NLCV32T-330K-PF — TDK 33μH 绕线片式功率电感产品概述

一、产品简介

NLCV32T-330K-PF 为 TDK 公司推出的一款绕线片式功率电感,标称电感值 33 μH,精度 ±10%,额定直流电流 240 mA,直流电阻(DCR)约 1.1 Ω,采用 1210 封装。该器件以紧凑体积实现较大电感量,适合用于需要低频滤波与能量储存的应用场合。

二、主要参数

  • 电感值:33 μH(±10%,代码 330)
  • 额定电流:240 mA(注意与实际工作电流和温升对应评估)
  • 直流电阻(DCR):1.1 Ω(典型值)
  • 类型:绕线片式(绕线功率电感)
  • 封装:1210(SMD,约 3.2 mm × 2.5 mm)
  • 品牌:TDK
  • 料号后缀 PF 通常用于卷带包装

三、特性与优势

  • 高电感密度:绕线结构在相同体积下可实现较高电感值,适合对电感量有要求但空间受限的设计。
  • 良好的纹波抑制能力:33 μH 的量级适合用作电源输入/输出滤波与隔离,降低低频干扰。
  • 标准化 SMD 封装:1210 封装兼顾装配可靠性与热性能,适用于自动贴装与回流焊流程。
  • 品牌与质量保障:TDK 提供可靠的制造与品质控制,适合要求稳定性与一致性的量产项目。

四、典型应用场景

  • 开关电源的输入/输出滤波与能量储存(尤其是低功率 DC–DC 降压/升压模块)
  • LED 驱动与背光电源的噪声抑制
  • 电池供电设备中的 EMI/射频干扰滤波
  • 工业控制、仪器仪表等对电感稳定性要求较高的低频电源回路

五、选型建议与注意事项

  • 电流裕量:额定 240 mA 为器件长期允许通过的电流,设计时应留有裕度,避免接近或超过该值引起温升或磁饱和(如工况中有较大纹波电流,应合并直流与纹波分量评估)。
  • DCR 与损耗:1.1 Ω 的 DCR 在功率损耗计算中不可忽视,功耗 P = I^2·DCR 会导致温升,需评估散热与系统效率影响。
  • 频率特性:绕线片式电感在低频段表现优良,但高频下可能出现寄生特性,需参考厂方频率响应曲线评估滤波效果。
  • 环境与寿命:在高温或潮湿环境下应参考 TDK 的温度系数与寿命数据,必要时选择具有更高电流或更低 DCR 的型号。

六、封装与可靠性

1210 SMD 封装适合常规回流焊工艺,建议遵守 TDK 提供的焊接温度曲线和贮存条款,避免长时间潮湿暴露。绕线结构对机械振动相对敏感,贴装时应确保基板支撑良好并避免过大的弯曲应力。

七、典型电路使用建议

  • 作为输入滤波器元件时,配合合适的旁路电容形成 LC 或 π 型滤波网络,可有效抑制开关噪声与输入纹波。
  • 在 DC–DC 转换器中,评估纹波电流与平均电流后可决定是否并联多颗电感或采用电感与电容并联的方案以降低等效阻抗。
  • 进行原型验证时,应测量在工作电流下的实际感值与温升,确认不发生显著感值下降或过热情况。

总结:NLCV32T-330K-PF 是一款适用于低功率电源滤波与能量储存的绕线片式功率电感,凭借 33 μH 电感量与标准 1210 封装,在空间受限且对低频滤波要求较高的应用中表现良好。选型时请综合考虑工作电流、DCR 导致的损耗及系统散热条件。若需更详细的频率特性、温度系数或可靠性试验数据,建议参考 TDK 官方规格书或联系技术支持获取完整参数表。

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
