RC-02K6803FT 厚膜贴片电阻产品概述

一、产品核心定位与典型应用

RC-02K6803FT是风华高科(FH品牌)推出的0402封装厚膜贴片电阻,属于通用型精密电阻范畴,主打「小型化、高可靠性、成本效益平衡」三大核心优势,广泛适配对尺寸敏感、精度要求适中的电子设备。其典型应用场景包括:

  • 消费电子:智能手机主板信号分压网络、蓝牙耳机音频滤波电路、智能穿戴设备传感器调理;
  • 汽车电子:车身温度/压力传感器信号放大、车载中控低功耗限流电路;
  • 工业控制:PLC输入输出模块限流、小型电机驱动反馈网络;
  • 通信设备:微型基站射频匹配、光纤收发器偏置电阻。

二、关键电气参数详解

该电阻核心参数经严格标定,满足多数工程场景性能需求:

  1. 阻值与精度:标称阻值680kΩ(680×10³Ω),精度±1%,属于E96系列电阻(精度等级对应E96阻值编码),可稳定满足分压、反馈、限流等电路的精度要求,无需额外校准;
  2. 功率与电压:额定功率62.5mW(0.0625W),是0402封装电阻的标准功率等级;最大连续工作电压50V,实际使用需注意「电压²/阻值」的功率匹配(50V下功率≈3.68mW,远低于额定值,可安全工作);
  3. 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值漂移±100×10⁻⁶。以工作温度范围为例,-55℃→+155℃(温差210℃),阻值最大漂移±2.1%,满足工业级环境稳定性;
  4. 工作温度范围:-55℃~+155℃,覆盖极端环境(沙漠高温、寒带低温),适配汽车、工业等严苛场景。

三、封装与物理特性

RC-02K6803FT采用0402封装(英制:0.04″×0.02″,公制1005:1.0mm×0.5mm),是小型化电子设备的主流贴片封装,物理特点如下:

  • 厚膜工艺:在氧化铝陶瓷基片上印刷电阻浆料,经高温烧结而成,兼具成本优势与稳定性;
  • 表面贴装设计:两端电极采用镍/锡镀层,适配回流焊、波峰焊工艺,焊接兼容性强;
  • 尺寸紧凑:单颗仅占1mm×0.5mm PCB面积,可大幅提升电路密度,适合智能手表、蓝牙耳机等高密度集成设备。

四、环境适应性与可靠性

该电阻经风华高科可靠性测试,满足以下要求:

  • 耐环境性能:符合RoHS无铅标准,抗潮湿(85℃/85%RH湿热测试1000小时后,阻值变化≤1%),抗机械应力(10g/50-2000Hz振动测试后性能稳定);
  • 长期可靠性:经过125℃/1000小时老化筛选,失效率≤0.1%/1000小时,保障设备长期稳定;
  • 兼容性:适配FR-4、陶瓷等多数PCB板材,焊接后无裂纹、阻值漂移问题。

五、选型与使用注意事项

为保障电路性能与电阻寿命,使用需注意:

  1. 功率降额:25℃时100%额定功率,70℃降额至80%,125℃降额至50%,155℃降额至25%(15.6mW),需根据实际温度调整;
  2. 电压限制:最大连续电压50V,脉冲电压需参考 datasheet(1ms内脉冲电压可提升至100V,但需控制脉冲功率);
  3. 焊接工艺:回流焊峰值≤260℃(持续≤10秒),波峰焊≤245℃(持续≤5秒),避免过热导致浆料老化;
  4. 存储条件:常温干燥(≤30℃/≤60%RH),开封后12个月内使用,避免受潮影响焊接。

六、品牌与质量保障

RC-02K6803FT由风华高科(FH品牌) 生产,风华高科是国内电子元器件龙头,拥有30余年厚膜电阻研发经验,产品符合GB/T 2693-2001、IEC 60115等标准,批量供应稳定,可提供样品支持、技术咨询,是众多厂商的首选供应商。

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
