NTC 5D-7 产品概述
一、产品简介
NTC 5D-7 是 RUILON（瑞隆源）推出的一款插件式负温度系数热敏电阻，主要用于浪涌吸收、过流保护与吸弧/灭弧等场合。器件在冷态时具有较高阻值，通电加热后电阻迅速下降，从而限制瞬时涌流并随工作温度稳定到低阻态，适用于对启动涌流、浪涌冲击与接触击穿要求严格的电源与负载设备。
二、主要性能参数
- 标称阻值（25℃）：5 Ω
- 最大稳态电流（25℃）：2 A
- 工作温度范围：-40 ℃ ～ +150 ℃
- 封装形式：插件（P = 5 mm，脚间距 5 mm）
- 品牌：RUILON（瑞隆源）
三、产品特性
- 有效抑制启动与开关瞬态电流，降低对电路元件的冲击；
- 随温度上升电阻迅速下降，实现自恢复式保护，不需要外部控制；
- 宽温度适应性（-40 ℃ 至 +150 ℃），适合高温工况与恶劣环境；
- 插件封装，焊接与更换方便，脚距5mm 便于设计布板与机械固定；
- 低成本、寿命长、维护简单，符合多数工业与消费类设备的可靠性要求。
四、典型应用场景
- 开关电源、适配器与充电器的浪涌/启动电流限制；
- LED 驱动、电机驱动与变频器的过流缓冲与保护；
- 家用电器（洗衣机、电吹风、电磁炉等）防打火、吸弧与灭弧；
- 工业控制、电源配电与通讯设备的防浪涌保护；
- 作为电源NTC、保护电阻或低功耗热敏元件用于温度敏感电路。
五、选型与使用注意事项
- 请以器件标称阻值（25℃）与最大稳态电流为基础比对电路启动电流与持续电流，确保稳态电流不超过 2A；
- 考虑器件在通电后的自发热与周围温度累积，必要时预留散热空间并避免近邻热源；
- 避免频繁的大能量浪涌或长期超额放电，否则可缩短器件寿命或改变阻值特性；
- 焊接时注意温度与时长，遵循插件元件焊接规范，防止机械应力损伤引脚及本体。
六、包装与可靠性
- 插件式包装便于手工或波峰/选择性焊接装配；
- 在符合使用规范条件下，NTC 5D-7 具有良好的循环稳定性与长寿命特性；
- 出厂前经过常规温度与电流应力筛选，适配工业级应用要求。
七、品牌与服务
RUILON（瑞隆源）专注于热敏与保护类元器件研发与制造，提供产品技术资料与应用支持。如需详细电气特性曲线、浪涌承受能力测试或样品评估建议联系供应商获取完整数据手册与可靠性报告。
以上为 NTC 5D-7 的产品概述，适合在电源防浪涌、启动限制与吸弧防护等多种场景中使用。

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.
