顺络SDCL0603QR12JT02B03贴片电感产品概述

顺络SDCL0603QR12JT02B03是一款针对高频小型化电路设计的0201(英制)/0603(公制)封装贴片电感,凭借精准的电性能、稳定的损耗特性及紧凑的体积,适配ISM频段无线通信、蓝牙模块等场景的射频匹配需求。

一、产品封装与定位

该电感采用0201英制贴片封装(公制尺寸0.6mm×0.3mm),体积仅为传统插件电感的1/5左右,可满足高密度贴装设计要求,有效降低终端产品的空间占用。封装结构为顺络成熟的陶瓷基绕线工艺,兼具耐温性(支持260℃回流焊)与机械强度,且符合RoHS 2.0、REACH等环保指令,无铅无卤,适配全球市场合规需求。

二、核心电性能参数

2.1 电感值与精度

电感标称值为120nH,精度控制在**±5%** 范围内,属于高频电感领域的可靠精度等级。该精度可避免因电感偏差导致的射频信号频率偏移,确保电路匹配一致性,适配对电感值稳定性要求较高的射频前端设计。

2.2 电流与损耗特性

  • 额定直流电流(Irms):80mA:为持续工作时的最大允许电流,此时电感自身温度上升控制在顺络标准的40℃以内(环境温度25℃下),可保障长期工作无热失效风险;
  • 直流电阻(DCR):5Ω:反映电感线损的关键指标,该值在0201封装的120nH电感中处于合理区间,既平衡了电感量与损耗,又适配小电流场景的能效需求。

三、高频特性:Q值与自谐振频率

3.1 品质因数(Q值)

Q值为9@300MHz,是衡量电感储能与损耗比的核心指标。300MHz为ISM频段(315MHz、433MHz)的临近频率,该Q值可有效降低电感在高频下的能量损耗,提升射频信号的传输效率,减少信号失真与杂散干扰。

3.2 自谐振频率(SRF)

自谐振频率为1GHz,即电感与自身寄生电容谐振的频率点。当工作频率低于1GHz时,电感呈现感性特性;超过1GHz则转为容性。实际应用中需确保工作频率远低于1GHz(如300MHz以内),以维持电感的感性功能稳定,避免特性突变影响电路性能。

四、典型应用场景

SDCL0603QR12JT02B03针对高频小电流电路优化,典型应用包括:

  1. ISM频段无线通信:315MHz/433MHz无线遥控器、无线传感器节点、智能家居控制模块;
  2. 蓝牙低功耗(BLE)链路:1GHz以下的BLE通信模块(如早期BLE 4.0版本的射频匹配);
  3. 小型射频前端:手机/智能穿戴的900MHz频段(GSM)射频匹配电路、TWS耳机的无线子系统;
  4. 工业物联网终端:低功耗无线传感器的射频发射/接收电路。

五、顺络品牌可靠性优势

顺络作为国内电感制造龙头,该系列电感具备以下可靠性保障:

  • 工艺一致性:采用高精度绕线与激光微调工艺,批量产品的电感值、DCR偏差控制在规格范围内(电感值偏差≤±5%,DCR偏差≤±10%);
  • 环境适应性:通过-40℃+85℃高低温循环(1000次)、1000小时湿热(60℃/95%RH)、振动(102000Hz,加速度2g)等可靠性测试,适配工业级与消费电子级应用;
  • 供货稳定性:具备月产能千万级的规模化生产能力,可满足终端客户的量产需求,减少供应链风险。

该电感凭借紧凑体积、稳定电性能及可靠工艺,成为高频小型化电路的优选无源器件之一。

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
