CGA0402C0G4R0C500GT 产品概述
一、产品简介
CGA0402C0G4R0C500GT 是 HRE（芯声）系列的一款高稳定性薄膜多层陶瓷电容（MLCC），标称容值 4 pF，精度 ±0.25 pF，额定电压 50 V，介质材料为 C0G（亦称 NP0），封装尺寸为 0402（公制 1005）。该型号为小体积、低温漂、低电压系数的高频精密电容，适合对容值稳定性和温度特性要求较高的电路。
二、主要参数（要点）
- 容值：4 pF
- 公差：±0.25 pF（相当于约 ±6.25%）
- 额定电压：50 V DC
- 介质：C0G / NP0（温度系数接近 0 ppm/°C，属二类中最稳定的一类）
- 封装：0402（1.0 mm × 0.5 mm 典型尺寸）
- 品牌：HRE（芯声）
三、关键特性
- 温度稳定性强：C0G 介质在常用温区内表现出极低的温度系数和极小的容量漂移，适合对频率或定时敏感的应用。
- 低电压系数：在直流偏置下容值变化小，适合高精度模拟及射频电路。
- 低损耗、高 Q 值：在高频信号环境中表现良好，适用于滤波、谐振和阻抗匹配等场景。
- 体积微小：0402 封装便于在空间受限的 PCB 布局中使用，利于高密度装配。
四、典型应用场景
- 高频 RF 前端：谐振、调谐及阻抗匹配网络
- 精密振荡器与定时电路：对容值稳定性要求高的 LC 谐振回路
- 模拟电路：高精度滤波、采样与参考回路
- 通信设备、仪器仪表及移动终端等需要小体积高稳定元件的场合
五、使用与装配建议
- 焊接：建议按常规无铅回流工艺并遵循 IPC/JEDEC 推荐曲线，避免过高的峰值温度或过长的加热时间。
- 机械应力：0402 体积小但厚度薄，应避免在焊接前后对贴片施加过大机械应力（尤其是弯板或强烈震动），以防裂纹或失效。
- 清洗与储存：遵循制造商对潮湿敏感等级（如有）及包装说明，存放环境应避免高温高湿；清洗时使用推荐溶剂并避免强烈机械搅动。
- ESD 与过压防护：虽为陶瓷电容但仍建议在敏感电路设计中加以过压保护或串联限流元件。
六、采购与质量建议
选择 HRE（芯声）品牌时，请确认批次和原厂型号一致，必要时索取最新的规格书与可靠性测试报告（如高温储存、热冲击、焊接热稳定性等）。对于关键应用，建议进行来料检验（容值、绝缘电阻、DCL、损耗角正切等）以确保符合设计要求。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
