FRC1206F49R9TS 厚膜贴片电阻产品概述

一、产品定位与核心价值

FRC1206F49R9TS是富捷电子(FOJAN)推出的工业级通用厚膜贴片电阻,针对中小功率、高稳定性、小体积的电路设计需求,平衡了精度、温区与成本,是消费电子、工业控制、通信等领域的高性价比解决方案。其核心价值体现在:以1206小封装实现250mW功率密度,宽温区(-55℃~155℃)覆盖极端环境,±1%精度满足常规电路一致性要求,适配自动化贴装生产。

二、关键参数详解

该电阻的核心参数直接决定应用场景适配性,具体如下:

  • 阻值与精度:固定阻值49.9Ω,误差±1%,可满足大部分电路的分压、限流、匹配需求(如电源反馈网络、信号调理电路),无需额外高精度成本;
  • 功率与电压:额定功率250mW,最大工作电压200V(注意:实际使用需降额——例如,电压接近200V时功率已远超额定值,需优先按功率/电流限制);
  • 温度特性:温度系数±100ppm/℃,即温度每变化100℃,阻值变化约±0.499Ω,在宽温区保持稳定,适合高低温交替场景;
  • 工作温区:-55℃+155℃,远超商业级(0℃70℃)与常规工业级(-40℃~125℃)标准,可应对设备内部高温或极端气候。

三、封装与结构特性

采用1206英制贴片封装(公制3216,尺寸≈3.2mm×1.6mm×0.5mm),适配常规SMT贴装设备,无引脚设计减少寄生电感/电容,适合高频电路(如射频匹配网络)。

结构基于厚膜工艺:以氧化铝陶瓷基片为载体,丝网印刷钌系厚膜电阻浆料,经高温烧结形成电阻层,再制备银钯合金电极、涂覆环氧树脂保护层,兼具耐磨损、抗腐蚀特性,长期可靠性高。

四、典型应用场景

结合参数特性,该电阻广泛适配以下场景:

  1. 工业控制:PLC信号调理电路、电机驱动限流电阻、传感器接口分压网络(需宽温稳定性);
  2. 消费电子:智能手机PMIC限流电阻、耳机/音箱音频匹配电阻(小体积需求);
  3. 通信设备:基站射频阻抗匹配、路由器电源滤波电路(高频适配);
  4. 汽车电子:车载中控信号调理电路(部分场景可覆盖,需注意整车认证);
  5. 医疗设备:小型监护仪传感器接口电路(宽温与可靠性需求)。

五、可靠性与使用注意事项

  1. 可靠性保障:通过MIL-STD-202冲击测试(抗1000G冲击)、振动测试(10G~2000Hz),表面保护层抵御潮湿/粉尘侵蚀;
  2. 降额建议:实际功率≤175mW(70%额定值),环境温度>85℃时每升高1℃降额0.33%,避免阻值漂移;
  3. 环保合规:符合RoHS 2.0、REACH标准,不含铅镉等有害物质,适配全球市场。

六、品牌与品质支持

FOJAN(富捷电子)专注被动元器件10余年,FRC1206系列通过ISO 9001认证,每批次进行阻值分选、温漂测试,确保一致性。批量客户可提供卷带编带定制、技术支持,供货周期7~15工作日。

该产品以实用性能为核心,覆盖多场景需求,是中小功率电路设计的可靠选择。

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
