RTT024023FTH 厚膜贴片电阻产品概述

RTT024023FTH是台湾旺诠(RALEC)推出的一款0402封装厚膜贴片电阻,针对小功率高精度电路场景设计,兼具稳定性能与批量生产一致性,广泛适配消费电子、工业控制等多领域应用需求。

一、产品基本信息

RTT024023FTH属于旺诠常规厚膜电阻系列,采用成熟厚膜印刷工艺制造,核心定位为小体积、高精度、宽温稳定的贴片电阻器件。产品型号明确了核心属性:“0402”对应英制封装尺寸(约0.4mm×0.2mm),“402kΩ”为标称阻值,“±1%”为精度等级,直接指向信号调理、分压电路等对精度有要求的应用场景。

二、核心电气性能参数

RTT024023FTH的关键电气参数经过严格测试,可满足多数中低功耗电路的性能要求:

  • 阻值与精度:标称阻值402kΩ,精度±1%,能有效避免阻值偏差对信号电平、分压比的影响,适合模拟电路中需要稳定信号传输的场景;
  • 功率与电压:额定功率62.5mW,最大工作电压50V,可稳定承载小信号放大、滤波、匹配电路等场景的功率负载,避免过载损坏;
  • 温度特性:温度系数±100ppm/℃,在-55℃~+155℃的宽温范围内,阻值变化率控制在合理区间,适配工业高温环境、汽车电子低温启动等场景;
  • 工作温度范围:-55℃至+155℃,覆盖了多数户外、工业设备的环境温度波动,无需额外散热设计即可稳定工作。

三、封装与物理特性

  1. 封装尺寸:采用0402英制贴片封装,尺寸约0.4mm(长)×0.2mm(宽)×0.15mm(厚),体积小巧,可有效节省PCB板空间,适配高密度电路设计;
  2. 工艺特点:厚膜电阻工艺(印刷银浆、电阻浆、玻璃釉保护层),相比薄膜电阻成本更低,相比绕线电阻体积更小,兼具稳定性与经济性;
  3. 焊接兼容性:支持回流焊、波峰焊等常规贴片焊接工艺,焊接后焊点可靠性高,长期使用无虚焊风险,适合自动化生产线上的批量贴装。

四、典型应用场景

RTT024023FTH的参数特性使其适配多领域低功耗高精度电路:

  • 消费电子:手机、平板、智能穿戴设备的信号调理电路(如麦克风前置放大、传感器信号滤波),小体积满足设备轻薄化需求;
  • 工业控制:PLC模块、传感器接口电路的分压/限流电阻,宽温范围适配工业现场-20℃~+85℃的环境温度;
  • 汽车电子:车载中控、胎压监测系统的辅助电路,-55℃低温特性可满足北方冬季启动需求;
  • 通信设备:路由器、交换机的射频前端匹配电路,62.5mW功率满足小信号传输的功率要求。

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
