TCC0603X7R564K500CT 产品概述

一、产品简介

TCC0603X7R564K500CT 是三环(CCTC)系列的一款贴片多层陶瓷电容(MLCC)。其标称电容值为 560nF(代码 564),初始容差 ±10%,额定直流电压 50V,介质材料为 X7R。器件采用 0603(常用公制尺寸 1608)贴片封装,厚度 0.8mm,适合高密度贴装的中高容量去耦、滤波与储能应用。

二、关键参数与电气特性

  • 标称容量:560 nF(0.56 µF)
  • 容差:±10%(在 25°C 下的初始容差)
  • 额定电压:50 V DC
  • 介质类型:X7R(工作温度范围 -55°C 至 +125°C,温度下容量变化一般不超过 ±15%)
  • 封装/尺寸:0603(约 1.6 mm × 0.8 mm),厚度 0.8 mm
  • 品牌:CCTC(三环)
  • 封装终端:常见为镀银或镍焊锡终端(具体材料与工艺请以出货数据手册为准)

说明:X7R 属于类 II 陶瓷介质,具有较高的比电容,可在较小封装下实现较大容量,但在温度、偏置电压和频率条件下容量会有可观的变化。器件标注的 ±10% 为额定电容在室温下的公差;X7R 在 -55°C 至 +125°C 的温度范围内允许的容量偏差规范为 ±15%。

三、性能注意事项

  • 温度特性:X7R 在整个规定温区内容量变化不超过 ±15%,但在极端温度靠近上下限时可能接近此上限。
  • 电压依赖性(直流偏置效应):对类 II 陶瓷,随着直流电压增加,容量会下降。560 nF 在 50V 额定条件下可能出现明显的容量衰减,实际的保留率与具体材料配方、片型厚度有关,建议在电路设计时预留裕量并参考厂方的 DC-bias 曲线。
  • 频率特性与 ESR/ESL:0603 尺寸下的 MLCC 具有较低的等效串联电阻(ESR)和等效串联电感(ESL),在高频去耦和旁路应用中表现良好。但对于需要精密低损耗或高稳定性的滤波器、谐振回路,需评估其频率响应。
  • 寿命与可靠性:陶瓷电容通常具有长期稳定性,但受温度循环、机械应力与焊接热循环影响,建议遵循厂家的焊接与储存规范。

四、典型应用场景

  • 电源旁路与去耦:用于 MCU、模拟芯片、射频模块的局部去耦,抑制电源噪声和瞬态电流。
  • 信号滤波:与电阻配合用于低频或中频的旁路滤波电路。
  • 母线旁滤与储能:在空间受限但需一定瞬间储能的电路中可作为补偿电容。
  • 通用电子设备:家用电子、消费类产品、工控设备中的通用旁路/去耦元件。

注意:若用于汽车或工业级高可靠性场合,请确认器件是否通过 AEC-Q200 或相应认证。

五、封装与工艺建议

  • 焊接工艺:推荐采用标准回流焊工艺,严格控制回流曲线以避免热应力。若器件或卷带在高湿环境下存放时间过长,请按厂方说明进行烘烤除湿后再贴片焊接。
  • PCB 布局建议:
    • 去耦电容尽量靠近供电引脚和地平面,缩短电流回路以降低寄生电感。
    • 对于大容量滤波,建议与若干小容量低 ESL 电容并联,以覆盖更宽的频率范围。
  • 封装尺寸:0603 适合中高密度组装,脚位设计请参考 0603 标准尺寸留足焊盘,考虑焊膏印刷量以避免焊接缺陷。
  • 机械应力:避免在装配过程中对电容施加过大弯曲或压迫,防止裂纹导致性能下降或失效。

六、选型与采购建议

  • 若电路对温度和电压下的容量稳定性要求较高,考虑使用温度系数更稳定或电压依赖性更低的器件(如 NP0/C0G 或特殊配方的类 II 陶瓷)。
  • 由于数据受制造批次影响,采购前建议索取并核对厂方 Datasheet(特别是 DC-bias 曲线、寿命测试数据与端子材料信息)。
  • 若需汽车级、医疗级或军工级可靠性,请在订购时明确认证与资格要求,并与厂商确认。

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
