CERAMIC CHIP MIL-PRF-123 KEMET CHARGED

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview

The datasheet titled “CERAMIC CHIP MIL-PRF-123 KEMET CHARGED” presents technical information on KEMET’s ceramic chip capacitors that comply with military specification MIL-PRF-123. These capacitors are used in applications requiring reliable and precise performance within military standards. Key aspects of these capacitors include their dimensions, ordering information, and temperature characteristics.

Capacitor Outline and Dimensions

KEMET outlines the dimensions of the ceramic chip capacitors, providing measurements for length, width, thickness, and marking styles. Tolerances for the solder-coated termination are included, with specific additions to the positive width, thickness, and length tolerances for different chip sizes, such as the CKS51 to CKS57. Capacitors feature maximum thickness ranging from 0.050″ to 0.250″ and are legibly marked with the KEMET trademark and a 2-digit capacitance symbol.

Ordering Information

The datasheet details the ordering code format which includes the ceramic chip size, termination type, failure rate, temperature characteristic, capacitance, tolerance, working voltage, and temperature characteristic stability. For example, terminations can either be nickel-guarded solder-coated (Sn60) or 70/30 Tin/Lead plated. Failure rates are not applicable for these standard components.

Options for temperature characteristics include ultra-stable and stable, with designators ‘BX’ and ‘BZ’, showing capacitance change with temperature measured with and without DC bias voltage. The stability is defined in parts per million per degree Celsius (ppm/°C), indicating the precision of the capacitor’s performance over a temperature range.

Capacitance and Voltage

Capacitance values are provided in picofarads, with a three-digit code specifying the value: the first two digits represent significant figures, and the third digit indicates the number of zeros to follow. Tolerance codes range from ±0.25pF to ±10%. There are two working voltage options available—50 volts and 100 volts—designated by ‘B’ and ‘C’ in the ordering code, respectively.

Temperature Range and Military Specifications

The ceramic chip capacitors operate within a military temperature range of -55°C to +125°C. Each component is associated with a specific military specification number and modification number that reference the most recent attributes of the part in accordance with the specification sheet.
