关键参数解析

X7R特性说明

• •

  X7R 属于Class II陶瓷电介质，具有中等稳定性，适用于温度变化不极端的环境（如消费电子、电源滤波）。

• •

  在-55°C ~ +125°C范围内，容量变化约为±15%（但实际产品标称容差为±10%）。

• •

  相比COG/NPO（Class I），X7R容量更大，但稳定性稍低；相比Y5V/Z5U（Class III），X7R更可靠。

应用场景

1. 1.

   电源去耦 & 滤波（如DC-DC转换器、LDO稳压器）

2. 2.

   信号耦合 & 旁路（如音频电路、传感器电路）

3. 3.

   消费电子（手机、平板、穿戴设备）

4. 4.

   通信设备（路由器、交换机、基站）

5. 5.

   汽车电子（非高温极端环境）

常见问题（FAQ）

Q1：C1608X7R1C474K080AC的容量是多少？

• •

  470nF（即0.47μF），编码规则：474 = 47 × 10⁴ pF = 470,000 pF = 470nF。

Q2：这款电容的耐压是多少？

• •

  16V DC，建议工作电压不超过额定值的50%~80%以延长寿命。

Q3：X7R和COG/NPO有什么区别？

Q4：0603封装的焊接注意事项？

• •

  推荐回流焊，避免手工焊接温度过高（建议<260°C）。

• •

  避免机械应力，防止PCB弯曲导致电容开裂。

Q5：如何辨别正品TDK电容？

• •

  正规渠道采购（如谷京科技提供原厂包装和可追溯的COO编码）。

• •

  外观检查：TDK电容印刷清晰，无模糊或偏移。
