件/径向引线）
- 标记/封装：色环，插件式（参考外形 D9.5×L12 mm，封装参考 8×10 mm）
三、典型应用场景
- DC 电源滤波、输入/输出端的低频噪声抑制
- 开关电源的外围滤波与整流后滤波
- 模拟电路、传感器供电滤波与去耦
- EMI 抑制线圈、信号链低频隔离
四、选型与使用建议
- 电流降额：长期工作时建议将工作电流控制在额定电流以下（典型建议 70%~85% 的额定值），以降低温升并延长寿命。
- 饱和注意：在近饱和电流时电感值会急剧下降，应避免在工作点频繁接近或超过 Isat。
- DCR 与功耗：700mΩ 的 DCR 会产生一定的功耗（P = I^2·R），高频或大电流场合需评估温升与效率影响。
- 测试条件：建议在 1kHz/10kHz 常规测试频率下测量电感值，并在不同直流偏置下验证饱和特性。
五、机械与焊接注意
- 外形约 Φ9.5×12 mm，径向引线，建议 PCB 孔径 φ0.8~1.0 mm；安装时注意引脚成型避免裂纹或应力集中。
- 支持手工焊接与波峰焊；建议遵循无铅焊接工艺规范，控制焊接温度与时间以防绕组绝缘损伤（详见厂方焊接说明）。
- 存储运输应防潮、防挤压，避免长期强烈振动导致引线松动或绕组移位。
六、质量与测试建议
- 出厂前建议进行电感值、DCR、绝缘电阻和直流偏置下的 L-Id 测试；对批量使用建议抽样作温升及寿命测试（加速老化）。
- 对于对 EMI/EMC 有严格要求的系统，建议配合阻容滤波网络进行整体设计与验证。
七、优势总结
PDPTAT0810-471K 兼具中等电感值与紧凑封装，适合中低频滤波与电源去耦应用。额定 400mA 与 1A 饱和电流提供良好的动态范围，色环标识和插件形式利于快速识别与安装，是通用电子产品和电源模块中常用的可靠选择。若需更详细的机械图纸、温升曲线或典型应用电路，请联系供应商索取完整数据手册。

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.
