Surface Mount Multilayer Ceramic Capacitors (SMD MLCCs) for High Power Applications
Ultra HiQ-CBR Squared Series, C0G Dielectric, Low ESR
250 VDC, 1 MHz – 50 GHz (RF & Microwave)
Overview
KEMET’s Ultra HiQ-CBR 0505 Series surface mount
multilayer ceramic capacitors (MLCCs) in C0G dielectric
feature a robust and exceptionally stable copper electrode
dielectric system as well as a square case size that offers
excellent low loss performance (ultra high Q). These
devices provide extremely low ESR and high self-resonance
characteristics, and are well-suited for higher power
applications where minimal heating due to I

R losses
are a factor. CBR Series capacitors exhibit no change in
capacitance with respect to time and voltage, and boast a
negligible change in capacitance with reference to ambient
temperature. Capacitance change is limited to ±30 ppm/ºC
from −55°C to +125°C.
CBR Series devices are suitable for many circuit applications
including RF power amplifiers, mixers, oscillators, low noise
amplifiers, filter networks, antenna tuning, timing circuits,
delay lines, and MRI imaging coils.

When ordering CBR Series devices, a "suffix" or "C-Spec" is not required to indicate a 7" reel packaging option. CBR devices are only available and
shipped on 7" reels (paper tape). Bulk bag and cassette packaging options are not available. Please contact KEMET if you have a specific, non-
standard packaging requirement.

Insulation Resistance (IR) Limit at 25°C:
DWV is the voltage a capacitor can withstand (survive) for a short period of time. It exceeds the nominal and continuous working voltage of the
capacitor.

Capacitance and quality factor (Q) measured at 1 MHz ±100 kHz and 1.0 ±0.2 Vrms.

To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known
as Automatic Level Control (ALC). The ALC feature should be switched to "ON."
