FN15X681K250PNG 多层陶瓷电容(MLCC)产品概述

一、产品核心定位与身份

FN15X681K250PNG是PSA信昌电陶(国内MLCC领域成熟制造商)推出的一款通用型表面贴装多层陶瓷电容,针对中低电压、中等容量且对温度稳定性有明确要求的电路场景设计。其型号编码隐含关键参数:FN15为信昌电陶通用MLCC系列,X代表X7R介质,681表示容值680pF(68×10¹),K对应±10%精度,250为25V额定电压,PNG为封装/包装规格标识。

二、关键电气性能参数详解

该产品的核心电气指标适配通用电路需求,避免冗余精度与成本:

  • 容值与精度:标称680pF,精度±10%(K档)。无需额外校准即可满足电源滤波、信号耦合等场景的性能要求,平衡成本与实用性;
  • 额定电压:25V直流(DC)。实际应用需遵循电压降额原则(≤80%额定电压,即≤20V),可有效延长产品寿命,降低介质击穿风险;
  • 介质类型:X7R陶瓷介质,属于“温度稳定型”(区别于NPO高精度低容量、Y5V高容量宽容差),兼顾容量密度与环境适应性。

三、封装与物理特性

采用0402封装(英制命名,对应公制1005:1.0mm×0.5mm),是小型化设备的主流选择:

  • 体积优势:尺寸仅1.0mm(长)×0.5mm(宽)×0.5mm(典型厚度),可大幅节省PCB空间,适配蓝牙耳机、智能手环等便携设备的高密度贴装;
  • 贴装兼容性:表面贴装型(SMD),焊盘设计符合IEC 61061标准,兼容回流焊、波峰焊等常规SMT工艺,批量生产良率稳定;
  • 机械强度:多层陶瓷结构配合封装材料,可承受常规机械应力(跌落、振动),满足消费电子日常使用场景。

四、温度特性与环境适应性

X7R介质的温度稳定性是核心优势,符合EIA标准:

  • 工作温度范围:-55℃至+125℃,覆盖工业级(冬季低温、夏季高温设备内部)与消费电子级环境;
  • 容量稳定性:温度范围内容值变化≤±15%,远优于Y5V介质(±20%~-82%),确保电路性能在温度波动下保持稳定(如工业传感器节点、车载辅助电路)。

五、典型应用场景

因体积小、性能均衡,广泛应用于以下场景:

  1. 消费电子便携设备:蓝牙耳机、智能手表的电源去耦(消除高频噪声)、信号耦合电路;
  2. 小型通信模块:低功耗蓝牙(BLE)、WiFi模块的射频滤波、信号匹配电路;
  3. 工业控制传感器:温度/压力传感器节点的电源滤波,适配工业宽温环境;
  4. 小型医疗设备:血糖仪、血压计的电源电路,满足低功耗与稳定性需求。

六、品牌与可靠性背书

PSA信昌电陶的品质保障覆盖全生命周期:

  • 标准合规:符合RoHS 2.0、REACH环保指令,无铅封装(IEC 61249-2-21标准),适合出口产品;
  • 可靠性测试:通过高温老化(125℃×1000h)、高低温循环(-55℃+125℃×500次)、振动测试(102000Hz×2g),满足IEC 60384-1电容标准;
  • 产能稳定:具备成熟生产线,可满足中小批量到大规模生产的供货需求,避免供应链波动。

七、选型与使用注意事项

  1. 电压降额:实际工作电压≤20V,避免过压击穿;
  2. 温度匹配:若场景温度超出-55℃~+125℃,需更换介质(如NPO或Y5V);
  3. 精度调整:需±5%精度时选J档(如FN15X681J250PNG),此产品为K档(±10%);
  4. 焊盘设计:PCB焊盘建议0.8mm×0.6mm,避免虚焊或焊接不良。

该产品以“均衡性能+小体积+可靠品质”为核心,是消费电子、小型工业设备电路设计的高性价比选择。

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
