NTC8D-9 是瑞隆源(RUILON)提供的一款负温度系数(NTC)热敏电阻元件,采用插件封装,脚距(引脚间距)为7.5mm。其典型静态阻值为 8Ω(按标准测试温度测得),工作温度范围宽达 -40℃ 至 +175℃,适用于需要可靠温度响应和良好耐高温性能的电子及电气应用场景。
NTC8D-9 采用传统插件式封装,元件体积紧凑,引脚间距为7.5mm,便于手工和波峰/回流前后处理的焊接与固化。封装对元件的机械保护与散热路径进行了基础设计,适合穿孔安装的电路板布局或夹持式传感器装配。
作为负温度系数热敏电阻,NTC8D-9 的阻值随温度上升而下降。该特性使其在温度测量、温度补偿和过流保护(或配合其他电路实现)中具备实用价值。关键性能关注点包括:
注意:若用于浪涌限流(NTC inrush),需核对冷阻、峰值电流、能量承受能力等参数,确保可靠性。
NTC8D-9 的工作温度范围说明其在低温与高温环境下均能保持基本功能,但长期可靠性还取决于电流、功耗、反复热循环及潮湿环境的影响。在发生频繁热循环或高湿、高盐雾环境时,建议做加速老化与耐候性验证,或采用防护处理(如涂层、密封)以延长使用寿命。
NTC8D-9 是一款结构简单、封装易用、工作温度范围宽的负温度系数热敏电阻,适合于多种温度检测与补偿场合。选择时应关注阻值基准、温度响应曲线、功耗能力及应用场合的特殊要求。欲获得完整电气与机械参数(如 B 值、最大电流、功率规格、外形尺寸图及焊接规范),建议联系 RUILON(瑞隆源)或参考其详细产品资料与样品测试报告。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
