FRC1206F4993TS 厚膜贴片电阻产品概述

FRC1206F4993TS是FOJAN(富捷)推出的一款1206封装厚膜贴片电阻,针对电子电路中常规阻抗匹配、分压、限流等基础应用场景设计,兼顾性能稳定性与生产适配性,适用于消费电子、工业控制、通信等多领域。

一、产品基本定位与核心属性

该电阻属于常规功率型厚膜贴片电阻,采用厚膜工艺制造(丝网印刷+高温烧结),具备成本可控、可靠性稳定的特点。其核心定位是满足中小功率电路的基础阻抗需求,无需特殊封装或高精度要求的场景,是电子设计中常用的“通用型”被动元件之一。

二、关键性能参数详细解析

1. 阻值与精度

  • 标称阻值:499kΩ(对应代码“4993”,即499×10³Ω);
  • 精度等级:±1%(属于商业级偏优精度,可满足大多数电路对阻值一致性的要求,比如分压电路中避免因阻值偏差导致输出误差过大)。

2. 功率与电压额定值

  • 额定功率:250mW(连续工作时的最大功率限制,实际使用需结合电路电压计算,避免过功率);
  • 最大工作电压:200V(直流或交流峰值电压上限,实际电压需同时满足功率约束,例如200V下该电阻功耗约80mW,远低于额定功率,可安全工作)。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃(温度每变化1℃,阻值变化±0.01%;若环境温差210℃(-55℃→155℃),阻值总变化约±2.1%,符合厚膜电阻的常规温度特性);
  • 工作温度范围:-55℃~+155℃(覆盖工业级低温(-55℃)与高温(155℃)场景,可满足户外设备、高温工业环境的使用需求)。

三、封装与物理特性

该电阻采用1206英制封装(对应公制3216:3.2mm×1.6mm),是贴片电阻的主流封装之一,适配大多数PCB设计:

  • 电极设计符合IPC标准,表面镀锡或镀镍,易于SMT自动贴装与回流焊;
  • 厚膜工艺的膜层附着牢固,抗机械应力(如振动、冲击)能力优于薄膜电阻,适合批量生产中的运输与焊接环节。

四、典型应用场景

结合参数特性,该电阻适用于以下场景:

  1. 消费电子:智能家居(如温湿度传感器电路的分压)、小型家电(如LED指示灯限流)、手机周边配件(如充电器的电压检测);
  2. 工业控制:小型PLC的输入接口电路、传感器信号调理(如电流转电压电路的负载电阻);
  3. 通信设备:低功率射频电路的匹配网络(如蓝牙模块的阻抗匹配)、简单滤波电路(如RC低通滤波);
  4. 汽车电子(部分):非发动机舱的车载控制电路(如中控屏的背光驱动限流,需结合整车可靠性要求验证)。

五、可靠性与环境适应性

  1. 环境耐受性:工作温度范围覆盖高低温,可应对户外低温(如北方冬季)、高温车间(如注塑车间)等环境;
  2. 抗过流能力:厚膜电阻膜层较厚,瞬间过流(如脉冲电路)的耐受能力优于薄膜电阻,不易因突发电流损坏;
  3. 长期稳定性:经过老化测试(如1000小时高温老化),阻值漂移≤0.5%,可满足电子设备的长期使用需求。

六、品牌与品质保障

FOJAN(富捷)作为国内被动元件制造商,该产品符合RoHS 2.0、REACH等环保标准,无铅无卤;批量供货稳定,适合中小批量研发及大规模生产;产品出厂前经过全检,确保参数一致性与可靠性。

总结:FRC1206F4993TS是一款性价比突出的通用型厚膜贴片电阻,兼顾性能与成本,适用于多领域的常规电子电路设计,是电子工程师常用的基础元件之一。

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
