0201WMF7322TEE是UNI-ROYAL(厚声) 推出的通用型厚膜贴片电阻,核心定位为小体积、中等精度、宽温适应性的电路基础元件。其命名遵循行业通用规则,各部分含义清晰:
该产品的性能参数覆盖了通用电路的典型需求,关键指标如下:
标称阻值73.2kΩ,精度±1%,属于工业级常用精度范围。该精度可满足多数电路对阻值一致性的要求(如分压、滤波、信号调理等场景),无需额外校准即可实现稳定输出。
额定功率50mW,最大工作电压25V。通过功率-电压换算验证:
[ V^2/R = 25^2 / 73200 ≈ 0.0086W ]
远低于额定功率,说明电压承载能力充分,可覆盖低功耗电路的电压范围(如3.3V/5V供电系统)。
±200ppm/℃,即温度每变化1℃,阻值变化**±0.02%**。以实际应用场景为例:
-55℃~+155℃,覆盖工业级(-40+85℃)、汽车级(-40+125℃)的扩展需求,可适应极端环境下的稳定工作(如沙漠地区户外设备、汽车舱内高温场景)。
体积仅0.6mm×0.3mm×0.23mm(典型厚度),适合高密度PCB布局(如智能手机、智能穿戴设备的主板),可有效提升电路集成度,减少产品体积。
采用厚膜丝网印刷+高温烧结工艺,电阻膜层厚度约10~20μm:
该产品的参数特性与以下场景高度适配:
智能手机、蓝牙耳机、智能手环的信号调理电路(如麦克风偏置、射频信号滤波):利用0201小封装节省空间,满足便携设备的轻薄化需求。
PLC(可编程逻辑控制器)的输入输出模块、传感器信号放大电路:宽温(-55~+155℃)可适应工业现场的温度波动,±1%精度保证信号传输一致性。
机顶盒、智能音箱、路由器的电源分压电路、LED驱动电路:50mW功率满足低功耗需求,±1%精度保证电压调节稳定。
车载摄像头的信号滤波、车载温度传感器的校准电路:宽温覆盖汽车舱内/外的温度范围(-40~+125℃),厚膜工艺抗振动性能优异。
UNI-ROYAL(厚声)是国内电阻制造龙头企业,拥有20+年厚膜电阻生产经验,产品覆盖全球30+国家和地区:
综上,0201WMF7322TEE是一款兼顾小体积、可靠性与成本的通用厚膜贴片电阻,可广泛应用于便携、工业、消费电子等领域,是电路设计中分压、滤波、信号调理的理想选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
