MPL1608S1R0MHT 产品概述
一、主要参数
- 型号：MPL1608S1R0MHT（顺络 Sunlord）
- 封装：0603（1608公制）
- 类型：叠层贴片电感（Multilayer Chip Inductor）
- 标称电感：1.0 μH
- 公差：±20%
- 额定电流：950 mA
- 直流电阻（DCR）：200 mΩ
- 自谐振频率（SRF）：约 75 MHz
- 封装及包装：SMT 贴片，常见带卷包装，符合 RoHS 要求（详见厂方资料）
二、产品特点
- 体积小、适合集成：0603 封装适合高密度贴片设计，适用于便携式与空间受限的电路板。
- 通用功率滤波：1 μH ±20% 属于通用型感值，适配常见电源滤波与去耦场景。
- 中等直流损耗：200 mΩ 的 DCR 在接近额定电流下会产生一定的功耗（见下），需考虑热管理与电流余量。
- 高频特性：SRF ≈ 75 MHz，器件在此频率附近开始出现寄生电容影响，适用于 MHz 级以下的电源与 EMI 滤波应用。
三、性能参考与计算
- 交流阻抗参考：XL = 2πfL
- f = 1 MHz 时 XL ≈ 6.28 Ω
- f = 10 MHz 时 XL ≈ 62.8 Ω
- 直流功耗（在额定电流）：
- P = I^2·R = (0.95 A)^2 × 0.2 Ω ≈ 0.18 W（约 180 mW），说明在长时间高负载下会有显著发热，应做电流余量或散热管理。
- 频率使用建议：感性工作区间在 SRF 低于 75 MHz 时有效，若在高频段使用需评估寄生电容影响及阻抗曲线。
四、应用场景
- DC-DC 降压/升压转换器的输入/输出滤波与去耦
- 电源线与信号线的 EMI 抑制
- 模拟前端或基带电路的低频滤波
- 便携设备、通信终端、电源管理模块等空间受限场合
五、PCB 布局与焊接建议
- 焊盘尺寸与焊膏量请参考顺络推荐的 0603 贴片封装 land pattern，以保证焊接可靠性与热传导。
- 尽量使电感与被滤波器件（如电容、芯片）距离最短，以减小环路面积和寄生感抗。
- 焊接工艺遵循厂方推荐回流曲线（参考 J-STD-020），避免超温或反复回流导致性能漂移。
- 高电流场合建议增加铜箔厚度或加大过孔以改进散热。
六、选型与使用注意
- 若需更低温升或更高稳定电感，建议选用 DCR 更低或额定电流更高的产品，或选择更大封装型号。
- 长期连续工作应考虑 70% 左右的电流去率（即持续电流建议低于额定值的 60–80%），以延长寿命并保持电感特性。
- 在关键射频或高频滤波场合，应参考厂方的阻抗/频率曲线及 S 参数以确认性能符合要求。

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.
