FRC0402F4703TS 厚膜贴片电阻产品概述

FRC0402F4703TS是富捷电子(FOJAN)推出的一款小体积高密度厚膜贴片电阻,专为低功耗、紧凑电路设计,兼顾性能稳定性与成本优势,广泛适配消费电子、工业控制等多领域应用需求。

一、产品核心定位与价值

该电阻以**“小封装承载稳定性能”**为核心设计目标,解决了传统大封装电阻在手机、物联网终端等紧凑设备中的布局限制问题。同时,厚膜工艺的成熟应用,让其在批量生产一致性、成本控制上优于薄膜电阻,适合中低精度需求的量产场景。

二、关键电气参数深度解析

1. 阻值与精度

阻值为470kΩ(标识“4703”:前两位“47”为有效数字,第三位“0”为倍率10³,即47×10³=470000Ω),精度达**±1%**——这一精度满足90%以上工业级、消费级电路的阻值稳定需求,避免因偏差导致的信号失真或功能异常。

2. 功率与电压能力

  • 额定功率:62.5mW(0.0625W),适配低功耗电路(如传感器信号调理、小型单片机外围);
  • 最大工作电压:50V,需控制电路电压峰值不超过此值,避免电阻击穿或性能衰减。

3. 温度特性

  • 温度系数:±100ppm/℃——温度每变化1℃,阻值变化±100×10⁻⁶(约0.01%/100℃),宽温环境下仍能保证电路稳定;
  • 工作温度范围:-55℃~+155℃,覆盖工业户外、车载低温及高温作业场景。

三、封装与工艺优势

1. 0402封装特性

采用行业最小规格之一的0402封装(尺寸约1.0mm×0.5mm×0.3mm),可显著提升电路板集成度,适合智能手机、智能穿戴等对空间要求严苛的产品。

2. 厚膜工艺核心优势

以氧化铝陶瓷为基底,通过丝网印刷+高温烧结形成电阻膜层:

  • 热稳定性优于塑料基底,支持宽温工作;
  • 膜层厚度10~100μm,耐磨损、耐腐蚀性强,长期阻值漂移小;
  • 生产成本低于薄膜电阻,适合大规模量产。

四、典型应用场景

  1. 消费电子:智能手机传感器接口(加速度计、陀螺仪分压)、射频匹配网络;
  2. 工业控制:小型PLC、物联网终端的信号调理、限流保护电路;
  3. 汽车电子:车载仪表盘背光、胎压监测模块的信号放大(适配-40℃~+85℃环境);
  4. 通信设备:路由器、小型基站的偏置电路、滤波网络;
  5. 医疗设备:便携式监护仪的信号放大电路(低功耗、宽温需求)。

五、可靠性与品质保障

FOJAN对该产品的可靠性测试覆盖:

  • 温度循环(-55℃~+155℃,500次):阻值变化≤0.3%;
  • 功率负载(额定功率1000小时):阻值变化≤0.5%;
  • 耐湿性(85℃/85%RH,1000小时):阻值变化≤1%;
  • 符合RoHS 2.0、REACH标准,无铅无卤。

批量生产一致性管控严格,每批次电阻的阻值偏差、温度系数均在规格范围内,适合OEM/ODM量产需求。

该产品以“小体积、高稳定、低成本”为核心竞争力,是紧凑电路设计中替代传统电阻的优选方案。

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
