CSA0603C0G181J500JT 产品概述

一、产品简介

CSA0603C0G181J500JT 是 HRE(芯声)推出的一款高稳定性多层陶瓷电容(MLCC),额定容量 180 pF,精度 ±5%,额定电压 50 V,介质类型为 C0G(又称 NP0),封装 0603(1608 公制)。C0G 属于 Class I 温度补偿型介质,具有极低的温度系数和介电损耗,适合对频率响应与容量稳定性要求严格的精密电路。

二、主要特性

  • 容值:180 pF(标称 181 编码)
  • 精度:±5%(J)
  • 额定电压:50 VDC(500 表示 50 V)
  • 介质:C0G / NP0(温度系数约 ±30 ppm/°C)
  • 封装:0603(约 1.6 mm × 0.8 mm)
  • 损耗角正切(tan δ):极低(C0G 特性,适合低损耗电路)
  • 温度稳定性好,在典型工作温度范围(-55°C ~ +125°C)内容量变化极小
  • 极小的介电吸收与压偏特性(对直流偏压下容量变化敏感性低)

三、优势与应用场景

优势:

  • 温度和电压稳定性优异:C0G 材料在宽温度和电压范围内容量基本保持不变,适合精密电路。
  • 低损耗:介质损耗极小,保持高 Q 值,适合高频与滤波场合。
  • 小封装、高可靠性:0603 封装兼顾体积和可焊性,适合自动化贴装。

典型应用:

  • 高频滤波器、谐振回路、振荡与计时电路(石英替代、相位噪声敏感电路)
  • 高频耦合、阻抗控制与信号路径匹配
  • 精密模拟电路、采样与 ADC 前端、差分放大器去耦(对稳定性要求高时)
  • 消费类电子、通信设备、仪表仪表(“三表”)、照明驱动与工业控制等

注:由于 C0G 容量密度低,不适合作为大容量旁路或电源去耦(此类通常选择 X5R/X7R 等 Class II 产品)。

四、封装与标识说明

  • 尺寸:0603(1608 公制),常见外形尺寸约为 1.6 mm × 0.8 mm,厚度随具体制造工艺略有差异。
  • 型号解析建议:CSA(系列)0603(封装)C0G(介质)181(180 pF)J(±5%)500(50 V)JT(包装/卷带/工厂代码)
  • 包装:常见为带卷(Tape & Reel),适用于 SMT 自动贴装生产线。

五、焊接与可靠性注意事项

  • 工艺兼容性:兼容主流回流焊工艺。建议遵循焊膏供应商和 PCB 焊接曲线规范,避免过高峰值温度或反复高温循环。
  • 温度与机械应力:0603 为小型封装,贴片后应避免在 PCB 上对电容施加过大弯曲或拉伸应力;板边缘附近布板时应留有应力缓冲区。
  • 电气老化与偏压效应:C0G 型对直流偏压的容量衰减极小,但长期高电压运行仍建议进行实际电路验证。
  • 环境与储存:避免潮湿、高温长期存放;开封后建议尽快使用,贴装前按常规回流焊前处理焊膏与 PCB 表面清洁要求。

六、选型建议与使用要点

  • 精密、低损耗电路优先选用 C0G:若电路对相位噪声、定时精度、滤波特性要求高,C0G 是首选;若需要大容量旁路或去耦,应选择 X5R/X7R 类产品。
  • 电压裕量:额定 50 V,设计时应考虑工作电压与浪涌、电压尖峰,必要时留有裕量或并联保护元件。
  • 温度范围验证:虽然 C0G 在 -55°C~+125°C 内性能稳定,特殊极端应用(如高温发动机舱)建议额外验证。
  • 可靠性测试:在关键应用(汽车电子、医疗、通信基站等)应结合 HRE 提供的可靠性试验数据(如温度循环、湿热、焊接热稳定性)进行验证。

总结:CSA0603C0G181J500JT 是一款面向高稳定性与低损耗需求的 MLCC 器件,凭借 C0G 材料特性和 0603 小封装,适合精密模拟与高频应用场景。选择时请结合实际电压、温度与机械应力条件进行确认,如需更详细的电气或可靠性参数(如 S-参数、热循环数据、寿命测试报告),建议向 HRE(芯声)索取完整数据手册与样品测试。

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
