RC-02K9091FT 厚膜贴片电阻产品概述

一、产品基本信息与型号解析

RC-02K9091FT是风华电子(FH) 推出的厚膜贴片电阻,属于该品牌常规高精度贴片电阻系列。型号各部分含义清晰:

  • “RC”为风华电阻产品系列标识,覆盖主流厚膜贴片电阻型号;
  • “02”对应封装规格为0402(英制代码,实际尺寸约1.0mm×0.5mm),是小型化电子设备的主流封装;
  • “K9091”代表标称阻值9.09kΩ(“K”为kΩ单位,“9091”为阻值数字编码,属于分压、比例电路常用的非标准阻值);
  • “FT”关联核心性能:精度±1%、温度系数±100ppm/℃。

该产品采用厚膜工艺制造,兼顾成本与性能,适用于多场景批量应用。

二、核心电气性能参数

参数项 规格值 关键说明 标称阻值 9.09kΩ 非标准阻值,适配分压电路 精度等级 ±1% 工业级常规精度,无需额外校准 额定功率 62.5mW(连续) 0402封装功率上限,支撑低功耗电路 额定工作电压 50V(DC/AC峰值) 过压可能导致击穿,需严格控制 温度系数(TCR) ±100ppm/℃ 温度每变1℃,阻值变化≤0.01%

注:功率与电压需同时满足(如9.09kΩ电阻在50V下的功率为50²/9090≈274mW,远大于额定功率,实际使用需按功率降额)。

三、封装工艺与物理特性

1. 封装规格

0402封装尺寸紧凑(约1.0mm×0.5mm×0.4mm),可显著节省PCB布局空间,适配便携式设备、小型模块的高密度集成需求。

2. 厚膜工艺优势

采用丝网印刷+高温烧结工艺:

  • 电阻浆料(钌基)印制于陶瓷基片,烧结后形成稳定电阻膜;
  • 激光微调实现精度控制,一致性好;
  • 成本低于薄膜电阻,适合大规模量产;
  • 电阻膜附着力强,耐磨损、抗环境腐蚀。

四、环境适应性与温度稳定性

1. 宽温工作范围

  • 温度区间:-55℃~+155℃,覆盖工业级(-40℃+85℃)与部分汽车级(-55℃+125℃)场景,可适应户外IoT节点、高温电源模块等环境。

2. 温度稳定性验证

±100ppm/℃的TCR在厚膜电阻中属中等偏优:

  • 示例:25℃→125℃(温差100℃),阻值变化量=9.09kΩ×100ppm×100℃≈91Ω,相对变化率仅1%,满足多数常规电路的稳定性要求。

3. 耐环境性能

符合IEC 60068-2-67(恒定湿热)标准,在40℃、93%RH环境下仍能保持电气性能稳定,适配潮湿地区或户外设备。

五、典型应用场景

RC-02K9091FT因小封装、高精度与宽温特性,主要应用于:

  1. 便携式消费电子:智能手机、智能手表、蓝牙耳机的电源分压、音频滤波、射频匹配电路;
  2. IoT传感器节点:温湿度传感器、运动传感器的信号调理,蓝牙/ZigBee模块的偏置电阻;
  3. 工业控制子系统:小型PLC、电机驱动辅助电路的限流、分压元件;
  4. 汽车电子辅助:车载充电器、后视镜控制器的内部电阻(需确认汽车级认证,风华部分型号可满足)。

⚠️ 注意:额定功率62.5mW,不适用于高功率电路(如功率放大、电源输出端),仅适合信号级/低功耗场景。

六、品牌可靠性与品质保障

风华电子(FH)是国内被动元件龙头企业,RC-02K9091FT具备:

  • 环保认证:符合RoHS、REACH标准,无铅无镉;
  • 质量体系:遵循ISO 9001,批量产品一致性好;
  • 售后支持:提供技术咨询与定制化方案(如阻值微调、特殊封装)。

该产品经多项可靠性测试(如温度循环、振动),可支撑客户大规模量产需求。

综上,RC-02K9091FT是一款高性价比、小体积、宽温稳定的厚膜贴片电阻,适配多数小型化电子设备的常规电路设计。

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
