CSA0603X7R681K500JT 产品概述

一、产品简介

CSA0603X7R681K500JT 是 HRE(芯声) 出品的一款贴片多层陶瓷电容(MLCC),规格为 0603(1608 公制),额定电压 50V,电容值 680pF,公差 ±10%,材料体系为 X7R。该产品适用于对体积与性能有较高要求的中高频去耦、滤波与耦合电路,兼顾体积小、可靠性好与成本优势。

二、主要规格与特性

  • 容值:680pF(标称)
  • 公差:±10%(K)
  • 额定电压:50V DC
  • 温度特性:X7R(-55°C 至 +125°C,温度变化影响范围按 X7R 标准)
  • 封装:0603(1.6mm × 0.8mm)表面贴装
  • 包装:卷带(JT 表示包装/端接代码,具体以厂家数据为准)
  • 主要特性:体积小、良好频率特性、中等介质常数、温度稳定性优于高K材料但不及 C0G;适合通用去耦与旁路应用。

三、电气与工艺注意事项

  • X7R 为类介质材料,电容随温度与直流偏置会发生一定变化,设计时应考虑温漂与偏压特性;在高电场下电容值可能显著下降。
  • 推荐采用无铅回流焊工艺,峰值温度通常 ≤260°C,具体回流曲线请参照厂商工艺规范。
  • MLCC 对机械应力较敏感,贴装、焊接与后段加工时避免弯折与应力集中;若长期在高湿环境存放建议预烘。
  • 若电路对精确度或长期稳定性要求较高(如计时、精密滤波),应优先选用 C0G/NP0 类型;X7R 更适合去耦、旁路与一般滤波场合。

四、典型应用场景

  • 数字电路与模拟电路的去耦与旁路(CPU、MCU、放大器电源滤波)
  • 高频滤波、阻抗匹配网络
  • 耦合/隔直电容(在允许的温漂范围内)
  • 消费电子、通信设备、工业控制等对体积与成本敏感的产品

五、订购与型号说明(参考)

  • 推荐型号:CSA0603X7R681K500JT
  • 料号含义(典型解释,最终以厂家数据为准):
    • 0603:封装尺寸;X7R:介质类型;681:电容量代码(680pF);K:±10%;500:表示 50V;JT:包装/端接标识。
  • 建议在批量采购前索取样品及完整规格书以确认回流、可靠性与环境测试数据。

六、包装、储存与可靠性建议

  • 常见为卷盘包装,适合自动贴片生产线;拆卷后按厂家建议使用时限与储存条件。
  • 存放环境建议干燥、避免阳光直射与强酸碱气体;必要时按 IPC/JEDEC 建议进行干燥处理(烘箱预烘)以防吸湿。
  • 对焊接、热循环、机械振动等可靠性要求高的项目,请参考 HRE 提供的可靠性试验报告(温度循环、湿热、机械冲击等)。

七、总结

CSA0603X7R681K500JT 为一款性能均衡的 0603 MLCC,680pF/50V 的规格适合多种去耦与滤波应用。选择时需考虑 X7R 的温漂与直流偏置特性,遵循厂商的焊接与储存工艺可获得稳定的使用表现。如需替代或批量技术验证,建议比较器件的温漂曲线和偏压特性,并向 HRE 获取详细规格书与可靠性数据。

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
