1210W2J0821T5E厚膜贴片电阻产品概述

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。

一、产品核心定位与基础属性

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:

  • 阻值:820Ω(贴片标识“821”,对应“82×10¹”的三位数字编码规则);
  • 精度:±5%(标识中“J”为精度等级代号,匹配工业级电路对阻值偏差的容差要求);
  • 功率:500mW(1/2W),满足多数中小功率模块的功耗设计;
  • 电压等级:200V最大连续工作电压,避免过压击穿风险。

二、关键技术参数深度解析

1. 阻值与精度

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)。

2. 功率与电压

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。

3. 温度特性

  • 温度系数(TCR):±100ppm/℃,即温度每变化1℃,阻值变化约0.0082Ω,在-55℃~+155℃的宽温范围内,最大阻值偏差约1.72Ω,远低于±5%的精度要求,确保温度波动下电路性能稳定;
  • 工作温度范围:覆盖工业级环境的极端温度(如车载冬季低温、夏季高温,工业现场的昼夜温差),无需额外散热设计即可稳定工作。

三、封装与物理特性

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:

  • 体积紧凑:适合高密度PCB布局(如智能手机、路由器等小型化设备);
  • 厚膜工艺:通过丝网印刷、烧结等工艺在陶瓷基板上形成电阻膜,相比薄膜电阻成本降低30%以上,同时保持较好的功率承载能力;
  • 焊接兼容性:端电极采用镍/锡镀层,兼容回流焊、波峰焊等常规SMT工艺,焊接后抗拉强度≥10N,可靠性符合IPC-A-610标准。

四、环境适应性与可靠性

该型号针对工业级应用强化了可靠性设计:

  • 抗机械应力:厚膜电阻的陶瓷基板结构抗冲击、抗振动能力强,通过振动测试(10~2000Hz,加速度2g)后阻值变化≤0.5%;
  • 长期稳定性:经过1000小时高温老化测试(155℃),阻值漂移≤1%,满足设备5年以上的使用寿命要求;
  • 环保合规:符合RoHS 2.0、REACH等国际环保标准,无铅无镉,适配出口产品需求。

五、典型应用场景

结合参数特性,1210W2J0821T5E广泛应用于以下领域:

  1. 工业控制:PLC输入输出模块的限流电阻、传感器信号调理电路的分压电阻;
  2. 消费电子:电源适配器的反馈回路、音频放大器的偏置电阻、智能家居设备的控制电路;
  3. 车载电子:仪表盘背光电路、车载蓝牙模块的信号匹配电阻(宽温特性适配车载环境);
  4. 通信设备:基站射频模块的辅助电路、路由器的电源分配电路;
  5. 小家电:电磁炉、电饭煲的温度控制电路、电动牙刷的充电电路。

六、品牌与品质保障

UNI-ROYAL(厚声)作为国内被动元件领域的成熟品牌,该型号具备:

  • 供货稳定性:月产能千万级,可支撑客户批量生产;
  • 品质一致性:每批次100%阻值分选、功率老化测试,参数离散性≤0.3%;
  • 售后支持:提供技术文档、样品测试及批量问题响应,降低客户选型与生产风险。

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。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
