Knowles Capacitance Range Extension: Class I Ceramic C0G Series
Knowles has extended the range and performance of the Class I Ceramic C0G Series Capacitors to better support LLC type DC/DC converters in demanding environments. With a maximum capacitance of 44nF/1kV and 66nF/630V in a compact chip size of 1210, the extended series is well suited for enhancing stability in this application context. Knowles unique construction methods allow these VM2 capacitors to offer higher capacitance values in such a small chip size.
The VM2 series of C0G ceramic capacitors includes:
- 500V: 39nF – 66nF
- 630V: 39n – 66nF
- 1kV: 27nF – 44nF
Key Features & Advantages
- Extended Capabilities: Vertical novel internal electrode design increases performance when handling ripple current.
- Compact Size: Chip size 1210 (3.2 x 2.5mm) can reduce component count and potentially replace a two-chip stack configuration.
- Wide Operating Temperature Range: Available in an AEC-Q2000-qualified, industrial-grade operating range of -55°C to 125°C.
- Best-in-Class ESR: Exceptional equivalent series resistance (ESR) ensures thermal stability in high-current, complex layouts.
This range extension is driven by the growing demand for higher power density and more volumetrically efficient converters in both EV and industrial markets. Knowles has a long history of delivering MLCCs that perform reliably in the world’s most demanding environments. From industrial power systems to aerospace, defense, and medical electronics, Knowles MLCCs are designed and tested to withstand extreme temperatures, voltages, and vibration. Knowles’ commitment to high-reliability design and proven manufacturing quality ensures consistent performance when stability and longevity matter most.
