RTT026811FTH 厚膜贴片电阻产品概述

RTT026811FTH是台湾旺诠(RALEC)推出的一款小型化精密厚膜贴片电阻,采用0402封装(英制尺寸,对应公制1005),专为高密度、宽温环境下的电子电路设计,核心参数覆盖阻值、精度、功率等关键指标,适配多领域应用需求。

一、产品基本信息

  1. 品牌与型号:由RALEC(旺诠)生产,型号为RTT026811FTH,属于旺诠厚膜贴片电阻系列;
  2. 封装类型:0402封装,尺寸为1.0mm×0.5mm(公制),具备小型化、高集成度特点,适合紧凑电路板布局;
  3. 电阻类型:厚膜贴片电阻,通过丝网印刷电阻浆料、高温烧结等工艺制成,兼顾稳定性与成本优势。

二、核心电气参数解析

  1. 阻值与精度:标称阻值6.81kΩ,精度±1%,属于精密级电阻范畴,可满足电路中分压、限流、信号调理等对阻值精准度要求较高的场景,避免误差累积影响电路性能;
  2. 功率与电压:额定功率62.5mW,最大工作电压50V;实际应用需遵循降额原则(如环境温度超过25℃时,功率需按旺诠官方降额曲线调整),确保长期可靠性;
  3. 温度系数:±100ppm/℃,表示温度每变化1℃,阻值变化±0.01%;例如温度从-55℃升至155℃(变化210℃),阻值最大漂移±0.21%,能稳定适配宽温环境下的电路需求。

三、工作环境与可靠性

  1. 宽温工作范围:支持-55℃+155℃的工作温度区间,覆盖工业级(-40℃+125℃)与部分汽车级(-55℃~+150℃)应用场景,可应对极端温度下的稳定工作;
  2. 厚膜工艺可靠性:厚膜电阻膜层附着力强,抗冲击、抗振动性能优异,同时具备良好的耐湿性与耐老化性能,经旺诠严格的温度循环、湿热测试,可保证长期使用中阻值漂移在允许范围内;
  3. 环保合规:符合RoHS、REACH等国际环保标准,无铅无卤,适配绿色电子设计需求。

四、典型应用场景

  1. 消费电子:智能手机、平板电脑、智能穿戴设备的电源管理模块(BMS电压采样、电源分压)、信号调理电路(如音频放大、传感器信号滤波);
  2. 工业控制:PLC可编程逻辑控制器、工业传感器(温度、压力传感器)信号放大电路、电机驱动辅助电路,适配工业现场的宽温与振动环境;
  3. 汽车电子:车载辅助系统(胎压监测模块、中控小屏电路、倒车雷达信号处理),满足汽车低温启动(-55℃)与高温暴晒(+125℃)的工作要求;
  4. 通信设备:小型基站、路由器、交换机的射频前端偏置电路、数字电路中的限流电阻,适配高密度电路板布局。

五、品牌与工艺优势

  1. 旺诠技术积累:RALEC(旺诠)是全球知名的被动元件制造商,拥有超过30年的厚膜电阻研发与生产经验,产品广泛应用于汽车、工业、消费电子等领域;
  2. 精密制造工艺:采用高精度丝网印刷技术,确保阻值精度±1%的一致性;高温烧结工艺提升电阻膜层稳定性,减少长期漂移;
  3. 严格质量管控:每批次产品经过阻值分选、温度循环测试、湿热老化测试等多环节检测,符合IATF16949(汽车级)、ISO9001等质量管理体系要求,可靠性有保障。

总结:RTT026811FTH厚膜贴片电阻凭借小型化封装、精密阻值、宽温适应性与可靠性能,成为多领域电子电路设计的理想选择,适配高密度、宽温环境下的精准信号与功率控制需求。

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
