SDCL0603Q3N0ST02B03是顺络电子(Sunlord) 推出的一款微小型叠层贴片电感,属于高频小信号电感范畴。其核心标识对应明确:
该产品的电气参数精准匹配中高频射频及小功率电路需求,关键参数如下:
采用叠层工艺实现高精度电感值控制,偏差通常在±5%以内(常规商用级标准),适用于对电感匹配精度要求较高的射频电路(如滤波器、阻抗匹配网络)。
指环境温度25℃时,电感允许的最大直流工作电流(若工作温度升高,需按顺络降额曲线适当降低电流)。该电流承载能力可满足小型物联网设备、蓝牙模块等小功率电路的电源纹波抑制需求。
低DCR设计减少了电感自身的功率损耗(P=I²×R),在450mA工作电流下,损耗仅约50mW,可有效提升电路效率,避免因发热导致的性能漂移。
Q值是电感储能与损耗的比值,直接影响电路插入损耗。500MHz频段下Q值达13,说明该电感在中高频段(如蓝牙低功耗、ISM频段)的能量损耗极低,能显著提升射频链路的信号质量。
电感存在寄生电容(叠层结构的层间电容),当工作频率达到SRF时,电感与寄生电容谐振;超过SRF后,电感呈容性,失去电感功能。因此该产品适用频率范围为DC~9GHz,覆盖主流射频应用(2.4GHz、5GHz WiFi/蓝牙、ISM频段等)。
0201英制封装是目前电子设备小型化的核心封装之一,物理尺寸仅0.6mm×0.3mm×0.3mm(长×宽×高),适配手机、智能穿戴、无线模块等高密度PCB设计。叠层工艺的优势在于:
该产品的参数特性决定了其主要应用于中高频小信号电路,典型场景包括:
对比同类0201封装叠层电感,SDCL0603Q3N0ST02B03的核心优势在于:
该产品凭借精准的参数匹配、优异的高频性能及小体积设计,成为当前无线通信、物联网等领域的主流选型之一,可有效满足高密度、低损耗的电路设计需求。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
