CYH125-22UH是首韩(SHOU HAN)推出的一款中功率贴片电感,采用12.3×12.3×6mm SMD封装,针对DC-DC转换器、电源滤波等场景优化了电感量、电流承载能力与损耗性能,兼顾紧凑尺寸与可靠性,适用于车载电子、工业控制、消费电子等多领域。
该电感属于中功率贴片电感,核心针对电流需求在5A左右、电感量20μH级别的电路设计,典型应用场景包括:
CYH125-22UH的参数针对中功率场景做了均衡设计,关键参数如下:
电感值:22μH ±20%
电感量是储能与滤波的核心指标,±20%的精度满足大多数中功率电源的设计需求(无需过高精度的额外成本),22μH的电感量可有效抑制DC-DC转换中的纹波(典型降压电路中,电感量与纹波成反比,22μH能将输出纹波控制在100mV以内,符合多数设备要求)。
额定电流:5.4A
此处额定电流为饱和电流(功率电感核心指标,指电感量下降30%时的电流),5.4A的承载能力可覆盖90%以上的中功率电路(如12V转5V/2A的DC-DC,最大峰值电流约5A,满足裕量需求)。
直流电阻(DCR):23.4mΩ
DCR直接影响铜损(损耗=I²×DCR),23.4mΩ在同尺寸(12.3×12.3mm)电感中属于较低水平:以5.4A额定电流计算,铜损约为0.68W,热损耗可控,无需额外散热片即可稳定工作。
封装尺寸:12.3×12.3×6mm(SMD)
贴片封装兼容回流焊工艺,贴装效率高;紧凑尺寸节省PCB空间(比传统1210封装略大,但承载电流提升30%),适合板级空间紧张的设备(如便携车载终端)。
当电路满足以下条件时,可优先选择CYH125-22UH:
CYH125-22UH作为首韩推出的中功率贴片电感,凭借均衡的性能参数(22μH/5.4A/23.4mΩ)、紧凑的SMD封装、宽温可靠性,成为车载电子、工业控制、消费电子等领域DC-DC转换与滤波电路的高性价比选择。其参数覆盖了多数中功率场景的需求,同时兼顾了生产效率与板级空间优化,适合批量应用。

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.
