RC-02K3922FT 厚膜贴片电阻产品概述

RC-02K3922FT是风华电子(FH)推出的0402封装高精度厚膜贴片电阻,专为高密度PCB设计场景优化,兼顾性能稳定性与成本控制,广泛覆盖消费电子、汽车电子、工业控制等领域的常规电路需求。

一、产品基本属性

  1. 封装与技术路线:采用0402英寸(约1.0mm×0.5mm)小型贴片封装,基于厚膜电阻工艺——通过丝网印刷电阻浆料烧结于陶瓷基底,兼具成本优势与环境适应性。
  2. 品牌与标识:由国内被动元件龙头风华电子(FH)生产,产品表面印字为3922(四位代码),遵循贴片电阻行业规范:前三位为有效数字(392),第四位为倍率(10²),对应实际阻值39.2kΩ。
  3. 系列定位:属于风华常规高精度贴片电阻系列,产品一致性符合GB/T 2693-2001(固定电阻器)标准。

二、核心性能参数

RC-02K3922FT的关键参数经严格测试,满足中高精度电路设计需求:

  1. 阻值与精度:标称阻值39.2kΩ,精度±1%,即实际阻值范围为39.2kΩ±392Ω,可支撑信号调理、分压电路等对阻值偏差敏感的场景。
  2. 功率与电压限制:额定功率1/16W(62.5mW),最大工作电压50V——实际使用需同时满足“功率≤62.5mW”与“电压≤50V”(例如50V下最大允许阻值≥40kΩ,需结合电路实际阻值确认安全区间)。
  3. 温度特性:温度系数(TCR)±100ppm/℃,即温度每变化1℃,阻值漂移±0.01%;工作温度范围-55℃~+155℃,覆盖工业级与汽车级宽温需求。
  4. 耐环境性能:抗振动(符合IEC 60068-2-6)、耐盐雾(符合IEC 60068-2-11),长期稳定性测试(1000小时高温老化)阻值变化率≤0.5%。

三、典型应用场景

RC-02K3922FT因小体积、高精度、宽温特性,适配以下场景:

  1. 消费电子:手机、平板、智能穿戴的信号滤波、分压电路(0402封装可压缩PCB面积,提升设备便携性)。
  2. 汽车电子:车载中控小功率控制电路、传感器信号调理(宽温范围满足车载环境-40℃~+85℃的波动需求)。
  3. 工业控制:小型PLC、传感器模块的偏置电路、限流电路(抗机械应力与湿度性能稳定)。
  4. 通信设备:基站射频前端偏置电阻、信号衰减电路(高密度PCB设计下的优选元件)。

四、工艺与可靠性优势

  1. 焊接兼容性:兼容回流焊、波峰焊工艺,焊接后抗振动脱落性能符合汽车电子MIL-STD-202标准。
  2. 成本控制:厚膜工艺相比薄膜电阻成本更低,适合批量应用场景。
  3. 库存与供应:风华电子产能稳定,该型号为常规料号,交货周期通常1~2周,可满足量产需求。

五、选型与替代参考

若需调整参数,可参考以下方案:

  1. 同系列替代:风华RC-02K3900FT(39kΩ±1%)、RC-02K4000FT(40kΩ±1%),参数接近但阻值略有差异。
  2. 同参数跨品牌:国巨(Yageo)0402 39.2kΩ±1% 1/16W电阻、三星(Samsung)0402 39.2kΩ±1% 1/16W电阻,性能相当但品牌不同。

总结:RC-02K3922FT是一款性价比突出的高精度小功率厚膜贴片电阻,0402封装适配高密度设计,宽温特性与稳定性能覆盖多领域需求,是电子设计中常规高精度电阻的优选之一。

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
