RALEC RTT019762FTH 厚膜固定电阻器产品概述

一、产品定位与核心价值

RALEC(旺诠)RTT019762FTH是一款超小体积高精度厚膜固定电阻,针对高密度PCB设计场景(如可穿戴设备、智能手机、工业控制模块)优化,平衡了小封装、精度、功率与宽温适应性,适合中大规模批量应用。其核心价值在于:以0201超小封装实现±1%精度,同时覆盖-55℃~+125℃宽温范围,满足消费电子、工业、汽车电子等多领域的性能需求。

二、关键技术参数详解

该电阻器的参数设计精准匹配主流电子电路的应用需求,核心参数如下:

  • 阻值与精度:固定阻值97.6kΩ,±1%精度——可直接用于信号分压、偏置设置、滤波等场景,无需额外校准,减少电路设计复杂度;
  • 功率与电压:额定功率50mW(0201封装典型功率等级),最大工作电压25V——需注意70℃以上按降额曲线使用(如125℃时功率降额至30mW),避免过负荷损坏;
  • 温度稳定性:温度系数±200ppm/℃(温度每变化1℃,阻值变化±0.02%),工作温度范围-55℃~+125℃——宽温覆盖工业、汽车电子等 harsh 环境,长期运行阻值漂移可控;
  • 封装尺寸:0201英制封装(0.02×0.01英寸/0.6×0.3mm)——超小体积适配高密度PCB布局,有效缩小终端产品尺寸。

三、封装与工艺特点

  1. 0201超小封装:
    是目前消费电子、可穿戴设备的主流封装之一,支持0.4mm pitch的PCB布线,可显著提升电路集成度(如智能手机主板可增加30%以上元件密度)。

  2. 厚膜烧结工艺:
    旺诠采用成熟的丝网印刷+高温烧结技术,电阻膜层与陶瓷基底附着力强,抗电涌能力优于薄膜电阻,且成本控制合理,适合批量生产。膜层均匀性可保证阻值一致性,批量良率达99.5%以上。

四、典型应用场景

结合参数特性,该电阻器主要应用于以下场景:

  • 消费电子:智能手机射频信号调理电路(阻抗匹配)、平板音频模块偏置电阻、蓝牙耳机电源分压;
  • 可穿戴设备:智能手环/手表传感器接口电阻(如心率传感器信号滤波)、低功耗蓝牙模块偏置;
  • 工业控制:PLC模块低功耗电路、温度传感器信号分压(-55℃~+125℃宽温适配);
  • 汽车电子:车载仪表盘背光控制电路、胎压监测模块信号电阻(部分批次满足AEC-Q200汽车级认证);
  • 电源电路:小功率DC-DC转换器反馈分压、USB Type-C接口限流电阻。

五、可靠性与环境适应性

  1. 宽温可靠性:
    通过-55℃~+125℃ 1000次温度循环测试,阻值变化率≤±0.5%,满足工业级应用要求;
  2. 抗环境应力:
    • 抗湿性:85℃/85%RH环境下1000小时,阻值变化≤±1%;
    • 抗振动:10g~2000Hz振动测试(IEC 60068-2-6)无失效;
  3. 合规认证:
    符合RoHS 2.0、REACH环保标准,部分批次支持无卤要求。

六、应用注意事项

  1. 焊接规范:
    回流焊峰值温度≤260℃(持续≤10秒),手工焊温度≤350℃(持续≤3秒),避免封装开裂;
  2. 静电防护:
    虽厚膜电阻抗静电能力较强(人体模型≤2kV),但仍需遵循ESD防护规范,避免静电击穿;
  3. 降额使用:
    70℃以上环境需按功率降额(参考旺诠官方降额曲线),确保长期可靠性。

该电阻器凭借小体积、高精度、宽温适配的特点,成为高密度电子电路的优选元件,可有效降低终端产品的设计与制造成本。

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
