FRC1206F1R00TS 厚膜贴片电阻产品概述

一、产品定位与核心规格

FRC1206F1R00TS是富捷(FOJAN)推出的通用型厚膜贴片电阻,专为消费电子、工业控制等场景设计,核心参数清晰明确:

  • 阻值:1Ω ±1%
  • 额定功率:250mW
  • 最大工作电压:200V
  • 温度系数:±200ppm/℃
  • 工作温度范围:-55℃~+155℃
  • 封装:1206(英制尺寸,公制3.2mm×1.6mm)

二、关键性能参数深度解析

1. 阻值精度与长期稳定性

±1%的精度属于通用级精度范畴,相比±5%精度电阻,可显著提升电流采样、分压电路的信号准确性(如电池管理系统中电流检测误差可控制在1%以内)。
厚膜工艺采用陶瓷基片(氧化铝为主),阻值长期稳定性优异:老化1000小时后,阻值漂移通常≤0.5%,满足批量生产的一致性需求。

2. 功率与电压的双重限制

  • 功率额定值:250mW,对应1Ω阻值时,最大允许电流为$\sqrt{P/R}=\sqrt{0.25/1}=0.5A$;
  • 电压额定值:200V,需注意功率与电压的协同限制——当阻值较低时(如1Ω),功率限制起主导作用(若电压达200V,电流将达200A,远超功率承受能力),实际使用需优先保证$I^2R≤250mW$。

3. 宽温区适应性

温度系数±200ppm/℃表示:每变化1℃,阻值变化0.0002%。在工作温区-55℃+155℃内,最大阻值波动为:
$1Ω×(155-(-55))×200×10^{-6}=0.04Ω$
即阻值范围0.96Ω1.04Ω,无需额外温度补偿电路,可直接适配工业现场高低温环境。

三、封装与物理特性

1206封装是贴片电阻的主流通用封装,适配自动化贴装生产线(贴装效率≥10000片/小时),且具备:

  • 机械强度:陶瓷基片耐冲击、抗振动(符合IEC 60068-2-6振动测试标准);
  • 热传导:厚膜层与基片结合紧密,散热效率优于薄膜电阻,适合小功率高密度电路。

四、典型适用场景

1. 消费电子电源电路

  • 电池管理系统(BMS):作为电流采样电阻,精准检测手机、平板的充放电电流,±1%精度避免过流保护误动作;
  • 电源滤波:在DC-DC转换电路中作为限流电阻,稳定输出电压,降低纹波干扰。

2. 工业自动化控制

  • PLC模拟量模块:作为信号分压电阻,将传感器(如温度、压力传感器)的微弱信号按比例放大,宽温区满足-20℃~+60℃的工业现场需求;
  • 小型电机驱动:在步进电机控制电路中作为限流电阻,保护电机免受过流冲击。

3. 通信设备

  • 路由器/交换机电源:在DC-DC模块中作为电压调节电阻,200V工作电压适配中高压电源场景;
  • 信号匹配:在射频收发电路中作为阻抗匹配电阻,保证信号传输损耗≤0.1dB。

五、品牌与品质保障

富捷(FOJAN)是国内专注被动元件研发的老牌厂商,FRC1206F1R00TS具备:

  • 环保认证:符合RoHS 2.0、REACH标准,无铅无镉;
  • 质量体系:通过ISO 9001质量管理体系认证,每批次100%阻值测试;
  • 可靠性验证:经过高温老化(155℃×1000小时)、温循(-55℃~+155℃×500次)测试,失效率≤0.1%/1000小时。

六、选型与使用注意事项

  1. 功率降额:实际使用建议降额至70%以下(≤175mW),延长寿命2~3倍;
  2. 贴装工艺:回流焊峰值温度控制在230℃~250℃,时间≤60秒,避免高温损坏;
  3. 温区匹配:若场景温度超出-55℃+155℃(如汽车级-40℃+125℃),需更换车规级电阻;
  4. 绝缘要求:200V电压场景下,需保证PCB绝缘间距≥0.8mm,避免短路。

该产品以高性价比、稳定性能覆盖中低端电子电路需求,是消费电子、工业控制领域的主流选型之一。

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
