FAQ
Q1: What is the metric equivalent of 0402?
A: 0402 imperial is equivalent to 1005 metric, with a nominal body size of 1.0 × 0.5 mm.
Q2: What is the imperial equivalent of 1608?
A: 1608 metric is equivalent to 0603 imperial.
Q3: Does 0603 always mean the same package?
A: No. 0603 can mean imperial 0603 or metric 0603, depending on the naming system. Imperial 0603 equals metric 1608, while metric 0603 equals imperial 0201.
Q4: Is MLCC case size the same as capacitance value?
A: No. Case size only describes the physical package. Capacitance, voltage rating, dielectric type, tolerance, and temperature characteristics must be checked separately.
Q5: Can I use this converter for PCB footprint selection?
A: Use it as a quick reference only. Always confirm the recommended land pattern from the MLCC manufacturer datasheet.
Q6: Which MLCC case sizes are most common?
A: 0402, 0603, 0805, and 1206 are commonly used in many PCB designs, depending on board space, assembly process, capacitance, and voltage requirements.
