SDCL0603QR10JT02B03贴片电感产品概述

一、产品基本属性

该产品为顺络电子(Sunlord) 推出的高频小电流贴片电感,核心属性如下:

  • 封装规格:0201(英制封装,对应公制尺寸0.6mm×0.3mm),是当前主流最小贴片电感封装之一,适配高密度PCB设计;
  • 料号解析:SDCL0603QR10JT02B03中,0603对应公制封装标识,R10J表示100nH标称电感值+±5%精度(R代小数点,J为精度代码),T02B03为顺络内部工艺及批次编码;
  • 品牌背景:顺络电子是国内电感行业龙头,专注被动元件研发20余年,产品覆盖消费电子、通信、汽车等领域,可靠性经行业验证。

二、核心电性能参数解析

产品参数针对高频小电流射频场景优化,关键指标如下:

1. 电感值与精度

标称电感值100nH,精度±5%,满足商用射频电路对电感一致性的基本要求——无需额外校准即可稳定匹配电路阻抗,避免因电感偏差导致信号反射。

2. 额定电流

连续工作电流80mA,是电感不发生磁饱和、性能无明显衰减的最大电流。实际应用建议降额20%-30%(即≤64mA),避免长期过热导致寿命下降(顺络测试数据显示,超额定电流20%工作1000小时,电感值漂移≤1%)。

3. 直流电阻(DCR)

4Ω,为电感线圈的直流内阻。小电流场景下(≤80mA)功耗仅为I²R=0.0256W,对电源效率影响极小,适合便携设备的低功耗需求。

4. 品质因数(Q值)

300MHz下Q值为10,Q值公式为Q=2πfL/R(f为频率,L为电感值,R为串联等效电阻),该参数表明在300MHz频率点损耗较低,适合Sub-1GHz频段(300MHz-900MHz)射频电路。

5. 自谐振频率(SRF)

1GHz,当工作频率超过SRF时,电感会因寄生电容与电感的谐振效应呈容性,因此产品最佳应用频段为**≤800MHz**(留20%余量避免性能突变)。

三、典型应用场景

该产品因小封装、高频低损耗特性,主要适用于以下场景:

1. Sub-1GHz无线通信模块

如915MHz LoRa物联网终端、433MHz遥控设备、蓝牙低功耗(BLE)模块的匹配网络,匹配电路谐振点需求,抑制信号干扰。

2. 小型射频前端电路

FM收音机的中频滤波电路、智能手表的蓝牙天线匹配电路,利用其高频低损耗特性提升信号传输效率。

3. 便携设备电源滤波

智能手机、智能手环等设备的小电流电源回路滤波,过滤高频噪声(如开关电源纹波),保障传感器、通信模块稳定工作。

4. 消费电子传感器电路

心率传感器、环境光传感器的信号调理电路,过滤杂波干扰,提升传感器数据准确性。

四、产品选型优势

  1. 高密度适配:0201封装大幅节省PCB空间,与主流SMT生产线兼容,适合便携设备的小型化设计;
  2. 高频性能稳定:300MHz下Q值10,在Sub-1GHz频段内损耗可控,满足射频电路对信号完整性的要求;
  3. 可靠性与一致性:顺络采用自主研发的磁芯材料(低损耗铁氧体)和绕线工艺,产品批次一致性好,长期工作MTBF≥10万小时;
  4. 成本效益平衡:±5%精度覆盖多数商用场景,无需高精度电感的额外成本,性价比突出。

五、使用与存储注意事项

  1. 焊接工艺:建议回流焊,峰值温度控制在235±5℃,焊接时间≤30秒;禁止手工焊接(易损伤磁芯);
  2. 电流限制:实际工作电流需低于80mA,长期超电流会导致电感饱和、DCR上升甚至失效;
  3. 频率限制:禁止在≥1GHz电路中使用,否则电感呈容性,影响电路功能;
  4. 存储环境:未开封产品存储于-40℃~85℃、湿度≤60%环境;开封后建议1个月内使用,避免引脚氧化。

该产品是顺络针对高频小电流场景的经典型号,参数匹配性强,可稳定支撑多数商用射频与便携设备的需求。

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.

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
