0201WMF1332TEE是UNI-ROYAL(厚声)推出的0201封装厚膜贴片电阻,针对高密度、宽温环境下的精密信号电路设计,兼顾小型化与稳定性,属于工业级通用精密电阻范畴。其标识含义清晰:
该产品定位覆盖消费电子、汽车电子、工业控制等多领域的小型化电路需求,是对体积、精度、环境适应性有综合要求的优选器件。
标称阻值13.3kΩ,精度±1%——这一等级可满足绝大多数中高端电路的信号调理、分压/分流需求,无需额外校准即可实现稳定的电路参数一致性,适用于传感器信号放大、基准电压生成等对阻值偏差敏感的模拟电路。
额定功率50mW(即1/20W),最大工作电压25V——功率规格适配小信号处理电路(如微控制器I/O口驱动、低功耗传感器电路),电压上限覆盖常见低压直流系统(3.3V、5V、12V等),避免过压击穿风险。
温度系数(TCR)±200ppm/℃,工作温度范围-55℃+155℃——TCR数值意味着温度每变化1℃,阻值变化不超过0.02%;宽温范围可稳定工作于汽车发动机舱(-40℃125℃)、工业高温环境(如光伏逆变器内部)等极端场景。
0201封装是目前小型化贴片电阻的主流规格之一,可显著降低PCB布局空间,适配智能手机、智能穿戴、小型通信模块等对体积要求严苛的产品。
该电阻采用厚膜丝网印刷工艺制造,核心结构包括:
工艺优势在于:成本可控(适合量产)、耐环境性强(玻璃釉防护)、温度稳定性好(陶瓷基片与浆料匹配性佳)。
结合参数与工艺特点,该电阻主要适配以下场景:
车载传感器信号调理电路(如胎压监测TPMS、水温传感器)——宽温范围覆盖汽车发动机舱与低温环境,±1%精度确保传感器信号采集准确。
PLC输入输出模块、小型仪器仪表(如温度变送器)——50mW功率适配低功耗电路,25V电压覆盖工业低压系统。
智能穿戴设备(智能手环、蓝牙耳机)、小型智能家居终端——0201封装实现高密度布局,满足产品小型化设计需求。
小型基站模块、无线耳机蓝牙模块——稳定的温度特性保障信号传输一致性,避免温度变化导致的电路性能波动。

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.
