该产品为0201封装小功率厚膜贴片电阻,以紧凑体积、通用精度和宽温适应性为核心,适配高密度PCB设计场景,广泛覆盖以下领域:
标称阻值1.2kΩ(1200Ω),精度±5%,满足大多数通用电路的误差要求(如电源分压、信号衰减),无需高精度(1%/0.1%)的场景下性价比突出。
±200ppm/℃,表示温度每变化1℃,阻值变化±200×10⁻⁶×标称值。以1.2kΩ为例,温度从25℃升至125℃(变化100℃)时,阻值变化±24Ω(1176Ω~1224Ω),满足一般温度波动下的电路稳定性。
-55℃+155℃,覆盖工业级(-40125℃)和部分汽车级(-55~150℃)场景,适合极端环境下的长期稳定工作。
采用氧化铝陶瓷基板+钌基电阻浆料,通过丝网印刷、高温烧结形成电阻层,相比薄膜电阻:
端电极采用Ni底层+Sn镀层(无铅环保),抗氧化性能好,焊接强度高,避免虚焊、脱焊问题,提升组装可靠性。
产品经过严格可靠性测试,符合国际标准(JIS C 5201、IEC 61041):
UNI-ROYAL(厚声)为国内领先被动元件厂商,0201WMJ0122TEE具备:
该产品以「小体积、宽温、高可靠性」为核心优势,是高密度、低功耗电路设计的优选通用电阻。

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.
