1210W2J0821T5E是UNI-ROYAL(厚声) 品牌推出的通用型厚膜贴片电阻,采用1210标准封装,针对中小功率电子电路的限流、分压、匹配等基础功能优化设计,兼具成本优势与环境适应性,是工业级、消费电子及车载领域的常用被动元件之一。
该型号属于厚膜电阻范畴,区别于薄膜电阻的高精度特性,更侧重功率承载能力、批量成本控制与宽温度适应性,核心参数明确指向通用型电路需求:
820Ω阻值属于常用中值电阻,±5%的精度无需额外校准即可满足多数工业控制、电源电路的功能需求(如PLC输入接口的限流、DC-DC转换的反馈分压)。
500mW功率额定值支持连续工作状态下的热耗散,若电路中瞬时功率不超过1W(脉冲功率),仍可稳定运行;200V工作电压覆盖了常规220V市电降压后的次级电路电压范围,适配多数低压电路场景。
采用1210标准贴片封装(英制:0.12英寸×0.10英寸,公制:3.2mm×2.5mm),具备以下特点:
该型号针对工业级应用强化了可靠性设计:
结合参数特性,1210W2J0821T5E广泛应用于以下领域:
UNI-ROYAL(厚声)作为国内被动元件领域的成熟品牌,该型号具备:
综上,1210W2J0821T5E以高性价比、宽温适应性及稳定可靠性,成为中小功率电子电路中替代传统插件电阻的理想选择,覆盖多行业的通用应用需求。

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.
