0201WMF4993TEE厚膜贴片电阻产品概述

一、产品定位与核心身份

0201WMF4993TEE是厚声电子(UNI-ROYAL)推出的0201封装厚膜贴片电阻,属于小功率高精度电阻范畴,专为高密度PCB布局、小信号电路设计需求打造——兼顾稳定性与成本优势,广泛适配消费电子、工业控制等多领域应用,是中小批量电子设计的实用选型。

二、基础参数与规格明细

该电阻核心参数清晰明确,关键指标可直接支撑电路设计选型:

  • 阻值:499kΩ(贴片代码标识为“4993”,前两位“49”为有效数字,第三位“3”表示×10³);
  • 精度:±1%(满足常规电路对阻值一致性的要求,无需额外校准);
  • 功率等级:50mW(0.05W,适用于小电流、低功耗场景,避免过载风险);
  • 工作电压:25V(最大额定工作电压,选型时需结合电路实际电压范围);
  • 温度系数:±200ppm/℃(阻值随温度变化的稳定性,满足一般环境下的性能需求);
  • 工作温度范围:-55℃~+155℃(宽温区设计,可适应工业低温、车载高温等极端场景);
  • 类型:厚膜贴片电阻(采用厚膜丝网印刷工艺制备,工艺成熟、可靠性高)。

三、封装与物理特性

采用标准0201贴片封装(英制尺寸:0.02inch×0.01inch,公制对应0.6mm×0.3mm),物理尺寸小巧且符合行业规范:

  • 长度:0.6±0.03mm;
  • 宽度:0.3±0.03mm;
  • 厚度:0.23±0.03mm(典型值)。
    该封装可有效缩小电路模块体积,适配便携设备(如智能手表)、小型化电子系统(如无线耳机模块)的高密度布局需求。

四、性能表现与可靠性

厚膜工艺赋予该电阻稳定的性能表现,核心优势体现在:

  1. 温度稳定性:工作温度覆盖-55℃至+155℃,阻值变化控制在±200ppm/℃以内,避免因温度波动导致电路性能偏移(如传感器偏置电压漂移);
  2. 功率承载能力:50mW功率等级满足小信号电路(如运算放大器偏置、传感器信号调理)的功耗需求,长期工作无过热风险;
  3. 抗干扰性:厚膜电阻的结构设计使其具备一定的抗电磁干扰能力,适合复杂电路环境(如工业控制模块);
  4. 可靠性验证:产品经过高温老化(155℃×1000h)、温度循环(-55℃~+155℃×500次)、湿度测试(85℃/85%RH×1000h)等验证,符合IEC 61000等行业标准,长期使用稳定性可靠。

五、典型应用场景

0201WMF4993TEE因小巧封装与稳定性能,广泛应用于以下场景:

  1. 消费电子:智能手机、智能手表的加速度计/陀螺仪偏置电路、无线充电模块辅助电阻;
  2. 工业控制:小型PLC输入输出模块、温度传感器(PT100)信号放大电路;
  3. 汽车电子:车载胎压监测(TPMS)传感器接口电路、座舱温度传感器辅助电阻;
  4. 通信设备:小型基站射频前端滤波电路、无线耳机蓝牙模块信号调理;
  5. 医疗电子:血糖仪、血压计的信号放大偏置电路、小型监护仪传感器接口。

六、品牌与品质保障

厚声电子(UNI-ROYAL)是国内电阻行业知名厂商,产品符合RoHS 2.0、REACH等环保法规要求,批量供货稳定(月产能可达千万级)。该电阻从原材料(陶瓷基板、厚膜浆料)采购到生产流程(丝网印刷、烧结、激光调阻)均严格管控,可满足电子厂商的量产需求,同时提供免费样品测试与技术选型支持。

该产品是0201封装小功率电阻的实用选型,平衡了精度、稳定性与成本,适合大多数常规电子设计的需求。

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
