CSA0402C0G3R0C500GT 贴片电容产品概述

一、产品定位与核心参数

CSA0402C0G3R0C500GT是HRE芯声(HRE) 推出的高精度高频贴片电容,专为对容值精度、温度稳定性要求严苛的电子电路设计。核心参数明确:

  • 标称容值:3pF;
  • 额定电压:50V(直流/交流峰值兼容);
  • 温度系数:C0G(对应国际标准NPO);
  • 容值精度:±0.25pF;
  • 封装规格:0402(公制1005,即1.0mm×0.5mm)。

该型号聚焦“小体积+高精度+宽温稳定”三大核心,适配各类小型化、高性能电子设备。

二、封装与物理特性

采用0402贴片封装(SMD),无引线设计,尺寸仅1.0mm(长)×0.5mm(宽)×0.5mm(高,典型值),重量约0.002g,可显著降低电路布局空间,满足智能手机、智能穿戴等便携设备的小型化需求。

封装材料兼容标准回流焊工艺:峰值温度260℃±5℃(焊接时间≤10秒),波峰焊温度245℃±5℃(时间≤5秒),无焊接兼容性问题;同时符合RoHS 2.0、REACH环保标准,不含铅、镉等有害物质,适配全球市场准入要求。

三、电气性能核心优势

  1. 高精度容值:±0.25pF的精度远优于普通陶瓷电容(如X7R精度多为±5%~±10%),可避免因容值偏差导致的电路匹配误差;
  2. 低损耗特性:C0G介质为低损耗陶瓷,典型损耗角正切值(tanδ)≤0.0001(1kHz下),适合射频、微波电路的信号传输,减少能量损耗;
  3. 高绝缘电阻:典型值≥10¹²Ω(25℃、50V直流下),可有效抑制漏电流,提升电路可靠性;
  4. 宽频响应:谐振频率高(典型值≥10GHz),支持高频信号(如2.4GHz、5GHz频段)的滤波、匹配应用。

四、温度稳定性解析

C0G温度系数为**±30ppm/℃**(IEC 60384-1标准),是陶瓷电容中温度稳定性最优的类别之一。在-55℃至+125℃的宽温范围内,容值变化率仅±0.15%(即3pF容值变化≤0.0045pF),远超X7R(±15%)、Y5V(±82%)等介质电容。

这一特性使产品可稳定工作于车载电子(-40℃+85℃)、工业控制(-25℃+85℃)等严苛环境,避免因温度变化导致的电路性能漂移。

五、典型应用场景

基于“高精度、宽温稳定、小体积”的特点,该电容广泛适配以下场景:

  1. 射频通信:蓝牙、WiFi、5G模块的滤波网络、阻抗匹配电路;
  2. 精密仪器:示波器、信号发生器的探头电容、参考振荡器;
  3. 消费电子:智能手机射频前端、智能手表传感器信号调理;
  4. 工业控制:PLC输入输出接口滤波、温度传感器信号滤波;
  5. 医疗设备:监护仪、心电图机的信号隔离、滤波电路(符合医疗级可靠性要求)。

六、品质与可靠性保障

HRE芯声对该产品实施全流程品质管控:

  • 生产过程:自动贴片封装设备+±0.05pF容值分选,确保出厂精度;
  • 可靠性测试:1000小时高温寿命测试(125℃、额定电压),容值变化≤±0.1%;
  • 环境测试:通过温度循环(-55℃+125℃,500次)、振动测试(102000Hz,2g加速度),满足IEC 60068标准。

产品提供1年质保,支持定制化参数(如不同封装、电压等级)。

该型号以“小体积实现高精度宽温稳定”为核心优势,是高频、精密电子领域的实用型选择。

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
