CL31B105KCHVPNE 多层陶瓷贴片电容(MLCC)产品概述

一、产品基本身份与核心定位

CL31B105KCHVPNE是三星电子(SAMSUNG)推出的通用型X7R介质多层陶瓷贴片电容(MLCC),隶属于三星CL31系列(1206封装核心产品线)。该产品针对中等电压(100V)、宽温度范围(-55℃~+125℃)的稳定容值需求设计,兼具1μF高容值与温度稳定性,是工业控制、汽车电子、通信设备等领域的主流选型之一,平衡了性能与成本,适配大规模SMT生产。

二、关键电气性能参数解析

  1. 容值与精度:标称容值1μF(编码“105”,即10⁵ pF),精度±10%(编码“K”),满足90%以上通用电路的误差要求;
  2. 额定电压:直流额定电压100V,交流应用需降额至70V以下(峰值电压≤100V),避免击穿失效;
  3. 损耗与绝缘:25℃、1kHz条件下,损耗角正切(tanδ)≤5%,绝缘电阻(IR)≥10⁴ MΩ·μF(50V DC下),保证电路低功耗与高抗干扰性;
  4. 频率特性:10kHz~100MHz范围内容值变化≤±5%,适配中等频率的滤波、耦合场景。

三、物理特性与封装规格

该产品采用1206英制贴片封装(公制尺寸3.2mm×1.6mm),是电子行业应用最广泛的封装之一,适配标准贴片设备:

  • 典型厚度:0.8mm(±0.1mm),兼容多数PCB板的布线密度(支持双面贴装);
  • 端电极结构:三层镍锡镀层(Ni barrier + Sn plating),无铅环保,焊接兼容性强(回流焊峰值温度260℃±5℃,符合IPC-7711标准);
  • 外观:灰色陶瓷本体,黑色端电极,便于SMT视觉检测与人工识别。

四、材料特性与温度稳定性

CL31B105KCHVPNE采用X7R钛酸钡基陶瓷介质,是MLCC中“温度稳定性+容值密度”的平衡选择:

  • 温度系数(TCC):-55℃+125℃范围内,容值变化≤±15%(远优于Y5V/Y5P等高介电材料的±20%±82%);
  • 介电常数(εᵣ):约2500,既保证1μF容值的实现,又避免高介电材料的“温度漂移”问题;
  • 老化特性:常温下容值年老化率≤0.5%,长期使用(10年以上)仍能保持性能稳定。

五、典型应用场景

结合电气与物理特性,该产品主要应用于以下场景:

  1. 工业控制:PLC输入输出模块、伺服驱动器辅助电源的100V直流滤波;
  2. 汽车电子:车载48V mild hybrid系统的低功耗滤波、仪表盘电源的EMI抑制;
  3. 通信设备:基站射频电路的信号耦合、光模块电源的去耦;
  4. 消费电子:LED驱动电源(100V以内)的高压滤波、机顶盒电源的噪声抑制。

六、品牌与可靠性保障

三星作为全球MLCC前三大供应商,CL31系列产品通过多项严苛测试:

  • 高温寿命测试:125℃、100V DC下,1000小时后容值变化≤±10%,绝缘电阻≥初始值的50%;
  • 温度循环测试:-55℃~+125℃循环500次,无陶瓷开裂、端电极脱落;
  • 环保认证:符合RoHS 2.0、REACH SVHC要求,无铅端电极,适配绿色制造;
  • 批量一致性:同一批次产品容值偏差≤±5%,适合大规模自动化生产。

七、选型与使用注意事项

  1. 电压降额:实际工作电压建议不超过额定电压的80%(≤80V DC),避免过压击穿;
  2. 焊接工艺:回流焊温度需严格控制(峰值260℃,时间≤10秒),避免局部过热导致陶瓷开裂;
  3. 机械应力:贴片后避免PCB板过度弯折(曲率半径≥10cm),焊接时吸嘴压力≤0.5N,防止碎裂;
  4. 储存条件:常温(25℃±5℃)、干燥(相对湿度≤60%)环境储存,开封后12个月内使用完毕,避免端电极氧化;
  5. 温度余量:高温场景(>100℃)需预留3%~5%容值余量,补偿温度导致的容值下降。

该产品凭借三星的可靠性背书与平衡的性能参数,成为中高端电子设备中“稳定型MLCC”的典型代表,适配多数需要中等电压、宽温稳定的电路设计。

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.
