RC-02K3161FT 厚膜贴片电阻产品概述

RC-02K3161FT是风华(FH)品牌推出的一款0402封装厚膜贴片电阻,针对小型化、宽温环境下的电子电路设计,具备稳定的电气性能与可靠的环境适应性,广泛应用于消费电子、工业控制等领域。

一、产品基本信息

RC-02K3161FT属于风华被动元件产品线中的通用厚膜贴片电阻,型号命名遵循行业标准:其中“02K”对应0402封装(英制尺寸0.04英寸×0.02英寸,公制约1.0mm×0.5mm),“3161”表示标称阻值3.16kΩ(前三位316为有效数字,第四位1为倍率10¹),“FT”为风华产品系列代码。产品采用厚膜工艺制造,通过丝网印刷、烧结等工序形成电阻膜层,兼顾成本与性能优势。

二、核心性能参数详解

1. 阻值与精度

标称阻值为3.16kΩ,精度等级±1%,即在25℃标准环境下,实际阻值与标称值偏差不超过±31.6Ω,满足多数对阻值精度要求稳定的电路需求(如分压、限流、信号滤波)。

2. 功率特性

额定功率62.5mW,指环境温度≤+70℃时可长期稳定工作;若温度升高需按降额曲线使用(如+125℃时降额至约20mW),避免过热失效。

3. 温度系数

温度系数(TCR)±100ppm/℃,表示每变化1℃,阻值变化为标称值的百万分之一(±0.01%/℃)。例如,温度从25℃升至125℃(变化100℃),阻值变化约±3.16Ω(±0.1%),宽温环境下稳定性优异。

4. 工作温度范围

覆盖**-55℃~+155℃**,符合工业级、部分汽车级应用的温度要求,可在极端高低温环境长期运行(如北方户外设备、高温工业现场)。

三、典型应用场景

RC-02K3161FT的小型化封装与宽温性能,适用于以下场景:

  • 消费电子:智能手机、智能手表、蓝牙耳机的信号调理电路(传感器分压、音频滤波);
  • 工业控制:小型PLC、传感器信号采集模块的限流电阻、基准电压分压电路;
  • 汽车电子:车载仪表盘背光、胎压监测传感器接口电路(辅助小功率信号传输);
  • 通信设备:小型基站、路由器的射频辅助电路(匹配网络电阻元件)。

四、风华品牌与可靠性保障

风华作为国内被动元件龙头,RC-02K3161FT通过以下措施保障可靠性:

  1. 工艺管控:高精度丝网印刷与烧结,电阻膜层均匀,阻值一致性高;
  2. 环保认证:符合RoHS 2.0、REACH标准,无铅无镉,满足出口要求;
  3. 可靠性测试:经过高温老化(155℃×1000h)、温湿度循环(-55℃+155℃×500次)、机械振动(102000Hz×2g),阻值变化率≤0.5%。

五、选型与使用注意事项

  1. 功率降额:环境温度超+70℃时,按风华官网降额曲线调整功率;
  2. 焊接工艺:采用回流焊(预热150180℃×60120s,峰值230245℃×3060s),避免手工焊接热损伤;
  3. 静电防护:ESD等级≥2kV,操作需佩戴防静电手环、使用防静电工具;
  4. 存储条件:25±5℃、湿度40%~60%环境存储,未开封保质期2年,开封后尽快使用。

RC-02K3161FT凭借小型化、宽温稳定、成本可控的特点,成为小型电子电路替代插件电阻的理想选择,适用于对尺寸、温度适应性有要求的各类场景。

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
