FH RC-02K5110FT 厚膜贴片电阻产品概述

一、产品核心身份与定位

FH RC-02K5110FT是风华电子(FH) 推出的小型化厚膜贴片电阻,采用0402(英制)/1005(公制)封装,聚焦体积紧凑性、精度稳定性、宽温适应性三大核心,适配消费电子、工业控制、汽车电子等多场景的信号调理与小功率控制需求,是高密度PCB设计中常用的标准化电阻器件。

二、关键参数详解

该产品的核心参数与应用场景精准匹配,具体如下:

  1. 阻值与精度:标称阻值511Ω,精度等级±1%,符合工业级电阻的常规精度要求,可直接用于分压、限流、信号匹配等电路,无需额外校准;
  2. 功率能力:额定功率62.5mW(即1/16W),与0402封装的功率容量完全匹配,长期额定功率工作下无明显阻值漂移;
  3. 温度系数(TCR):±100ppm/℃,表示每变化1℃,阻值变化量为标称值的0.01%。以25℃为基准,155℃极端温度下阻值最大变化约6.64Ω,仍在±1%精度范围内,保证宽温性能稳定;
  4. 工作温度范围:-55℃~+155℃,覆盖户外低温、车载高温等极端环境,无需筛选宽温器件即可适配多场景。

三、封装与工艺特性

  1. 封装规格:0402封装(尺寸约1.0mm×0.5mm×0.35mm),是贴片电阻中体积较小的封装之一,可提升PCB集成密度60%以上,适合手机、可穿戴设备等便携产品;
  2. 厚膜工艺:采用钌基厚膜电阻浆料+氧化铝陶瓷基板,经丝网印刷、高温烧结制成。厚膜工艺兼具成本优势与抗脉冲能力,优于薄膜电阻,适合小功率信号/功率电路;
  3. 端电极设计:无铅环保(镍 barrier层+纯锡镀层),符合RoHS标准,适配回流焊、波峰焊等主流工艺,焊接后抗剪切强度≥10N,机械可靠性强。

四、典型应用场景

  1. 消费电子:手机/平板的电源管理(DC-DC反馈分压、电池保护限流)、可穿戴设备的传感器信号调理;
  2. 工业控制:PLC输入输出模块的信号分压、传感器放大电路偏置电阻、工业电源过流检测;
  3. 汽车电子:车载小功率传感器(温度/压力)信号调理、车载娱乐音频电路(适配-40℃~85℃车载环境);
  4. 通信设备:路由器/基站射频前端小信号电路、电源模块滤波电阻。

五、可靠性与环境适应性

  1. 长期稳定性:老化后阻值漂移率≤0.5%(典型值),满足设备5年以上工作周期要求;
  2. 环境测试:通过85℃/85%RH湿度循环(1000h)、-55℃~155℃温度冲击(500次),符合IEC 60115电阻标准;
  3. 机械性能:封装抗振动能力强,可承受设备运输中的轻微振动,无脱焊风险。

六、选型价值与优势

  1. 空间效率:0402封装比0603体积减小60%,助力产品小型化;
  2. 成本平衡:1%精度+100ppm/℃组合,比0.1%精度电阻成本降低30%,适合批量应用;
  3. 品牌保障:风华电子为国内电阻龙头,产品一致性好,供货周期稳定;
  4. 宽温适配:无需额外筛选宽温器件,简化采购与设计流程。

该产品以“小型化+高性价比+宽温稳定”为核心,是中低端电子设备信号/功率电路的优选电阻之一。

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
