NTC 5D-5（RUILON 瑞隆源）产品概述
一、产品简介
NTC 5D-5 为插件式负温度系数热敏电阻（NTC），外形规格 D6.5×5mm，脚距 5mm，双引脚直插封装，型号标识为 NTC_D6.5X5MM_TM。标称阻值 5Ω（25℃），B 值（25℃/50℃）为 2700K，阻值精度 ±20%。本器件适用于温度感测、温度补偿和浪涌电流抑制等应用。
二、关键电气与热特性
- 标称阻值：5Ω（25℃）
- B 值：2700K（25℃/50℃）——表征阻值随温度变化的指数关系
- 阻值精度：±20%
- 最大稳态电流（25℃）：1A（超过需注意自热及寿命）
- 耗散系数（热功率系数）：6 mW/℃（表征器件在自由空气中升温所需功率）
- 热时间常数：20 s（响应速度，表示达到热稳态的典型时间）
- 工作温度范围：-40℃ ～ +150℃
三、主要应用场景
- 电源与电机类：浪涌电流抑制（串联作为启动限流元件）、软启动电路
- 测温与控制：作为温度传感元件或与电阻分压构成温度检测电路
- 温度补偿：在放大器、传感器或电池管理系统中对温漂进行补偿
- 消费电子及照明：LED驱动、充电器、家电等需兼顾体积与性能的场合
四、选型与使用注意
- 依据应用温度范围和所需阻值曲线选择合适的 B 值与阻值等级；本品 B=2700K，适合中高温区间的温度灵敏度需求。
- 最大稳态电流 1A 是在 25℃ 空气中测得的限制值，实际使用中若连续通过大电流需考虑自热、热耦合与散热条件，必要时选更大规格或并联/串联方案。
- 耗散系数 6 mW/℃ 表示器件在自由空气余热条件下的升温特性，使用时避免长时间在高功率下工作以减少热漂移和老化。
- 测量阻值时应使用低测量电流，避免自加热导致读数偏低（尤其在精密测温场合）。
五、安装与可靠性建议
- 插件封装便于手工焊接与替换；焊接时避免对器件主体长时间加热，推荐快速点焊并控制温度。
- 在高振动或潮湿环境中，应采取固定与密封保护，防止引脚疲劳和电气污染。
- 长期使用会有轻微阻值漂移，关键精度场合需考虑定期校准或选择精度更高的型号。
六、优势与局限
优势：结构简单、体积小、响应时间适中、适合大多数通用温度检测与限流场合。
局限：阻值精度 ±20% 较宽，非精密温度测量首选；承载高电流与高功率场合需注意自热和散热设计。
结语：NTC 5D-5（RUILON）为一款性价比较高的插件式 NTC，适合在一般电子电源、温度检测与补偿场合应用。选择与设计时注意电流、散热和测量方法，可获得稳定、可靠的工作表现。

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.
