Sunlord SDCL0603Q2N7ST02B03 贴片叠层电感产品概述

一、产品基本属性

Sunlord(顺络)SDCL0603Q2N7ST02B03是一款0201封装贴片叠层电感,针对高频小功率场景优化设计,核心参数清晰明确:

  • 标称电感值:2.7nH(纳亨)
  • 额定直流电流:500mA(毫安)
  • 直流电阻(DCR):200mΩ(毫欧)
  • 品质因数(Q值):[email protected](0.5吉赫兹)
  • 自谐振频率(SRF):10GHz(吉赫兹)
  • 封装规格:0201(英制尺寸,对应公制0603)
  • 工艺类型:叠层电感

型号编码可直观对应核心特性:“0603”为封装(公制),“2N7”表示2.7nH,“Q”关联高频Q值优化,“ST02B03”为顺络内部规格编码。

二、关键性能参数解析

1. 电感值与应用定位

2.7nH属于小容量高频电感,避免了大电感在GHz级频率下的寄生电容/电阻效应,是射频电路阻抗匹配、信号滤波的常用值,适配蓝牙、WiFi等主流通信频段。

2. 额定电流与直流损耗

  • 额定电流500mA:指电感工作时自身温升≤40℃的最大直流电流,实际应用需预留20%余量(建议≤400mA),防止过流导致性能衰减或失效。
  • DCR 200mΩ:反映直流电阻损耗,热损耗公式为(I^2 \times DCR),低DCR有助于降低小功率电路的电源损耗,提升效率。

3. 品质因数(Q值)与自谐振频率

  • Q值[email protected]:Q值是电感“损耗比”指标((Q=2πfL/R)),值越高表示对应频率下信号损耗越低。0.5GHz覆盖蓝牙、WiFi等通信子频段,此Q值满足射频匹配需求。
  • 自谐振频率10GHz:电感寄生电容与绕组谐振的频率,超过10GHz后电感呈容性,实际应用需将工作频率控制在10GHz以下,避免电路特性紊乱。

4. 封装与工艺特点

0201封装(尺寸≈0.6mm×0.3mm)是当前小型化设备的主流封装,可大幅节省PCB空间;叠层工艺通过多层陶瓷基片叠合绕组,结构紧凑、一致性好,抗机械应力能力强,适合批量生产与高可靠性场景。

三、典型应用场景

该电感的参数特性适配以下高频小功率场景:

  1. 高频通信终端:蓝牙(2.4GHz)、WiFi(2.4GHz/5GHz)、5G sub-6GHz频段的手机、智能穿戴(如无线耳机、智能手表),用于射频前端匹配、信号滤波。
  2. 便携式电子:USB-C接口EMI滤波、音频电路去耦,满足设备轻薄化需求。
  3. 物联网模块:无线传感器节点、IoT终端的信号链路匹配,提升抗干扰能力。
  4. 消费电子:智能音箱、无线充电器的高频部分,控制电磁干扰(EMI),符合EMC标准。

四、产品优势与注意事项

1. 核心优势

  • 小型化适配:0201封装满足高密度PCB布局,适配当前电子设备轻薄趋势。
  • 高频性能稳定:Q值[email protected]与自谐振10GHz,覆盖主流通信频段,信号完整性好。
  • 低损耗与可靠:叠层工艺一致性佳,DCR低,热损耗小,长期工作稳定性高。
  • 品牌保障:顺络作为电感龙头,产品符合RoHS环保标准,供应链成熟。

2. 应用注意事项

  • 频率限制:避免工作频率超过10GHz,防止电感容性化。
  • 焊接工艺:0201封装需高精度回流焊,避免虚焊、桥接。
  • 环境要求:存储/工作温度≤85℃、相对湿度≤90%,防止封装受潮。

五、总结

Sunlord SDCL0603Q2N7ST02B03是一款高频小功率贴片叠层电感,凭借小型化封装、优异高频Q值、低直流损耗等特点,广泛适配蓝牙、WiFi、5G等通信终端及便携式设备。其参数平衡性能与可靠性,是射频匹配、高频滤波的理想选择,需注意频率与电流限制以确保电路稳定。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
