SM5845-101KT是顺翔诺(SXN)品牌推出的一款非屏蔽表面贴装功率电感,针对中等功率需求的电子电路设计,兼具成本优势与紧凑尺寸,适用于多种消费电子及小型设备的电源管理场景。
顺翔诺(SXN)作为国内电感研发生产厂商,其产品线覆盖功率电感、贴片电感等品类。SM5845-101KT属于该品牌经济型非屏蔽功率电感,定位为“中等电流、小尺寸、低成本”的电源储能/滤波元件,适配对电磁干扰(EMI)要求不高的电路设计。
SM5845-101KT的电气参数经过标准化设计,关键指标及意义如下:
电感标称值为100uH,精度**±10%**(命名“101”对应“10×10¹=100uH”,符合行业规则)。该精度满足绝大多数电源滤波、DC-DC转换的储能需求,无需额外校准即可稳定工作。
直流电阻为700mΩ,直接影响电感功耗(P=I²×R)。在额定电流520mA下,功耗约0.19W,属于中等水平,需注意电路布局散热,避免局部过热。
SM5845-101KT采用表面贴装(SMD)封装,尺寸为5.8mm×5.2mm(长×宽),高度约2.0mm(行业常规),属于紧凑型贴片电感,适配自动化贴装生产线,可集成于高密度PCB设计中。
作为非屏蔽电感,其结构简单、成本较低,但需注意:非屏蔽设计会产生电磁辐射,若电路对EMI要求较高(如高频通信模块),需搭配屏蔽罩或选择屏蔽电感。
SM5845-101KT的参数特性使其适用于以下场景:
为确保稳定工作,需注意以下几点:
SM5845-101KT作为顺翔诺经济型非屏蔽功率电感,以100uH±10%电感值、520mA额定电流、紧凑SMD封装为核心优势,兼顾成本与性能,适用于中等功率、低EMI要求的电路。在电源管理、消费电子等领域具有广泛应用前景,是小型化设备设计的实用选择。

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.
