TCC0402COG471J500AT 产品概述

一、产品简介

TCC0402COG471J500AT 为 CCTC(三环)系列高稳定性多层陶瓷贴片电容(MLCC),封装为 0402(约 1.0 mm × 0.5 mm),额定电压 50 V,标称电容 470 pF(代码 471),容差 ±5%(J),温度系数 C0G(又称 NP0)。该器件针对对温度稳定性、低损耗和长期可靠性有较高要求的精密电路设计。

二、主要特性

  • 容值:470 pF,精度 ±5%(J)
  • 额定电压:50 V DC
  • 温度特性:C0G/NP0(近似 0 ppm/°C,典型允许范围 ±30 ppm/°C),在 -55 ~ +125 ℃ 范围内保持稳定
  • 低介质损耗和高 Q 值,适用于高频与滤波场合
  • 极低电压系数与极小老化特性,适合定时、振荡器与精密滤波电路
  • 表面贴装 0402 小尺寸,适合高密度 PCB 布局

三、电气与机械参数(典型)

  • 容差:±5%(J)
  • 工作温度范围:常见 -55 ℃ 至 +125 ℃(请以具体出货规格书为准)
  • 寿命与可靠性:符合常见电子元器件可靠性测试(温度循环、湿热、机械冲击等)
  • 封装尺寸:0402(约 1.0 × 0.5 mm),厚度视具体工艺略有差异

四、典型应用场景

  • 高频滤波与匹配网络(射频前端)
  • 时钟振荡器与定时电路(对频率稳定性要求高)
  • 模数转换(ADC)和精密模拟前端滤波、去耦电容
  • 医疗、仪器仪表、工业控制与航空电子等对温度漂移和长期稳定性要求严苛的场合

五、设计与焊接建议

  • 推荐 PCB 焊盘设计应保证良好焊接填充与热膨胀余量;建议对 0402 使用与制造商推荐相近的焊盘尺寸与间隙以降低裂纹风险。
  • 回流焊工艺:遵循无铅回流温度曲线,峰值温度通常 ≤ 260 ℃,在液相线以上(>217 ℃)的时间不宜过长(建议 30–40 s);合理控制预热、回流和冷却坡度以减少热应力。
  • 装配注意:小尺寸封装易受机械应力与过热影响,贴装、波峰或手工焊接时避免弯曲或过力压迫。
  • 储存与防潮:为保证可焊性,出厂通常采用干燥卷带包装,长期储存应放置于干燥柜,避免潮湿与污染。

六、包装与合规

  • 常见包装形式为卷带(Tape & Reel),适配贴片机自动化装配。
  • 满足 RoHS 等环保指令(具体合规证书请参阅厂家数据手册)。

七、料号解析与采购建议

  • 料号 TCC0402COG471J500AT 分解示例:TCC(品牌) + 0402(封装) + COG(介质类型) + 471(470 pF) + J(±5%) + 500(50 V)+ AT(包装/工艺代码)。
  • 采购时建议向供应商索取完整数据手册与可靠性报告,确认温度范围、尺寸公差、损耗角正切(DF)及样品测试条件,以便在设计验证阶段进行对照测试。

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
