村田LQW15AN33NG80D属于高频功率电感系列,专为小型化无线通信设备设计,核心参数如下:
高频特性优异
针对1GHz以上高频频段优化,陶瓷芯体的低损耗特性使电感在射频场景下Q值(品质因数)更高,减少信号衰减,适合无线通信的匹配、滤波电路。
小型化设计
0402封装体积仅1.0mm×0.5mm×0.5mm,是便携式设备(如智能手机、智能穿戴)实现轻薄化的关键元件,可大幅节省PCB布局空间。
低损耗与稳定性
336mΩ低DCR减少直流功率损耗,同时陶瓷芯体的电感值温度系数(TCC)控制在±100ppm/℃以内,温度变化对电感值影响极小,长期使用性能稳定。
抗干扰能力
虽为非屏蔽设计,但陶瓷芯体的磁漏控制优于传统铁氧体磁芯,结合村田的结构优化,可降低对周边电路的电磁干扰(EMI)。
无线通信终端
智能手机、平板电脑的射频前端电路(如PA功率放大器输出匹配、天线调谐网络),需小尺寸电感优化信号传输效率。
短距离无线模块
蓝牙(Bluetooth 5.0/5.1)、WiFi(802.11a/b/g/n/ac)、ZigBee模块的滤波与阻抗匹配电路,匹配33nH电感值的高频特性。
物联网(IoT)设备
智能穿戴(手表、手环)、智能家居传感器节点的无线通信单元,满足低功耗、小型化需求。
小型电源电路
便携式设备的低功率DC-DC转换电路(如1-5V输出),低DCR特性提升电源转换效率。
RFID与NFC
高频RFID标签(13.56MHz)、NFC模块的天线匹配网络,保障信号读写距离与稳定性。
村田品质体系
遵循村田全球统一的质量控制流程,每批次产品经过全参数测试,不良率低于10ppm,符合工业级可靠性要求。
焊接与机械可靠性
符合J-STD-020焊接标准,支持回流焊、波峰焊工艺,焊接后无开裂、虚焊问题;封装结构坚固,可承受便携式设备的振动、跌落冲击。
长期稳定性
陶瓷芯体材料老化率极低,2000小时高温存储(125℃)后电感值变化≤±1%,保障设备长期使用性能。
汽车级兼容
部分批次通过AEC-Q200汽车级可靠性测试,可扩展至车载无线通信(如车联网T-Box)场景。
村田LQW15AN33NG80D凭借小型化、低损耗、宽温稳定等特点,成为消费电子、物联网及射频领域的主流电感选型,可有效提升设备的信号性能与可靠性。
Request for quote
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.
