SMD4532-1000 产品概述 — RUILON（瑞隆源）
一、产品简介
SMD4532-1000 是 RUILON（瑞隆源）推出的一款表面贴装陶瓷气体放电管（GDT），封装规格为1812（4.5mm × 3.2mm × 2.7mm），双极极数设计。该器件以气体击穿放电为工作机制，用于在高能脉冲或雷电冲击时迅速将过电压导通至地，从而保护下游电路免受大能量瞬态冲击损坏。
二、主要技术参数
- 极数：2
- 直流击穿电压（Vdc）：1 kV（±20%）
- 冲击击穿电压（Vimp）：1.6 kV
- 脉冲放电电流：2 kA（峰值）
- 极间电容：0.5 pF（典型）
- 工作温度范围：-40 ℃ ～ +90 ℃
- 尺寸：长度 4.5 mm，宽度 3.2 mm，高度 2.7 mm
- 封装：1812（SMD）
三、产品特点
- 高能耐受：单次脉冲放电电流可达 2 kA，适合直击雷及大能量感应浪涌的一级防护。
- 高压耐受：直流耐压约 1 kV，冲击击穿可达 1.6 kV，能有效钳位高幅值瞬态。
- 极低电容：约 0.5 pF 的极间电容，适合用于对信号完整性要求高的通信与数据线保护。
- 温度与封装稳定：-40 ℃ 至 +90 ℃ 的工作温度范围以及标准1812 SMD封装，便于自动贴装与批量生产。
四、典型应用场景
- 电信基站、光纤收发端子、电表与配电端口的雷击与浪涌防护。
- 网络设备、路由器、交换机端口的过压保护，尤其适合对低电容有严格要求的高速信号线路。
- 工业控制、安防摄像头、户外终端等需要抗雷击能力的电子设备。
五、使用与注意事项
- 推荐将 GDT 作为一级高能浪涌吸收元件，与快响应的 TVS 二极管并联使用以覆盖快速小能量脉冲与慢大能量脉冲两类干扰。
- 贴装及回流焊遵循标准 SMD 工艺，建议参照制造商的回流曲线与焊盘设计，避免过度机械应力。
- 存储与运输应避免剧烈振动和潮湿环境，防止密封或陶瓷外壳损伤。
- 放电后若器件出现参数漂移或反复触发，应进行更换以确保系统可靠性。
六、可靠性与包装
RUILON 提供工业级产品一致性检验与批次测试，常见以卷带（Tape & Reel）方式供货，便于SMT贴装线使用。具体环境应力试验、寿命与冲击测试数据请参考厂家详细资料或样品测试结果。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
