FH RC-02K182JT 贴片厚膜电阻产品概述

一、产品定位与核心属性

FH RC-02K182JT是风华电子(FH)推出的一款小型化通用型贴片厚膜电阻,主打“尺寸紧凑、性能均衡、成本可控”,适配自动化表面贴装生产线,是消费电子、工业控制、汽车电子等领域的基础被动元件。其核心设计围绕0402封装展开,兼顾低功耗场景的功率需求与宽温环境的稳定性,可满足多数电路的分压、限流、信号匹配等基础功能,无需额外校准即可支撑常规电路运行。

二、关键电气参数深度解析

该电阻的参数设计针对性强,覆盖常规电路的核心需求:

  1. 阻值与精度:标称阻值1.8kΩ(标识代码“182”,即18×10²Ω),精度±5%,属于常规精度等级,适配非精密测量、普通信号处理等场景(如音频放大偏置、电源分压检测)。
  2. 功率与电压:额定功率62.5mW,最大工作电压50V。需注意功率-电压匹配:当电压接近50V时,最大工作电流为1.25mA(I=P/U=62.5mW/50V),实际应用中需避免超过该阈值,以防电阻过热损坏。
  3. 温度特性:温度系数±100ppm/℃(每℃阻值变化0.01%),工作温度范围-55℃~+155℃。宽温下阻值漂移可控(温差210℃时变化约2.1%),可支撑极端环境(如车载高温、工业低温)下的稳定运行。

三、封装与物理特性

  1. 封装尺寸:采用0402封装(英制尺寸,对应公制1005),尺寸约1.0mm×0.5mm,是小型化电子设备的首选,可有效降低PCB板占用面积,提升电路集成度(如手机主板、智能穿戴设备)。
  2. 制造工艺:基于厚膜工艺——在氧化铝陶瓷基片上丝网印刷电阻浆料,经高温烧结形成致密电阻膜,再涂覆保护漆。该工艺兼顾了“性能稳定”与“成本可控”,抗机械冲击能力优于薄膜电阻,耐潮性强于碳膜电阻。
  3. 贴装适配:表面贴装设计完全适配自动化贴装设备,生产效率高,适合批量应用(如家电、通信设备的大规模生产)。

四、典型应用场景

FH RC-02K182JT的参数特性使其覆盖多领域:

  1. 消费电子:手机/平板的电源管理电路(分压检测、限流保护)、音频信号调理电路(如耳机接口偏置);
  2. 工业控制:小型PLC的输入输出接口、传感器信号预处理(如应变片放大前的偏置电阻);
  3. 汽车电子:低端车载设备(仪表盘辅助电路、车载充电器限流),宽温范围满足车内高温(夏季暴晒)需求;
  4. 通信设备:小型路由器/无线AP的射频辅助电路(低功耗信号匹配)、电源滤波电路;
  5. 医疗设备:小型监护仪的心率/血氧信号处理电路,符合宽温与可靠性要求。

五、可靠性与环境适应性

  1. 厚膜工艺优势:陶瓷基片耐温性强,电阻膜与基片结合牢固,抗振动/冲击能力优于薄膜电阻;表面保护漆隔绝潮气与化学腐蚀,长期使用性能稳定。
  2. 宽温稳定性:-55℃+155℃的温度范围覆盖工业级(-40+85℃)与部分汽车级(-55~+125℃)需求,低温下无阻值漂移,高温下无过热衰减。
  3. 标准合规:符合IEC 60115-1电子电阻标准,批量产品一致性好,参数偏差极小。

六、品牌与品质保障

FH(风华)是国内被动元件龙头企业,拥有数十年研发生产经验,产品覆盖全球30+国家。RC-02K182JT作为其成熟产品线,具备:

  1. 稳定供应链:年产能充足,交货周期短(常规订单7~15天);
  2. 环保认证:通过RoHS、REACH认证,符合欧盟环保要求;
  3. 品质管控:每批产品经100%参数测试,部分批次支持AEC-Q200汽车级认证,降低客户生产风险。

综上,FH RC-02K182JT是一款“小尺寸、高性能、高性价比”的通用贴片电阻,可满足多数电子设备的基础电阻需求,是工程师选型的可靠选择。

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
