RC-02K3482FT 厚膜贴片电阻产品概述

一、产品基本属性

RC-02K3482FT是风华电子(FH品牌)推出的超小型厚膜贴片电阻,型号命名遵循行业通用规则:

  • “RC”标识厚膜贴片电阻类型;
  • “02”对应封装尺寸(0402英制);
  • “K3482”表示阻值34.8kΩ(“K”为倍率,3482即34.8×10²Ω);
  • “FT”明确精度(±1%)与功率(62.5mW)等级。

该产品采用0402封装(英制尺寸:0.04英寸×0.02英寸,约1.0mm×0.5mm),核心定位为“高密度、低功耗电路的经济型电阻解决方案”。

二、核心性能参数

RC-02K3482FT的参数覆盖工业级通用需求,关键指标如下:

  1. 阻值与精度:标称阻值34.8kΩ,精度±1%(实际阻值范围34.452kΩ~35.148kΩ),满足信号调理、分压电路的基础精度要求;
  2. 功率等级:25℃环境下额定功率62.5mW,是0402封装厚膜电阻的典型规格,适配低功耗应用场景;
  3. 温度系数:±100ppm/℃(温度每变1℃,阻值变化±3.48Ω),在50℃温度波动内,阻值漂移≤0.174kΩ,稳定性适中;
  4. 工作温度范围:-55℃~+155℃,覆盖工业级低温环境(如户外设备)及部分高温工况(如车载非发动机舱电路)。

三、封装与工艺特点

  1. 0402封装优势:
    超小型尺寸大幅节省PCB空间,适合智能手机、可穿戴设备等对体积要求严格的产品;表面贴装设计兼容回流焊、波峰焊,生产效率高。

  2. 厚膜工艺特性:
    采用丝网印刷+高温烧结工艺制备电阻膜层,膜层厚度较薄膜电阻更厚,具备更好的抗过载能力(短时间过载功率可达额定值2~3倍);同时厚膜工艺成本低于薄膜电阻,性价比优势明显。

  3. 环保兼容性:
    符合RoHS2.0、REACH环保标准,无铅焊接兼容,满足全球市场环保要求。

四、典型应用场景

RC-02K3482FT因“小型化、低功耗、中等精度”的特点,广泛应用于以下领域:

  1. 消费电子:智能手机音频调理、平板电脑电源分压、可穿戴设备传感器偏置电路;
  2. 工业控制:小型PLC I/O模块限流、传感器信号放大反馈、工业仪表校准电路;
  3. 通信设备:路由器/交换机电源滤波、基站射频前端低功率匹配网络;
  4. 汽车电子:车载中控按键电路、仪表盘背光分压(工作温度适配车载环境);
  5. 医疗设备:便携式监护仪信号处理、小型血糖仪校准电阻。

五、可靠性与使用注意事项

  1. 可靠性表现:
    厚膜工艺赋予其较好的长期稳定性(125℃高温老化1000小时,阻值漂移≤0.1%);抗机械应力能力强,可适应柔性PCB弯曲变形(如可穿戴设备)。

  2. 功率降额要求:
    环境温度超过25℃时需降额使用(如100℃时额定功率降至约30mW),避免过热失效。

  3. ESD防护:
    耐受能力±2kV(人体模型),满足一般电路需求;高ESD场景需额外增加防护措施。

总结

RC-02K3482FT是一款平衡成本与性能的厚膜贴片电阻,在小型化、精度、功率之间实现了实用化匹配,可覆盖消费电子、工业控制、通信等多领域的低功耗高密度设计需求,是风华电子成熟的电阻产品之一。

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
