风华RC-02K40R2FT厚膜贴片电阻产品概述

一、产品基本定位与封装规格

RC-02K40R2FT是风华(FH)推出的0402封装厚膜贴片电阻,核心定位为小型化高密度电路的常规选型器件。0402封装(英制尺寸,对应公制1005,即长1.0mm×宽0.5mm)适配主流SMT贴装工艺,可兼容多数小型电子设备的PCB布局——例如智能手机、智能穿戴的紧凑电路设计。

厚膜工艺是其技术核心:通过丝网印刷电阻浆料于陶瓷基片、高温烧结成型,平衡了成本控制与电气稳定性,既适合大规模量产,又能满足工业/消费类场景的可靠性需求,避免薄膜电阻的高成本或线绕电阻的体积劣势。

二、核心电气性能参数

该电阻的关键指标精准匹配小型电路的功率与精度要求:

  • 阻值与精度:标称阻值40.2Ω,精度±1%——可覆盖多数模拟电路(信号分压、电流采样)的基本需求,无需额外校准;
  • 功率与电压:额定功率62.5mW(0402封装常规上限),最大连续工作电压50V;实际应用需遵循降额原则(25℃下建议工作功率≤41.7mW),避免热过载;
  • 温度系数:±100ppm/℃——温度变化对阻值的影响可量化:若环境温度从25℃升至100℃(升温75℃),阻值变化仅±0.3015Ω,波动仍在±1%以内,满足宽温区精度稳定。

三、环境适应性与可靠性

RC-02K40R2FT的环境耐受能力适配复杂场景:

  • 工作温区:-55℃+155℃——覆盖工业级(-40+85℃)及部分汽车级(-55~+125℃)范围,可应对高低温交替(如车载、户外工业设备);
  • 抗恶劣环境:厚膜工艺赋予其较好的抗湿度(符合IEC 60068-2-67湿负荷测试)与抗振动性能(可承受10G~20G振动频率),适合便携式/车载设备;
  • 长期可靠性:风华通过全流程管控(老化测试、阻值分选),确保失效率≤10^-6次/小时,支撑设备长期稳定运行。

四、典型应用场景

基于小型化、宽温区与精准度特点,该电阻广泛应用于:

  1. 消费电子:智能手机音频分压、智能穿戴电池保护模块的电流采样;
  2. 工业控制:小型PLC传感器接口的电阻网络、温度传感器信号放大分压;
  3. 汽车电子:胎压监测系统(TPMS)辅助电路(需确认项目温区需求);
  4. 通信设备:5G小基站、路由器射频前端的匹配电阻。

五、品牌与品质保障

风华(FH)是国内老牌电子元器件厂商,拥有30+年厚膜电阻研发经验,RC-02K40R2FT符合RoHS 2.0无铅环保、REACH标准,通过ISO 9001认证。供应链稳定可满足批量订单,同时提供参数选型、降额指导等技术支持,帮助客户优化电路设计。

该产品凭借平衡的性能与成本优势,成为小型化电路设计的高性价比选型。

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
