顺络MPH201210S1R5MT是一款0805封装磁胶屏蔽功率电感,属于小尺寸高频功率电感范畴,专为紧凑空间的电源电路设计。核心参数明确:
小尺寸高密度封装
0805封装体积紧凑(长2.0mm×宽1.2mm×高1.0mm),兼容标准SMT生产线,可直接贴装于PCB表面,无需额外焊接工艺,适配智能手机、智能手表等便携设备的高密度布局需求。
磁胶屏蔽设计
采用磁胶包裹铁氧体磁芯结构,相比裸露磁芯电感:
精细绕线工艺
采用高导电率漆包线绕制,线圈紧密均匀,减少分布电容,提升高频响应速度;绕线与磁芯匹配度高,降低高频损耗。
电感值稳定性
标称1.5μH±20%,在1MHz以下工作频率范围内,电感值变化率≤5%(顺络同类产品典型特性),可满足DC-DC转换器、LDO滤波等电路的储能需求。
低损耗特性
DCR仅160mΩ,在额定电流700mA下,导通损耗(I²R)约为78mW,远低于同封装普通电感(部分竞品DCR达200mΩ以上),可提升电源转换效率,减少设备发热。
电流与温度特性
工作温度范围为-40℃~+85℃(部分批次可扩展至+125℃,需确认具体 datasheet);在环境温度≤60℃时,额定电流可满额使用;若温度超过85℃,需将电流降额至500mA以下,避免电感饱和。
便携式电子设备
智能手机、平板电脑、智能手表的电源管理模块(PMIC):用于DC-DC降压/升压转换器的储能电感,适配紧凑PCB空间,同时抑制EMI干扰(避免影响射频信号)。
消费类电子终端
路由器、机顶盒、智能家居设备:作为电源滤波电感,降低纹波噪声,提升设备稳定性;磁胶屏蔽特性符合家电EMC标准。
物联网(IoT)终端
小型传感器、智能门锁等低功耗设备:低DCR特性减少电池损耗,延长续航时间;小尺寸适配终端微型化设计。
小型工业设备
工业传感器、手持检测仪器:宽温特性适应户外或车间环境,抗振动性能满足设备移动需求。
可靠性测试
产品通过顺络内部可靠性测试:温度循环(-40℃+85℃,1000次)、振动测试(102000Hz,加速度2g)、湿度测试(85℃/85%RH,1000h),符合RoHS环保标准(无铅无卤)。

顺络MPH201210S1R5MT凭借小尺寸、低EMI、低损耗等核心优势,成为便携电子、消费类电子等领域电源电路的高性价比选择,适配对空间和电磁兼容要求严格的设计场景。
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.
