0201WMF1303TEE是厚声电子(UNI-ROYAL) 推出的超小型厚膜贴片电阻,专为高密度PCB布局场景优化,核心参数清晰明确:
该电阻标称阻值130kΩ,采用四位数字代码标识(1303),前三位为有效数字(130),第四位为倍率(10³),阻值计算准确。±1%的精度等级在厚膜电阻中属于较高水平,满足多数中等精度电路需求(如分压、反馈、信号调理等),无需额外校准即可稳定工作。
额定功率50mW是最大允许功耗,需注意功率与电压的联动限制:根据公式 ( P = \frac{U^2}{R} ),当工作电压达到25V时,实际功耗约为 ( \frac{25^2}{130×10^3} ≈ 4.8mW ),远低于额定功率,因此实际使用需优先遵循电压限制(不超过25V),避免绝缘击穿。
温度系数±200ppm/℃表示:温度每变化1℃,阻值变化±200×10⁻⁶。以155℃为例,相对于25℃基准,阻值变化约3.38kΩ(仅描述温度漂移,与常温精度±1%不冲突)。-55℃至+155℃覆盖工业环境(-40℃+85℃)和部分汽车电子场景(-55℃+150℃),满足极端温度下的稳定工作。
0201是当前贴片电阻最小规格之一,体积仅0.02英寸×0.01英寸,适合便携电子、小型化模块(如智能手机传感器、智能穿戴)的高密度布局,可有效缩小PCB面积,降低整机体积。
采用厚膜丝网印刷工艺,在氧化铝陶瓷基片上印刷电阻浆料后烧结而成,优势显著:
因小型化、宽温、中等精度的特点,该电阻广泛应用于:
该产品平衡了小型化、精度、成本与宽温特性,是多数对尺寸敏感且需中等精度电路设计的理想选择。

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.
