FH RC-01W2400FT 厚膜贴片电阻产品概述

一、产品基本属性与型号解析

FH RC-01W2400FT是风华高科(FH)推出的0201封装厚膜贴片电阻,属于常规精度(±1%)、低功率(50mW)系列产品,定位为消费电子与小型工业设备的基础阻性元件。型号字符含义明确:

  • RC:风华厚膜贴片电阻系列标识;
  • 01W:额定功率0.05W(50mW)的简化标注;
  • 2400:阻值编码(前三位240+倍率10⁰),即标称阻值240Ω;
  • FT:精度等级(±1%)与0201封装的组合标识。

二、核心性能参数深度解析

1. 阻值与精度

标称阻值240Ω,精度±1%,实际阻值范围为237.6Ω~242.4Ω。此精度可满足非超精密场景需求,如信号分压、简单限流、基准电压辅助调节等,无需额外校准即可实现稳定电路功能。

2. 功率与电压联动限制

  • 额定功率50mW(25℃环境下长期连续工作的最大功率);
  • 额定工作电压25V,但需注意功率约束:实际工作电压需满足 ( V \leq \sqrt{P_{额定} \times R} ),代入得 ( V \leq \sqrt{0.05 \times 240} \approx 3.46V )。若仅依赖25V额定值,易因过热导致电阻失效,实际应用需优先考虑功率降额。

3. 温度系数与温漂范围

温度系数(TCR)±200ppm/℃,即温度每变化1℃,阻值变化±0.048Ω。结合工作温度范围(-55℃~+125℃),最大阻值漂移量为±8.64Ω(占总阻值±3.6%),适合温度变化不极端或对阻值漂移要求不苛刻的场景(如普通LED驱动、音频耦合电阻)。

三、封装与典型应用场景

1. 0201封装特性

英制0201封装(公制0.6mm×0.3mm),体积极小,适配高密度贴片组装(如手机主板、蓝牙耳机、可穿戴设备)。其窄引脚间距、小焊盘面积,需注意焊接工艺精准性(如回流焊温度曲线需符合风华规范)。

2. 典型应用场景

  • 消费电子:手机信号分压电阻、蓝牙耳机充电限流电阻、智能手环传感器辅助电阻;
  • 小型工业设备:微型PLC接口电阻、小型电源模块反馈电阻;
  • 车载电子:低功耗车载传感器(如胎压监测)辅助电路电阻(适配-40℃~+85℃常规车载温区)。

四、环境适应性与可靠性

1. 宽温工作能力

-55℃~+125℃工作范围,覆盖工业级与消费电子极端温区:

  • 低温场景:稳定工作于北方户外设备、低温存储设备;
  • 高温场景:适配小型电源模块(内部温升可达100℃)长期工作。

2. 厚膜工艺优势

采用丝网印刷+烧结工艺,相比薄膜电阻成本更低,且耐机械应力、耐湿热性能更优。风华作为国内老牌厂商,该产品通过高温存储、温度循环、湿度测试等常规可靠性验证,满足量产稳定性需求。

五、选型与使用注意事项

  1. 功率降额:建议实际工作功率不超过额定值的50%(25mW),延长寿命避免过热;
  2. 焊接规范:0201封装需回流焊,焊接温度控制在230℃~250℃(峰值),时间≤10s,避免虚焊;
  3. 精度匹配:若需更高精度(如±0.1%),需换用风华高精度系列;
  4. 静电防护:贴片电阻为静电敏感元件,生产中需佩戴静电手环。

总结

FH RC-01W2400FT是一款性价比突出的常规厚膜贴片电阻,兼顾小体积、宽温适应性与基本精度,适合消费电子、小型工业设备等低功率、非超精密场景。风华品牌的可靠性保障,使其成为批量生产的优选元件之一。

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
