顺络SDCL0603Q7N5HT02B03 贴片电感产品概述

一、产品基本信息

SDCL0603Q7N5HT02B03是顺络电子(Sunlord)针对高频射频场景推出的一款小型化贴片电感,采用0201英制封装(对应公制0603),核心定位为低功耗、高精度的射频电路匹配/滤波元件,适配物联网、无线通信等领域的小型化设备需求。

二、核心性能参数解析

1. 电感值与精度

标称电感值为7.5nH,精度±3%,属于射频电路常用的小电感范畴。±3%的高精度可减少电路调试难度,满足蓝牙、WiFi等模块对电感参数一致性的要求,避免因电感偏差导致信号匹配异常。

2. 额定电流与直流电阻(DCR)

  • 额定电流:300mA(连续工作电流上限,温度上升≤40℃);
  • 直流电阻:500mΩ(极低损耗)。
    在300mA工作电流下,直流损耗仅约0.045W(I²R计算),可有效降低设备功耗与散热压力,适配智能穿戴、传感器等低功耗场景。

3. 品质因数(Q值)

在500MHz频率下Q值为13,Q值是电感储能与损耗的比值,越高表示高频损耗越低。该参数确保产品在2.4GHz蓝牙、5GHz WiFi等主流频段内,信号传输效率更高,衰减更小。

4. 自谐振频率(SRF)

自谐振频率为4.7GHz,即电感在该频率下因寄生电容与电感谐振,表现为纯电阻特性。4.7GHz的SRF覆盖了多数无线通信频段(2.4~5GHz),避免谐振导致的性能失效,保障高频应用稳定性。

三、封装与工艺优势

1. 0201小型化封装

尺寸约0.6mm×0.3mm,体积仅为传统0402封装的1/4,可显著节省PCB空间,适配智能手机、智能手表等高密度布局的小型设备。

2. 顺络薄膜电感工艺

  • 高温兼容性:可耐受260℃回流焊温度,焊接可靠性强;
  • 低寄生参数:寄生电容/电阻控制在nF/pF、mΩ级,进一步优化高频性能;
  • 批量一致性:薄膜工艺确保批量产品参数偏差极小,适合大规模自动化生产。

四、典型应用场景

该产品的参数特性使其广泛应用于以下高频场景:

  1. 无线通信模块:蓝牙(BLE)、WiFi(2.4/5GHz)、ZigBee模块的信号匹配、滤波电路;
  2. 物联网终端:智能传感器、智能家居设备的射频前端电路;
  3. 小型消费电子:智能手机、智能手表的无线充电辅助电路、射频信号处理单元;
  4. 射频测试设备:小型信号发生器、频谱分析仪的匹配网络。

五、使用注意事项

  1. 焊接规范:回流焊温度≤260℃(持续时间≤10秒),避免过高温度损坏电感;
  2. 电流降额:实际工作电流建议不超过额定电流的80%(240mA),延长产品寿命;
  3. 存储条件:未焊接产品需存储在-40℃~85℃、湿度≤60%的环境中,避免受潮;
  4. PCB布局:电感附近避免布置大功率元件或高噪声电路,减少电磁干扰。

该产品通过优化高频性能与小型化设计,可有效提升射频电路的信号质量与设备集成度,是物联网、无线通信领域的高性价比选择。

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.

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
