NTC5D-13 产品概述
一、产品简介
NTC5D-13 是 RUILON（瑞隆源）出品的一款插件式负温度系数热敏电阻，专为浪涌吸收、吸弧、过流保护与启动涌流抑制设计。器件在常温下阻值较大，通过流经电流自发发热后阻值下降，从而在电源启动或浪涌事件中限制电流峰值，保护电路与元器件安全。
二、主要技术参数
- 标称阻值（25℃）：5 Ω
- B值（25℃/50℃）：2700 K（典型）
- 阻值精度：±20%
- 最大稳态电流（25℃）：5 A
- 工作温度范围：-55 ℃ ～ +200 ℃
- 耗散系数（热阻）：15 mW/℃
- 热时间常数：1.13 min（约68 s）
- 引脚间距：7.5 mm（插件封装）
示例计算：按 B 值估算，50℃ 时阻值约为 5 Ω × exp[2700*(1/323.15-1/298.15)] ≈ 2.5 Ω（仅供参考，实际受公差影响）。
三、特点与优势
- 有效抑制启动瞬时涌流，保护电源变压器、整流桥与电容等元件；
- 工作温度范围宽、耐热性能好，适合高温环境；
- 耗散系数较低，热响应稳定，热时间常数短，能快速达到稳态；
- 插件式封装便于装配与更换，7.5 mm 引脚间距适配常见 PCB 布局。
四、典型应用
- 开关电源/适配器启动涌流抑制（搭配旁路继电器使用效果最佳）；
- LED 驱动、电机驱动与充电器的过流与浪涌保护；
- 家电与工业设备的吸弧、灭弧、防打火应用；
- 电源防浪涌、保护电阻器与低功耗热敏场景。
五、选型与使用建议
- 若电路存在高速、高能量浪涌，请咨询厂商获取脉冲电流和能量吸收能力参数；
- 工作环境长期高温时，应考虑器件老化及阻值漂移，必要时增加安全裕度；
- 对于要求快速回复低阻态的系统，建议设计旁路继电器或恒流路径以降低长期发热与功耗。
六、安装与可靠性注意事项
- 插件安装时避免过热焊接，推荐手工或波峰焊温度/时间控制在厂家建议范围内；
- 注意引脚固定与绝缘距离，防止机械振动导致引脚疲劳；
- 存储建议干燥、常温，避免潮湿与强酸碱环境。
七、包装与订购信息
型号：NTC5D-13；品牌：RUILON（瑞隆源）；封装：插件 P=7.5mm；阻值/精度/电气参数请以采购协议或样品检测为准。大量采购或定制需求可联系供应商技术支持，获取更详细的脉冲能力和可靠性验证资料。
若需电气特性曲线、脉冲承受能力或具体应用电路参考图，可提供电路参数与使用场景，我方可协助校核与优化选型。

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.
