FRC0402F91R0TS 贴片厚膜电阻产品概述

FRC00402F91R0TS是富捷电子(FOJAN)推出的0402封装贴片厚膜电阻,专为高密度、小型化电子电路设计,兼具高精度、宽温适应性与低功耗特性,可满足消费电子、工业控制、汽车电子等多领域的通用电阻需求。

一、产品基本定位

该电阻属于厚膜工艺贴片电阻,核心定位为小型化通用型高精度电阻:

  • 采用0402超小封装,适配紧凑PCB布局;
  • 厚膜工艺平衡成本与性能,适合批量应用;
  • 覆盖宽温范围与合理功率等级,兼顾环境适应性与电路兼容性。

二、核心电气性能参数

FRC0402F91R0TS的关键电气参数经过严格测试,具体如下:

1. 阻值与精度

阻值标称91Ω,精度为**±1%**——相比普通±5%精度电阻,能更准确实现分压、限流、信号衰减等功能,适合对阻值误差敏感的电路(如模拟信号调理、基准电压电路)。

2. 功率与电压额定值

  • 额定功率:62.5mW(0402封装典型功率等级),满足小电流电路(如传感器信号链、LED驱动辅助电路)的功耗需求;
  • 额定工作电压:50V(远高于实际使用电压,安全裕量充足),实际最大电流约26mA(由P=I²R计算),可避免过压损坏。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃——表示温度每变化1℃,阻值变化±0.0091Ω(91Ω×100ppm),稳定性优于普通碳膜电阻,适合温度波动较大的环境;
  • 工作温度范围:-55℃~+155℃——覆盖工业级宽温要求,可在极端环境(如低温户外、高温设备内部)稳定工作。

三、封装与物理特性

1. 封装规格

采用0402封装(英制:0.04英寸×0.02英寸,公制:1.0mm×0.5mm),为表面贴装器件(SMD),适配自动化SMT生产线,大幅提升生产效率;同时超小尺寸支持PCB高密度布局,符合便携式设备小型化趋势。

2. 工艺特点

厚膜工艺通过丝网印刷电阻浆料+高温烧结制成,具有以下优势:

  • 耐温性好,可承受SMT回流焊高温(230℃~260℃);
  • 阻值一致性高,批量生产稳定性强;
  • 成本低于金属膜/金属箔电阻,适合中低端通用场景。

四、典型应用场景

FRC0402F91R0TS的参数特性使其适用于多领域:

  1. 消费电子:手机、智能手表、平板的信号调理电路(如音频滤波、触控感应);
  2. 工业控制:PLC模块、传感器接口电路(宽温适应工业现场);
  3. 汽车电子:仪表盘背光驱动、传感器信号处理(部分车内环境温度符合-55~155℃);
  4. 医疗电子:小型医疗设备(如血糖仪、血压计)的低功耗电路;
  5. 通信设备:路由器、交换机的高速信号链路辅助电阻。

五、品牌与可靠性说明

富捷电子(FOJAN)作为国内专业电子元器件制造商,FRC0402F91R0TS具备以下可靠性保障:

  • 符合RoHS2.0环保标准,无铅无镉,适配绿色制造;
  • 经过IPC-A-610电子组装标准测试,焊接兼容性好;
  • 厚膜工艺保证长期使用阻值漂移小(≤0.5%/1000小时),寿命可靠;
  • 额定参数有充足裕量(如电压50V远高于实际工作值),降低失效风险。

六、选型与使用注意事项

为确保电阻性能稳定,使用时需注意:

  1. 避免过载:持续工作功率不超过62.5mW,电压不超过50V,否则会导致阻值漂移甚至烧毁;
  2. 焊接规范:采用回流焊时,温度需控制在260℃以内(峰值),避免局部过热;
  3. 存储环境:存储于常温(15℃~35℃)、干燥(相对湿度≤60%)环境,避免潮湿影响焊接;
  4. 精度匹配:若需更高精度(如±0.1%)或更低温度系数(如±50ppm/℃),需选择金属膜/箔电阻;
  5. 静电防护:贴片电阻为静电敏感器件,操作时需佩戴防静电手环/手套。

综上,FRC0402F91R0TS是一款高性价比的0402封装厚膜电阻,兼具小型化、高精度、宽温适应性,可满足多领域通用电路的电阻需求。

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.
