该产品为Sumida(胜美达)推出的一体成型功率电感,核心参数及应用意义如下:
采用磁芯一体化封装,无裸露磁路,可有效抑制电磁干扰(EMI),降低对周边敏感电路(如传感器、通信模块)的影响;同时提升机械强度,抗振动、抗冲击能力优于传统绕线电感,适合严苛环境(如汽车发动机舱、工业现场)。
额定电流19A、饱和电流29A,可覆盖中大功率电源的连续工作与峰值负载需求,避免电感饱和导致的输出电压波动、效率下降等问题。
3.3mΩ的直流电阻大幅降低铜损,以19A额定电流为例,单路损耗仅约1.19W,可提升电源转换效率至90%以上,同时降低工作温度,延长产品寿命。
支持**-40℃~125℃**工作温度范围(符合工业与汽车级应用标准),极端温度下仍保持稳定的电感特性,无明显漂移。
SMD封装符合主流电子制造工艺,可通过回流焊实现自动化贴装,适配紧凑的PCB设计(如笔记本电源、车载模块)。
该产品针对中大功率电源需求优化,核心应用场景包括:
Sumida胜美达作为全球知名电感制造商,该产品具备以下品质优势:
该产品凭借高电流、低损耗、抗干扰等特性,成为工业、汽车、通信等领域中大功率电源电路的优选功率电感。

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.
