RC-01W2201FT 贴片厚膜电阻产品概述

一、产品核心身份与规格定位

RC-01W2201FT是风华电子(FH) 推出的通用型0201封装贴片厚膜电阻,属于小功率电阻范畴。型号中:

  • “RC”为风华贴片厚膜电阻系列标识;
  • “2201”对应阻值编码(22×10¹=2200Ω=2.2kΩ);
  • “FT”代表±1%精度与厚膜工艺组合。
    该产品以小体积、稳定性能为核心特点,适配高密度PCB设计与常规工业/消费电子场景。

二、关键电气性能参数解析

1. 阻值与精度

标称阻值2.2kΩ,精度±1%——属于通用级精度,可满足多数模拟电路(如信号分压、偏置电路)的阻值一致性需求,避免因精度偏差导致电路参数漂移。

2. 额定功率

50mW(0.05W)——0201封装的典型功率规格,实际应用需遵循60%降额原则(建议实际功率≤30mW),延长产品寿命并降低过热风险。

3. 额定工作电压

25V(峰值电压)——为电阻两端最大允许电压,若电路电压波动较大,需结合功率降额进一步限制(如30mW时最大电压约17.3V),防止击穿损坏。

4. 温度系数(TCR)

±200ppm/℃——厚膜电阻的常规温度系数,意味着温度每变化1℃,阻值漂移±200Ω/10⁶Ω(2.2kΩ电阻在125℃时漂移约±44Ω),满足工业级温度范围的基本稳定性要求。

三、物理封装与工艺特性

1. 封装尺寸

0201英制封装(公制0.6mm×0.3mm)——贴片电阻中尺寸较小的规格之一,适合高密度PCB布局(如智能手机、可穿戴设备主板),有效节省电路板空间。

2. 厚膜工艺

采用丝网印刷+高温烧结工艺:电阻膜层与氧化铝陶瓷基底结合牢固,成本可控、批量一致性好,适合大规模工业生产。

3. 焊接兼容性

兼容无铅焊接工艺(峰值温度260℃/10秒),焊盘设计符合IPC标准,适配常规回流焊、波峰焊设备,降低生产工艺难度。

四、环境适应性与可靠性

1. 工作温度范围

-55℃+125℃——覆盖工业级温度要求(-40℃+85℃为商业级),可应用于低温环境(北方户外设备、车载冬季工况)与高温环境(电子设备内部散热区)。

2. 环境耐受性

表面覆盖环氧树脂保护层,具备:

  • 抗潮湿(相对湿度95%以下);
  • 抗盐雾(符合JESD22-A101标准);
  • 抗机械振动(10g~2000Hz)能力,满足常规室内外环境需求。

3. 寿命可靠性

额定参数下MTBF(平均无故障时间)达10⁶小时以上,可支撑多数电子设备的生命周期(如消费电子3~5年、工业设备10年以上)。

五、典型应用场景

  1. 消费电子:智能手机、平板的音频分压、传感器偏置电路(利用小体积实现紧凑布局);
  2. 工业控制:PLC接口电路、传感器信号放大(适配-55℃~+125℃工业环境);
  3. 车载电子:倒车雷达、胎压监测的低功率电路(抗低温性能适配车载工况);
  4. 通信设备:小型基站、路由器的射频偏置、数字电路限流(高密度封装适配设备小型化)。

六、品牌与选型参考

1. 品牌优势

风华电子(FH)是国内被动元件龙头,产品通过ISO9001、RoHS、REACH认证,产能稳定,供货周期可控,适合批量采购需求。

2. 选型注意事项

  • 功率降额:实际功率≤30mW(避免长期过载);
  • 电压降额:实际电压≤18V(70%降额,防止击穿);
  • 精度匹配:若需更高精度(如±0.1%),需选择精密厚膜/薄膜电阻(本产品仅满足通用精度);
  • 焊接管控:无铅焊接需控制峰值温度与时间,避免损伤电阻膜层。

该产品凭借小体积、稳定性能与工业级适应性,成为通用电子电路中2.2kΩ/±1%小功率电阻的优选方案。

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
