RL0603N503F4150FTF NTC热敏电阻产品概述

一、核心电参数总览

RL0603N503F4150FTF是一款高精度贴片NTC热敏电阻,核心电参数满足工业级与消费电子的双重需求:

  • 标称阻值:25℃环境下为50kΩ,阻值精度±1%,可直接用于高精度温度计算无需额外校准;
  • B值特性:提供双温度区间参数——25℃/50℃区间B值为4150K(精度±1%),25℃/85℃区间为4209K,覆盖中低温到中高温的应用场景;
  • 功率与电流:额定功率100mW(长期工作限值),25℃稳态最大电流130μA,需注意电流随温度升高而降低(电阻值下降);
  • B值精度:±1%的B值一致性,保证批量产品的温度-电阻曲线稳定。

二、封装与物理尺寸

采用标准0603贴片封装(英制代码,对应公制1608),具体物理尺寸为:

  • 长度:1.6mm;
  • 宽度:0.8mm;
  • 厚度:行业标准约0.5mm(无额外封装差异)。

该封装适配高密度PCB布局,可广泛用于小型化电子设备(如可穿戴、便携终端),无需额外降额设计。

三、温度特性与环境适应性

产品的温度相关参数直接决定应用场景适配性:

  • 工作温度范围:-40℃至+125℃,覆盖工业级温度要求,可在低温环境(如北方户外设备)或高温环境(如电机绕组)稳定工作;
  • 耗散系数:1mW/℃,即电阻自身功率损耗每增加1mW,表面温度比环境高1℃——设计时需通过限流控制功率,避免自热导致温度测量偏差;
  • 热时间常数:5s,指电阻温度变化至环境温度变化63.2%的时间,适配中速温度监测场景(如家电温控),既避免响应过快误触发,又满足实时性需求。

四、功率与电流限制设计要点

需注意以下参数限制,避免产品损坏或性能衰减:

  1. 额定功率:100mW为长期连续工作的最大功率,瞬态工作需参考功率-时间曲线(通常1s内可承受1.5倍额定功率);
  2. 稳态电流:25℃时130μA为最大值,实际应用中需根据工作温度核算(如85℃时电阻约10kΩ,最大电流约3mA,但需结合功率限制≤100mW);
  3. 自热影响:若工作电流接近最大值,需预留散热空间,避免自热导致温度监测误差超过0.5℃。

五、品牌与典型应用场景

该产品由RUILON(瑞隆源) 生产,瑞隆源专注热敏电阻研发10余年,产品以高一致性、低漂移著称。典型应用包括:

  • 消费电子:智能手机电池温度监测、智能手表环境温度感知;
  • 家电领域:空调蒸发器温度控制、冰箱压缩机过温保护;
  • 工业控制:小型仪器仪表温度测量、光伏逆变器散热监测;
  • 电源管理:开关电源过温保护、充电器温度闭环控制。

六、关键性能优势总结

  1. 高精度双参数:阻值±1%、B值±1%,满足医疗设备、工业计量等对精度要求较高的场景;
  2. 宽温稳定:-40℃~+125℃工作范围,无性能衰减(1000小时老化后漂移≤0.2%);
  3. 紧凑适配:0603封装节省PCB空间,适配小型化设计趋势;
  4. 批量一致性:批量产品参数离散度≤0.5%,便于规模化生产;
  5. 成本可控:在高精度NTC中具备价格优势,适合中高端产品批量应用。

该产品通过了RoHS认证,符合欧盟环保要求,可直接用于出口产品设计。如需进一步参数手册或样品申请,可联系瑞隆源官方技术支持。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
