0402WGF1213TCE是UNI-ROYAL(厚声)推出的小封装高精度厚膜贴片电阻,针对小型化、高集成度电子设备设计,兼顾性能稳定性与成本控制,属于工业级基础被动元件。其核心特点为0402超小封装、±1%高精度、宽温工作范围,适配多种中低功率场景的电路需求,无需额外校准即可满足多数信号调理、分压等功能。
标称阻值为121kΩ(阻值代码“1213”,即121×10³Ω),精度等级±1%,可满足多数电路对阻值一致性的要求。例如在分压电路中,该电阻与同精度电阻搭配时,输出电压偏差可控制在±1%以内,无需后续校准。
温度系数为**±100ppm/℃**,即温度每变化1℃,阻值变化±12.1Ω(121kΩ×100e-6)。该指标可适应-55℃~+155℃的宽温环境,阻值漂移在工业级应用中可接受。
采用0402标准贴片封装,尺寸为1.0mm(长)×0.5mm(宽)×0.35mm(典型厚度),符合IPC-J-STD-001标准,具备以下优势:
工作温度范围**-55℃~+155℃**,可覆盖汽车电子(发动机舱模块)、工业控制(户外传感器节点)等高低温场景,无需额外散热或温度补偿。
采用厚膜印刷技术制造,电阻膜层稳定性优于薄膜电阻:
符合RoHS 2.0、REACH等环保指令,焊端为无铅设计,适配绿色制造需求。
UNI-ROYAL(厚声)是国内知名被动元件制造商,拥有20余年电阻生产经验,产品广泛应用于消费电子、汽车、工业等领域。0402WGF1213TCE通过以下品质管控:
该产品凭借小封装、高精度、宽温特性,成为中低端电子设备中替代进口电阻的高性价比选择,适用于对成本敏感且需稳定性能的场景。

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.
