奇力新(Chilisin)LVS606045-3R3M-N是一款磁胶屏蔽型表面贴装(SMD)功率电感,专为中等功率电源电路设计,兼顾电磁干扰(EMI)抑制与能效表现,是消费电子、车载及工业电源领域的常用元件。
该电感属于奇力新LVS系列功率电感,型号命名规则清晰:
作为SMD功率电感,其核心定位是为DC-DC转换、电源滤波等电路提供稳定的储能与滤波功能,同时通过磁胶屏蔽降低对外电磁辐射。
电感值为3.3μH±20%,公差范围符合工业级功率电感的常规要求,可满足多数开关电源的储能需求。3.3μH的电感值适配主流开关频率(200kHz~2MHz),避免因电感值过高导致体积冗余,或过低导致纹波过大。
额定电流为4.3A(通常指温升电流,即电感温度稳定时的最大允许电流),可覆盖中等功率应用(如12V转5V/3A的DC-DC模块),避免电流过载导致电感饱和(电感值骤降,影响电路稳定性)。
直流电阻为24mΩ,属于同封装、同电感值产品中的低损耗水平。低DCR可显著降低电流热损耗(4.3A电流下损耗仅约0.44W),提升电源转换效率,减少电路发热,延长系统寿命。
采用磁胶屏蔽结构,相比非屏蔽电感可减少80%以上漏磁,有效抑制EMI干扰,适合对电磁兼容性(EMC)要求较高的场景(如车载电子、医疗设备)。
表面贴装封装支持回流焊、波峰焊等自动化工艺,生产效率高,适合大规模量产。紧凑尺寸(6.0×6.0×4.5mm)可节省PCB空间,满足小型化产品(如笔记本、智能穿戴)的设计需求。
磁胶由铁氧体粉末与树脂混合制成,包裹线圈后既保持储能特性,又能吸收电磁辐射,同时增强机械强度,提升耐振动、耐冲击性能(适合车载等振动环境)。
结合参数与结构特点,该电感主要应用于:
奇力新作为全球知名被动元件制造商,产品通过RoHS 2.0、REACH等环保认证。LVS606045-3R3M-N的可靠性验证包括:
总结:该电感以紧凑封装、低损耗、高EMI抑制为核心优势,适配中等功率电源电路的多样化需求,是消费电子、车载及工业领域的高性价比选择。
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.
