MCL1608S4R7MT 产品概述
一、产品简介
MCL1608S4R7MT（顺络 Sunlord）是一款0603（1608公制）尺寸的叠层贴片电感，标称电感值为4.7μH，公差±20%。该器件面向体积受限、低功率的电源与滤波应用，额定直流电流为100mA，直流电阻（DCR）为780mΩ，自谐振频率（SRF）约为35MHz。
二、主要电气参数
- 电感值：4.7μH ±20%
- 额定电流：100mA（请按额定值选型并考虑裕量）
- 直流电阻（DCR）：0.78Ω（影响功耗与温升）
- 自谐振频率：≈35MHz（高于该频率器件呈容性行为）
- 封装：0603（1.6mm × 0.8mm）叠层结构
三、特性与优势
- 小尺寸、低剖面，适合紧凑PCB布局与便携设备应用。
- 叠层陶瓷结构实现良好的频率响应与可靠性。
- 适用于低电流旁路、滤波以及阻断高频干扰场景。
- 自谐振频率较高，适合工作在数十兆赫以下的滤波/去耦场合。
四、典型应用
- 电源输入滤波（LC/π滤波器）与去耦电路
- EMI/RFI抑制与共模/差模滤波（配合电容使用）
- 小功率DC-DC转换器的输出滤波（注意电流裕量）
- 模拟及数字电路的信号链隔离与噪声抑制
五、选型与注意事项
- DC偏置效应：在施加直流电流或外加磁场时，实际电感会下降，应参考厂家偏置曲线并预留裕量。
- 温升与功耗：DCR为780mΩ，按P=I^2·R计算，在接近额定电流时产生的功耗与温升需考虑。
- 频率工作范围：在接近或超过SRF（≈35MHz）时，器件不再表现为纯感性，应避免把工作频率设置在SRF附近。
- 环境与焊接：支持常规回流焊工艺，推荐遵循制造商的回流曲线与PCB焊盘设计，避免长时间过热影响可靠性。
六、PCB布局与焊接建议
- 焊盘设计应与厂商推荐的Land Pattern一致，保证良好焊接填充与机械强度。
- 若用于滤波输入，尽量将电感靠近噪声源或连接点放置，缩短敏感回路的走线。
- 对于高频抑制，电感与旁路电容之间走线应尽可能短，降低寄生电感与串联电阻带来的影响。
七、小结
MCL1608S4R7MT是一款面向低电流、小尺寸应用的叠层贴片电感，适用于滤波、去耦和EMI抑制等场景。选型时重点关注电流额定、DCR影响及自谐振频率带来的限制，结合实际电路的直流偏置和频谱分布进行合理匹配，可在空间受限的设计中发挥良好效果。若需更详细的偏置曲线、温度系数或可靠性数据，建议查阅顺络官方数据手册或联系供应商获取完整规格书。

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.
