RALEC旺诠RTT021960FTH厚膜贴片电阻产品概述

RTT021960FTH是台湾旺诠(RALEC)推出的一款0402封装厚膜贴片电阻,针对小功率精密电路场景设计,兼顾体积紧凑性、阻值精度与环境适应性,是工业控制、消费电子、通信设备等领域的实用选型。

一、产品核心身份与定位

作为旺诠厚膜电阻系列的一员,RTT021960FTH的型号标识清晰传递核心参数:

  • 前缀“RTT”对应旺诠厚膜贴片电阻常规系列;
  • “02”代表英制0402封装(公制1005,体积1.0mm×0.5mm);
  • “1960”表示阻值196Ω(末位“0”为精度码,对应±1%);
  • 后缀“FTH”体现厚膜工艺(Film Thick)与小功率特性。

该产品定位为低功耗精密厚膜电阻,适配对体积、精度有严格要求的高密度PCB设计。

二、关键性能参数解析

RTT021960FTH的参数设计精准匹配小功率精密应用需求:

  1. 阻值与精度:固定阻值196Ω,精度±1%——满足信号调理、阻抗匹配等场景对阻值一致性的要求,避免因偏差导致电路性能波动;
  2. 功率与电压:额定功率62.5mW,最大工作电压50V——低功耗电路中可安全承载连续电流(I≈0.255A),无需额外降额;
  3. 温度系数:±100ppm/℃——温度每变化1℃,阻值波动约0.0196Ω,宽温范围内漂移可控,适配户外/工业高温环境;
  4. 工作温度范围:-55℃~+155℃——覆盖工业级、汽车级(部分场景)温度要求,极端环境下稳定工作。

三、封装与工艺特性

  1. 0402封装优势:体积仅1.0mm×0.5mm,是小型化PCB的理想选择(如智能手环、蓝牙耳机主板);陶瓷基片散热性优于普通薄膜电阻;
  2. 厚膜工艺特点:采用丝网印刷+烧结工艺,在陶瓷基片上形成电阻膜层——相比薄膜电阻成本更低,抗脉冲、抗机械应力能力更强;膜层稳定性高,长期阻值漂移率<0.1%/1000小时。

四、典型应用场景

RTT021960FTH的参数特性适配多类场景:

  • 消费电子:蓝牙耳机音频链路阻抗匹配、智能手表电源分压取样;
  • 工业控制:传感器节点信号调理(温度/压力传感器放大)、PLC输入输出接口;
  • 通信设备:射频前端小信号滤波、基站辅助电路电压分压;
  • 汽车电子:胎压监测系统信号调理(需宽温适应性)。

例如,蓝牙耳机DAC输出端需196Ω电阻匹配耳机阻抗,该产品±1%精度保证音质一致性,0402封装适配主板紧凑空间。

五、可靠性与环保兼容性

  1. 可靠性验证:通过温度循环(-55℃~+155℃,1000次)、湿度测试(85℃/85%RH,1000小时),阻值变化率<0.5%,满足工业级要求;
  2. 环保合规:符合RoHS 2.0、REACH标准,不含铅、镉等有害物质,适配全球市场。

六、选型价值总结

RTT021960FTH的核心价值在于**“小体积+高精度+宽温适应性”的平衡**:

  • 相比同封装薄膜电阻,成本更低、抗脉冲能力更强;
  • 相比0603封装,体积缩小50%,适配高密度设计;
  • 旺诠供应链稳定,可提供批量供货保障。

对于小功率、精密阻值控制、宽温工作的电路,是高性价比选型方案。

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
