华新科0402X104K100CT陶瓷电容器产品概述

一、产品基本信息

华新科(Walsin)作为国内被动元器件领域的核心厂商,其0402X104K100CT是一款通用型多层陶瓷电容器(MLCC),专为低电压、高密度电路设计。该产品核心参数明确:容值100nF(标注“104”,即10×10⁴pF)、精度±10%、额定电压10V、温度系数X5R,封装采用0402英制(对应1005公制,尺寸1.0mm×0.5mm),是消费电子、便携设备的主流选型之一。

二、关键技术参数解析

  1. 容值与精度:100nF是电子电路中电源滤波、信号耦合的“黄金容值”,±10%的精度可覆盖绝大多数通用场景(如数字电路去耦、模拟信号滤波),无需额外承担高精度(±5%)的成本;
  2. 额定电压:10V额定电压适配低电压系统(3.3V、5V电路为核心应用),实际工作电压建议控制在额定值的80%以内(≤8V),避免电压波动导致击穿;
  3. 温度系数X5R:该系数表示产品在**-55℃+85℃**范围内,容值变化幅度≤±15%,相比Y5V(±20%±80%)稳定性显著提升,可适应户外、工业环境的温度波动;
  4. 封装规格:0402封装体积仅为传统0603封装的1/4,1.0mm×0.5mm的尺寸可大幅节省PCB空间,支持高密度布线,完美适配智能手机、智能穿戴等轻薄化设计。

三、产品核心特性

  • 小型化高密度适配:0402封装实现了“小体积大容值”的平衡,可在有限PCB面积内布局更多元器件,满足便携设备的紧凑设计需求;
  • 温度稳定性优异:X5R温度系数确保产品在宽温范围内性能稳定,避免因温度变化导致容值偏移,影响电路滤波、耦合效果;
  • 低损耗高频特性:多层陶瓷结构具备低介电损耗,适合中高频信号的滤波、耦合(如WiFi、蓝牙模块的射频辅助滤波);
  • 环保与可靠性:产品符合RoHS 2.0、REACH等环保标准(无铅无卤),华新科自动化生产工艺确保一致性,平均失效时间(MTBF)满足工业级要求,长期可靠性有保障。

四、典型应用场景

  1. 消费电子终端:智能手机、平板电脑、笔记本电脑的电源去耦(CPU、内存周边)、信号耦合(音频接口、USB电路);
  2. 智能穿戴设备:蓝牙耳机、智能手环、智能手表的低电压电路(MCU供电、传感器滤波);
  3. 小型通信模块:WiFi、蓝牙、NB-IoT等无线模块的电源滤波、射频辅助滤波;
  4. 工业控制小模块:小型PLC、传感器节点的低电压信号处理电路(ADC/DAC滤波)。

五、选型与使用注意事项

  • 电压余量考量:实际工作电压需低于额定电压的80%,避免电压尖峰击穿;
  • 温度范围适配:若环境温度超过85℃,建议选择X7R(+125℃)或更高温度系数的产品;
  • 焊接工艺要求:0402封装优先采用回流焊(避免手工焊易虚焊),回流温度曲线需符合华新科推荐(峰值温度240℃~260℃);
  • 存储与搬运:需存储在干燥环境(湿度≤60%),使用防静电包装与工具,避免静电损伤。

总结:华新科0402X104K100CT凭借小型化、稳定的温度特性及通用参数配置,成为低电压电子设备的高性价比选型,广泛适配消费电子、智能穿戴等领域的电路设计需求。

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
