CDR31BP330BKUM

The CDR31BP330BKUM is a military-grade ceramic capacitor manufactured by Kyocera AVX, designed in accordance with MIL-PRF-55681 specification. It belongs to the CDR31 style, offering a compact 0805 (2012 metric) surface mount package. This capacitor features a C0G (NP0) dielectric, which provides ultra-stable capacitance over temperature and voltage, with a temperature coefficient of 0 ±30 ppm/°C over the full -55°C to +125°C operating range.

Electrical specifications include a nominal capacitance of 33 pF with a tolerance of ±10% (code K), a rated voltage of 100V DC, and a failure rate level of 1.0% (code M). The termination finish is base metallization-barrier metal-solder coated with tin/lead alloy containing a minimum of 4% lead, ensuring reliable solderability.

Mechanically, the capacitor measures 2.00 mm in length, 1.25 mm in width, and a maximum thickness of 1.3 mm. The termination band ranges from 0.50 mm minimum to 0.70 mm maximum. It is designed for surface mount assembly and is available in tape and reel packaging.

This component is suitable for high-reliability applications in military, aerospace, and industrial environments where stable capacitance and low losses are required. The C0G dielectric makes it ideal for timing, coupling, and filtering circuits.
