SMD4532-090NF 产品概述

一、概述

SMD4532-090NF 是雷卯电子(Leiditech)推出的一款面向瞬态过电压保护的表面贴装元件。该器件以紧凑的 SMD 封装实现高能量脉冲放电能力,适用于需要在有限空间内提供高水平浪涌和冲击保护的电路。器件结构为双端电极(2 极),设计用于直流/脉冲过电压抑制场景。

二、主要规格

  • 脉冲放电电流(Ipp):2 kA
  • 直流击穿电压(Vdc):90 V
  • 冲击击穿电压(Vimp):600 V
  • 极数:2(双端电极)
  • 极间电容:1 pF(典型)
  • 外形尺寸(典型):宽 3.2 mm × 长 4.5 mm × 高 2.7 mm
  • 精度/公差:±30%(器件额定值制造公差)
  • 封装形式:SMD(贴片)

三、主要特性

  • 高脉冲承受能力:单次脉冲放电电流可达 2 kA,适合应对较大能量的浪涌事件。
  • 低极间电容:约 1 pF,适合信号线或对高频敏感电路的保护,能把寄生影响降到最低。
  • 紧凑封装:4532 型 SMD 尺寸便于在空间受限的电子设备中布置保护元件。
  • 宽耐压范围:直流击穿电压 90 V,冲击耐压可达 600 V,适配中低压直流或工业控制总线防护要求。
  • 制造公差控制:典型公差 ±30%,在选型和可靠性评估时需考虑该范围。

四、典型应用场景

  • 电源输入侧与直流总线浪涌保护(中低压系统)。
  • 工业控制器、继电器驱动及配电模块的过压/过流冲击防护。
  • 通讯接口、电信设备及基站设备的瞬态干扰抑制(特别要求低电容时)。
  • 现场仪表、传感器接口及其它对体积和寄生电容敏感的电子模组。

五、封装与机械尺寸

SMD 封装,典型外形尺寸:宽 3.2 mm × 长 4.5 mm × 高 2.7 mm。双端电极布局适合直接在信号或电源线的 PCB 路径上实现低阻抗接地/旁路通道。实际焊盘形状与尺寸请参照厂方封装图纸以保证焊接可靠性与散热性能。

六、使用建议与注意事项

  • 选型时请根据系统的最大浪涌规格、重复冲击次数及典型脉冲波形(如 8/20µs 等)确认器件是否满足能量吸收需求;厂方数据手册中有关测试波形与寿命的数据应作为最终依据。
  • 布局建议将器件放置于被保护线路的接近输入端或连接器处,以缩短回路电感、提高保护效率。
  • 注意焊接工艺温度窗口和回流曲线,避免因过热影响器件特性。
  • 在高重复冲击场合,应评估热累积与器件退化,必要时采用并联/串联或外加限流元件分担能量。
  • 极间电容虽低,但在超高频应用中仍需评估对信号完整性的影响。

七、品牌与质量

品牌:Leiditech(雷卯电子)。建议在设计阶段索取完整数据手册、可靠性测试报告和样片进行实测匹配。对于关键系统应用,建议与供应商确认批次一致性、出货检验项目及存储/运输条件,以保证长期稳定性与一致性。

总结:SMD4532-090NF 是一款适合空间受限且需承受大能量瞬态的 SMD 保护器件,兼顾低极间电容与较高脉冲电流能力。在具体应用中,请结合厂方完整资料及系统实际脉冲条件进行最终选型与布局设计。

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
