FRC0204F1431TS 厚膜贴片电阻产品概述

一、产品基本定义

FRC0204F1431TS是富捷电子(FOJAN)推出的一款小型化厚膜贴片电阻,采用0402封装(英制尺寸0.04英寸×0.02英寸,公制约1.0mm×0.5mm),专为高密度PCB设计场景打造。作为电子电路中最基础的被动元件之一,该电阻主要承担信号调节、分压、限流、负载匹配等核心功能,广泛适配消费电子、工业控制、可穿戴设备等多领域的电路需求,以高稳定性、小体积和成本优势成为批量应用的优选方案。

二、核心参数详解

该电阻的关键参数明确且适配主流应用需求,具体如下:

  1. 阻值与精度:标称阻值1.43kΩ(即1430Ω),精度±1%——采用四位代码标识(1431),前三位为有效数值(143),第四位为倍率(10¹),精度满足大多数电路对阻值一致性的要求,无需额外校准;
  2. 功率与电压:额定功率62.5mW(对应1/16W),最大工作电压50V——功率参数适配小电流、低功耗电路,实际应用中建议按70%降额使用(实际功率≤43.75mW),可进一步提升长期可靠性;
  3. 温度特性:温度系数±100ppm/℃——指温度每变化1℃,阻值变化±100×10⁻⁶,例如从25℃升至125℃(变化100℃),阻值漂移≤±1%,与精度指标匹配,宽温下性能稳定;
  4. 工作温度范围:-55℃~+155℃——覆盖工业级环境的温度波动,可满足户外设备、车载辅助电路等场景的耐温需求。

三、封装与工艺特点

  1. 封装规格:0402封装是贴片电阻中体积较小的规格之一,适合高密度PCB设计(如智能手机主板、可穿戴设备模块),可有效节省电路空间,提升PCB集成度;
  2. 厚膜工艺:采用陶瓷基底+丝网印刷电阻膜+高温烧结工艺制备——相比薄膜电阻成本更低,相比绕线电阻体积缩小90%以上,同时具备良好的耐温性和稳定性;
  3. 端电极结构:三层金属电极(镍层+铜层+锡层)——保证焊接兼容性(支持回流焊、波峰焊),焊接后附着力强,可耐受多次温度循环,避免虚焊、脱落问题。

四、典型应用场景

结合参数与工艺特点,该电阻的核心应用场景包括:

  1. 消费电子:智能手机、平板电脑的电源管理模块(电池充放电限流、电压分压)、音频电路(信号衰减);
  2. 可穿戴设备:智能手环、手表的传感器信号调理电路(如心率传感器的前置分压),小体积适配设备轻薄化需求;
  3. 工业控制:小型PLC、温度传感器模块的信号处理电路(宽温范围满足车间环境波动);
  4. 通信设备:小型基站、路由器的射频前端辅助电路(高密度PCB设计需小体积元件);
  5. 汽车电子:车载中控的辅助电路(如USB充电口的限流),-55℃~125℃场景下性能稳定。

五、可靠性与环境适应性

  1. 温度稳定性:±100ppm/℃的温度系数在宽温范围内阻值漂移可控,避免因温度变化导致电路参数偏移;
  2. 耐环境测试:通过高低温循环(-55℃~+155℃,循环100次)、湿热测试(85℃/85%RH,1000h)等可靠性测试,符合工业级标准;
  3. 功率降额优势:额定功率62.5mW留有充足余量,实际应用中降额使用可降低热应力,延长产品寿命;
  4. 绝缘性能:最大工作电压50V,绝缘电阻≥1GΩ(100V测试),避免电压击穿风险。

六、品牌与质量保障

FOJAN(富捷)作为国内专注被动元件的制造商,该产品具备以下优势:

  1. 认证齐全:通过ISO9001质量管理体系认证、RoHS环保认证,符合欧盟无铅要求;
  2. 批量一致性:每批次产品经过100%阻值分选、精度测试,确保批量应用中参数一致;
  3. 售后支持:提供技术文档、焊接工艺指导,对批量订单提供样品测试服务。

该电阻凭借小型化、高稳定性和成本优势,成为各类电子设备中基础电路的可靠选择,适配多场景的量产需求。

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.

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
