SMNR8040-151MT 磁胶屏蔽功率电感产品概述

一、产品基本定位与标识

SMNR8040-151MT是顺翔诺(SXN)品牌推出的表面贴装(SMD)磁胶屏蔽功率电感,型号标识包含明确的规格信息:

  • “8040”对应封装尺寸:8mm×8mm×4mm(长×宽×高);
  • “151”代表电感量:15×10¹=150μH;
  • “MT”指向核心特性:磁胶屏蔽(Magnetic Shielding)结构。

该产品专为中低功率电源电路设计,兼顾小体积与电流承载能力,适配高密度PCB布局场景。

二、核心电气参数解析

1. 电感量与精度

标称电感值为150μH,精度±20%,实际电感量范围在120μH~180μH之间,满足普通电源滤波、储能的精度需求,无需额外校准。

2. 电流承载能力

  • 额定电流(Irms):1.05A
    指连续工作状态下,电感量变化≤10%、温度上升≤40℃时的最大电流,是设计中需严格控制的连续工作阈值。
  • 饱和电流(Isat):1.1A
    指电感量下降30%时的峰值电流,是电路瞬间过载(如启动冲击、负载突变)的电流上限,需确保峰值电流不超过此值,避免电感储能能力骤降。

3. 直流电阻(DCR)

553mΩ(毫欧),是电感线圈本身的电阻损耗。在1A工作电流下,损耗功率为0.553W,属于同规格电感中的较低水平,有助于降低电源模块发热。

4. 屏蔽类型

磁胶屏蔽结构,相比非屏蔽电感:

  • 抑制电磁辐射(EMI),减少对周边敏感电路的干扰;
  • 磁胶固定线圈,提升抗振动、抗冲击性能,适配车载、工业等振动环境。

三、封装与结构优势

SMNR8040-151MT采用8040 SMD封装,具备三大结构优势:

  1. 小体积高密度:节省约30%板级空间,适配智能手机、路由器等小型化设备;
  2. 磁胶固定线圈:避免线圈松动,满足IEC 60068振动测试标准;
  3. 无裸露磁芯:降低磁芯碎裂风险,减少对人体的潜在磁辐射影响。

四、典型应用场景

该产品参数特性匹配多类中低功率电路:

  1. 消费电子电源:智能手机、平板的DC-DC降压转换器(如5V转3.3V/1A输出);
  2. LED驱动:小功率LED灯带、显示屏背光的恒流驱动电路;
  3. 车载电子:车载充电器、行车记录仪的电源模块(适配振动环境);
  4. 通信设备:路由器、交换机的电源滤波电路(抑制开关噪声);
  5. 工业控制:小型PLC、传感器节点的低压电源模块。

五、选型与使用注意事项

  1. 选型匹配:连续工作电流≤1.05A,峰值电流≤1.1A,避免过载;
  2. 焊接规范:回流焊峰值温度≤260℃,回流时间≤30s,避免高温损坏磁胶;
  3. 环境要求:储存温度-40℃+85℃,工作温度-20℃+125℃,相对湿度≤90%;
  4. 散热设计:若电流接近1.05A,需预留散热空间或配合散热片。

六、品牌与供货说明

顺翔诺(SXN)是国内电感专业品牌,产品通过RoHS、REACH环保认证,常规订单供货周期1-2周,定制订单3-4周,适合批量生产需求。

该产品以“小体积+低损耗+抗干扰”为核心优势,是中低功率电源电路的高性价比选型。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
