RC-02K1100FT 厚膜贴片电阻产品概述

一、产品基本定位与品牌背景

RC-02K1100FT是风华高科(FH品牌) 推出的一款小型化通用厚膜贴片电阻,主打紧凑封装与高性价比,适配各类对尺寸敏感的电子电路设计。风华高科作为国内被动元件领域的龙头企业,拥有30余年厚膜电阻生产经验,其产品以稳定的性能、可靠的质量覆盖消费电子、工业控制、汽车电子等多领域。该型号定位为精密型通用贴片电阻,兼顾成本与性能,是小型化电路设计的优选元件之一。

二、核心参数与性能指标

RC-02K1100FT的核心参数针对常规电路需求优化,关键指标如下:

  • 阻值与精度:标称阻值110Ω,精度±1%,满足大多数精密信号处理、分压/限流电路的精度要求,无需额外校准即可实现稳定的电路输出;
  • 功率额定值:62.5mW(即1/16W),对应0402封装的主流功率等级,实际应用需确保电路工作功率不超过额定值(建议留20%余量,避免长期过载);
  • 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化约0.011Ω(110Ω×100×10⁻⁶),温度波动100℃时阻值漂移约1.1Ω,仍在±1%精度范围内,适合常规温度场景;
  • 工作温度范围:-55℃+155℃,覆盖工业级温区(-40℃+85℃)及部分高温应用,低温性能满足户外或极端环境需求。

三、封装与物理特性

该型号采用0402封装(英制尺寸,对应公制1005:长1.0mm×宽0.5mm),是当前贴片电阻中尺寸最小的主流封装之一,可显著降低PCB布局面积,提升电路密度。厚膜工艺赋予其以下特性:

  • 耐机械应力能力较强,兼容常规SMT贴片机精度要求,适合自动化批量生产;
  • 表面采用无铅镀层(符合RoHS环保标准),焊接可靠性高,适配无铅焊接工艺;
  • 电阻体由厚膜浆料烧结而成,长期使用阻值漂移小,稳定性优于部分薄膜电阻。

四、典型应用场景

RC-02K1100FT因尺寸小、性能均衡,广泛应用于:

  1. 消费电子:手机、平板、智能手表的电源管理模块(限流电阻)、信号调理电路(分压电阻);
  2. 物联网(IoT)设备:传感器节点(温湿度、加速度传感器)的信号滤波与偏置电路;
  3. 工业控制:小型PLC、变频器的辅助控制电路(低功率信号分压);
  4. 汽车电子:车载信息娱乐系统、传感器接口电路(辅助电路,需确认整车温区需求);
  5. 医疗设备:小型监测仪器(血氧仪、体温计)的电路限流与信号放大。

五、可靠性与环境适应性

风华高科对该型号的可靠性设计体现在:

  • 高低温循环测试:-55℃~+155℃循环500次,阻值变化率≤0.5%;
  • 湿热测试:40℃/93%RH环境下1000小时,阻值变化率≤1%;
  • 抗过流能力:短时间过流(额定电流1.5倍)下无开路或阻值突变,满足电路异常工况保护需求。

六、选型与替换参考

6.1 选型注意事项

  • 功率余量:实际功率需满足 ( P=I^2R \leq 62.5mW ),计算得最大允许电流约23.8mA,建议实际应用≤18mA(留25%余量);
  • 温度场景:若电路温度波动超过100℃,需评估阻值漂移对精度的影响(如精密测量电路需更高TCR的电阻)。

6.2 替代型号

同参数替代型号包括:

  • 国巨(Yageo):RC0402JR-07110RL;
  • 三星(Samsung):CL0402-JP-110RL;
  • 风华同系列:RC-02K1100FT(不同批次)。

需注意:不同品牌封装公差略有差异,贴装前需确认贴片机参数。

该型号以平衡的性能与紧凑的尺寸,成为小型化电路设计中“成本-性能”的优选方案,广泛适配各类常规电子设备的需求。

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
