CGA2B2X7R1H331KT0Y0F 产品概述

一、概述

TDK 型号 CGA2B2X7R1H331KT0Y0F 是一款片式多层陶瓷电容(MLCC),规格为 0402 封装,标称电容 330 pF,公差 ±10%,额定电压 50 V,介质为 X7R。该元件属于常用的容值与电压组合,适用于空间受限的高密度布板,兼顾体积、成本与电气性能的折衷选择。

二、主要参数

  • 容值:330 pF(标称,25°C)
  • 公差:±10%
  • 额定电压:50 V DC
  • 介质:X7R(温度范围通常为 -55°C 至 +125°C,材料温漂特性在该温区内会有较大变化)
  • 封装:0402(约 1.0 mm × 0.5 mm,适用于高密度表面贴装)
  • 品牌:TDK(型号完整编码如上)

三、性能特点

  • 体积小、适合高密度 PCB 布局,0402 封装便于贴片自动化生产。
  • X7R 属于二类陶瓷介质,电容密度较高,适合去耦、旁路与一般滤波用途,但非精密温度稳定型(温漂在额定温区内可达 ±15%)。
  • 对直流偏压敏感:在较高偏压下实际电容值会显著下降,设计时需考虑 DC-bias 效应。
  • 存在老化现象:随时间按对数规律衰减,典型老化率约为每十倍时间量级约 1% 左右,具体值请以数据手册为准。
  • 适应常规回流焊工艺,但对机械应力敏感,需注意焊接与板面应力管理。

四、应用建议

  • 常用于电源去耦、芯片旁路、射频旁路(非高频精密)与一般滤波电路。
  • 不推荐用于需要高度温度/时间稳定性的定时或谐振电路,如精密振荡器或滤波网络(应选 NP0/C0G 或薄膜电容)。
  • 设计时若需保证在高偏压下的容量,建议进行 DC-bias 仿真或选用更高额定电压 / 更低介电常数产品,或并联多个电容降低等效 ESR/ESL。
  • 对于振动或热循环环境,建议在封装周围采取支撑或采用更耐振动的封装与工艺。

五、封装与可靠性

  • 0402 小尺寸带来板面节省,但同时对焊点质量与 PCB 裂纹更敏感。
  • 建议按照 TDK 数据手册执行回流曲线和预防机械应力的PCB处理(如减少板弯曲、避免近边缘布放)。
  • 储存与运输应避免潮湿、高温及强振动;上市前建议参考厂方出厂封装(卷带/盘装)与保管说明。

六、选型与替代

  • 若需要更好温度稳定性或低电压依赖特性,可考虑 NP0/C0G 系列。
  • 若对体积与容量有更高要求,可考虑 0201/0603 等不同封装或同厂其他额定电压版本。
  • 同类供应商(如 Murata、Yageo、KEMET 等)亦提供 0402、330 pF、50 V、X7R 的等效品,选型时请比对数据手册中的 DC-bias 曲线、ESR/ESL、老化特性与可靠性测试数据。

备注:本文为产品概述,具体电气特性曲线(温漂曲线、DC-bias、频率响应、可靠性测试数据)及封装尺寸、公差、回流焊承受能力等,请以 TDK 官方数据手册与规格书为准,并在设计中依据实际应用做验证测量。

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
