RTT0561R9FTP 厚膜贴片电阻产品概述

RTT0561R9FTP是台湾旺诠(RALEC)推出的一款0805封装厚膜贴片电阻,针对低功耗、中等精度需求的电子电路设计,兼顾小型化布局与环境适应性,广泛适配消费电子、工业控制、汽车电子等领域。

一、产品核心身份与定位

该型号属于旺诠厚膜电阻系列,型号编码解析:RTT为旺诠厚膜电阻系列代号,05对应封装尺寸(0805英制封装),61R9表示阻值61.9Ω,FTP为精度与性能等级(±1%精度)。产品定位为商用级高性价比贴片电阻,覆盖大多数常规电子系统的电阻需求,无需额外成本追求更高精度或功率。

二、关键电气与性能参数

  1. 阻值与精度:标称阻值61.9Ω,精度±1%——满足大多数电路对阻值一致性的要求(如分压、限流、信号匹配等场景,无需高精度激光调阻成本);
  2. 功率与电压:额定功率125mW(正常工作时的最大功率损耗),最大工作电压150V(需注意:实际工作中需遵循“P=V²/R”的功率限制,避免过压损坏);
  3. 温度特性:温度系数(TCR)±100ppm/℃——即环境温度每变化1℃,阻值相对变化±0.01%,若温度变化100℃,阻值变化±1%,可适配-55℃至+155℃的宽温环境;
  4. 工作温区:-55℃+155℃——覆盖工业级(-40℃+85℃)与部分汽车级(-55℃~+125℃)应用场景,极端温度下性能稳定。

三、封装与物理特性

  1. 封装规格:0805英制封装(对应公制2.0mm×1.25mm),无引线贴片式设计,适配自动化SMT贴装工艺,生产效率高;
  2. 物理参数:厚度约0.5mm(标准贴片电阻厚度),重量约0.01g,可满足高密度PCB布局(如手机、智能穿戴设备的紧凑电路);
  3. 环保认证:符合RoHS 2.0、REACH等国际环保标准,无铅焊接兼容,适配绿色电子产品设计。

四、典型应用场景

  1. 消费电子:手机、平板、智能手表的音频滤波电路、电源管理模块的分压电阻、LED指示灯限流电阻;
  2. 工业控制:PLC(可编程逻辑控制器)的模拟量输入电路、传感器信号调理电路、小型电机驱动的限流电阻;
  3. 汽车电子:仪表盘背光电路、车身控制模块(BCM)的低功耗信号电路、胎压监测系统(TPMS)的辅助电阻;
  4. 通信设备:路由器、交换机的电源滤波、信号匹配电路(低频率段)。

五、可靠性与质量保障

  1. 工艺优势:采用厚膜印刷+激光微调工艺,阻值一致性好,批量生产偏差控制在±1%以内;
  2. 环境可靠性:通过温度循环、湿度老化、振动冲击等测试(如-55℃~+155℃循环1000次,阻值变化≤0.5%);
  3. 品牌背书:旺诠(RALEC)是全球知名电阻制造商,产品通过ISO9001质量管理体系、IATF16949汽车行业质量体系认证,批量供货稳定性高。

六、选型注意事项

  1. 功率匹配:实际工作功率需≤125mW(如工作电流≤14.2mA,61.9Ω×(14.2mA)²≈125mW);
  2. 温度适配:若应用环境温度超过155℃,需更换更高温区的电阻(如薄膜电阻或功率电阻);
  3. 精度需求:若需±0.1%以上精度,需选择激光调阻的薄膜电阻,本型号仅适配中等精度场景。

总结:RTT0561R9FTP以“小封装、中等精度、宽温适配、高性价比”为核心优势,是常规电子电路设计中替代通用电阻的理想选择,尤其适合对空间、成本敏感且需宽温工作的场景。

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
