### 0603 贴片电容的容值范围
对于0603尺寸(SMD)的多层陶瓷电容器(MLCC),常见的容值范围可以从几皮法(pF)到几十微法(uF)[^1]。具体来说:
- 容值通常覆盖从1pF至22uF不等。
- 额定电压则依据不同制造商而变化,一般介于4V至50V之间。
下列表格展示了部分标准规格下的典型参数组合:
| 容量 (Capacitance) | 额定电压(Voltage Rating) |
|--------------------|--------------------------|
| 1 pF | 50 V |
| 10 pF | 50 V |
| 100 pF | 50 V |
| 1 nF | 50 V |
| 10 nF | 50 V |
| 100 nF | 25 V / 50 V |
| 1 uF | 6.3 V / 10 V / 16 V |
| 10 uF | 4 V |
值得注意的是,并非所有可能的容量和耐压组合都存在实际产品;某些特定数值可能是专有的或是由个别供应商提供。因此,在选择合适型号前建议查阅目标厂商的数据手册获取最准确的信息。
```python
# Python code to demonstrate a simple lookup function for capacitance values of 0603 SMD capacitors.
def find_capacitor(cap_value, voltage_rating):
# A simplified dictionary representing available 0603 MLCCs with their nominal capacity and rated voltages.
cap_dict = {
"1p": {"voltage": ["50"]},
"10p": {"voltage": ["50"]},
"100p": {"voltage": ["50"]},
"1n": {"voltage": ["50"]},
"10n": {"voltage": ["50"]},
"100n": {"voltage": ["25", "50"]},
"1u": {"voltage": ["6.3", "10", "16"]},
"10u": {"voltage": ["4"]}
}
key = f"{cap_value}f".replace(' ', '')[:2].lower() # Convert input into format like '1pf', '1nf' etc.
if key not in cap_dict or str(voltage_rating) not in cap_dict[key]["voltage"]:
return None
return True
print(find_capacitor("1 u", 10)) # Example usage checking availability of 1µF at 10V rating.
