CSA0402C0G330J500GT 产品概述

一、产品简介

CSA0402C0G330J500GT 是 HRE(芯声)推出的一款高稳定性贴片多层陶瓷电容(MLCC),标称容值为 33 pF,容差 ±5%(J),额定电压 50 V,温度特性为 C0G(又称 NP0),封装尺寸为 0402(公制 1005)。该型号以低温漂、低损耗和优良的频率特性为主要特点,适用于对温度稳定性和电气特性有较高要求的射频与精密模拟电路。

二、主要规格与性能

  • 容值:33 pF
  • 容差:±5%(J)
  • 额定电压:50 V DC
  • 温度系数:C0G(典型温漂接近 0 ppm/°C,在 -55°C ~ +125°C 区间保持优异稳定性)
  • 封装:0402(适合高密度贴装)
  • 极化:无极性(适合交流耦合与旁路)
  • 温度与频率性能:低损耗、Q 值高、介质随温度和频率变化微小

三、关键特性与优势

  • 温度稳定性高:C0G/NP0 介质几乎无温度相关漂移,适合时间常数、滤波和谐振回路等精密应用。
  • 低介质损耗:在高频下能够维持较高 Q 值,适合射频、混频及滤波网络。
  • 小尺寸高可靠性:0402 封装便于高密度贴装,同时材料与工艺保证良好的机械强度与震动可靠性。
  • 低电压系数与低老化:施加电压时容值变化小,C0G 无明显老化效应,长期稳定性优良。
  • 兼容自动化生产:提供卷带包装,适合贴片机和回流焊工艺。

四、典型应用场景

  • 射频前端:谐振电路、匹配网络、滤波器
  • 精密模拟电路:振荡器、定时电路、参考网络
  • 高频旁路与耦合:高速数字接口、PLL、ADC/DAC 的去耦与耦合
  • 传感器与测量仪表:对温漂和稳定性敏感的测量通道

五、封装与工艺建议

  • 焊接建议:按无铅回流焊温度曲线进行工艺控制,避免过长高温暴露;具体回流曲线以厂方规格书为准。
  • PCB 布局:为降低寄生电感与串联电阻,尽量将电容靠近被去耦芯片的电源引脚短距离放置;在射频应用中注意走线与地平面完整性以保证匹配效果。
  • 并联使用:在宽频带去耦时可与更大容值电容并联,以覆盖不同频段的抑制效果。
  • 储存与贴装:建议按厂方关于湿敏等级(MSL)与干燥包装的要求处理,卷带包装适合 SMT 自动贴装。

六、可靠性与合规性

  • C0G(NP0)材料本身无明显老化,长期电容稳定性好,适合关键参数要求严格的场合。
  • HRE(芯声)系国产品牌,生产与检验流程满足常见电子元件质量管理与可靠性测试要求。产品通常符合无铅/RoHS 类环保指标,具体合规证书请参阅厂方资料。

七、选型与注意事项

  • 若电路对容值温度漂移和老化极其敏感,应优先选择 C0G 型号;若需要更大容值或更高耐压,可参考同系列其他规格。
  • 0402 尺寸适合高密度布局,但在手工焊接和维修时操作难度较大,建议批量生产采用自动贴装。
  • 对于高频设计,33 pF 在 0402 封装下自谐频率较高,适合用于匹配与耦合;如需更低自谐频率或更低 ESR,可评估更大尺寸或不同结构元件。

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
