RTT025900FTH 厚膜贴片电阻产品概述

一、产品基本信息

RTT025900FTH是RALEC(旺诠) 推出的厚膜贴片电阻,采用0402 封装(英制尺寸,对应公制1005),属于小型化贴片电阻范畴。该型号针对常规精度、宽温应用场景设计,是旺诠电阻产品线中覆盖中低端稳定需求的经典型号,广泛适配自动化SMT贴装工艺。

二、核心电性能参数

  1. 阻值与精度:标称阻值590Ω,精度±1%,满足大多数电子电路对电阻值的稳定控制需求(误差范围内可替代591Ω等相近高精度电阻);
  2. 功率与电压:额定功率62.5mW(即1/16W),最大工作电压50V(实际应用需结合功率限制:当电压接近50V时,需确认负载电流是否在额定功率范围内);
  3. 温度系数:±100ppm/℃,表示温度每变化1℃,阻值漂移约0.059Ω;在-55℃~+155℃范围内,最大阻值漂移约12.4Ω,符合工业级电路温漂要求。

三、环境适应性与可靠性

该电阻的工作温度范围覆盖**-55℃至+155℃**,远超民用级电阻(0~70℃),可适应户外设备、工业高温环境(如电机控制柜、高温传感器)等极端场景;
厚膜电阻采用丝网印刷+高温烧结工艺,抗冲击振动性能优异,适合车载、手持设备等易受振动的应用;同时,厚膜结构的长期稳定性较好,阻值漂移率低,可保证电路长期工作可靠性。

四、典型应用场景

  1. 消费电子:智能手机、无线耳机的信号滤波电路、电源管理模块的分压电阻;
  2. 工业控制:PLC输入输出接口、小型传感器(温度/压力)的信号调理电路;
  3. 通信设备:小型基站、路由器的射频前端辅助电路、电源滤波网络;
  4. 汽车电子:车载信息娱乐系统的信号电路(温温范围可满足部分车载场景,需确认汽车级认证);
  5. 医疗设备:小型监护仪的生理信号采集电路、便携式医疗设备的电源模块。

五、产品优势

  1. 小封装高密度:0402封装尺寸仅1.0mm×0.5mm,可有效节省PCB空间,提升电路集成度;
  2. 稳定电性能:±1%精度与±100ppm/℃温系,温度变化及长期使用中阻值波动小,保证电路性能稳定;
  3. 宽温可靠:-55~155℃工作温度范围,覆盖多数极端环境,无需额外降额;
  4. 品牌质量:RALEC(旺诠)为全球知名电阻制造商,产品一致性好,符合RoHS环保标准,工艺成熟;
  5. 工艺兼容:厚膜贴片结构适配自动化SMT贴装,生产效率高,降低制造端成本。

该型号凭借稳定的电性能、宽温适应性及小封装优势,成为消费电子、工业控制等领域常规电路设计的常用选择。

Electronic component sourcing availability dashboard with ESD-protected samples

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
