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:
产品参数针对高频小电流射频场景优化,关键指标如下:
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。
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%)。
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。
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。
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)。
该产品因小封装、高频低损耗特性,主要适用于以下场景:
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。
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。
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。
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。
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。

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.
