RC-02K1401FT 厚膜贴片电阻产品概述

一、产品基础识别信息

RC-02K1401FT是风华电子(FH) 推出的一款厚膜贴片电阻,属于0402封装系列。型号命名逻辑清晰:

  • “RC”代表厚膜电阻类型;
  • “02K”对应封装规格(英制0.04英寸×0.02英寸,公制1.0mm×0.5mm);
  • “1401”为阻值代码(140×10¹=1400Ω=1.4kΩ);
  • “FT”后缀明确精度(±1%)与温度系数(±100ppm/℃)。

二、核心电性能参数详解

这款电阻的关键参数经过风华严格测试,满足工业级与消费电子的常规需求:

  1. 阻值与精度:标称1.4kΩ,实际阻值范围1386Ω~1414Ω(±1%精度),无需额外校准即可适配大多数电路;
  2. 额定功率:25℃环境下额定功率62.5mW,低功耗设计适配便携式设备;
  3. 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值波动不超过**±0.14Ω**,宽温下稳定性可靠;
  4. 工作温区:-55℃~+155℃,覆盖工业车间、车载等极端温度场景。

三、封装与物理特性

0402封装是当前贴片电阻的主流小尺寸规格,RC-02K1401FT的物理细节如下:

  • 尺寸:长1.0±0.1mm、宽0.5±0.1mm、厚0.3±0.05mm;
  • 端电极:镍底层+无铅锡表层设计,兼容回流焊、激光焊等SMT工艺,焊接后可靠性高;
  • 重量:约0.005g,对便携设备的轻量化设计无额外负担。

四、典型应用场景

结合其小封装、宽温、高精度的特点,这款电阻适用于以下场景:

  1. 消费电子:智能手机、智能手环的传感器分压电路(如心率监测模块)、LED背光调节电阻;
  2. 工业控制:小型PLC的信号调理电路、温度传感器接口电阻(适配车间-20℃~60℃环境);
  3. 汽车电子:车载仪表盘背光电阻、低功耗胎压传感器辅助电路(需验证AEC-Q200时可联系风华升级);
  4. 通信设备:小型基站的射频滤波电路、路由器的电源分压电阻(小封装适配高密度PCB)。

五、产品优势与可靠性

  1. 小封装高密度:0402封装可在1cm²PCB上布局约2000个电阻,大幅节省空间;
  2. 宽温稳定:±100ppm/℃的TCR+宽温区,避免温度波动导致的电路漂移(如工业烤箱内的温度检测电路);
  3. 厚膜工艺可靠:丝网印刷+高温烧结的厚膜工艺,膜层附着力强,耐冲击、耐潮湿性能优于薄膜电阻;
  4. 成本可控:±1%精度属于常规高精度,相比±0.1%电阻成本降低30%以上,适合批量生产。

六、使用注意事项

为确保长期稳定运行,需注意以下细节:

  1. 功率降额:环境温度超25℃时需降额(如100℃时允许功率约50mW,155℃时约31mW),避免过热失效;
  2. 焊接工艺:回流焊峰值温度建议220~240℃(时间≤10s),波峰焊浸锡深度不超过封装高度2/3;
  3. 存储条件:未开封产品存于20±5℃、湿度40%~60%环境,开封后12个月内用完,避免端电极氧化;
  4. 静电防护:0402封装易受静电影响,生产中需佩戴静电手环,用静电袋存储。

RC-02K1401FT凭借成熟的厚膜工艺、小封装与宽温特性,成为消费电子、工业控制等领域的高性价比选择,适配多种常规电路的阻值匹配需求。

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
