0603B684K160CT多层陶瓷电容器产品概述

一、核心参数概览

0603B684K160CT是华新科(Walsin)推出的表面贴装多层陶瓷电容器(MLCC),其核心参数与型号标识对应清晰:

  • 容值:680nF(型号中“684”表示68×10⁴pF=680nF=0.68μF);
  • 精度:±10%(标识“K”);
  • 额定电压:16V DC(型号中“160”为16V简化标识);
  • 温度系数:X7R(-55℃~+125℃范围内容值变化±15%);
  • 封装尺寸:0603英寸(对应公制1608,即1.6mm×0.8mm);
  • 基本类型:无极性表面贴装MLCC。

二、产品基础属性

作为华新科主流消费级MLCC产品,0603B684K160CT具备以下基础属性:

  • 品牌与工艺:华新科采用成熟的多层陶瓷叠层工艺,通过高精度印刷、叠层、烧结实现小体积下的高容值;
  • 封装适配:0603封装是SMT生产线的标准小尺寸封装,兼容大多数PCB设计的高密度布局需求;
  • 介质特性:X7R陶瓷介质属于“温度稳定型”,介于高频稳定的NPO(C0G)和低成本的Y5V/Y5P之间,兼顾性能与成本优势。

三、关键性能特性

  1. 宽温稳定性:X7R介质支持-55℃~+125℃工作温度,容值变化控制在±15%以内,可适应户外、工业等温度波动场景;
  2. 电压适应性:额定16V DC满足多数低压电路需求,实际应用中建议按80%降额(≤12.8V)使用,延长使用寿命;
  3. 精度可靠性:±10%精度可满足滤波、耦合、旁路等基础电路需求,无需额外校准,降低设计复杂度;
  4. 小体积高密度:1.6mm×0.8mm封装仅为指甲盖的1/50,适合智能手机、智能穿戴等小型化设备的空间优化;
  5. 焊接兼容性:耐回流焊温度(峰值260℃,持续10s),适配自动贴装生产线,手工焊接需控制烙铁温度≤350℃,避免介质开裂。

四、典型应用场景

该产品因性能均衡、成本可控,广泛应用于以下领域:

  1. 消费电子:智能手机主板的电源滤波(如CPU供电模块)、蓝牙耳机的音频耦合、智能手表的传感器信号调理;
  2. 通信设备:路由器/交换机的电源模块滤波、小型基站的射频电路旁路;
  3. 工业控制:小型PLC的I/O接口滤波、传感器节点的电源稳压;
  4. 物联网设备:智能家居节点(如温湿度传感器)的电源管理滤波、智能门锁的信号耦合。

五、选型与应用注意事项

  1. 电压降额:严禁工作电压超过16V,长期过压会导致介质老化甚至击穿;
  2. 温度范围:若应用环境温度超出-55℃+125℃,需更换为X8R(-55+150℃)或车规级产品;
  3. 容值匹配:680nF适合中低频(10kHz~100MHz)滤波,高频(>100MHz)需搭配小容值NPO电容;
  4. 极性注意:MLCC无极性,但部分高压型号需注意方向,此产品无极性可正反贴装;
  5. 批量采购:建议按整盘(通常10000片/盘)采购,适配SMT生产线的飞达供料。

六、产品价值与优势

  1. 性价比突出:华新科作为国内主流MLCC厂商,产品价格比进口品牌(村田、TDK)低15%~20%,适合中低端到中端应用;
  2. 小体积大容值:0603封装实现680nF容值,是同封装下Y5V介质容值的1/2,但温度稳定性提升3倍;
  3. 生产适配性:0603封装是全球电子制造的通用规格,易采购、易焊接,降低供应链风险;
  4. 可靠性验证:产品通过AEC-Q200(非车规版)、RoHS等认证,符合环保与安全标准。

综上,0603B684K160CT是一款兼顾性能、成本与小型化的通用MLCC,适用于大多数低压电子设备的滤波、耦合等基础电路设计。

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
