0402WGJ0681TCE 厚膜贴片电阻产品概述

一、产品核心定位与适用场景

0402WGJ0681TCE是UNI-ROYAL(厚声) 推出的0402封装厚膜贴片电阻,主打小功率(62.5mW)、常规精度(±5%) 场景,平衡了性能与成本优势,适配对体积紧凑、布局优化有需求的通用电子电路。该产品依托成熟厚膜工艺,是替代传统插件电阻、提升电路集成度的优选方案,可覆盖多数非超高精度的中小功率应用。

二、关键性能参数详解

产品核心参数明确,可满足多数通用电路的设计要求:

  1. 阻值与精度:标称阻值680Ω(电阻代码标注为“681”,遵循“前两位有效数字+第三位倍率”规则,即68×10¹=680Ω),精度等级±5%,无需额外校准即可适配信号调理、分压、限流等常规应用。
  2. 功率与电压额定值:额定功率62.5mW,最大工作电压50V;使用时需同时满足“实际功耗≤62.5mW”与“两端电压≤50V”,避免过载导致性能下降。
  3. 温度系数(TCR):±100ppm/℃,表示温度每变化1℃,阻值变化量为标称值的±100×10⁻⁶(即680Ω×100e-6=0.068Ω/℃),保证宽温区下电路稳定性。
  4. 工作温度范围:-55℃~+155℃,覆盖工业级设备常规温区,可适应高低温交替环境(如户外监控、工业传感器模块)。

三、封装与物理特性

采用0402英寸贴片封装(公制尺寸:1.0mm×0.5mm×0.3mm),是小型化电子设备的主流封装之一:

  • 体积紧凑:可有效降低电路板占用面积,提升电路集成度,适配智能手机、智能穿戴等小型设备。
  • 工艺兼容:厚膜电阻体附着于陶瓷基底,具备良好机械强度,兼容回流焊、波峰焊等SMT组装流程,生产效率高。
  • 重量轻:单颗电阻重量约0.005g,对设备轻量化设计友好。

四、可靠性与环境适应性

  1. 厚膜工艺优势:通过丝网印刷、高温烧结形成电阻体,相比碳膜电阻稳定性更强,相比薄膜电阻成本更低,长期使用阻值漂移小。
  2. 耐候性:陶瓷基底绝缘性、耐腐蚀性优异,可抵抗潮湿、粉尘等环境因素,延长使用寿命。
  3. 温区稳定性:-55℃~+155℃的宽温范围,避免因温度变化导致阻值异常,适配户外、工业等复杂场景。

五、品牌与品质保障

UNI-ROYAL(厚声)是国内专注被动元件研发生产的知名厂商,产品通过ISO9001、ISO14001 质量管理体系认证,符合RoHS、REACH环保标准:

  • 生产过程:每批次产品经过参数测试、可靠性筛选,确保一致性与稳定性。
  • 品质管控:从原材料到成品全流程检测,满足客户批量生产的品质要求。

六、典型应用领域

因体积小、功率匹配、成本可控,广泛应用于:

  • 消费电子:智能手机、平板电脑、智能穿戴的信号调理、电源分压电路。
  • 工业控制:小型PLC、传感器接口、数据采集模块的限流/分压电阻。
  • 汽车电子:车载信息娱乐系统、车身控制模块的辅助电路(需确认温区符合汽车级标准)。
  • 通信设备:小型基站、路由器的射频辅助电路(非高频场景)。

总结

0402WGJ0681TCE作为高性价比厚膜贴片电阻,凭借紧凑体积、稳定性能与可靠品质,成为通用电子电路优化布局的理想选择,可满足多数中小功率、常规精度应用的需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
