RTT024872FTH 厚膜贴片电阻产品概述

一、产品基本信息

RTT024872FTH是旺诠(RALEC) 推出的一款0402封装厚膜贴片电阻,属于旺诠常规厚膜电阻系列,专为低功耗、高密度PCB设计场景打造。型号中,“02”对应0402封装规格(英制尺寸:0.04英寸×0.02英寸,公制约1.0mm×0.5mm),“4872”代表核心阻值48.7kΩ,产品符合RoHS环保标准,可满足多数电子设备的通用电阻需求。

二、核心电气参数详解

该电阻的关键参数覆盖了常规电子电路的核心需求,具体如下:

  • 阻值与精度:48.7kΩ ±1%。±1%的精度属于工业级通用精度,可满足信号调理、分压、限流等电路对阻值偏差的要求,无需额外校准即可稳定工作。
  • 功率额定值:1/16W(62.5mW)。作为0402封装的小功率电阻,适合低功耗电路(如手机、智能穿戴的电源管理模块),避免功率过载风险。
  • 工作电压:50V(最大直流/交流电压)。该电压额定值可覆盖多数低压电路(如5V、12V、24V系统),超出需降额使用。
  • 温度系数(TCR):±100ppm/℃。表示环境温度每变化1℃,阻值变化±0.01%,若温度从-55℃升至155℃(温差210℃),阻值最大变化±2.1%,极端场景下仍能保持基本稳定。
  • 工作温度范围:-55℃~+155℃。宽温设计可适配工业控制、汽车电子(部分场景)、户外设备等高低温环境,无需额外温控措施。

三、产品设计与工艺优势

  1. 厚膜工艺稳定性:采用丝网印刷+高温烧结工艺制造,电阻膜附着力强,抗冲击振动能力优于薄膜电阻,适合有机械应力的场景(如车载设备)。
  2. 小体积高密度:0402封装体积仅约1.0mm×0.5mm,可大幅节省PCB空间,支持高密度布局(如智能手机主板、服务器模块)。
  3. 成本与性能平衡:相比高精度薄膜电阻,厚膜工艺成本更低,同时满足±1%精度与宽温需求,适合大规模量产应用。
  4. 耐环境性:表面涂覆防护层,可抵抗潮湿、灰尘等环境影响,延长产品寿命。

四、典型应用场景

RTT024872FTH的参数特性使其适用于多领域:

  • 消费电子:手机、平板、智能手表的电源滤波、信号分压电路,满足低功耗与小体积需求。
  • 工业控制:PLC模块、传感器信号放大电路(如温度、压力传感器),宽温设计适配车间高低温环境。
  • 汽车电子:车载显示屏背光控制、车载音响信号调理电路(符合部分汽车级温区要求)。
  • 通信设备:路由器、基站的射频/中频电路,高密度布局支持多通道信号处理。
  • 医疗设备:小型医疗仪器(如血糖仪、血压计)的电路模块,稳定性能保障设备精度。

五、选型与使用注意事项

  1. 功率降额:实际工作功率建议不超过额定值的50%(即≤31.25mW),避免长期满功率工作导致电阻老化加速。
  2. 焊接要求:采用SMT回流焊时,需遵循0402封装的回流曲线(峰值温度≤260℃,时间≤10秒),避免过热损坏电阻膜。
  3. 存储条件:未焊接产品需存储在常温(15~35℃)、干燥(湿度≤60%)环境中,避免长期暴露在高湿度下导致引脚氧化。
  4. 精度匹配:若应用场景需更高精度(如±0.1%),需更换薄膜电阻,但该产品的±1%已覆盖90%以上常规场景。

六、质量与认证

旺诠作为全球知名电阻制造商,RTT024872FTH符合RoHS 2.0(无铅环保)、REACH(有害物质限制)标准,部分批次可提供工业级可靠性测试报告(如温度循环、振动测试),满足客户对质量的要求。

该产品凭借平衡的性能、成本与可靠性,成为电子设计中48.7kΩ±1%阻值的优选通用电阻之一。

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
