CS0603-R18J-S是奇力新(Chilisin) 推出的高频贴片电感,属于0603封装系列(英制尺寸1.6mm×0.8mm,对应公制1608)。该产品针对小体积、低损耗、高频应用设计,广泛适配便携设备、物联网模块等场景,是射频电路中阻抗匹配、滤波、谐振的核心元件之一。
电感标称值为180nH,精度等级为**±5%**(型号中“J”为精度代码,对应E24系列±5%公差)。该精度满足绝大多数射频电路的阻抗匹配需求,例如Sub-GHz频段的无线通信模块,无需额外校准即可实现稳定的信号传输。
额定电流为240mA,定义为电感在最大温升≤40℃(常规标准)时的连续工作电流。需注意:峰值电流不得超过额定电流,否则会导致磁芯饱和(电感值骤降)或线圈过热(DCR损耗加剧)。结合其1.25Ω直流电阻(DCR),实际功率损耗为(I^2R),240mA下损耗仅约72mW,符合低功耗设计要求。
Q值为25@100MHz,是电感“储能能力/损耗”的比值(公式:(Q=2πfL/R))。高Q值意味着电感在谐振电路、射频匹配网络中损耗更低,例如100MHz左右的LC滤波器可获得更窄的带宽与更高的信号纯度。
自谐振频率为990MHz,即电感与自身寄生电容谐振的频率。当工作频率远低于SRF(建议≤70%SRF,即≤693MHz)时,电感保持“感性”特性;若接近或超过SRF,电感会表现为电容,导致电路性能失效。因此该产品更适合Sub-GHz频段(如868MHz、915MHz ISM频段)应用。
体积仅1.6mm×0.8mm,厚度约0.8mm,适配高密度PCB设计(如智能手机、可穿戴设备的射频模块),可有效节省空间,满足小型化趋势。
采用高磁导率铁氧体磁芯+精细绕线工艺:
如低功耗蓝牙(BLE)、物联网(IoT)模块(868MHz/915MHz)、无线传感器网络,利用其高Q值实现信号滤波与阻抗匹配,降低传输损耗。
小型DC-DC转换器(输出电流≤200mA)的输出滤波,或射频电路的电源去耦,抑制高频噪声干扰,提升电路稳定性。
100MHz左右的LC谐振电路(如无线耳机的射频前端)、射频放大器的输入/输出匹配,利用高Q值优化信号增益。
智能手环、蓝牙耳机、智能手表的射频模块,适配小体积设计需求,同时满足低功耗要求。
实际工作电流建议不超过额定电流的80%(≤192mA),尤其在高温环境(如车载、工业场景)下,需进一步降额以避免性能漂移。
避免在接近990MHz的场景使用(如2.4GHz WiFi),若需高频应用需选择SRF更高的型号(如奇力新CS0603系列的SRF≥2GHz版本)。
焊接后避免弯曲PCB(弯曲半径≥10mm),防止电感线圈断裂或磁芯开裂。
CS0603-R18J-S是奇力新针对高频小功率应用优化的贴片电感,兼具小体积、低损耗、高Q值等特点,适配Sub-GHz射频通信、便携设备等场景,是物联网、可穿戴领域的高性价比选择。其参数稳定、工艺可靠,可满足批量生产与长期使用需求。

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.
