产品概述:BLM21PG300SN1D

BLM21PG300SN1D是由知名电子元器件制造商村田(muRata)生产的一款表面贴装型磁珠,广泛应用于电源线滤波器,旨在改善设备的电磁兼容性(EMC)并有效降低高频噪声。这款磁珠具有卓越的参数指标和优异的性能,适用于高要求的电子设备。

主要参数

  1. 阻抗与频率特性:

    • BLM21PG300SN1D的典型阻抗为30Ω,测试频率为100MHz,能够有效地过滤掉高频噪声,确保信号的稳定性。这一阻抗特性使其在高频应用场合中表现出色。
  2. 额定电流与直流电阻:

    • 该磁珠的最大额定电流为4A,能够承受较高电流负载,从而适应对电源线的要求。其最大直流电阻(DCR)为14毫欧,这一低阻抗特性可以有效减少在工作过程中因电流通过元件而产生的功率损耗,提高了设备的能效。
  3. 工作温度范围:

    • BLM21PG300SN1D的工作温度范围为-55°C至125°C,这使得该磁珠能够在极端环境下稳定工作,适合汽车、工业设备和消费电子等广泛的应用领域。
  4. 封装与尺寸:

    • 该型号采用0805(2012公制)封装,具有极小的体积(约2.00mm x 1.25mm)和高度(最大值为1.05mm),便于紧凑布局的电子设备中使用。此类小型封装的设计使得该元件能够在空间受限的电路板中轻松集成。

应用场景

BLM21PG300SN1D适用于多种电子设备的电源线滤波,特别是在需要有效抑制电磁干扰(EMI)的应用中。以下是一些具体的应用场景:

  1. 消费电子产品:

    • 在智能手机、平板电脑及其他便携设备中,BLM21PG300SN1D可用于电源段,减少对信号的干扰,并提高整体性能。
  2. 汽车电子:

    • 在汽车的电子控制单元(ECU)和其他信息娱乐系统中,此磁珠可确保电源线清洁,防止困难的EMC问题,提高汽车的稳定性和可靠性。
  3. 工业设备:

    • 在复杂的工业控制系统中,BLM21PG300SN1D非常适合用于电源管理,以确保在恶劣环境条件下的安全稳定运行。
  4. 计算机和网络设备:

    • 伴随网络设备对于高速信号传输的需求,使用该磁珠已经成为提高数据传输的清晰度和稳定性的一个有效解决方案。

优势

  • 低直流电阻:低DCR值使得BLM21PG300SN1D在高电流工作时发热量极小,提升了系统的可靠性与安全性。
  • 高频特性:在高频环境下,能够提供良好的阻抗特性,从而满足严苛的EMI/EMC要求。
  • 宽广的工作温度范围:确保了在各种恶劣环境下的稳定性,适合多种市场需求。

总结

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
